Think every family in the [[CrimeAndPunishmentSeries Crime And Punishment genre]] is on the [[TheMafia bad guys side]]? What if we reversed the equation? The Reagan family is a law enforcement family, not a robber family. A ''four-generational'' family within the UsefulNotes/NewYorkCity [[UsefulNotes/NewYorkCityCops Police Department]], with a retired Police Commissioner from YeGoodeOldeDays as the great-grandpa, current Police Commissioner Frank Reagan as ThePatriarch, his sons who are all cops and his daughter who is a DA. And ''their'' children (two of which have declared they are seriously considering joining the NYPD). They spend Sunday dinners together, quarrel, but stick by each other. Because the family that arrests together stays together.

They have different personalities. Grandpa Henry (Creator/LenCariou) is a hardbitten DaChief from the old days. Frank (Creator/TomSelleck) is an incorruptible patriarch and responsible police commissioner, who knows how to keep peace between his children and how to encourage them without giving undue favoritism. Danny (Creator/DonnieWahlberg) is a ruthless but competent homicide/major case detective who always catches the bad guys. Erin (Creator/BridgetMoynahan) is a stickler for points of law but she can also manipulate the law to advantage when seeking a conviction. And Jamie (Creator/WillEstes) is an idealist beat cop who feels a call to serve and protect. They are all loyal to each other and they all serve the cause of keeping order in New York City.

''Blue Bloods'' is a Creator/{{CBS}} CopShow with FamilyDrama elements that began airing in the Fall 2010 season. Its episodes typically interweave about three plot threads focusing on different parts of the family. The A-plot is almost always Danny and his current partner in a fairly standard PoliceProcedural Case of the Week, but the other threads vary widely by episode, from family drama around Erin's and Danny's children to Frank [[ToBeLawfulOrGood wrestling between his duties as police commissioner and his desire to do right by his family and city]], to Jamie's growth and maturation from rookie academy graduate to experienced patrol officer, and eventually training officer in turn to a rookie.

Not to be confused with the aristocracy, whose article is named BlueBlood.

!!This program provides examples of:

[[foldercontrol]]

[[folder:#-D]]
* TwentyPercentMoreAwesome: Rossellini promising Erin that he'll turn over a new leaf. "I'll change -- fifty percent."
* AbortedArc: Possibly a case of RealLifeWritesThePlot: the end of Season 3, involves Frank working with the NYC Public Advocate, a woman named Grace Newhouse who's thinking of running for Mayor. In fact, in the next episode [[spoiler: Mayor Poole is shot, and Ms. Newhouse becomes Acting Mayor until Poole leaves the hospital]]. Although she's apparently going to run for Mayor, she suffers ChuckCunninghamSyndrome. This might have been loosely based on the real life mayoral race in New York City at the time: the NYC Council President Christine Quinn was running to become the first female Mayor of New York, which may have inspired the Grace Newhouse character; during the summer hiatus, she lost ground in the Democratic primary to Bill de Blasio, and lost the race. It's possible that this persuaded the writers to drop the character inspired by her, and/or because they'd realized that Poole and his actor David Ramsey had become an EnsembleDarkhorse who had an interesting relationship with Frank.
* ActingUnnatural: In season 1, the Reagans are about to move against the Blue Templar, having linked a recent hit on a drug stash house to the Templar. Frank, however, orders Jamie to step aside and not participate. This is because Frank knows the Templar has eyes everywhere. Therefore, Jamie is to go about his day like it's any other day.
* ActuallyPrettyFunny:
** At the denouement of "Rush to Judgment" Frank dines with Gerry Guerrero, a civil rights attorney who works with Rev. Potter whom Frank had tangled with during the episode. Guerrero tells the waiter that Frank will have the crow; Frank promptly retorts, "Humble pie for my friend." Guerrero spends a good fifteen seconds looking like he can't decide whether to start swearing or laughing. (Of course, the scene is completely stolen by the ServileSnarker waiter asking them if he should come back with a completely straight face.)
** In "Bad Cop, Good Cop," Frank disciplines a patrol officer he spots texting and smoking on the job. Frank's staff are somewhat amused by the caricature of Frank that is posted in the media in response.
* TheAggressiveDrugDealer: Noble Sanfino trying to push some new party drug on Jamie, only to OD himself. He gets revenge by giving his dealer a near-fatal dose of his own product.
* AintTooProudToBeg: Roland Gates outed as an undercover cop.
-->'''Gates:''' I got two kids, man.\\
'''Shooter:''' Too bad for 'em.
* AllGirlsWantBadBoys:
** Erin gets weak in the knees when she meets an art aficionado. And she gets even weaker when he turns out to be an art thief who is using a fake alias. Frank is less than thrilled, but Erin tells him to mind his business.
** Averted with almost every other major female, however. Any woman drawn to Jamie (Sydney, Laura, Bianca) or Frank (Kelly, Melanie) is almost surely ''not'' looking for a bad boy, and although Danny might have shades of being a bad boy, Linda clearly appreciates his very real husband / parenting skills.
* AlwaysGetsHisMan: Frank and Danny.
* AmoralAttorney: DA Rossellini has his eyes on the Mayorship, and is happy to manipulate Erin in order to get it. And if the Mayor goes, Erin's father goes.
* AncestralWeapon: Frank's Fitz Special revolver, which was handed down from his Grandfather to Henry, and then to him. Danny also uses Henry's old not-quite-authorized/not-quite-legal slapper (essentially a small blackjack).
* ArrangedMarriage: Sammy Khan wasn't shot because of his anti-terror credentials, but because [[spoiler:a traditionalist Muslim already had dibs on his girl friend]].
* ArtisticLicenseGeography: Jamie operates out of the 12th precinct (itself a fictitious precinct due to the NYPD not allowing real precinct numbers to be used in works of fiction). However, it seems like the 12th precinct has a pretty large service area, including Manhattan, as well as parts of Brooklyn and Queens. In reality, if it existed, the 12th precinct's service area would be limited to a part of Lower Manhattan.
* ArtisticLicenseLaw:
** During the first two seasons, the police cars shown are replicas, bearing the obvious wrong font for the 'NYPD' lettering on the side[[note]]The real NYPD font is Rockwell Extra Bold; at a distance, the font on the replica cars looks similar, even is italicized, but is not Rockwell Extra Bold[[/note]], and bear a modified NYPD emblem that's also worn on the shoulder patches of replica uniforms[[note]]These emblems read "Police Department, New York" while the real emblems have the text "Police Department, City of New York"[[/note]]. This is more noticeable in some episodes where the replica cars appear alongside real-life NYPD police cars. Most of the time the precinct numbers on the real-life cars are not shown, since the NYPD does not allow real-life precinct numbers to be used in movies or TV shows[[note]]That's why in most shows that involve the NYPD will feature squad cars from the 15th or 27th precinct, regardless of what borough they take place in. These are numbers set aside for works of fiction so that the NYPD can distinguish replica patrol cars from patrol cars in their own vehicle pool[[/note]]. Only beginning in season 3 did the show got the approval to use replica cars with the correct patrol car font and emblems with the accurate wording.
** In several episodes, it is possible to see police cars with forward-facing blue lights. New York state law prohibits facing-forward blue lights on police vehicles. This is another thing done to differentiate real NYPD units from the movie cars.
** The NYPD Major Case Squad is depicted as operating at precinct level, out of the 54th Precinct[[note]]represented in exterior shots by the 25th Precinct in East Harlem[[/note]]. In reality, its detectives are stationed at One Police Plaza.
** Danny Reagan's normal on-duty weapon is a Smith & Wesson 5946 pistol, which is within NYPD regulations. However, he has as a backup weapon a Kahr [=K9=] 9mm pistol. The Kahr [=K9=] was an approved off-duty/backup weapon from 1998 to 2011. The NYPD had it pulled from service because it could not be modified to a 12-pound NY-2 trigger pull. Meaning, unless Danny got grandfathered in or Frank Reagan's policies differ from those of Raymond Kelly[[note]]The real life commissioner at the time[[/note]], Danny would have to turn in his Kahr [=K9=].
** Though a minor one: in general, most police officers and detectives find it very unprofessional to discuss current and open cases at the dinner table in front of family members, especially individuals like kids or spouses, given the sensitive nature of some investigations.
** After the officer funeral in "Unwritten Rules", we have a dinner table scene where police dress uniforms are all off:
*** Danny is seen at the dinner table in his Class A uniform with a 23 day beard. This would never happen as officers are required to look presentable in their Class As, which means he'd have to be clean-shaven.
*** Frank and Henry are seen in their white dress shirts as part of their uniforms while Danny is seen in his blue dress shirt. Jamie is wearing a white shirt like Frank and Henry. As a patrol officer, he would actually wear a blue dress shirt like Danny. White shirts are for members of the NYPD with the rank of Lieutenant or higher.[[note]]This is true in the NYPD even on-duty; uniformed personnel with the rank of Sergeant or Officer wear navy-blue shirts and pants. Anyone with the rank of Lieutenant or higher wears a white shirt.[[/note]]
** In "Partners":
*** Lieutenant James [=McCarthy=] is accused of excessive force when he has a crazed man stunned, and the guy falls into the path of an oncoming van and is killed. In real life, a crazed man wouldn't have been handled that way. Especially as soon as he spit at those pedestrians (in many states, spitting at someone constitutes assault), they would've probably tackled him to the ground. He also didn't have any type of weapon to endanger himself or others so the police officers could have just grabbed him, pulled him off the trash bins and then subdued him. Also, for the most part, police officers have moved away from handheld tasers to using gun tasers.
*** The situation for Jamie and Janko, where Renzulli sees Jamie's attacking the domestics perp as a guy defending a girlfriend more than a partner being defended, is a bit problematic. In real life, if the perp pushed Janko, she would have gotten more aggressive. If she even got pushed on the ground, Renzulli and the other officers on the scene would have rushed in to intervene, rather than just standing around and forcing Jamie to take care of it himself.
** In "Town Without Pity", Jamie and Janko come upon the body of a man who died alone in his apartment. Janko even goes and picks up evidence like a bag of money, to which Jamie says, "You shouldn't be touching that". In reality, it's standard procedure to treat unattended deaths as homicides until an autopsy can be done. Additionally, PPE (personal protective equipment) must be worn in a situation like that in the event the body had some type of contagion, as well as protecting any physical evidence like fingerprints. Jamie and Janko's first response should have been to secure the scene until detectives could arrive.
* ArtisticLicenseMedicine: In "The Art of War," after Curtis shoots Hector Flores, the medical team tries to revive Hector and someone orders CPR. CPR is not an appropriate treatment for cardiac arrest due to blood loss from a gunshot wound, as CPR causes increased blood flow. The appropriate treatment is to provide attempt to stanch the blood flow and provide the victim with an emergency blood supply and significant fluids via IV.
* ArtisticLicenseUniversityAdmissions: In "Loose Lips," Nicky is turned down for admission to Rutgers due to disparaging remarks she made on her Twitter account about one of her teachers. She had a personal interview with a Rutgers representative. Rutgers University does not interview individual undergraduate applicants. As a state university, the volume of applicants is too high for the system to do so. On the other hand, if she were applying to a private college of smaller than 2,000 students, there probably would have been an interview.
* AsianSpeekeeEngrish: In "Chinatown", Dannie and Jacky's suspect invokes this when he refuses to speak without his lawyer.
--> '''Suspect''': No speakee Engrish.
* AskAStupidQuestion: In "Leap of Faith", Danny thinks some small-town detectives could have been more thorough with the investigation of the ''first'' late Mrs. Bines.
-->'''Danny:''' And where was ''Mister'' Bines during all this?\\
'''Detective:''' Oh, right, I forgot to tell you. He was at the arsenic store.
* AssholeVictim:
** The son of a Russian mob boss is shot at his own engagement party. While cheating on his fiancée in the wine cellar. No great loss.
** The victims in the above-mentioned "Old Wounds" are rapists.
** The victim in "Mercy" is revealed to be a pedophile with a taste for Ukrainian hookers.
* AttemptedRape: In "Justice Served", this almost happens to Jamie's partner, who's reluctant to press charges at first for fear of looking weak in front of the male officers, but he eventually convinces her.
* AwesomeMcCoolname: Mobster Johnny Tesla.
* BadassFamily: Very much so. The best example of this is when Danny's wife is kidnapped by a drug lord: the family bands together and figures out where she is, allowing Danny and ESU to be BigDamnHeroes, and Erin finds the mole in the DA's office. Also, they have their own private code for when someone is being held hostage to drop so someone else can shoot. ''They practice this.'' Lampshaded when Danny's son asks fearfully if a burglar could target them.
-->'''Grandpa Henry:''' Are you kiddin'? He'll get one look at this table and run the other way.
* BadassMustache: Probably goes without saying since Frank is played by [[Series/MagnumPI Tom Selleck]].
* BadNewsIrrelevantNews: Danny and Jackie explain to a perp that the bad news is, they found his gun; he's headed for death row. The good news: they decided to drop the credit fraud charges.
* BaitAndSwitch: In "Excessive Force", after shooting his mouth off at a COMPSTAT hearing, Gormley receives word that he's being summoned to One Police Plaza and should bring his box with him. He goes there expecting Frank to fire him. Frank surprises him by instead [[{{Unishment}} promoting him to a new post on his staff]].
* BandOfBrothers: Naturally for a cop show. However this is deconstructed in a few episodes that highlight the blue code of silence -- to never rat on another cop who is engaged in misconduct. In "Forgive and Forget," Jamie temporarily partners up with Officer Cara Walsh, who's been shunned at the 12th Precinct for being a "rat" (her previous partner Randy Cutter killed a suspect in custody using an illegal chokehold and Frank had prodded her into admitting to seeing the incident). One night, they respond to an armed robbery at a pharmacy. When the thieves open fire on them, Jamie calls in a 10-13 (officer needs assistance), but the nearest patrol unit to respond to them is the one driven by Edie and her new temporary partner. Although the four manage to subdue the thieves, Walsh takes a bullet to the left shoulder. Subsequently, Jamie rightfully chews out a few fellow officers who were closer to the pharmacy but chose not to respond.
** Disturbingly, Henry believes in such behavior saying "cops shouldn't go against other cops" and he was commissioner during the time of the Knapp Commission -- aka when the department was it's most crooked (this is the period where renowned NYPD whistleblower Frank Film/{{Serpico}} comes from).
* BatmanGambit: In "Working Girls," Danny and Jackie are protecting a witness who's scheduled to testify against a Russian mobster who's had another witness killed. When a mole in the taskforce compromises the initial hiding place, they hide the witness at Jackie's apartment, but they don't tell anyone this other than Erin and Gormley. With Danny and Gormley unable to find the mole through background checks, they decide to plant a trail. Gormley gives an address out to the task force, knowing that the mole will notify the mob and they'll send assassins to kill the witness. The two hitmen go to an apartment complex, which seems to be Jackie's. They then kick down the door...[[BaitAndSwitch of an empty apartment]] inside which an ESU team is waiting for them. After a quick gunfight, the assassins are captured, and quickly give up the mole.
* BeamMeUpScotty: [[invoked]] Danny's reaction to his son asking if he's "[[PerpSweating sweating]]" a perp "in the box."
-->'''Jackie''': You've been [[YouWatchTooMuchX playing those video games again]], haven't you?
* BecauseYouWereNiceToMe: Jamie and Eddie once manage to get a witness to a shooting to talk after they take up a collection in their precinct to pay for the elderly, impoverished victim's funeral.
* BestServedCold: In "The Life We Choose," an undercover detective is killed during a botched drug buy by the Phantom, who is in town to exact revenge on [[OperationBlank Task Force Apache]], the cadre of cops and informants who sent him to jail.
* BetterToDieThanBeKilled:
** [[spoiler:Sonny Malevski tries to [[StopOrIShootMyself take himself hostage]]. Frank lets him shoot himself.]]
** The kidnapper in "My Little Valentine" leaps to his death rather than surrender to ESU.
** Billy Flood attempts to draw a sniper's fire in "Critical Condition." Danny [[AvertedTrope thwarts it]] by pushing him away.
* BigBrotherMentor: Ironically enough, not Danny, Jamie's actual brother; but Sergeant Renzulli, his training officer.
* BigNo: Danny, when a fellow officer and family friend is shot. ("The Life We Chose")
* BittersweetEnding:
** "Innocence". The wrong man was convicted of rape; while he's exonerated 18 years of his life are gone. Meanwhile the real rapist can't be prosecuted due to the 5-year statute of limitations, and has raped again ... but this time, he's on Frank's radar.
--> I'll be watching you. And so will the thirty five thousand police officers in this city.
** Similarly, "The Price of Justice". Because an abuse victim is reluctant to press charges against her abuser (since she doesn't want to testify), Danny, Baez, and Erin are unable to arrest him. However, the guy is now on police radar, and Danny is shown dissuading another woman the guy is trying to pick up.
* BlackBossLady: Lieutenant Dee Ann Carver, Danny's new supervisor after Gormley is promoted to 1PP.
* BlackDudeDiesFirst: The undercover operation in "The Life We Chose" is botched when the Phantom shows up and shoots the two undercovers doing the drug buys. The Hispanic detective, Detective Cruz, survives, but the black undercover, Detective Gates, is killed.
%% * {{Black Widow}}er: "Leap of Faith."
* BlastingItOutOfTheirHands: {{Discussed|Trope}} and mocked after Jamie's first line-of-duty kill (it also turns out to be a SuicideByCop case). A reporter at a press briefing asks Frank why Jamie shot to kill instead of trying to shoot the gun out of the man's hand. Frank just sort of gives him an exasperated look before explaining that Jamie followed department policy, which is to shoot at the torso and keep shooting until the threat is neutralized, even if the threat dies of his resulting injuries. Then, when the reporter keeps trying to press the issue, Frank shuts him up for good:
--> '''Frank''': There's a man in front of you waving a gun in your direction. You have a second to react. What do you do?\\
'''Reporter''': Well, first I'd--\\
'''Frank''': [''interrupts''] Too late. You're dead.
* BlingOfWar : NYPD uniforms have a party salad of decorations on a plate that also includes their badge. In a small subversion, the most prominent decoration is the one awarded to 9/11 first responders, a simple black bar with the letters "WTC".
* BloodSplatteredInnocents: In "Whistle Blower", the eponymous informant is shot in front of his wife. [[spoiler:Inverted when said wife is discovered to have known well in advance that her husband was about to be gunned down, having tipped off the man who hired the hit about her husband's work with the DA's office.]]
* BluntYes: A suburban detective, chafing at Danny's questions, receives this response from Danny.
-->'''Detective:''' [[SarcasmMode Since you're New York City Police Detectives, and I'm just a hick cop whose job consists of chasing drug dealers off the golf course.]]\\
'''Danny:''' That sounds about right to me.
* BookDumb: Sergeant Renzulli. "'Rhetoric?' I'm [[ExpospeakGag not familiar with the vernacular]]."
* BrandX: On several occasions, "Con Electric" utility trucks are shown being used, either as stakeout vehicles or as a robbery getaway cars. Ostensibly, it's the show's equivalent of Consolidated Edison, New York City's actual utility company.
* BreakTheCutie: Happening to Jamie more and more often.
** His first kill in the line of duty turned out to be a SuicideByCop.
** In "The Bitter End," [[spoiler:a gang lures him and his partner Vinny into a trap. Vinny is fatally shot and dies in Jamie's arms.]]
* ByTheBookCop:
** The father, Frank Reagan.
** Jamie is even more so.
* CallBack:
** Frank and Jamie's conversation while fishing in Episode 1 of Season 2, a callback to the pilot.
** "Love Stories" sees Danny and Baez receiving the Medal of Valor for the successful drug raid they carried out in "Partners".
** In "Home Sweet Home," Frank sprains his leg in a fall and is confined to his house for a few days. Henry remarks that it's the first time in four years that Frank has missed work. Frank says, "Last time, they had to shoot me," callback to "Dedications" where he was shot by Westies gang members.
** In "The Road to Hell", Danny is trying to talk a distraught Martina from jumping off a ledge. He recounts to her a similar incident with an army vet with PTSD, who ultimately took his own life because he couldn't live with what he had done[[note]] He attacked his wife and took their son with him, taking him to the ledge of a building. Seemingly unable to forgive himself, he gives a salute and jumps[[/note]]. Danny tells Martina that it's not worth it[[note]] She killed Pablo Gonzalez, the man who manipulated her[[/note]].
** In "Blowback," when an officer is shot in what seems like retaliation for the officer-involved shooting of a teenager, Mayor Carter Poole mentions that the surgeons who operated on the officer were the same ones who operated on Poole when he got shot in the Bitterman Project in the season 3 finale.
* TheCameo: The season 2 premiere sees Frank grudgingly attend a performance by Creator/TonyBennett and Creator/CarrieUnderwood. (To promote Bennett's second duet album.)
* TheCasanova: Sgt. Ray Langley, Jamie and Edie's training officer in "Stomping Grounds" has a habit of hitting on female officers under his command. After hearing that Langley hit on and kissed Edie, Jamie feels obligated to protect Edie and her career. He sees Langley as a predator who uses his position to make unwanted advances on fellow officers who were at a distinct disadvantage; at the end, he gathers a bunch of Langley's victims together, and intimidates the guy into putting in a transfer to Staten Island.
* CassandraTruth:
** In "Hall of Mirrors," a woman with [[SuperOCD OCD]] is convinced that a prowler keeps nudging her furniture around. [[spoiler:It turns out to be her brother, trying to [[{{Gaslighting}} gaslight]] her to get control of their parents' estate.]]
** A literal one in "Leap of Faith," wherein God "speaks" to the daughter of the murder victim.
* CelebrityParadox:
** The show is aired on CBS, yet on two occasions in the show, we see interviews with CBS anchors like Norah O'Donnell. So there's no explanation for what show replaces ''Blue Bloods'' in the in-universe programming lineup at CBS.
** "After Hours" has an offhanded reference made to Gordon Gekko, Michael Douglas' character in ''Film/WallStreet''. Tom Selleck appeared as a surgery patient in a 1978 movie called ''Film/{{Coma}}'', which also starred Michael Douglas.
** A reference is made to ''Series/MadMen'' by name in "Mercy". Several ''Mad Men'' cast members have guest-starred in ''Blue Bloods'', like Mark Moses (Duck Phillips), Michael Gaston (Burt Peterson), and Gary Baseraba (Herb Rennet).
** In "The Truth About Lying," Danny deals with a homeless man suspected of pushing a woman in front of a subway train (said woman turns out to have been committing suicide). The man is known as "the Hulk", ostensibly named after TheIncredibleHulk, because of his mental problems and how he acts when he has an outburst. Ostensibly, Danny's never watched ''[[Film/TheAvengers2012 The Avengers]]'' or he'd comment on how Sgt. Gormley (Robert Clohessy) looks a lot like one of the police officers Steve Rogers gave commands to in the climax. Not to mention that Gormley's replacement at the 54th, Lieutenant Carver, is played by [=LaTanya=] Richardson Jackson, the wife of Nick Fury actor Creator/SamuelLJackson.
* ChristianityIsCatholic: Justified. At least ''some'' are after all. They're also Irish.
* CitizenshipMarriage: {{Reconstructed}} in "Exiles". Jamie and Edie get called to deal with a domestic and encounter a Russian-American girl trying to overcome a ParentalMarriageVeto from her father so she can marry her Syrian boyfriend. The father thinks it's a sham. In the end he relents, but it turns out he was RightForTheWrongReasons. The boyfriend is actually gay and his life would be in danger if he returned to Syria (pictures of him partying with other men turned up on Facebook), so he married his platonic friend to get around ICE.
* ClearMyName:
** "Framed" sees the Reagan family work to clear Danny after he is framed for drug possession.
** In "Bad Blood," a police dog named Raymond is accused of biting a young boy. Frank takes a personal effort to exonerate the dog, in part due to the fact he used to serve in the Canine Unit until the dog he handled, Greta, was killed by a burglar he sent her after.
* ClintSquint: How Danny sizes criminals up.
* CombatPragmatist: Jamie's temporary partner Luisa Sosa in "Critical Condition" when they're assigned to a park stakeout involving a bag of goods left in plain sight as bait. When facing a guy bigger than her, she doesn't engage in GoodOldFisticuffs like Jamie: she pulls out a collapsible steel baton and hits him. Hard.
* TheComplainerIsAlwaysWrong: Anyone from a civilian to city official who criticizes the police department usually finds their criticisms are unfounded or wrong thanks to Frank.
* CommutingOnABus: Mayor Carter Poole does not appear much after season 3, since David Ramsey is a series regular on ''Series/{{Arrow}}''. He still makes recurring appearances.
* ConflictingLoyalty: Jamie is asked by the FBI to spy on a secret society for them that might include Danny.
* ConverseWithTheUnconscious: Frank and his [[OldFriend old squadmate]], John [=McKenna=], just as he's taken off of life support.
* CoolCar: The eponymous car from "The ''Film/{{Bullitt}}'' Mustang". The Reagan men can't stop drooling over it.
* CoolShades: Frank Reagan sports these.
* CopKiller:
** In "Officer Down" a patrol officer is gunned down when she blunders into the path of mafia-affiliated diamond thieves while coming back from lunch. TheMafia itself [[EnemyMine joins in hunting them down]], because cop killers [[PragmaticVillainy put the whole department on edge and make life difficult]]. An anecdote is recalled of a time where [[TheCoronerDothProtestTooMuch a cop killer was executed by the cops, and it was written off as a suicide]]. Grandpa Henry Reagan remarks that when he was on the force the mafia even had explicit rules that, outside of certain circumstances, cops were off-limits. The killer gets cornered, [[TooDumbToLive tries to shoot his way out]], and is hosed down with lead by several detectives and an ESU team.
** "The Life We Chose" sees Danny and fellow detectives Jackie Curatola, Jose Cruz and Roland Gates running an undercover drug operation. Danny and Curatola are "ghosts" who are tailing from afar, while Cruz and Gates are making the buys from a dealer. Things go bad when a mysterious guy named Phantom shows up, and shoots Cruz and Gates while they're doing the first buy. Cruz survives, but Gates is killed. It's worse because Gates was a father of three kids and his daughter was about to be christened.
** In "Most Wanted," a Serbian mob boss named Zorhan Brasha is arrested after he beats up a truck driver with a tire iron over a parking space. Frank is informed that Interpol would like Brasha to be extradited to Serbia to stand trial for crimes he's committed there. Frank, however, is insistent on Brasha getting tried and convicted for crimes he's committed in New York City. When Garrett asks why, Frank and Gormley explain that a few years earlier, Brasha [[DisproportionateRetribution slit an off-duty cop's throat over a spilt drink]], and then got away with it by having one of his henchmen take the fall for the crime.
** In "The Bitter End" Jamie and his partner Vinny Cruz are lured into an ambush in the Bitterman Projects by a Latino gang with a beef against the NYPD, and Vinny is killed. End of the next episode, the NYPD carries out a massive raid that results in the arrests of over 47 members and associates of the gang, including conspiracy to murder charges for Vinny's death, an assassination attempt on Mayor Carter Poole, and many other charges.
** In "Above and Beyond," the trope is used in an unusual way. Steve Tomlin, a detective from Danny's precinct, is killed by the leader of a drug organization that he'd been trying to infiltrate after apparently getting outed. In typical fashion Frank firmly promises the widow to bring the killer to justice. They catch the killer at roughly the twenty-minute mark, however, and then the plot turns into a bit of a lurid look at the double life this detective was leading (due to the discovery that someone had emptied Tomlin's locker after his death without authorization). Turned out Tomlin's cover was blown when his wife drunk-dialed a number on the detective's contacts list, thinking it belonged to the other woman, when in fact it was a member of the drug cartel her husband was investigating.
** The two-part season 5 finale concerns the death of Assistant Chief Donald Kent and his wife Maggie in a drive-by shooting carried out by the Warrior Kings gang.
** "Fresh Start" has Erin dealing with the guilt after a criminal she put into the "Fresh Start" program is accused of killing a cop. Some detective work eventually exonerates him, sorta: his rock-solid alibi for the cop's murder is an armed robbery he was committing nearby.
** "Blowback" sees police officer Mark Hayes get shot in what appears to be a retaliation incident for another officer's justified fatal shooting of a teen armed with a knife. Hayes survives, but the police crackdown is ruthless.
* CowboyCop:
** Danny is only too happy to bend the rules in the pursuit of justice.
** Great-Grandpa Henry seems to indicate that he was a CowboyCop in his time. Of course back then there was more "flexibility" in what was allowed anyway.
** Surprisingly, [[ByTheBookCop Frank]] led a unit of cowboy cops some 15 years ago. One of them, Billy Flood, [[DeconstructedTrope snapped under the stress]] and was sent off to the loony bin, later resurfacing [[TragicVillain as a criminal]].
** In "Friends in Need," there's a rookie cop that Danny passes off for Jamie to mentor. He proves very reckless from the get-go when dealing with a perp, causing a bystander to get put in the hospital.
* CrazyJealousGuy:
** In season 2, when Bianca Sanfino hits on Jamie, he suddenly finds himself afoul of her jealous ex ''and'' her mobster brother.
** In "Hall Of Mirrors" anti-terrorism undercover cop Sammy Khan is shot in a drive-by shooting, which appears to be an attempted assassination carried out because of his credentials. As it turns out, he was shot by a guy who believed Sammy was hitting on his arranged marriage fiancée. He believes that just because his and her parents arranged this marriage, that she "belongs" to him.
* CrimeTimeSoap
* CutHimselfShaving: In "Family Ties", a Russian mafiya bombmaker blows off a finger injury. "Slammed it in a door."
* DaChief:
** Frank is constantly directing thousands of cops on city-wide manhunts making him a sort of FourStarBadass DaChief.
** Dino Arbogast is introduced in season 2 as the Chief of OCCB[[note]]Organized Crime Control Bureau, which oversees the Narcotics Division, Auto Crime Division, Gang Division, Firearms Suppression Division, Investigative Support Division, and the Organized Crime Investigation Division[[/note]]. In season 4, he's promoted to Chief of Department after the retirement of Ed Hines, the previous occupant of the position. (The NYPD is so large -- and has so many civilian personnel -- that the Chief of Department is in charge of all sworn officers, but still answers to the Commissioner)
** Sgt. Sidney Gormley functions as one as Danny's supervisor at the 54th Precinct Detective Squad. He is later promoted by Frank to the position of 'Special Assistant to the Commissioner', assuming the duties of the Chief of Department.
* DatingCatwoman: Erin has a habit of this.
* DeathByOriginStory: Joe Reagan.
* DeathSeeker: Sergeant Mabrey in "Unsung Heroes". It starts with an incident with a barricaded suspect in a house. Jamie wants to wait for [[SWATTeam ESU]] and hostage negotiators to show up, but Mabrey storms the house and inadvertently endangers the hostage in subduing the hostage-taker. It's quickly clear to Gormley, once he hears Jamie's side of the story, that Mabrey broke protocol, but he becomes more suspicious when 1) he finds that Mabrey never had Jamie disciplined for disobeying a direct order and 2) uncovers evidence that Mabrey has had five similar incidents in the span of a year, like subduing a emotionally distressed person wielding a knife, jumping onto the subway tracks after an intoxicated passenger who'd fallen off the platform, and responding to an armed robbery outside of his precinct's service area. When confronted about this, Mabrey admits that he is dying from pancreatic cancer. He's trying to get himself killed in the line of duty (with only ten years on the job, his family won't get the health benefits if he dies of natural causes, but they'll collect on his life insurance if he dies in a line of duty incident).
* DetectiveMole:
** In "To Tell the Truth," Linda is kidnapped in an attempt to intimidate Danny into not testifying against a drug lord whom he witnessed executing a subordinate. It becomes clear that there's a mole who leaked information about Danny to the drug lord's network. In the end, it's proven through some digging from Frank's secretary Abigail Baker that the mole bought burner phones for the drug lord, identifying the federal agent who sold Danny out.
** In "Working Girls," Danny and Jackie are assigned to protect a witness scheduled to testify against a Russian mobster who killed an associate's wife, due to Erin's previous star witness (said associate) being killed off by the mobster's henchmen. They hide her in a hotel room, but the room is compromised when Danny realizes that the repairman sent to fix a broken air conditioner is actually a hitman. Danny realizes that there's a leak from the task force. He has Jackie stash the witness at her apartment, while he goes over the files of everyone on the task force to look for the mole. With nothing turning up, he and Gormley hatch a plan: they leak a false address out to the task force, hoping that the mole will react accordingly. Sure enough, he sends two hitmen to the address, and break into an empty apartment occupied by an ESU team. The hitmen quickly rat out the DEA agent who fed them the information.
** Subverted in "Above and Beyond". Steve Tomlin, an undercover detective, is killed after the drug kingpin he's investigating finds out his true identity. When Gormley and Danny go to empty Tomlin's locker, they find it's been emptied and it's suspected that the dealer may have a mole. Turns out there isn't a mole, and Tomlin's locker was emptied early at his request because it was going to be discovered that he was cheating on his wife with another woman, with whom he'd fathered a kid. And it was his wife who accidentally blew his cover, calling a guy in the dealer's crew mistaking him for Tomlin's mistress.
* DiabolicalMastermind: In "The Life We Chose," we have The Phantom, who seeks revenge on Task Force Apache, the network of informants and cops who sold him out.
* DinnerAndAShow: What the family meals sometimes turn into.
* DiplomaticImpunity: In "The One That Got Away" Danny and Baez are frustrated at being unable to press charges against a Moroccan diplomat for abusing his son. Erin manages to get his son removed from him into foster care though. [[spoiler: Near the end, he is {{hoist by his own petard}} after his wife (who he also abused) guns him down in broad daylight. Since she also has diplomatic immunity, they have to let her go.]]
* DirtyCop:
** While Danny's not 'corrupt', many of his actions that are borderline illegal.
** The first season story arc has Jamie doing an off-the-books investigation of the Blue Templar, a secret fraternity of dirty cops. His late brother Joe was on to them and they killed him for it. The first season finale is the Reagan family teaming up to take them down.
** In "Critical Condition," Danny discovers that one of the would-be bank robbers is an ex-cop, Billy Flood.
** In "Framed," Danny is investigating a bookie who has his clients assaulted when they're late paying him. One night, just as Danny's about to get a warrant to raid the bookie's house in search of a black book that will reveal a list of all the clients who owe him money, he's pulled over and busted for drug possession. Danny insists the drugs were planted. Furthermore, Jamie finds that a baker Danny stopped at right beforehand seems to have been intimidated into lying about Danny's whereabouts. As the investigation turns out, an Internal Affairs captain (and one who had previously investigated Danny for a friendly fire incident) was among those who would have been outed as owing money to the bookie when the black book turned up, so he framed up Danny to get him out of the way; even breaking into Danny's house and using Danny's off-duty weapon to kill the bookie.
* DirtyHarriet: One episode has Jackie going undercover to catch a killer with a predilection for webgirls.
* DisappearedDad: Anthony's father has long since passed, but because his mother is afflicted with Alzheimer's and won't be long for the world herself, she sometimes forgets that.
-->'''Anthony''': Dad's not here anymore, remember?
* DonutMessWithACop: Danny gets competitive with another parent (a firefighter) at his son's school.
-->'''Father:''' Cop, huh? [[DeadpanSnarker I bet your dad likes donuts]].\\
'''Sean''': He LOVES donuts!
* DudeWheresMyRespect: When Jamie rescues a baby from a burning building, Sgt. Renzulli takes credit for the rescue to protect the undercover sting that Jamie is engaged in. Played with a little, as Frank gives Jamie the medal he deserves privately later.

[[folder:E-I]]
* EarlyInstallmentWeirdness:
** The set used for Frank's office looks somewhat different compared to later seasons.
** Danny has two different investigative partners before Jennifer Esposito's Jackie Curatola was firmly established as his partner.
** Season 1 is noticeably absent of Frank's Deputy Commissioner of Public Information Garrett Moore, who wasn't introduced until very late in the season. Thus, you have other characters like Frank's Deputy Commissioner doing the duties that Garrett does in season 2 onwards.
** In seasons 1 and 2, Jamie was subject to overreaching season-long plotlines, including the Blue Templar in season 1 and the Sanfino crime family in season 2. That element was dropped for season 3.
* EnemyMine:
** In "Officer Down," when a cop is killed during a diamond robbery carried out by Mafia thieves, the mob actively cooperates with the police to find the shooters.
** Typically, the police and the district attorney's office are shown to have an adversarial relationship. This is especially shown whenever Danny is butting heads with Erin to get a warrant. Yet at the same time, they do work together on occasion.
*** In "Blowback," an officer shoots a knife-wielding teenager. The incident is caught on a body camera the officer was wearing. The grand jury doesn't indict the officer, but around that same time, someone leaks the tape to the Internet. Subsequently, an officer is shot in what appears to be retaliation event. Danny leads the police investigation that looks for the shooter and witnesses who can place him at the scene, while Erin looks for the leaker in the D.A.'s office.
*** In "Drawing Dead," an officer shoots a 14 year old boy that supposedly drew a gun on him, but the gun is nowhere to be found. Erin does a probing of the case and manages to uncover that the boy in question had a prior arrest for illegal possession of a firearm. The officer who shot him also continues to stick to his story. Erin later tells Frank that this sort of matter appears to be one where the police and D.A.'s office need to work together to unravel the truth, given the victim's history, the officer not budging from his original story, and the fact that people in that neighborhood are not known to be very cooperative with police investigations.
** In "Unberable Loss," Reverend Potter, one of Frank's biggest opponents and an outspoken activist, has to put aside his rivalry with the NYPD to get justice for his son.
* EngineeredPublicConfession: The killer in "Hall of Mirrors." One wiretap later, and he's toast.
* EvenEvilHasLovedOnes:
** The theme of the episode "Brothers" is that Erin is trying to bring ruthless gangster Pablo Torres down through his brother Esteban, a straight and clean special education teacher who is being bankrolled by Pablo.
** "Family Ties" has similar themes.
** Benjamin Walker from "Family Business" was one. As Danny explains to Jackie, Walker made his living blowing up bank vaults, but then he fell in love with a woman and she became pregnant. [[{{Retirony}} Then he had one last robbery to carry out before he intended to retire, and that's how Danny caught him]].
* EvenEvilHasStandards: According to Henry, in the good old days even mobsters would help in the hunt for cop killers. For pragmatic reasons, though: Dead cops cause more problems for the Mafia than live ones ever will, since killing cops is a surefire way to set the entire police force on the warpath.
* EvilCannotComprehendGood: While Reverend Potter may not be "evil" per se, he has a very sinister side and often works against the NYPD. In their meetings, it's quite obvious that Potter simply refuses to believe Frank truly puts the people of New York first and isn't a bigot who will always cover police corruption or undue force, thinking Frank must be playing politics when in truth he hates that trend to the core.
* EvilMatriarch:
** The murder in "Family Ties" was a coordinated hit by the bride-to-be's mother. Having married into the Mafiya, she wanted her daughter to [[TheyWereHoldingYouBack have no part of it]].
** A gang banger's mom in "The Life We Chose."
-->'''Ms. Hernandez:''' [''to Danny''] Some cops got shot? Too bad. What you call -- "hazards of the occupation"?
* {{Expy}}: Rev. Potter is essentially a Baptist Louis Farrakhan.
* ExternalCombustion: The fate of a Russian florist who [[HeKnowsTooMuch knew too much]]. He survives, though.
* FakeGuestStar:
** Gregory Jbara as DCPI Garrett Moore. He's in pretty much every episode after the first season, and often gets more screen time than some of the main cast.
** Despite being in basically every episode, Amy Carlson (Linda) and Sami Gayle (Nicky) weren't PromotedToMainTitles until season 5.
* FalseFlagOperation: Reverend Potter had one of his friends call in a fake armed robbery at his church and had his men assault Jamie and Sgt. Renzulli to make it look like the police were racist and attacking his church as revenge for his constant bashing of them.
* FanserviceWithASmile: In her teens, Erin worked as a roller-bunny at a cocktail bar (specifically Roxy's). Frank was apparently aware of it (his mustache twitches in amusement at the memory) but he let it slide.
* AFatherToHisMen : Frank sees himself as one to the 36,000 members of the NYPD rank-and-file. He also can remember exactly how many cops have died in the line of duty since he joined the force, and since he became commissioner.
* FencePainting: In "The Uniform," Jamie is stuck doing this with Sgt. Renzulli to pay for his student loans. Renzulli gamely grabs a brush to help him. "I don't see enough of your mug already?"
* FightingIrish: Danny. Also Henry.
* FoodEnd: Many episodes end with the Reagan family seated around the dinner table.
* FoodSlap: Danny gets a Caesar salad to the face while cornering a perp at his day job -- a short order kitchen.
* FoolishSiblingResponsibleSibling:
** While they're all somewhat mature, amongst Frank's kids, Danny is the foolish while Jamie and Erin are the responsible ones.
** In the Baez family, Maria is the responsible one while her brother Javier is the foolish one.
* FlashbackNightmare: Season 7's premiere opens with Danny having a nightmare about his fatal shooting of Thomas Wilder.
* FramingTheGuiltyParty: Danny once has a gangster he helped put away for a double homicide go free because his then-partner faked blood evidence. Danny scrambles to find new evidence to re-convict, [[spoiler:culminating in the old partner scaring a witness into testifying after Danny can't talk him into it. Danny can't bring himself to use the coerced testimony, so the con goes free.]]
* FreudianTrio: The (living) Reagan siblings.
** Id: Danny, the HotBlooded CowboyCop.
** Superego: Erin, the lawyer who insists on following procedure.
** Ego: Jamie, the Harvard-educated beat cop who gets caught in the middle of Danny and Erin's arguments.
* FriendlyEnemy:
** In "Officer Down," Henry and Happy Jack, a retired mobster; in YeGoodeOldeDays they considered each other as {{Worthy Opponent}}s.
** In "Family Ties," Frank paying a condolence call on a grief-stricken mafioso who [[NotSoDifferent lost his son]].
* FriendlyRivalry: Occasional lighthearted taunting goes on between the NYPD Reagans and a neighboring family of FDNY firefighters. Made more amusing in that Sean's best friend is one of the latter.
* FromTheMouthsOfBabes: What the Reagan children, Nicky in particular, are for.
* TheFundamentalist: The culprits in "Lonely Hearts Club", who are actually the [[spoiler:mother and sibling of one of the victims]], who were interviewed at the start. [[spoiler: Though from the way they acted, the son seemed have talked his mother into it, and he seemed to be in it ForTheEvulz.]]
* GentlemanThief: Jacob Krystal, though [[JustLikeRobinHood he claims to be liberating stolen art]].
* GetOut:
** Guilt-stricken Erin tries to pays a call to her informant's widow, and is sent packing. Rather than feel even guiltier, Erin zeroes in on [[spoiler:the wife's total lack of interest in the case]].
** In "Family Business", Frank visits the mother and sister of a man mistakenly killed by a cop to apologize for her loss. The mother is furious at this and asks if he knows what it's like to lose a son. When he says yes, she asks if he was "shot down in cold blood by your NYPD?" Of course, the answer is again yes.
** In "Front Page News" when Jamie visits the widow of a man he shot in a suicide by cop situation. She becomes furious at the mere suggestion.
** Attempted in "Inside Jobs" by white supremacist radio host Curtis Swint when Frank enters the theatre with a security detail made entirely of non-white cops, led by a large black sergeant.
-->'''Curtis Swint:''' I don't want them or need them. Get out.
-->'''Frank Reagan:''' Well, I'm afraid I can't do that, sir. See the particulars of your contract with the management of this theatre require an NYPD security presence up to and during your broadcast. You're welcome.
* GivingThemTheStrip: Chasing a suspect who dives into a waiting car, Danny gets his raincoat caught in the slamming car door. The suspect and accomplice start driving away, dragging Danny along with them; unable to keep up running for more than a few seconds, Danny struggles out of his coat just in time.
* GoingCommando: Linda in "Night on the Town", revealed when [[DressHitsFloor her dress hits the floor]].
* TheGoodChancellor: Frank Reagan is this in spades, behaving like an [[{{Cincinnatus}} idealized Roman magistrate]]. He is completely incorruptible, loyal to his position, and never plays favorites even when it comes to his own family.
* GoodCopBadCop: Danny and Jackie lampshade this in "The Life We Chose".
* GoodGunsBadGuns: An Uzi-toting biker performing a drive-by in "Hall of Mirrors."
* GoryDiscretionShot: In "The Blue Templar", [[spoiler: Sonny Malevsky]] shoots himself in the head; this is seen via blood spatter on the wall and the shadow of his body hitting he floor.
* GroinAttack: Danny gets grouchy when he has to chase people.
-->'''Joey Sava:''' [[YouWouldntShootMe What're you gonna do?]]\\
'''Danny:''' What am I gonna do? ''This''. [POW]
* GuileHero:
** If Frank can't shoot them himself or put other cops in a position to shoot them, he's perfectly willing to outwit the bad guys instead. He even ran ThePlan on a foreign ambassador whose son was a rapist in "Privilege".
** Both Danny and Erin have a little bit of this in them too.
* HappyBirthdayToYou: In "The ''Bullitt'' Mustang", the Reagans begin to sing the song for Erin's birthday, only for Henry to shut them down by pointing out the copyright law restriction. At the time of the episode's filming in summer 2015, this was true. By the time the episode aired in November 2015 a US district judge ruled that the copyright had lapsed and fallen into the public domain. By air date, the case was still pending with potential appeals. The writers worked it into the story line to illustrate a point in the plot -- in this case as an analogy for a ticket-fixing scandal going on in Jamie's precinct.
* HeManWomanHater: A smug rapist who got off scot-free, and isn't shy about voicing his gender political views. After a heated meeting with Erin, he intones, "She lies. They ''all'' lie."
* HighTurnoverRate: Danny has a high turnover rate for investigative partners. He lampshades it to Gormley after he and Baez are ambushed during the escort of a truck full of seized drugs, which leads to Baez being hospitalized.
** So far, he's had six partners: his first onscreen one is [=DeMarcus=] King (in the pilot). Due to his misconduct getting him busted down to a different squad, and thus received Ava Hotchkiss for a spate of early season 1 episodes. About a quarter of the way through season 1, Hotchkiss departs and is replaced by Jackie Curatola. Curatola is Danny's partner for the rest of season 1, all of season 2, and the first few episodes of season 3.
** In season 3, behind-the-scenes casting issues caused Danny to end up going through ''four'' different partners in the course of a 23 episode season. Curatola had to be written out of the show six episodes into the season in response to Jennifer Esposito being diagnosed with Coeliac disease. This resulted in arcs where Danny works with different partners. He has Curatola for the first four episodes. Then Curatola leaves and is replaced by Kate Lansing, played by Megan Katch. Lansing lasts a few episodes before returning to Internal Affairs after the events of "Framed". After that comes Candice [=McElroy=], played by Megan Boone, for two episodes. Danny then spends "Warriors" directly partnered with Gormley. In "Quid Pro Quo," Danny has no partner, unless you are willing to consider Erin as a sorta-partner. Finally in "Protest Too Much," Danny gets a new partner in the form of Maria Baez, played by Marisa Ramirez, who has been Danny's partner ever since then.
* HelloAttorney: Erin Reagan. Being played by Bridget Moynahan does have its perks. And Charles Rossellini, being played by Bobby Cannavale, counts.
* HollywoodHeartAttack: Poor Henry is hit with one on Thanksgiving. If you thought that was going to stop [[BadassGrandpa him]] from [[{{Determinator}} having dinner with his family]], you're mistaken.
* HollywoodLaw:
** In "To Tell the Truth", Danny and Erin have difficulty convincing an eyewitness to testify against a gangster. To remedy this, the cops leak his location to the underworld, then [[WeWait wait for the gangsters to strike]] before swooping in to "rescue" him.
** In "Critical Condition", Jamie and his new partner, Luisa Sosa, are assigned to "Bingo Bags" -- staking out a park bench and wait for someone to take a bag of stolen goods planted there as bait. Jamie squirms over what he views as "borderline entrapment." It would only qualify as borderline entrapment ''if'' they convinced someone to take the bag--just leaving it out there is completely legal. To be fair, this is Jamie's personal opinion that we're talking about: it may be legal but it may or may not be strictly ''nice''.
** In "Old Wounds", Erin Reagan prosecutes a case where her ex-husband is the defense attorney, with no one raising any concern over just how much conflict of interest there is at hand. This also happens in other episodes, all without any comment.
** In "Protest Too Much", a young couple rob a bank, accidentally shooting a man in the process. Detective Danny Reagan is on the case. As the FBI agents investigating this point out, banks are federally insured, which means any crimes committed during the course of a bank robbery are also federal crimes, even when the shooting was done by an off-duty NYPD cop's gun (he was at the bank and got disarmed by the bank robbers), meaning it should be an exclusive FBI investigation. The NYPD might not even be on the case at all, [[RuleOfDrama but then, of course, there would be no story]]. [[note]]To be fair, the NYPD may not be the lead law enforcement agency on the investigation, although they almost certainly would arrive on scene before the first FBI agent could show up. The role of the NYPD might be to assist in taking witness statements and securing the scene. For the record, "Baggage" had a bank robbery and the FBI never appeared at all even though they should've been there.[[/note]]
** In "Unwritten Rules", Danny gets upset with his prosecutor sister Erin when she won't press charges on a suspect identified as killing a police officer during an armed robbery because the eyewitness, an elderly woman, is shaky on it being him and she doesn't think she'll hold up. While it would still be enough to arrest him, she says to let him go. Later they tell Angelo Reed that there's another witness against him, and offer him a plea deal where he'd only do seven years in prison. Danny then "lets slip" the fact that this witness didn't identify him, and the suspect backs out at once, which is all part of their plan. He's then arrested due to the confession he signed to get the plea deal. While police and prosecutors ''can'' lie to a suspect, this does not apply to the terms of a plea bargain, and self-incriminating statements made on the promise of a deal cannot be used against them if it falls through. Very few people would make plea deals otherwise. Angelo Reed would've walked on this technicality.
** "Justice Served":
*** It's suspected that lawyer Angelo Gallo was shot because he dropped his client, a mob boss, who thought he would tell the police about killing a witness to make the case against him go away because supposedly "attorney-client privilege ends" when their business relationship does. Not even close -- attorney-client privilege applies to ''all'' past criminal activity clients admitted to (unless the lawyer themselves was a party to it). Later on it turns out that Gallo knows the details of the contract killing his client ordered, which he gives to the police. It's not made clear whether he knew about this before or after the crime had occurred, however. Assuming the latter, none of this information could be used against his client.
*** Jamie's partner officer Edie Janko is [[AttemptedRape almost date-raped]] in her apartment. She's reluctant to come forward out of fear she'll appear weak in front of fellow (particularly male) officers. Finally he convinces her to press charges. Rather than hand it off to the Special Victims Unit, whose detectives handle these sorts of crimes, Janko personally arrests the man who attacked her. This is a massive conflict of interest, as she's the one whose complaint they're arresting him on, a fact that any defense attorney would make hay out of (cue RuleOfDrama for this: it's an awesome scene for a TV show but wouldn't happen in real life).
*** Danny is shown as a juror on a murder trial. It would be practically impossible for any police detective to wind up on such a jury, much less one who investigates homicides himself. If nothing else, the likelihood of him knowing likely witnesses would disqualify him. As well, neither side would want a cop on the jury second-guessing or clarifying police procedures for the other jurors -- which is exactly what happens until Danny is kicked off the jury. Then Danny proceeds to take over the case and reinvestigate it, which no police force would likely allow, especially once it had gone to trial.
** In "Custody Battle" Frank is questioned over the fact that his daughter Erin, a prosecutor, was assigned to review the death of a suspect in the custody of his department. Frank is rightly asked if she can be objective, considering that a negative finding will reflect poorly on him as police commissioner. Like the examples above with Erin prosecuting cases where her ex-husband is the defense attorney, it's a conflict of interest to investigate matters than even tangentially have to do with a close relative, and she'd have to recuse herself.
*** This also applies to how Danny often goes to Erin when he needs search warrants. As they are siblings, the same conflict of interest rule may apply here. On the other hand, if Erin doesn't have a choice on which cases are passed to her, there may not be conflict of interest if she's prosecuting a case that Danny investigated.
*** A big example of that is "Loose Lips". Erin tries to get Russell Price indicted for beating his girlfriend to death and then trying to kill Jamie by lobbing a Molotov cocktail into his patrol car. There's a massive conflict of interest for an assistant district attorney to prosecute someone who threatened or committed a crime against a friend or relative of theirs (that is, Jamie). Admittedly, the judge at the hearing ''does'' point out that the fact that both of Erin's brothers are involved in the case (Danny as lead investigator, Jamie as a victim) could lead to Erin showing perceived bias against the accused, but Erin would have had to have someone else prosecute Price.
** Likewise, someone with Danny Reagan's record of complaints for use of force would probably not be allowed to work with the public. Even with his father being the active commissioner, Danny's actions could easily become a liability for the NYPD if someone sues him for emotional distress/police brutality/whatever.
** "Backstabbers" sees JurisdictionFriction going on between the NYPD and United States Marshals Service over the manhunt for two prison escapees. While it's never said whether the prison the two escapees broke out of was a federal prison, it's also never said if the prison in question was a state correctional facility. If the latter, the Marshals would have no involvement in the case because they work for the federal government; the US Marshals Service has no responsibility or authority over escapees from state prisons, unless the escapee crossed state lines, which the two escapees haven't.
** In "All the News That's Fit to Click", an anti-cop criminal shoots Lorenzo Colt, a reporter who happens to be dressed in an NYPD-issue windbreaker, while he's doing a ridealong with Jamie and Edie. The suspect, Michael Hicks, who has a history of violence against cops, is arrested. Colt is brought in to identify the suspect in a lineup, he refuses to identify Hicks and is let go, as is Hicks. In reality, if a victim refuses to cooperate such as refusing to identify a suspect, the state can still prosecute a suspected offender based upon other evidence. Which, for the record, the police already had, as voice recognition had proven with 95% certainty that Hicks made the 911 call that lured Colt and the officers he was riding with into an ambush.
*** From the same episode, Frank surmises (and Danny and others buy into) the suspect thought they were shooting a police officer due to the fact that Colt was wearing an NYPD windbreaker when he was shot. Now consider Hicks' hatred of cops. Most people in real life know that police officers rarely ever sit in the backseat of patrol cars. Frank and Danny use the term "cop killer" even though the victim survived with fairly minor injuries[[note]]three rounds were absorbed by his bulletproof vest and one lightly grazed his neck; he was also conscious and on the phone with his publisher within a couple hours of the shooting[[/note]]. Based upon the known evidence at the time, it should have been apparent and assumed that Colt was being targeted specifically and not mistaken for a cop -- since if the shooter's intent was to kill the officers, he probably would have shot them while they were still on the street and distracted by the reporter. Erin was the only one to properly assess the situation in that no one was killed and it was not a cop involved but a reporter.
** In "Occupational Hazards":
*** When arresting a woman that's running a fraudulent charity that's been using the NYPD emblem, Frank tells her that three other cities have arrest warrants for her and that New York will have to wait. While such a scenario could happen in real life, it'd be more likely to be the case if she was wanted for more serious charges in those other cities. Upon taking her into custody, the state of New York would have the choice of trying her there first or allowing her to be extradited.
*** Twice do characters break police protocol. For instance, when Erin was being followed by the bikers, protocol would be to call for a Radio Mobile Patrol (RMP) car to assist, rather than drive to Danny's precinct. Likewise, when the bomb suspect was at the union meeting, protocol would be to have the sector RMP car respond to assist as they would be far closer, or alternately, to call ESU in.
** In "Drawing Dead," when discussing Marcus Greene, a 14-year-old boy shot dead by a police officer, Erin informs a companion from the DA's office that the boy had a juvenile record for gun possession. The companion asks, "Aren't those usually sealed?" to which Erin replies by implying that she got them by calling in a favor. Juvenile records are sealed to the public but remain available to prosecutors, and any expungement of a juvenile record (the only means by which the record would be permanently unavailable even to prosecutors) is unlikely to occur until the person reaches age 18, and certainly not within two years after the original delinquency charge.
** In "Family Ties," Chelsea Cole, a banker who has handled kickbacks for corrupt deputy mayor Randy St. Clair says, "Where our clients' money comes from is not our concern." Actually, it is. By law, American banks are required to notify law enforcement when they find any evidence that their clients are involved in money laundering or any form of criminal activity. It's justified because as it turns out, she was the lover of the deputy mayor's aide, and they were both accomplices to St. Clair's corruption.
** In "The Road to Hell":
*** Nicky and her friends are pulled over while she's doing designated driver duty for them. An officer finds a controlled substance in the backseat[[note]]the reason he did so is because Nicky's passengers mouthed off to the cops. Since the cops were led to assume that they were hiding something, he looked them over and found the drugs[[/note]]. When they don't immediately tell him who the owner is, they all get arrested. While a field test of the drugs is done, it's done AFTER the arrest. In reality, it's required to be done BEFORE the arrest. After that, the baggie has to be tested for prints, and then the possession is construed to be where it was located, in this situation the girl behind the driver.
*** Not to mention that arresting everyone in the car -- especially before any presumptive field test was performed -- could be construed by a lawyer as a bad arrest. Proper procedure with any criminal investigation with multiple suspects in the same room/vehicle is to split up the occupants and question them, and only after Mirandizing them (and we see a more proper version of this in the same episode as Danny and Baez deal with four women who are confessing to the same murder). An immediate arrest would not be necessary if no physical or constructive possession could readily be proved. The evidence could have been vouchered and tested for latent prints.
*** A troubled boy has been stealing money from the church that Frank goes to. Frank talks to the pastor, and learns that the boy took over $3500 from the poor box. But the vic also says that he doesn't want to press charges against the boy. The theft of $3500 is enough to qualify for grand larceny, which is a more severe offense, and depending on the circumstances, means the D.A.'s office may be required to press charges, regardless of the victim's wishes.
** In "New Rules" and "The Art of War", two things:
*** Erin is put in charge of handling warrants for Danny's case, the murder of a deputy chief and his wife. As said before, since she and Danny are siblings, she would have to recuse herself from such a case because of the conflict of interest at hand. Furthermore, they'd be allowed to detain Mario Hunt for up to 48 hours before they'd have to release him.
*** Such a case would probably be handled by the NYPD Gang Division rather than the Major Cases Unit.
*** In "The Art of War," Danny's lead witness is killed in the hospital. In the course of the shooting, Linda is hit by a few stray bullets and hospitalized as a result. Danny continues to be assigned to the investigation. In real life, he would be required to pass the case off to someone else, again because of conflict of interest (his wife is now among the collateral victims in the case, and such a thing could cloud his judgment). He wouldn't even be allowed to stand in the same room as the shooter, out of reasonable fear that he might take his anger out on the shooter, which could jeopardize the case.
** In "Fresh Start," a man who went through the Fresh Start program has been arrested and accused of shooting a police officer. Yet the officers seem somewhat incompetent in that they don't bother to test the arrested man's hands for gunpowder residue.
*** Furthermore, where were all of the much-vaunted NYPD detectives, who SHOULD have been the ones to investigate the crime? As soon as it became known that the arrested guy did NOT shoot the cop, it's the responsibility of the ''police'', not the D.A.'s office, to find the true shooter. They didn't even consult with anyone at the NYPD. (Yes Anthony is technically from the NYPD, but it's not the same thing.)
** In "Manhattan Queens", someone is doing cannonball speed-runs around the boroughs and taunting the NYPD while doing so. Abigail Baker, Frank's secretary, says she's identified the person as Suffolk County deputy chief Salvatore [=DeLuca=], who's been repeatedly asking her out despite her turning him down. Her evidence is, in her words, the hundreds of voice messages he's left for her, the juiciest of which she says she's saved in case his gestures escalate to harassment. Most police forces, in particular the NYPD, would probably not consider that harassment, but ''stalking''. Also, for this to be happening against the Commissioner's secretary without him noticing is a bit suspicious. Furthermore, that Baker could make a positive ID on the voice should've been enough to at least have [=DeLuca=] brought in for questioning.
** In "Help Me, Help You," Erin files a complaint against her mentor, a judge who's been imposing harsh sentences on defendants tried in his courtroom ever since his wife was killed in a DWI incident (which does get said judge to realize what Erin's been trying to tell him face-to-face -- that he's been letting his grief cloud his judgment). While Erin did the right thing, and anyone can file a complaint against a judge, it usually involves people directly connected with a case. In the first scenario with the first-time offender who got the maximum sentence, the defense attorney certainly should've filed a complaint, as well as made an appeal for an Eighth Amendment violation (cruel and unusual punishment) and prevailed. Same goes for the other scenario, where evidence got tossed -- the defense attorney would've appealed.
** In "Through the Looking Glass," a reporter gets an anonymous interview with the man who set a hobo on fire in Brooklyn's Brownsville neighborhood. When told by Frank to give up the killer, she refuses, claiming she's protected by the First Amendment, which it certainly does not when other peoples' lives might be at stake.
** In "Blast from the Past," an officer named Thomas Scully is up for promotion to Sergeant. Thing is, he was acquitted in the death of a Muslim teenager [[ShootHimHeHasAWallet who was shot 61 times while reaching for his wallet in a dark apartment]]. It's mentioned that the other three officers who were with Scully were also acquitted and resigned after the trial. In real life, it'd be highly unlikely he'd keep his job, since the NYPD, like every other police department, has really strict conduct guidelines. Which means officers can be punished (up to and including loss of job) for misconduct regardless of any criminal trial.[[note]]Which was shown in a season 4 episode where an officer used an illegal chokehold on a suspect in a precinct bathroom -- he wasn't indicted, but he lost his job because he broke protocol.[[/note]] Absent something like a political connection, he'd have been let go, ''and'' he would have been blacklisted by the department. He'd be placed under a microscope and would be written up for any number of minor violations. Long story short, he'd be run out of the NYPD and probably blackballed at every other police force.
*** Not to mention that by singling out Officer Scully and subjecting him to added scrutiny beyond the promotional process, Frank would open the NYPD to civil action. Indirectly denying him the promotion or making punitive conditions prior to awarding it would practically make it a guarantee.
** From what's shown, it seems that Mayor Carter Poole was elected into office in 2011, and was successfully reelected in 2015, with this implying that mayoral elections in New York City come in the off-year before a Presidential election cycle. In reality, the mayoral election cycle in New York City happens during the off-year after a Presidential election cycle.
** In "The Greater Good," Danny is being hauled before a grand jury over his fatal shooting of Thomas Wilder. Frank refers to Danny's issue as a case of DoubleJeopardy. But Danny was never brought to trial, so double jeopardy would not apply. Furthermore, during the grand jury hearings, Nicky is on the stand and asked what Danny said to Wilder on the other end of the phone conversations. She caves in 2 seconds and not only tells them verbatim, but says it word for word in dramatic fashion. Thing is, her mom is the ADA and was there when Wilder died, so Erin should have prepped her beforehand.
** In "Family Business", Jackie Curatola is trying to locate Danny, abducted by Benjamin Walker. When the cab dispatcher is uncooperative, she threatens him at gunpoint into giving up the location of the cab Danny is in. The reason why she doesn't face any consequences for this is due to the "exigent circumstances" rule (someone's life is in grave danger), which only applies to conducting searches without warrants, not making threats against people.
** In "Love Lost", a suspects confession is excluded from evidence because he hadn't been read his MirandaRights before giving. However, he gave the confession spontaneously, so it would be admissible.
* HollywoodTactics: In-story. During their brief loan to the Movie and TV Unit in "Price of Justice," Edie and Jamie find that the police consultant is making the show's characters do things that would be stupid for a real cop to do. One is having the leads draw their guns on the perp from both sides, which [[IJustShotMarvinInTheFace means both leads are in each others' line of fire]]. Later, one of the leads asks Edie and Jamie about the part in the script where the leads charge into a burning meth-den and arrest the perps. Edie and Jamie point out that cops only do this in real life if hostages or bystanders were in imminent danger. Not helping is that the police consultant is a fraud.
* HoneyTrap: The victim in "Family Ties" was supposed to be photographed kissing a hired blonde. The [[spoiler:mother of the bride]] decided to cut out the middleman and shoot him instead.
* HostageSituation:
** A trio of {{Bank Robber|y}}s get more than they bargained for in "Critical Condition." Danny gets the obligatory reference to ''Film/DogDayAfternoon.''
** "In the Box" sees Baez get taken hostage in the precinct interrogation room by an estranged husband that she and Danny had served a restraining order on. Danny works negotiations with ESU and the precinct commanders from outside. Erin gets involved, having to help persuade the guy's ex-wife to help resolve the situation so that everyone walks out alive.
* HotBlooded: Danny.
* HowUnscientific: The "Leap of Faith" episode has both the identity of the murderer and an important bit of evidence revealed through the daughter of the VictimOfTheWeek getting messages from {{God}} in an otherwise realistic CopShow.
* HypocriticalHumor: Despite Henry telling Frank to start using an automatic, he's shown with a revolver in "Dedication".
* IdiosyncraticEpisodeNaming: Each of the episodes takes its name from some sort of common theme going on in each of the different plotlines. For example:
** "Under the Gun" in season 5 has three plotlines in which a firearm is involved in some form. Danny and Baez are investigating drive-by shootings by a guy on a motorcycle, Erin is dealing with a gang murder trial that's in jeopardy because the murder weapon has been switched out, and Linda contemplates buying a gun to arm herself after getting mugged.
** In "Sins of the Father," Danny and Baez investigate murders that were committed by the parents of a porn star who committed suicide, while Frank deals with the fact that the father of a recently promoted detective is a man who killed a police officer in front of Henry back in the 1970s, and Jamie and Edie are handling a hit-and-run incident where a father turns out to have taken the fall for his son.
** In "Power of the Press," the common theme is the media: Frank is dealing with the case of a cop participating in a bodycam pilot program who got into a scuffle with a criminal he was detaining. Danny and Baez meanwhile are protecting a material witness who's been kicked out of WITSEC on a technicality, and get him back into the program by using the influence of a reporter who has been poking around the case looking for the scoop. And Erin, upon finding out that the dean of students at a college hindered the investigation into the rape of Erin's schoolmate's daughter, makes clear when arresting the dean that she's going to make sure the media and the public see what passes for "justice" on the campus.
** In "Loose Lips," a domestically abused woman is beaten to death after her boyfriend thinks she told Jamie about him.[[note]]Jamie had spotted her on a park bench, badly bruised, while on his morning jog, and handed her his business card, but she'd disappeared while he was flagging down an RMP.[[/note]] Nicky gets denied admission to Rutgers due to insensitive tweets she made about one of her teachers, while Henry gets in trouble when he's caught on camera drunkenly mouthing off to a colleague about some aggressive police tactics he'd like to reintroduce.
* IHaveYourWife:
** In "My Funny Valentine," a teenager fakes her kidnapping to spite her wealthy dad. The plan goes awry when a co-conspirator decides to [[CryingWolf ransom her for real]].
** "In the Life We Chose", Phantom, a recently released drug kingpin who just killed an undercover detective and critically wounded another, takes a former Task Force Apache snitch's family hostage to get the man to show himself.
** In "To Tell the Truth," while on a late night shopping run, Danny witnesses a drug kingpin named Raymundo Salazar personally execute the brother of an associate who's been skimming from him. After some work, he and Jackie manage to arrest Salazar without incident, despite knowing that Salazar has a history of skating by threatening or killing off witnesses. Sure enough, some of Salazar's henchmen (aided by an inside mole in the investigation) kidnap Linda in an attempt to buy Danny's silence. Danny, Jackie, and Jamie work to locate Linda while Frank and Erin track down the mole.
** In "Under the Gun," Erin is prosecuting Winslow Martin, a gangbanger who executed a man named Thomas Dunn in cold blood. The case is put in jeopardy when it becomes apparent that the murder weapon that the investigating detective vouchered has been switched out with an identical one prior to being presented at the trial. As it turns out, Erin's new intern Olivia was behind it -- her brother runs with Winslow Martin's gang and they have taken him hostage to threaten her into tampering with the evidence to get Winslow acquitted.
* IJustShotMarvinInTheFace: {{Invoked|Trope}}. In "This Way Out" some of the Los Lordes gangbangers trick a mentally challenged kid from the Bitterman Projects into shooting Mayor Carter Poole at a townhall meeting by telling the kid it'll be a hilarious joke.
* ILoveYouBecauseICantControlYou: Thief extraordinaire Jacob admits he's pursuing Erin because he "loves a challenge."
* ImpersonatingAnOfficer:
** In "Down the Rabbit Hole," serial killer Thomas Wilder kidnaps Nicky while dressing up as a police officer.
** In "The Price of Justice", Jamie and Edie are on loan to the NYPD Movie and TV Unit[[note]]New York City is such a popular filming location that that NYPD has a dedicated unit that helps out with movie and television productions, from creating fake crime scenes to security and consultation for the actors[[/note]] for the filming of a ''Series/RizzoliAndIsles'' esque-cop show. A former cop is a special consultant hired to handle the "research", but it seems he does not grasp the reality of stuff (like having female cops in heels, a big no-no in a foot chase). The actresses ask Jamie and Eddie for advice on a scene. The consultant is outraged and threatens to report them to "their commanders", which confuses Eddie because in the NYPD, the terminology is "commanding officer." After a few more arguments where the man yells he's the expert, Jamie and Eddie get a detective to do some digging, and find that this "consultant" has never worked for the NYPD, and his only law enforcement experience is as a mall security guard in New Jersey. The consultant is fired in the end, though not for the fraud, but for sexual harassment.
* IncorruptiblePurePureness: Jamie has shades of this.
* InformedAttribute: In "Black and Blue", Frank blackmails the Mayor, insults an activist preacher to his face, and leaks a taped confession to the press. At the end, Frank's lawyer praises him for his political savvy (!) and urges to run for Mayor.
* InsanityDefense: In "Open Secrets," Erin prosecutes a woman with bipolar disorder who ran down and killed the superintendent of her building with her car. This is an open-and-shut legitimate case of the defense since the woman has been in and out of mental institutions. Erin's only problem is that there's a very arrogant expert witness who as it turns out has gotten sloppy by failing to properly analyze the defendant's medical records and not doing a long enough session to get an accurate picture of her disorder.
* InsultToRocks:
** In "Rush to Judgment," civil rights attorney Gerry Guerrero compares the NYPD to TheMafia. At the denouement he tells Frank, "I should be apologizing to the members of the Columbo and the Gambino family for comparing them to you."
** In "Knockout Game," Frank and his chiefs are discussing how to deal with the recent spate of gangs giving haymakers to random pedestrians after Danny catches the latest case, a pregnant woman who ended up miscarrying. For which Frank comments, "Look this kind of stupid, random brutality is giving regular street crime a bad name. Let's appeal to the sense of pride in the professional criminal."
* InternalAffairs: The NYPD's Internal Affairs Bureau exists, and it seriously needs to tighten up its recruiting standards. We've seen two recurring-role investigators who have been revealed to have been crooked: Season 1's Lieutenant Alex Bello is at first seen to be hard-nosed-but-professional ... but is later revealed to be a member of the ultra-corrupt Blue Templar fraternity. Captain Derek Elwood is introduced in Season 2, again tough-but-fair ... but who is also later revealed to be crooked and framed Danny for drug possession and murder in Season 3 in an attempt to cover his gambling habit. On the other hand we have Detective Kate Lansing, Danny's first interim partner between Jackie leaving and Baez coming in. She started in IA and then went back there after a few episodes.
* IntroductionByHookup: Non-sexual example. Erin loses a bet with Linda and has to take a speed-dating session. One of the guys at the session turns out to be Robert [=McCoy=], her opposite number in the Case of the Week. [[spoiler:End of the episode, he asks her out to dinner and she accepts.]]
* ItRunsInTheFamily: Nicky browbeating Erin into letting her stay out until 11:00 (to quote Henry, "[[WhenIWasYourAge I was out on an aircraft carrier in the Pacific]] at her age!"). Frank wryly observes that she "made a very convincing argument."
* ItsPersonal: In general, any episode where a cop dies.
** In "Officer Down", a cop dies in the line of duty. It becomes personal for every single cop in New York.
** "Hall of Mirrors": an undercover cop is shot.
** And of course, "Dedication", in which Frank is shot.
** Frank considers the death of ''any'' cop a personal grievance ("The Life We Chose").
** "Silver Star" is personal for both Frank and Danny, as both were Marine vets, and so was the victim.
** The season 5 two-part finale concerns the death of Deputy Chief Donald Kent and his wife in a gangland hit.
** The case of Raymond, a police dog accused of biting a boy in "Bad Blood", is personal for Frank, who was a canine handler in the '80s, but transferred out after his dog Greta was shot dead by a burglar.
** The case of serial killer Thomas Wilder over three season 6 episodes, who makes it personal after Danny calls him a coward on TV, and moreso by abducting Nicky.
* ItsQuietTooQuiet: In "The Bitter End," Jamie and Vinny Cruz pursue a purse snatcher into the playground of the Bitterman Housing Projects, shortly after the Los Lordes criminal organization (who practically control the Projects) has declared war on the NYPD. Upon entering the Projects, Jamie suddenly notices that the area is completely deserted, something highly unlikely in this neighborhood in the middle of the day....[[FiveSecondForeshadowing unless they're being set up for an ambush]]. A split second later, a gunman on the rooftop opens fire on them. Vinny is killed while Jamie barely gets out alive.
* IvyLeagueForEveryone:
** Jamie is a Harvard boy. Deconstructed in that it's mentioned a couple times he's having money problems due to his student loans. To the point that at one point, he has to take up a second job with Renzulli as a fence-painter.
** Erin is a Columbia graduate, and in Season 6, her daughter Nicky is following in her footsteps.
* IWillShowYouX: Frank on the city council's attempts to cut the NYPD's budget:
--> "Hey, I got a good 'shared sacrifice.' How about we outsource 911 to Bangalore?"
[[/folder]]

[[folder:J-O]]
* JackBauerInterrogationTechnique: Danny can get a ''little'' rough with criminals. Just ask the guy whose head got shoved in a toilet in the pilot episode.
* JerkWithAHeartOfGold:
** In "Framed," Henry hires Erin's ex-husband on the sly to be an attorney for Danny when he was framed by [[spoiler:a crooked InternalAffairs agent]], he bills for it... totaling all of $1.
** Danny has shown to be this trope. While he can be hard on criminals and be borderline DirtyCop, he has a heart of gold when it comes to his immediate family.
* {{Joisey}}: Inspector General Kelly Peterson from Season 4 is originally from [[{{UsefulNotes/NewJersey}} Newark]], New Jersey, and previously served as the Essex County Prosecutor before accepting the newly-created position of NYPD Inspector General.
* JurisdictionFriction:
** The [[InterserviceRivalry FBI/NYPD rivalry]] so often seen in NewYorkCityCops series.
*** "Protest Too Much" has Danny grumping that the FBI is involved in his latest case due to the murder happening in the course of a bank heist ([[HollywoodLaw in Real Life]] it would be FBI jurisdiction automatically, as banks are federally insured, including all crimes committed during a bank robbery; the NYPD though could liaise through their Central Robbery Division).
*** In "Down the Rabbit Hole", the FBI preemptively releases a press release about serial killer Thomas Wilder when some of his bodies turn up, without conversing with the NYPD first. Of course, the FBI does have jurisdiction since Wilder is wanted for crimes in multiple states, but it still is this for their failure to share information with the NYPD. Danny also clashes with one of the FBI investigators he's forced to work with.
** Though averted on a few other occasions --
*** In "Officer Down," it's mentioned that the FBI is on-board to help out with the death of an officer in a jewelry robbery.
*** And in "Bad Company," when Danny and Baez are investigating the abduction of a woman believed to have been taken in by a sex trafficking ring. They recruit Janko to be their infiltrator, and then join up with the FBI when they learn the FBI is also working the case.
** The episode "With Friends Like These" has Frank dealing with tensions between the FDNY and NYPD. It starts when a group of Emergency Service Unit officers and firefighters being treated in Linda's emergency room get into a brawl after throwing insults at each other. Things get to a head later on when an officer is hospitalized from injuries sustained in a gunfight caused by a botched drug raid, the result of firefighters wanting to engage a blaze that the police believed was set by the drug dealers to torch evidence that they were trying to obtain.
** "To Protect and Serve": Danny is investigating the murder of a father who was gunned down in front of his son. A description of the gunman from the son leads Danny and Baez to identify the shooter as a man who happens to be feeding information to the Department of Homeland Security about a drug operation that may be involved with terror cells. The DHS refuse to let their suspect get taken off the streets for the murder. At Erin's suggestion, Danny and Baez work around the stonewalling DHS by tailing the suspect's handler to identify the guy's hideout, then takes an ESU team in to capture the guy.
* JustTrainWrong: The opening to "Samaritan" is supposed to take place on a 2 train on the IRT Nostrand Avenue Line, seeing how the crime scene investigation has the train stopped at Newkirk Avenue station on that line. However, the train shown is clearly comprised of R160 cars used on the subway's BMT and IND divisions, which are larger and wider than the R142 cars used by the 2 train. Furthermore, when the train doors are closing, the door chime is that used on subway cars built in the 1970s and 1980s as opposed to the electronic chime used on the R142 and R160 cars. Additionally, the station signs on the entrances designate the station as only being serviced by the 2 train when in reality the station is also serviced on weekdays by the 5 train (and is noted as such on the real station signs).[[note]]The only station solely serviced at any time by the 2 train is its northern terminus of Wakefield -- 241st Street. Every other station is shared with the 5 train and/or the 3 train.[[/note]] The station where the gang leader is arrested also appears to be Broad Street station on the BMT Nassau Street Line being passed off for Third Avenue -- 149th Street on the IRT White Plains Road Line.[[note]]This may be justified from a production standpoint as at the time the episode was filmed, Broad Street was closed on weekends, allowing them to shoot footage without interrupting regular service.[[/note]]
* JustifiedCriminal:
** Billy Flood's motive in "Critical Condition" for robbing the bank: [[spoiler:paying for his 8-year old daughter's heart transplant]].
** Jacob Krystal claims that his motive for art theft is that he returns works stolen by the Nazis during UsefulNotes/WorldWarII to their rightful owners or their heirs.
** In "Baggage", a group of former Army veterans rob a bank [[spoiler:to pay for treatments for a comrade of theirs who lost his legs to an IED and suffers from traumatic brain injuries]].
* KarmaHoudini: One episode in season 7 features a very smug pretty boy who gets off on beating his girlfriend and claims she wanted to play rough, when he actually handcuffed her to the bed and subjected her to torture for his own pleasure, not knowing he was a depraved and predatory sex fiend. Danny can't get him convicted for assault and sexual abuse because the man lawyers up and his lawyer tries to pin the blame on the girlfriend [[LoopholeAbuse because she consented to him having his way with her.]] The man and his lawyer also know that the woman's name will be dragged through the mud in court over this debacle, and this alone is enough to give her cold feet and make her drop the charges. Worse, when Danny and Baez try to set him up to make him beat his girlfriend on camera, the man is too sly to fool and mocks them openly for trying this. Danny, however, refuses to let the man get off so easily and publicly outs him as a woman-beater, warning him that even though ''he'' failed to bring him to justice, there are ''[[HolyShitQuotient 30,000]]'' cops in New York City and now ''[[AwakenTheSleepingGiant all]]'' of them will be [[ParanoiaFuel watching him.]]
%%* KnightInShiningArmor: Jamie.
%%* KnightInSourArmor: Danny.
* LawEnforcementInc: In season 2, a shady private security outfit tries approaching Henry with a job offer. So far, he's turned them down.
* LetMeTellYouAStory: [insert Grandpa Henry moment of badassery here]
* LikeFatherLikeSon: In season 7's premiere, the widow of a cop killed in the line of duty comes to Frank asking him to fail her son out of the police academy, not wanting to risk losing him as well. Thing is, said cadet is one of the best in his class, and despite Frank's best efforts, he can't find anything that would disqualify him.
* LikeRealityUnlessNoted:
** As far as the NYPD is concerned since 9/11 and the UsefulNotes/WarOnTerror still happened in the show's universe. The actual NYPD Police Commissioner during the first four seasons of the series was two time appointee Commissioner Raymond Kelly. In 2014, during the show's fifth season, Mayor Bill de Blasio appointed former NYPD Commissioner Bill Bratton to the position[[note]]Bratton had been commissioner from 1994 to 1996; between his two tenures as NYPD Commissioner, he served as Chief of the UsefulNotes/LosAngeles Police Department[[/note]]. Then in 2016, Bratton retired and his Chief of Department James P. O'Neill became the current Commissioner. Henry Reagan's tenure of office, stated to have been sometime in the 1970s, would most likely have occurred during the tenure of Commissioner Patrick V. Murphy.
** A newspaper clipping in "Re-Do" suggests that the mayoral history of New York City was the same through at least Rudy Giuliani. Frank Russo is implied to have taken office then, and held the office until Carter Poole was elected. A telling hint is in the season 3 finale when Danny is interrogating a Los Lordes gangbanger after Mayor Poole gets shot by a Bitterman kid on the gang's orders -- he calls Poole "the second black mayor in New York City," meaning that David Dinkins still became mayor in this timeline.
** Hurricane Sandy still happened in this timeline. A friend of Danny's who lived in the Rockaways is shown to have been impacted by the hurricane. In "Back in the Day," Erin finds that one of her investigators was killed because he was looking into a case of corruption related to Hurricane Sandy rebuilding contracts.
* LoanShark: Sgt. Renzulli gets in deep from betting on horses. Frank bails him out, with the explicit proviso that it's a one-time only offer.
* LookBothWays: Happens ''twice'' to a Croatian gangster, who's fleeing after the police interrupt his attempt to trade a kidnapped girl for some fellow gang members. Not watching for traffic, he gets bounced off a taxi's fender as he steps off the curb, losing his gun. His pursuer, Danny, draws and demands his surrender, but he [[TooDumbToLive steps onto the road without looking]] ''again'', sneering that Danny won't shoot him in the back ... and gets hit head-on by a delivery truck.
-->'''Danny:''' [[BondOneLiner Yeah, he forgot to look both ways]].
* LoopholeAbuse:
** In "The Job", Danny nails a suspect by casing his house until the garbage truck arrives, since, after all, trash left outside on the street is technically not on private property, and thus can be searched without a warrant.
** In the season 5 two-part finale, Deputy Chief Donald Kent and his wife are gunned down in a gangland hit. It's proven that the hit was carried out on the orders of Clinton Wallace, the leader of the Warrior Kings gang, who is doing life at Rikers for other crimes. Frank visits Rikers and arrests Wallace for conspiracy to murder Kent, Kent's wife, and Hector, a witness to the Kents' death, and the attempted murder of Linda (who was hit by a collateral bullet during the assassination of Hector). Wallace laughs at the charges as he's already serving life, but Frank then explains that a search of Kent's possessions revealed that he took an oath with the United States Marshals Service, which allowed him to work with the DEA. The oath technically made Kent a federal law enforcement agent. And while New York state law doesn't have the death penalty, federal law ''does'', so Wallace will be extradited to Terre Haute, Indiana to stand trial for Kent's death, which also removes his ability to give orders to his gang.
** In "To Protect and Serve," Danny and Baez suspect that a career felon named Raoul Delgado is responsible for gunning down a man in broad daylight (in front of the man's son). However, Delgado has apparently been feeding information to the Department of Homeland Security about a drug operation that is collaborating with terrorist organizations. DHS members separately approach Frank and Danny telling them to back off on Delgado. Danny approaches Erin trying to see if she can get a line that breaks through the stonewalling DHS. She tells him she can't ... but then she says that there ain't no rule saying that Danny can't just tail Delgado's handler. Danny does just that and is then able to take an ESU team to apprehend Delgado.
** In "Excessive Force," Gormley passionately stands up for his squad while Danny is being investigated for an alleged case of excessive force. Frank is impressed enough that he decides that Gormley should be his liaison with the rank and file cops. However, Gormley is too low in ranks to be eligible for Chief of Department,[[note]]who must be a Captain or higher; Gormley is just a Sergeant,[[/note]] so Frank creates a new job post of "Special Assistant to the Commissioner" and gives Gormley the duties of the Chief of Department.
* LoveCannotOvercome:
** Jamie's girlfriend left him because she couldn't stand loving a cop with ChronicHeroSyndrome.
** Linda seems to have finally had enough when her son witnesses a shooting.
-->"I'm tired of playing second fiddle to the NYPD."
* TheMafia: Season 2 has several subplots where Jamie is sent on investigations into the Sanfino crime syndicate. Other episodes occasionally involve organized crime factions.
* TheMafiya: "Family Ties" deals with the murder of the son of the head of the Russian mob in Brighton Beach at his own engagement party. [[spoiler:The mother of the bride is the killer: she didn't want her daughter trapped in the mob the way she was.]]
* TheMainCharactersDoEverything: More like "The Main Characters All Do the Same Thing". Generally speaking many cases are found by Jamie and his partner, investigated by Danny and his partner, and prosecuted by Erin and her party.
* MakeItLookLikeAnAccident:
** In "Cellar Boy," the brakes on Jamie's car are cut to try and get him killed in an accident.
** Perp not talking, huh? Hey, Danny notices a very nice looking katana on the wall:
--->'''Danny:''' Okay. Here's how my testimony's gonna go. "The suspect grabbed a sword down from the wall, I ordered him to drop the sword, he failed to comply, [[BlahBlahBlah bladda bladda bladda]], I feared for my life, so no I had ''no choice'' but to fire my service weapon striking him [[CutHisHeartOutWithASpoon several times in the chest and face]]."
* MalcolmXerox: Rev. Darnell Potter is a fairly transparent copy of the Rev. Al Sharpton. Not only is he a demagogue, an accessory to murder, a crook, a hatemonger and a liar, he's waging a motiveless war on the NYPD to boot. Later he gets ported to being a [[NoCelebritiesWereHarmed not-Black Lives Matter]] figurehead.
* ManlyTears: Frank gets choked up while recounting 9/11 in "The Job."
* ManOnFire:
** In "To Tell the Truth," after Linda is kidnapped by associates of a drug kingpin that Danny witnessed committing a murder, Danny gets notified that a body has been found in a torched car. Fearing that it's Linda's body, he rushes to the scene, where Frank quickly tells him it's not Linda. It is, however, the body of the girlfriend who gave up said kingpin to Danny and Jackie.
** In "Through the Looking Glass", a group of gangbangers in the Brownsville neighborhood of Brooklyn set a homeless guy named Benjamin Wilson on fire. Reporter Anne Farrell uses the incident to criticize the NYPD's patrolling of neighborhoods like Brownsville. Things get complicated when Farrell scores an interview with the murder suspect, who says (with face and voice altered) that the murder was part of a gang initiation, and that she can be certain it will happen again. Frank tries to get Farrell to give up the name of the killer, but she claims First Amendment protection. Erin gets a judge to compel Farrell to give up the information in order to prevent a future violent crime from being committed. Farrell refuses to testify and goes to jail for contempt of court, where Frank visits her. He says he has nothing to do with her being in jail, then convinces her that while she may not agree with Frank about the policing in Brownsville, they both know that Benjamin Wilson's killer belongs in prison, not out on the streets.
* MarriedToTheJob:
** Danny's primarily of the "The Job is That Important" type, but with shades of "Justified Workaholic". Much to his actual wife Linda's chagrin, and often a source of tension when Danny has to leave his family's side to go out on an investigation. Danny also sometimes schedules himself for a lot of extra tours when he and Linda are going through financial difficulties.
** Jamie's first fiancée Sydney Davenport left him early in season 1 as a result of this.
* TheMatchmaker: Nicky is interested in pairing her mom off with her boss, DA Rossalini. She also lobbied for Erin to date the art thief.
* MayorPain:
** Hand-wringing, mincing Frank Russo is a Type B. Fortunately, he seems to hold little to no authority over his Commissioner.
--->'''Frank Reagan:''' [[ParentheticalSwearing I have to take this call]], Your Honor.
** Subverted by his successor, Mayor Carter Poole, who is shown to be genuinely concerned about the welfare of the public, it's just that he and Frank disagree on how to go about things.
* MeaningfulEcho: "Where were you on 9/11?" ("The Job")
* MeaningfulName: Tom Selleck is known to be a staunch Republican in RealLife. [[UsefulNotes/RonaldReagan Three guesses who the family's last name was inspired by]].
* MercyKill: It turns out that a woman died due to this in "Love Lost". She had an incurable illness, wanted to die on her own terms, and her husband euthanized her peacefully. Danny doesn't like it, but he still has to arrest him over this.
* TheMentor: Sergeant Renzulli, Jamie's training officer.
* MinorCrimeRevealsMajorPlot:
** In the season 4 finale, a brothel madam jumps from a penthouse. Danny and Baez are assigned to the case[[note]]which is protocol -- they're there with the assumption it's a murder until evidence is found to suggest otherwise[[/note]]. But then Danny wonders why the Manhattan District Attorney's office would have its investigation squad take over the case. Then he gets more suspicious when he and Baez get orders from the Chief of Department to drop the case. Then Danny finds himself on modified assignment when the D.A.'s office lodges a complaint against him directly to 1PP over a tussle he had with the DA investigators. This gets Erin suspicious since the complaint was filed by Amanda Harris herself. Though on modified assignment, Danny eventually uncovers some evidence suggesting cover-up from within the police department. Erin's digging into the prostitution sting leads her to find evidence suggesting that Amanda's sting is not a sting but an entrapment scheme. A simple suicide thus becomes evidence that Amanda has been conspiring for years to entrap and blackmail lots of people of major influence, like high-level cops, politicians, pro athletes, and various celebrities, in order to guarantee their assistance whenever she needs it.
** In "Home Sweet Home," the arrest of a Rikers Island corrections officer for a DWI traffic stop and discovery of drugs in his car leads to the discovery of a drug trafficking ring in the Riker's Island C-Block.
** Discussed in "Down the Rabbit Hole" over dinner when the Reagans contemplate that it's possible they'll catch serial killer Thomas Wilder through a minor crime, such as unpaid parking tickets (like Son of Sam) or a traffic violation (like Ted Bundy).
* MirandaRights: Used on occasion as in most cop shows, but also parodied once after Danny stops a fleeing suspect with a shopping cart and the guy faceplants.
-->'''Danny:''' [[BondOneLiner You have the right to remain unconscious.]]
* MissingMom: Both Frank and Henry have outlived their wives. Mary Reagan, Frank's late wife, is occasionally mentioned, and Frank still wears his wedding band in remembrance of her, but her absence makes his job all the more difficult because has to go about dealing with problems essentially on his own without her around to help buffer conflicts and arguments, aid his decisions, and alleviate his stress. Because Frank no longer has her to go to, he tends to rely on his father in troubling situations. RuleOfDrama seems to predicate that Frank is a widower to exemplify his role as ThePatriarch and keep him hard-boiled and emotionally distant, and so that the show keeps its serious tone by eliminating the need to script in gratuitous romantic scenes or affections of the like.
* MistakenForCheating: In "The Job," Frank is ditching his detail to make secret visits to a psychiatrist's office. Garrett thinks that Frank is hiding a new girlfriend. He even offers to help cover for him! See also SureLetsGoWithThat below.
-->'''Garrett:''' Too young? Too old?\\
'''Frank:''' More like the type that [[HalfTruth asks too many questions.]]
* MostWritersAreAdults: The show's idea of a realistic message posted by a teenager on a [[FictionalCounterpart Facebook-type networking site]] is "B-T-W homes that video made me L-M-A-O".
* MouthyKid: Nicky has her moments.
* MysteriousPast : Both Danny and Grandpa Henry.
* MysteryMagnet: Reagans have a history of stumbling upon cases while out on the job.
** In "Open Secrets," a kidnapping is discovered because the hostage-taker and victim happened to eat breakfast at a diner at the exact same time that Erin was there with Nicky.
** "Baggage" has Danny and Linda visiting the bank to get their house remortgaged when it's robbed.
** "Thanksgiving" sees a woman get thrown from her apartment window while Jamie and Renzulli are on foot patrol on that block.
** "Stomping Grounds" happens when Danny and Baez stop by a restaurant while working one case, and Baez happens to recognize another customer as someone who as a kid she saw beat a boy to death on her block.
** In "Worst Case Scenario," evidence of a bomb plot in New York City is found after Danny and Baez run into a distraught Arabic-speaking man rambling about his neighbors possessing bombs, at the same time that Jamie and Edie respond to a complaint from a nightclub waitress reporting a man talking with terrorist-like language.
* MythArc: Jamie and The Blue Templars during season 1. Started out as the main thrust of the series but was quickly shoved to the back burner, appearing mainly in BookEnds in the episodes where it's mentioned at all. Season 2 shifts it to Jamie going undercover in the Sanfino crime syndicate. Dropped in season 3.
* {{Nepotism}}:
** ZigZagged. The Reagan clan is ''encouraged'' by family tradition, and Frank tends to prefer using Danny and his current partner for major cases. However there is no string-pulling for them ''per se''[[labelnote:*]]in fact, Jamie is starting to get worried that Frank's attempts to avoid the appearance of nepotism are actually stifling his career[[/labelnote]] and they all become competent at their work.
** In "Love Stories," when Gormley submits Danny's and Baez's names for Medal of Valor consideration, on behalf of their actions in "Partners," Frank is initially reluctant to give a medal to Danny because of the potential that the public might see it as nepotism. When talking about it with Henry, Frank learns that he himself had been passed over for a similar commendation years before when Henry was commissioner (for singlehandedly taking down a fleeing bank robber while off-duty). Frank relents, gives the Medal of Valor to Danny and Baez. When they sit down for Sunday dinner afterwards, Henry and the rest of the family decide to do a private medal ceremony for Frank.
** "Dedications" highlights that Frank once did pull strings while Henry was police commissioner, not to get a commendation, but to squash one.
** In "Knockout Game," Frank rejects an officer who's up for promotion because he's the son of one of the chiefs and he was recommended by Henry. He explains he's trying very hard to keep an old boys' club from developing again. Then he has a one-on-one interview with the officer in question, who agrees with Frank that he most certainly should not be promoted because of personal connections. He wants to get there himself, and actually told his dad ''not'' to have Henry recommend him. Frank is impressed by this and promotes him after all, but he makes it clear he's doing it on the officer's own merits.
* NewscasterCameo: Two episodes show interviews with ''CBS This Morning'' anchor Norah O'Donnell.
* NewMeat: Jamie, in the first season. He levels up his badass and becomes street smart under Renzulli's mentoring.
* NewYorkCityCops: The obvious focus of the series.
* NiceToTheWaiter: Frank to an apologetic cleaning lady who broke a cup. Of course, it was [[ItsAllJunk a gift from the Mayor]], so, no big loss...
* NoBadgeNoProblem: A variant. In "The Uniform", an NYPD Auxiliary Officer[[note]]a volunteer reserve police force which is a subdivision of the NYPD Patrol Services Bureau[[/note]] shoots a guy trying to rob his uncle's diner. The auxiliary in question brought along his own gun, in violation of Auxiliary Police policy.[[note]]Auxiliary officers in New York City are not permitted to carry a sidearm at any time on duty, even if they are independently licensed to carry a firearm, like this guy was. In other jurisdictions within New York State, some police departments do allow their Auxiliary Police officers to carry a firearm.[[/note]] It was eventually ruled a good and justified shooting, and the auxiliary even got into the police academy later on
* NoodleIncident:
** The various times Jamie swallowed things.
** Also, the various times when Erin went out on a date as a teenager and Frank secretly had his off-duty buddies tail her and her date to make sure she was safe. Erin only learns about this when she herself (along with Frank and Henry) stay up late waiting for Nicky to get back from a date ... and Frank reveals he's made similar arrangements for Nicky's protection.
* NonPromotion: After four seasons as Danny's supervisor at the 54th Precinct Detective Squad, Sgt. Sid Gormley impresses Frank with his candor and concern for the rank-and-file cops (after standing up for his own detectives during a COMPSTATS meeting). Frank then informs Gormley that he's making him Dino Arbogast's replacement as Frank's liaison to the regular cops.[[note]]Arbogast had resigned in the season 4 finale when he was among several high-ranking officials caught up in a blackmail operation involving the district attorney's office.[[/note]] However, since the regulations require that the Chief of Department to be at least a captain, Frank instead creates the position of the Special Assistant to the Commissioner, which allows Gormley to assume the duties and authority but not the rank and privileges of the [=CoD=]. While Gormley does receive a promotion to Lieutenant later in season 5, this is mostly still in effect when he has to interface with senior police officers who technically outrank him.
* NotSoDifferent: Between Danny and the victim of the week in "Silver Star", as he sees it.
* OffOnATechnicality: Dick Reed at the start of "Re-Do", courtesy of an overworked crime lab guy making a mistake on the protocols for DNA testing.
* OneSteveLimit:
** Averted. There are three 'Jack's: one of Danny's sons, Erin's ex-husband, and Jackie Curatola.
** Another aversion: in the early seasons, there were two Franks -- Commissioner Frank Reagan, and Mayor Frank Russo. Of course, the latter's name was never mentioned on camera, and when he showed up again in "Men in Black" (when Jamie arrested his daughter for smoking pot in public and mouthing off to him and Vinny), he's introduced as Robert Levitt.
* OnceAnEpisode: The Reagan family holds a conference over dinner.
** A variation in "Thanksgiving": When Henry is in the hospital, the family brings the dinner to ''him''. And the seating arrangement is the same.
** Another variation occurs in the Season 5 finale, after Linda is shot in the crossfire of an assassination, and the family has still manages to have Sunday dinner together thanks to Linda and Danny "joining" them by Skype from Linda's hospital room.
* OpenMouthInsertFoot: "Loose Lips" sees Nicky get turned down for admission at one college due to some disparaging remarks she made on Twitter about one of her teachers. Later on, Henry becomes the subject of controversy when he's caught on camera conversing with a friend about one of his old war stories (see PapaWolf).
* OrderVersusChaos: A subtle theme throughout the series, with [[ByTheBookCop Frank and Jamie]] representing order and [[CowboyCop Danny]] being chaos.
* OurFounder: Frank is a fan of President (and former NYC Police Commissioner) UsefulNotes/TheodoreRoosevelt. A big picture of TR hangs in his office.
* OurPresidentsAreDifferent: Or perhaps Our Mayors Are Different. Mayor Carter Poole is a Mayor Personable/Mayor Minority twofer, with elements of BarackObama and Corey Booker.
* OutOfFocus: In general, [[TwoLinesNoWaiting there will be three or four plots going on]], typically an A-plot involving Danny solving a typical murder case, a B-plot involving Jamie and his partner on a typical day of patrol, and a C-plot involving either Erin prosecuting a case or Frank dealing with NYPD politics.
** Example: there is the occasional episode that doesn't have a plot for Danny (although Danny will still show as part of the OnceAnEpisode family dinner). These episodes include cases like "With Friends Like These" (which splits time between Erin going back through an unsolved murder case, Jamie and Edie trying to help a mentally ill woman, and Frank dealing with tensions between the NYPD and FDNY), "Hold Outs" (which involves Erin dealing with a murder case that had a mistrial while Jamie and Edie work as part of a task force dealing with some street gang issues), and "Custody Battle", where there are two plotlines that both involve Jamie -- the A-plot of a death-in-custody involving an officer who used an illegal chokehold, and the B-plot of Jamie convincing Edie to visit her incarcerated father.
* OutrankingYourJob:
** Generally averted. Captains, Lieutenants and Sergeants are depicted as supervisors, who almost never personally conduct investigations or make arrests.
** Frank sometimes toes the line on this. There are occasions where he'll order an investigation into a matter, but he doesn't actively participate in said investigation and has people who do the legwork and report back to him.
** Jamie seems to be an inversion. While he's just an officer, many of his plots have him do things that are more likely to be assigned to a detective.
[[/folder]]

[[folder:P-T]]
* PapaWolf:
** In one episode Frank [[CrowningMomentOfAwesome personally shoots a serial killer]] who is attempting to [[StuffedIntoTheFridge rape and kill]] Erin.
** Henry certainly applies. When Frank was shot, the entire family waits in the waiting room. After revealing that he has a gun, Henry sits in front and the show proceeds to time-skip a few hours. You don't think much of it, until you realize that Henry is the only one who's relatively alert. Meaning that he was guarding his family, as the only way to get to them was to go through him.
** And then there was the time Henry pulled a gun on an EMT to save his son from meningitis.
** Danny feels this way when his immediate family is harmed, as notably shown in "The Job".
** Danny's reaction when Nicky herself is abducted by a serial killer is as angry and terrified as if she were his daughter instead of niece.
** It's also discussed earlier, as when Jamie is under an Internal Affairs investigation, Frank resists the temptation to tell IA to let him slide. Henry helps out by letting him know that the same thing happened to Frank when he was Commissioner, but he let IA go through because he knew Frank would be cleared. He was, and so is Jamie.
** In "Loose Lips," Henry causes a scandal when a recording of one of his old war stories goes on YouTube: A cop was put under threat by a criminal gang and Henry ordered his men to lean on every crook in the city to get the word out that the cop was protected; it worked and the cop never knew. Frank calls Henry on this -- Henry reveals that Frank was that cop.
** In "Personal Business," an off-duty sergeant is shopping with his daughter at a bodega when armed gunmen rob the place, fatally shoot the cashier, steal from the register, and flee. It's a stinker because the sergeant was busy shielding his daughter the whole time, when protocol is that he should have intervened as he had his off-duty gun on him.
* PassiveAggressiveKombat: Danny and Linda's marital strife spills over into a family dinner during grace. Danny compliments his wife's prayer, "especially that part about ''making good decisions''."
-->'''Linda:''' I was saying grace.\\
'''Danny:''' Yeah, and [[AndImTheQueenOfSheba Erin's spinach]] [[FeminineWomenCanCook isn't soggy]].\\
[''Erin [[ImStandingRightHere glares at him]]''.]
* PatrickStewartSpeech: Grandpa Reagan in "The Job". He knows God has a plan.
* PassedOverInheritance: In one season 1 episode, Jamie and Renzulli meet an obsessive-compulsive woman who is convinced there's a rapist creeping around her apartment. Turns out it's just her deadbeat brother, who is [[GasLighting hoping to have her declared crazy]] so he can inherit her cash.
* PlayingGertrude: Len Cariou plays Henry Reagan, who is supposed to be Frank Reagan's father. In real life, Cariou is only six years older than Tom Selleck. Cariou wore makeup to look even older.
* ThePatriarch: Frank.
* PluckyComicRelief: Renzulli.
* PerpSweating: A literal example in "Immunity". An Argentinian diplomat's son is protected by [[DiplomaticImpunity diplomatic immunity]], so he's invited to be questioned at the station. Danny deliberately has the A/C unit in the interrogation room shut off, so the guy starts to sweat. Then, after he leaves, the crime scene techs collect the guy's DNA, which is used to nail him (the guy's father is convinced to waive diplomatic immunity, as DNA evidence also proves he's guilty of a similar crime in Argentina, where immunity would not apply and prisons are ''much'' worse).
* PoliceBrutality:
** Danny has a [[WhatTheHellHero disturbing]] tendency toward this and sometimes the audience can't tell how far he will go. Given that it's usually towards quite despicable criminals, it comes off as PayEvilUntoEvil.
** In "Whistle Blower", an incriminating video of a cop assaulting an old man [[InstantHumiliationJustAddYoutube goes viral on]] YouTube. [[spoiler:Actually a subversion: once they were able to subpoena the ''unedited'' version it was clear the old man had made a grab for the officer's pistol.]]
-->'''Garrett''': There's even a music video version now. Set to "[[Music/{{Queen}} Another One Bites the Dust]]." Wanna see it?
** In "Power of the Press," a police officer wearing a body camera as part of a pilot program gets into a confrontation with a suspect. However, the camera feed cut off right before the actual physical hit due to a malfunction, making it look like a deliberate beating. Eventually, video from another witness shows that the suspect took the first swing.
** In one season 4 episode, Baez questions a racist suspect/witness of a mosque bombing. Her response to him mouthing off to her is to knee him in the groin; this is played for laughs. Made worse due to the next scene involving a man punching a police officer in the face for harassing him, which everyone takes dead serious.
** Danny's actual cases of brutality give him a reputation that causes him to get in more serious trouble when a false accusation is lodged against him. This happens in "Excessive Force," when he chases a robber into an apartment building, who then jumps from a third-story window (and injures himself) after Danny gives him the idea with an empty threat. The robber immediately starts screaming "police brutality." With no one able to back up Danny's claims, especially given his history, he ends up in the crosshairs of Reverend Potter's anti-NYPD agenda. Eventually, though, it's revealed that a young Hispanic boy saw the whole thing, but, since his family are illegal immigrants, his parents don't want him testifying. Furthermore, Reverend Potter buys the family's silence by getting them a better apartment and offering to help with their visa problem. Once this is revealed, not only is Danny cleared, but Frank threatens Potter with arrest if he pushes the matter any further.
* PoliticallyIncorrectVillain:
** A crooked developer rants about "union bloodsuckers."
--->'''Danny:''' [[ImStandingRightHere We're in a union]].\\
'''Parker:''' [[SarcasmMode And I'm happy for you]].
** In "The Job", a suburbanite father is waging a one-man war against "halfway house dirtbags." He ends up on Danny's bad side after he fires at Danny for interrupting him in the midst of attempting to kill one such victim and inadvertently endangered Danny's family.[[note]]The would-be victim is being chased by said father when he darts out into the street, and is struck nonfatally by Danny's oncoming car. Danny gets out and begins checking on the guy he hit, at which point the gunman appears and tells Danny (at gunpoint) to back away. Danny pretends to do so, then draws his pistol. The gunman opens fire and flees. Danny is pissed because at least one bullet went through the front and rear windshields of his car and came very close to striking his kids.[[/note]]
** A pair of junkies holding up an immigrant family ("Parenthood"). "I know you '''people''' don't use banks. Where's the money, ''chica''?"
* PoliticallyMotivatedTeacher: Nicky had a one at her old Catholic school. She was very left-wing, hated law enforcement and bullied Nicky every day because she she came from a family of cops.
* PompousPoliticalPundit: In "Inside Jobs," there's Curtis Swint, the borderline white-supremacist radio host who wants to make a live broadcast from a New York theater. Upon getting word of the potential risks, Frank must face the [[ToBeLawfulOrGood dilemma]] of protecting Swint's constitutionally guaranteed rights to freedom of speech and assembly, in spite of his own disdain for Swint's message, not to mention the absolute disgust of those who want to shut down the show, like a Latino congressman, Mayor Poole, and [[MalcolmXerox Reverend Potter]]. [[spoiler:He ends up foiling Mayor Poole's attempt at BotheringByTheBook to shut down the theater (due to the discovery that the theatre's boiler is overdue for an inspection), then places Swint's police protection ''inside'' the theater, and arranges for it to be comprised entirely of non-white officers led by a [[ScaryBlackMan large black sergeant]][[note]]who, by "coincidence", used to be a blindside tackle on Swint's home Kansas State Wildcats[[/note]].]]
* ThePowerOfLegacy: In "Unfinished Business," after failing to talk a traumatized war veteran out of jumping off a roof, Danny lies on his incident report, claiming the man had changed his mind about suicide, but slipped and fallen accidentally. That way, the soldier's son will be reassured his father hadn't intended to die and leave his family grief-stricken.
* PragmaticVillainy: In "Officer Down", TheMafia helps out in hunting down the {{Cop Killer}}s. Henry notes that when he was on the force the Five Families had explicit rules that cops were off limits because [[PragmaticVillainy dead cops are even worse for business than live ones]].
* PrinciplesZealot: Erin is an assistant district attorney and always getting in arguments with the other members of the family about the tension between legal protection, and law enforcement efficiency. An old problem that will always remain and is well handled in the show.
* PromotedToOpeningTitles: Amy Carlson (Linda) and Sami Gayle (Nicky) are promoted from "Also Starring" to the opening titles beginning in season 5.
* ProsceniumReveal: In "Stomping Grounds," Jamie and Janko appear to be responding to an armed robber at a pharmacy holding up a cashier at gunpoint. Jamie shoots, and inadvertently hits a terrified customer, who falls. Then an alarm goes off, and it's revealed they are actually on a training course.
* ProtectThisHouse: A father shoots dead the burglar who attacked his family, which is good enough for Danny. Not so much for the law, however, because a) the suspect was shot ''outside'' of the home, and b) the shooter is an illegal immigrant. [[spoiler:In the end Danny coaches him on his confession to paint the case in the best possible light for the D.A.]]
* PulledFromYourDayOff: In "A Night on the Town," Danny ends up catching a case right when he and Linda are about to have a romantic weekend of their own. He ends up trying and failing to juggle both, with her letting him out of a play they had nonrefundable tickets to by calling a friend.
* APupilOfMineUntilHeTurnedToEvil: Billy Flood, one of the finest officers in Frank's unit.
* PutDownYourGunAndStepAway:
** In "Re-Do," Reed tries it on Frank, holding Erin hostage. Frank's response is to [[NoNonsenseNemesis just shoot him]].
** A perp in Season 2 gets the drop on Jackie and tries to invoke this on Danny, who acts as if he's going to play this straight... and then Jackie slips out of the perp's grasp, grabs her gun back, and Danny's gun is back on target.
* QuoteToQuoteCombat:
** In "Black and Blue" Frank tangles with Rev. Darnell Potter, [[MalcolmXerox a spotlight-loving black pastor who has an axe to grind with the NYPD over race issues]]. Potter walks into a meeting between himself, Frank, and the mayor throwing out a quote by UsefulNotes/MalcolmX. Frank asks for the names of the men in Potter's church who shoved Jamie and Sgt. Renzulli down a flight of stairs; Potter refuses and accuses him of being unwilling to seek a consensus.
--> '''Frank:''' A true leader is not a seeker of consensus, but a molder of consensus. [''walks out'']
---> [''Potter looks confusedly at the mayor.'']
--> '''Mayor:''' [''chuckles''] {{Martin Luther King|Jr}}.
** In "Sins of the Father", Danny's case involves a father seeking vengeance for his daughter, who committed suicide after being fired from a porn studio (he was targeting the crew). During interrogation:
-->'''Jerry Phillips:''' "For if there was harm, you shall appoint as penalty life for life, eye for eye, tooth for tooth." Exodus 21:23.\\
'''Danny:''' "Do not take vengeance against evil, but wait for the Lord and He will avenge you." Proverbs 20:22.
* RealityEnsues:
** In the pilot, Danny [[JackBauerInterrogationTechnique uses physical torture on a ]] [[PayEvilUntoEvil child molester]] to find a kidnapped girl. The child molester slides because his lawyer successfully argues that his confession admitted under duress be thrown out, forcing Danny to find other evidence to put him away. He is also demoted from Major Case Squad to a precinct detective by the next episode.
** "Privilege". Bad guy has DiplomaticImpunity? Then just [[Film/LethalWeapon2 revoke]] it! But not so fast -- his government can still deny you the authority to do so.
** "Re-Do" -- Corruption and cutbacks in government spending can ultimately endanger public lives, as shown when a foul-up of DNA evidence caused by an overworked technician causes a pedophile and a serial rapist-murderer to be released. While Erin uses loopholes to get the pedophile re-committed, the latter ends up continuing his terror by intimidating his surviving victim at every turn, and even tries to go after Erin, only to be shot dead by Frank.
** "Excessive Force" sees Danny get wrongly accused of throwing a teenage thief out of an apartment window after a foot chase (the guy actually jumped out the window and started screaming "police brutality!"). His prior complaint history means exonerating him in this one false case is not a cakewalk.
** Danny, playing the CowboyCop as usual, goes charging into a house solo after [[SerialKiller Thomas Wilder]], and because he did so without waiting for Baez or ESU to back him up, the guy beats him up with a crowbar and escapes.
*** The Thomas Wilder case doesn't stop with his death episode. The first shot of the season 7 premiere is of Danny having recurring nightmares about shooting Wilder. And the premise of the episode is that the state's Attorney General is investigating Danny because new evidence has come up against him (Wilder kept recordings of all his phone calls with Danny, some of which include Danny saying things suggesting murderous intent towards Wilder). Not only that, but Danny's prior complaint history gets used against him.
* ARealManIsAKiller: The letter of the trope is averted rather thoroughly by leaving Jamie's first kill until the middle of season three and making it be a SuicideByCop case. Jamie, already in the grips of TheseHandsHaveKilled, is understandably horrified, and not once does anyone treat it as a rite of passage. During the same episode Frank recounts a statistic that less than five percent of cops ever have to fire their weapons outside the range, and less than five percent of those shootings are fatal. On the other hand, Jamie's first ''shooting'', which was nonfatal, gets a passing treatment as this by the IA detective doing the routine shooting investigation, who tells him to [[PlayedForLaughs enjoy the paperwork]].
* RealMenLoveJesus: Like true Irish-Americans, the Reagans are good Catholics. However, in one season 3 episode Danny admits to only trying to set an example for his kids and that he lost his faith a long time ago.
** Despite the above, Danny seems ''very'' open in one episode to the idea that God talked to a girl concerning the alleged murder of her mother--even when Erin and Jackie needle him for it. The episode ends with him in a cute moment of trying to recreate the girl's "vision" position for himself.
* TheReasonYouSuckSpeech: Naturally there are going to be the occasional speeches that are like this.
* ReasonableAuthorityFigure : Frank Reagan would put {{Cincinnatus}} to shame:
--> [''to the mayor''] "I serve at your pleasure... but I ''work'' for the people of New York City."
* ReassignedToAntarctica: Staten Island is considered the dumping ground for NYPD cops who screw up on the job. The fear of getting transferred there is mentioned repeatedly:
** When Frank's position as Commissioner seems to be at stake, Gormley dreads the possibility of getting transferred to Staten Island. In the season 5 premiere, he'd feared that this would be his fate after he lashed out at Frank for not standing up to Lt. James [=McCarthy=], who'd been accused of using excessive force on a crazed man. A few episodes later, he fears being terminated after shooting his mouth off at a COMPSTATS meeting and is even asked to bring his box when Frank summons him to 1PP. But Frank surprises him by instead promoting him to Special Assistant to the Commissioner.
** In "Stomping Grounds":
*** Lt. Tim Harrison is a freshly retired cop who served 40 years on the job and was a favorite of Henry's (which, Frank reluctantly admits, is the only reason he kept him on when his sell-by date as a reliable cop had long passed). But hours after his retirement party, he shoots two black people on the subway (a guy trying to rob him, and another guy who was actually trying to intervene). During the manhunt, Frank confides to Henry that Harrison had a history of bigotry when it came to blacks. In fact, this got to the point that Frank had to have him transferred to Staten Island explicitly because Staten Island had a 75% white population.
*** Jamie and Edie get a new training officer, Sgt. Ray Langley, who has a habit of hitting on female officers he's trained in every precinct, most recently Edie. Jamie feels like Langley is abusing his power by doing so. So he gets rid of him by suggesting he put in a transfer to Staten Island.
** "After Hours" concerns Jimmy Burke, a former partner of Frank's who took two bullets for him on a rooftop. He has been promoted to Inspector and placed in command of the 15th Precinct. While up for a promotion to Deputy Chief, it's discovered that as the Deputy Commander of Patrol Borough Manhattan South he has been cooking the books for his precinct's [=CompStats=] (artificially lowering crime rates by classifying obvious felonies as misdemeanors instead). In part, he justifies it on the grounds of how his 40-year career has left him with several failed marriages, alimonies, and college tuitions. He intended to get his promotion then call it quits. Frank allows Jimmy to retire with his reputation intact, rather than face the alternate option: demotion to Captain and reassignment to the 128th Precinct in Staten Island.
* RedOniBlueOni:
** Danny Reagan is {{red|Oni}} to his partner Jackie's (fairly subtle) {{blue|Oni}}. GoodCopBadCop also applies, in reverse order.
** Danny is also {{red|Oni}} to his sister Erin's {{blue|Oni}}. And to Jamie's {{blue|Oni}}, for that matter.
* ReformedCriminal: Ray Bell, the barber from "The Life We Chose."
* RetiredBadass: [[BadassGrandpa Great-Grandpa Henry]].
* {{Retirony}}:
** Frank's friend John was leaving for a vacation when the World Trade Center was hit.
** Roland Gates is shot on the eve of his daughter's christening.
* RevolversAreJustBetter:
** Subverted by [[GoodOldWays Henry]], who points out that Frank would have more firepower with a Glock. Frank concedes the point, and states his reason why in a CrowningMomentOfHeartwarming:
--> "I like carrying your gun, Pop."
** In the PapaWolf example above, Frank proved pretty conclusively he doesn't ''need'' a Glock. [[BoomHeadshot His .38 Special works just fine.]]
** "Dedication" reveals that despite his earlier advice to Frank, Henry carries a .357 Magnum revolver.
* RewindReplayRepeat: Used in "All the News That's Fit to Click", Danny and Baez play back the 911 call that was made to lure Jamie, Janko, and the reporter they were riding with, into an ambush. In a scene that is a ShoutOut to ''Film/TheFugitive'', they have the TARU tech isolate the background noises, which reveal a 'next train' announcement, pinpointing the exact subway station where the call originated.
* RippedFromTheHeadlines: It's not uncommon to see an episode with a plotline based on an actual controversial moment in the [=NYPD=]'s lengthy history, or even an actual case.
** The second episode of season 1 involves a good Samaritan who killed a criminal on the subway who was about to rape a woman, only for it to turn out that he got the gun illegally because of an earlier arrest from his late teens[[note]]It's a crime for a felon to possess a firearm in almost every state[[/note]] (which is also the reason he didn't come forward right away). It brings to mind Bernhard Goetz, the "Subway Vigilante" who shot and wounded four men who tried to mug him on the 2 train in December 1984, and was acquitted of all charges except for carrying an unlicensed firearm.
** In "Black and Blue", Reverend Potter has a friend fake a 9-1-1 phone call and then has his parishioners attack Jamie and Sgt. Renzulli when they respond, putting Renzulli in the hospital with a concussion. It's a milder version of [[https://en.wikipedia.org/wiki/1972_Harlem_mosque_incident a 1972 incident]] where police officers responded to a fake 911 call planted at a Harlem mosque, were attacked by parishioners inside, and in which one officer was killed.
** "Loss of Faith" has the 12th Precinct on high alert due to word that a former officer terminated from there might be en route to New York City to exact revenge against the cops responsible for his dismissal. The plotline is kinda like that of the case of Christopher Dorner, an ex-cop who directed revenge against the LAPD for what he perceived as a wrongful termination.
** In the season 5 episode "Baggage," the NYPD is dealing with Spanky, a guerilla street artist in the vein of [[http://en.wikipedia.org/wiki/Banksy Banksy]] who leaves inflatable balloons that emerge from suspicious packages left in public places.
** "Blast from the Past" concerns that an officer named Thomas Scully is up for promotion to Sergeant. But 14 years earlier he was one of four officers who [[ThereIsNoKillLikeOverkill shot an unarmed Muslim teen 61 times]] [[ShootHimHeHasAWallet while he was reaching for his wallet]]. The descriptions of what happened echo the February 4, 1999 shooting of Amadou Diallo, where four NYPD officers fired a total of 41 rounds at a pedestrian whom they thought was pulling out a gun that turned out to be his wallet. It was for a time the poster-child incident of the ongoing debate over police conduct and brutality in the United States. Also, considering that Diallo was a black man, there was also suspicion of racism.
** In "Blowback," public outrage is directed at the NYPD after a grand jury doesn't indict Officer Eric Russell for the controversial shooting of a knife-wielding teenager that was caught on his body cam, and then someone in Erin's office leaks the body cam footage to the Internet. Shortly thereafter, Officer Mark Hayes is shot and critically wounded in what appears to be a retaliatory incident. This reflects the outrage felt in real life when a grand jury failed to indict Daniel Pantaleo, the officer who used a chokehold on Eric Garner in July 2014. Subsequently, in December 2014, a few weeks after the verdict, NYPD Officers Wenjian Liu and Rafael Ramos were shot to death in their patrol car on a Brooklyn street, and the gunman then committed suicide in a nearby subway station. It was established to have been a retaliation hit for both Garner's death and the officer-involved shooting of Ferguson, Missouri teenager Michael Brown.
** In "Whistleblowers", Frank is dealing with allegations from an idealistic cop who claims to have evidence of abuse of power in high crime neighborhoods. The plotline itself seems to be a big reference to [[https://en.wikipedia.org/wiki/Adrian_Schoolcraft Adrian Schoolcraft]], an NYPD cop who secretly recorded several conversations and alleged that arrest quotas were leading to police abuses such as wrongful arrests, while the emphasis on fighting crime sometimes resulted in underreporting of crimes to keep the numbers down. He was reportedly harassed and reassigned to a desk job, even physically abducted from his apartment by an ESU team and forcibly admitted to a psychiatric facility, where he was held against his will for a week.
* RogueJuror:
** Unusually done in the fourth season episode "Justice Served" when Danny is the sole holdout for a "not guilty" verdict in a murder trial.
** "Hold Outs" in season 6 features something similar. The murder case of a guy killed during a carjacking seemed open-and-shut, but was declared a mistrial because one of the jurors voted "not guilty". An interview by Erin with the juror in question reveals that unlike the other jurors, he saw evidence in the police report that exonerated the defendant (a witness statement that said a white man, not a black man, pulled the trigger). The subsequent investigation by Erin and one of her office's investigators determines that it wasn't a carjacking, but rather, [[spoiler:the wife of the deceased was cheating on him, and plotted with her lover to have the man killed.]]
* {{Roofhopping}}: Danny vs. a hood in "The Uniform".
* RuleOfDrama: It's unlikely that a guy who despises politics (and politicians, and publicity, and reporters) as much as Frank Reagan would be appointed NYPD Commissioner.
* SaltAndPepper: Frank Reagan and Mayor Poole.
* SassyBlackWoman:
** Danny locks horns with a power-mad [[DoctorJerk nurse]] in "Leap of Faith."
** Lt. Carver, Danny's replacement supervisor after Gormley gets promoted to be Frank's Special Assistant, played by [=LaTanya=] Richardson.
* TheScapegoat: In "Friendly Fire," Linda chews Danny out over not mowing the lawn, and the ''world'' becomes this trope. Culminates in a still-agitated Danny accidentally gunning down a fellow cop.
* ScrewTheRulesIHaveConnections:
** Inverted in "Parenthood," when Mayor Carter Poole's illegitimate daughter Ariel joins a protest and is caught up in the ensuring dragnet. Ariel doesn't demand special treatment, but her parents politely suggest, separately, that Frank had better let the matter drop.
** Averted with Danny, who says he never believes in using his father's name to get special treatment.
** Averted with Jamie, of course. In "Critical Condition," Sosa suggests that with Jamie's family connections, he could have made Detective by now.
** When Jamie is accused of undue force (he was actually trying to knock someone out of the path of an oncoming biker), a D.A. makes it clear she thinks he's guilty and his father must be covering for him. When video proves Jamie innocent, the woman continues to snark about his family always getting their way.
-->'''Jamie''': If my family really threw their weight around like you say ... how smart is it for you to be insulting us?
** Played with in "Men in Black", when Jamie and Vinny catch the previous mayor's daughter and her friend in the act of smoking pot on a park bench. When preparing to arrest them:
--->'''Rebecca Levitt:''' Don't you guys have any real criminals to chase?
--->'''Jamie Reagan:''' You might want to ease up on that attitude, Rebecca.
--->'''Rebecca Levitt:''' You don't know who my father is.
--->'''Jamie Reagan:''' [''smirks''] [[ThreatBackfire I don't really care.]]
*** Of course, after a discussion with Erin, her dad tells the judge:
---> "I would like to tell the court that my daughter is a wonderful young woman ... [''{{beat}}''] ... who needs to learn to respect the law."
** The bad guys don't have a monopoly on this. In "Warriors" the State Department refuses to grant political asylum to a Turkish cellist in danger of being the victim of an [[HonorRelatedAbuse honor killing]] if she returns home (for having dated and slept with an American during the tour). [[spoiler:Frank talks a contact into getting the New York Philharmonic Orchestra to hire her, and his opposite number at State, the episode's SympatheticInspectorAntagonist, expedites a work visa.]]
** There's an implication that when Nicky is arrested with her friends in "Road to Hell" after drugs are found in the car during a traffic stop that Nicky was expecting the process to be easier for her on the basis of her last name.
** In "In the Box," Garrett's stepson has been arrested for scoring oxycodone during an observational buy. Garrett wants to have him released into rehab. However, Frank is suspicious of the circumstances, and has Baker investigate, discovering that Garrett has used his pull at 1PP to keep Sam out of prison on several prior occasions. Frank confronts Garrett and gets him to see that he's enabling his stepson's drug habit and not helping him.
** In "Dedications," Frank brings up having to use Henry's influence to squash a commendation, when a botched attempt to arrest the head of a Westies gang faction led to the death of the guy's wife and grandson.
* SeductionProofMarriage: "After Hours" provides the page quote. A key witness in Danny's Case of the Week, a hot nightclub owner named Sabrina, get the hots for Danny. He indulges her a little bit (one dance) to get her to open up, but firmly rejects her trying to take it further because he's HappilyMarried.
--> '''Sabrina:''' Let me ask you a question. [[WhatsHeGotThatIAintGot What does she got that I don't have?]]\\
'''Danny:''' Me.
* SemperFi: Henry, Frank and Danny are all Marine veterans who've seen combat (Korea, Vietnam and Iraq, respectively).
* SerialKiller: One of Danny and Jackie's [[MonsterOfTheWeek Perps of the Week]] was a SerialKiller that preyed on call girls.
* SeriousBusiness: Danny recalls almost beating up another dad at a little league game.
* ShameIfSomethingHappened: In season 1, as Jamie picks up Joe's old case, Sonny Malevski keeps reappearing to turn up the heat.
* ShootHimHeHasAWallet:
** In "Friendly Fire," Danny shoots a guy who seems to be holding a gun. Only after the guy falls does he and Jackie realize the guy was an off-duty police officer and was about to show his badge (and failed to register Danny's command to stop because he had just sustained a head wound from interfering in a fight with a mother and her drug-dealing son). Danny is in serious trouble while Internal Affairs investigates whether it was an honest mistake or negligence.
** In season 6, an officer named Thomas Scully is up for promotion to Sergeant. However Frank has reservations about the promotion because Scully was one of four officers tried and acquitted 14 years earlier for the death of an unarmed Muslim teen who was shot ''[[ThereIsNoKillLikeOverkill sixty-one times]]'' in a dark apartment. Such a promotion could be bad as far as public relations are concerned, given the current climate. Frank talks with Jamie, who says that Scully was one of his instructors at the Academy. When he brought up the shooting, he said that at the time, his precinct was on edge, given it was just after 9/11, there was a tip that someone of Arab ethnicity was stockpiling weaponry, and a cop in their precinct had been shot in a housing project just days before the incident. This caused a perfect storm of circumstances that caused them to gun down the teen when in reality he was just reaching for his wallet.
** When Danny catches up to serial killer Thomas Wilder, Wilder has his hands behind his back while Danny has him at gunpoint. Wilder suddenly moves his hands as if drawing a gun and Danny fatally shoots him (Wilder's hands were empty). The fact that Wilder wasn't armed causes Danny to be subject to another inquiry from the State's Attorney General when new evidence comes up (recorded phone calls) suggesting Danny went into the clearing with the intent of shooting Wilder. Danny sees the whole inquiry as a farce, and after being grilled, gets up from the stand, proceeding to make a defense by putting the average citizen in his shoes to get a feeling of what it was like for him. After quietly explaining the set-up of the scenario, he suddenly shouts "BANG!" at the spectators, to demonstrate how fast anyone would have to make a decision if they were in a similar situation.
* ShootTheHostageTaker: At the end of the episode "Re-Do", a serial rapist takes Erin hostage within sight of Frank, and tries to invoke "PutDownYourGunAndStepAway". Or that was the plan, anyway: [[PapaWolf Frank puts a .38 round]] [[BoomHeadshot through his forehead]] [[KilledMidSentence before he can finish the sentence]].
* ShownTheirWork: Different elements of the NYPD are portrayed quite accurately depending on episode.
** In "Loss of Faith," Jamie's precinct is on high alert due to the news that an ex-cop who worked there is coming to New York City to exact revenge on the officers who played a role in his expulsion. When Frank is debriefing the officers, among things he tells them to do is wear the "color of the day" on full display. The "color of the day" is a policy used by the NYPD that allows plainclothes and undercover officers to identify themselves to uniformed officers so as to avoid a friendly fire incident, through a prominent article of clothing in that color. Why this system is necessary is shown in the same episode when, while on plainclothes patrol, Vinny forgets to wear the color of the day and almost gets himself shot by an officer who mistakes him for the ex-cop they're looking for.
** The use of a former NYPD detective as a police technical advisor.
* ShutUpHannibal: Erin delivers one to an AmoralAttorney in ''Innocence'.
--> "How does it feel to be defending a rapist?"
** She delivers another at the end of "Whistleblower", in one of her most powerful scenes of the season, if not the whole show.
--> [[spoiler:'''Wife of the Victim''']]: I don't know what kinda fancy place you grew up in, but where I come from, there is ''nothing'' worse than a rat!\\
'''Erin:''' ''That'' '''''rat''''' was [[spoiler:the father of your ''children''.]] And where I come from, ''nothing'' is more important than that.
* SiblingRivalry: Every now and then, Erin and Danny resort to acting like preteen siblings and have at each other.
* SickbedSlaying: Narrowly averted with a counter-terror agent who survived his shooting.
* SlobsVersusSnobs: So far, there is recurring tension between the Reagans who 'did good' and their friends who grew up on the wrong side of the tracks. In a toss-up, the underprivileged tend to side with criminals.
* SmugSnake: Sonny Malevski.
* SoHappyTogether: The victim of "Whistle Blower" is shot on his anniversary.
* SoundtrackDissonance: In "Re-Do", Dick Reed the serial rapist obsessively plays a vinyl record of "Ave Maria."
* TheSouthpaw: Danny shoots left-handed.
* StopOrIShootMyself: In the Season One finale, Sonny Malevski, member of the Blue Templar and the guy who killed Joe, pulls this when Frank shows up to arrest the Blue Templar. Frank's response?
--> "We all die, Sonny, it's just a question of when."
* StrappedToABomb: In the season 3 premiere, Benjamin Walker, an ex-con Danny put away, takes Jackie hostage and ties her to a bomb in order to draw Danny out.
* StrawmanPolitical:
** The show has right-wing bent and it's very unsympathetic to the various social justice movements, exemplified by the Reverend Darnell Potter, a black SinisterMinister with a taste for the media spotlight and a habit of making false PoliceBrutality accusations on specious evidence (even deliberately manufacturing a confrontation that put Sgt. Renzulli in the hospital in his first appearance).
** Then there was the time Nicky's LGBT rights activist friend graffitied her own dorm wall with misogynistic slurs to draw attention, then attempted suicide after being found out.
** Once in a while the show will make a token effort to say the activists are raising a good point in an unpleasant way, but usually not.
** However, the aforementioned stories are TruthInTelevision, being based on RealLife events.
* StrawmanU: Much to Nicky's displeasure she finds out that Columbia falls under this this when radical left students protest Frank while he's trying to give speech, to the point he's driven off the stage after five minutes. Poor Nicky is in tears throughout the whole thing.
* StrippingSnag: Danny once got his suit jacket caught in a fleeing suspect's car door and frantically ran after the car while trying to get out of the coat.
* SuicideNotMurder: In the season 4 episode "The Truth About Lying," Danny and Baez get put on the case of a homeless guy who seemingly shoved a woman in front of a subway train. It looks like homicide, and they bring in the guy -- who is somewhat mentally challenged and prone to throwing tantrums (which is why he's nicknamed "the Hulk") -- and he pleads that he wasn't trying to kill her but trying to save her. This prompts the detectives to rewatch the surveillance video of the incident more closely and indeed they notice that the woman stomps on the man's foot, trying to get him to let go of her, and then jumped in front of the train. She was committing suicide, as the result of cyberbullying.
* SureLetsGoWithThat: When Frank returns from his secret trip to the psychiatrist, Garrett tries to figure out where Frank's been, and after several vague answers to Garrett's questions, arrives at the conclusion that Frank is dating someone secretly. Frank sees no reason to correct him on this point, since Reagans don't go to psychiatrists. See also MistakenForCheating above.
* SuspiciousSpending: In "The Poor Door," the ''New York Daily News'' catches Louis Weems, a veteran Narcotics detective (and former drinking buddy of Gormley's) from Brooklyn North driving a brand-new red Ferrari that costs about the equivalent of three years' detective salary before taxes. Frank has to act because the fact that the press will take the fact that Weems seizes piles of drugs and drug money for a living and driving a car he shouldn't be able to afford, and conclude he is corrupt. As it turns out, he's been engaging in some shady real-estate investments, by flipping buildings that he conducts drug raids on.
* SwallowTheKey: Frank Reagan didn't raise no fools. When confronted by some mob brokers, Jamie gulps down the thumbdrive he used to hack their finances. This to the family's utmost amusement as they reminisce about all the other things Jamie has swallowed, like the key to the Reagans' liquor cabinet.
* SuicideByCop:
** Jamie's first line-of-duty kill was of a man armed with a gun in Washington Square Park. It's discovered to be one when Danny uncovers that the 911 call that brought Jamie and Vinny to the park came from the victim proper.
** An ''inversion'' (Suicide by Criminal) happens in "Unsung Heroes". Jamie locks heads with the hotheaded Sergeant Mabrey, who disregards protocol on a hostage situation.[[note]]There is a perp barricaded in a house. Jamie wants to sit tight and call in ESU and a hostage negotiator. Mabrey goes in guns blazing and the hostage taker is shot. Jamie thinks that the hostage could've been hurt or killed going in without backup.[[/note]] After getting Jamie's side of the story, Gormley discovers that Mabrey has been involved in five other incidents in the past year where he did save lives, but in the process, he endangered himself or others around him.[[note]]Such as taking down an EDP armed with a knife, jumping off a subway platform to rescue an intoxicated passenger who'd fallen onto the tracks, being first on scene to an armed robbery outside the confines of his precinct.[[/note]] Turns out he's dying from pancreatic cancer and is trying to get himself killed so that his family can collect on his insurance.
* TakeAThirdOption: Frank is really good at finding the third option in ToBeLawfulOrGood dilemmas in the last few minutes of the episode.
** When Valverde, a brutal dictator from an unnamed BananaRepublic country, comes to New York City for medical treatment, there is much outcry from the public due to the actions he's carried out back home.[[note]]According to Frank, Valverde ordered soldiers to open fire on peaceful protesters and then barred the wounded from hospitals, including women and children, a mere two days before his phony election.[[/note]] Frank himself even personally admits he would never let the guy set foot in New York City if he had his way. So [[spoiler:Frank arranges for Valverde to receive police protection before and during his surgery, then as soon as he's able to be moved he puts him on a plane back home, where a popular uprising has just deposed his government]].
** In "Inside Jobs," New York City is about to receive a visit from Curtis Swint, a [[PompousPoliticalPundit white supremacist radio host]] who has been the source of major controversy.[[note]]He had done a previous live show from Chicago, which resulted in riots that culminated in several million dollars of property damage and a couple dozen people being arrested for assault.[[/note]] He's scheduled to do a live broadcast from a midtown theater. Frank is faced with two options: honor Swint's rights to assembly and free speech and risk a riot breaking out, or fall in line with Mayor Carter Poole and Reverend Potter and cancel the show completely. Frank decides to guarantee that the show can technically go on, but notes that Swint's contract dictates that he have a police security detail during the broadcast. Frank plants the detail ''inside'' the theater and staffs it entirely with non-white officers under the command of a [[ScaryBlackMan large black sergeant]].
** See also the fourth bullet under ScrewTheRulesIHaveConnections above.
** Two in "Devil's Breath":
*** Officer Peter Grasso, while off-duty, stops an armed robbery in progress. At first he is an hero, but then gets caught receiving breath mints from Jamie to cover up the fact he'd been drinking. So he now is in trouble for pulling his gun after drinking and failing a breathalyzer test, which could mean termination (even though he didn't fire a single shot). Frank is advised to stay out of it. Instead [[spoiler: he calls a press conference and announces that Grasso will face a month-long suspension plus a year of probation, but he gets to keep his job. He also makes it clear he's punishing the officer only because the regulations require it and that he'd work the streets with him any day of the week.]]
*** Nicky leads a demonstration against her schools policies regarding random, unannounced searches of lockers without consent from kids or parents, and Erin's caught between wanting to support Nicky against threats of suspensions for the protest and the fact that, legally, the school does have the right to do so. [[spoiler:In the end Nicky inadvertently gives her the third option by holding the demonstration, key point, ''after hours and across the street from campus''. The principal threatens to suspend the lot of them but Erin walks up and shuts her down by invoking the First Amendment.]]
** In "The Extra Mile," Erin is dealing with a guy who refuses to testify against the man who killed his cousin. Said guy flees out of fear of retaliation, since there are two options: testify and get targeted, or not testify and let the killer walk. Erin takes a third option: put said witness in a jail cell next to the killer's cell. The killer is then caught and recorded threatening the witness. Thus, their killer incriminates himself on tape and their witness doesn't need to testify, and he doesn't fear retaliation because, as far as the killer's gang is concerned, the guy never cooperated.
** In "Power of the Press," Erin's schoolmate's daughter is raped on campus, and apparently the evidence available is useless because it was withheld by the college. Erin realizes that she can't order the arrest of the rapist since there's almost nothing against him due to the evidence tainting. But she can order the arrest of the dean of students for hindering prosecution.
* TakingTheKids: Erin got Nicky after divorcing her husband, a defense attorney. To this day, Nicky is convinced on some deep level that defense lawyers are heroes and [=DAs=] are evil. [[spoiler:Subverted in that Erin didn't ''take'' Nicky. Jack didn't want custody at all and Erin had to insist that he take partial custody. Even then he's an [[DisappearedDad absentee father]].]]
* TakeThat: One episode sees Jamie and Edie working security on the set of a cop show due to the NYPD TV and Film Unit being stretched. The show is apparently called ''Dempsey & Kaine'', and based on Edie's description of it as a cop show with two female detective leads, with decent actors but terrible writing, is probably meant to be a jab at ''Series/RizzoliAndIsles''.
* TapOnTheHead: Oh, right -- Danny doesn't appreciate people pointing guns at Jackie, either.
-->'''Perp:''' I give up.\\
'''Danny''': Too late. [''punches his lights out'']
* ThatWasTheLastEntry: While listening to Joe's old [=iPod=], Jamie uncovers a recording of his late brother preparing to infiltrate the Blue Templar.
* TherapyIsForTheWeak: Frank sourly tells his shrink that Reagan men don't go for prescription drugs. Or shrinks, for that matter.
* ThirdPersonPerson: In "Knockout Game", Danny and Baez seek out information about who might be behind the most recent incident -- an attack on a pregnant woman whose fetus subsequently died -- from a confidential informant he calls "Third Person Thorpe", who [[VerbalTic speaks just like his nickname suggests]].
* ThreeSuccessfulGenerations: Jamie, Danny and Frank embody this for different "generations" of police work: rookie patrol, experienced detective, and veteran brass. Add Henry, and you've got a fourth generation added on with "retired brass".
* ToBeLawfulOrGood: There are occasions where the cast must face this sort of dilemma.
** "The Poor Door" sees a notable case: Louis Weems, a former drinking buddy and partner of Gormley's, has been found to be engaging in shady real estate investments. When Frank informs Gormley that he is the one who gets to decide whether to retain or terminate Weems, Gormley ultimately decides to let Weems keep his job, with the agreement that he won't be so lucky if he's caught cutting corners again.
* TooDumbToLive: More then one nemesis. For example, unrepentant serial rapist Dick Reed [[spoiler:decides, upon release, to go after Erin, who is not only a DA but has four cops in her immediate family. Two of said cops being the police commissioner and one of the best detectives in the entire department]]. Why he thought this would end well for him is anyone's guess, when Frank shows up and shoots him.
* ToyotaTripwire:
** A perp decides to rabbit and escapes on a scooter. He nearly mows down Danny, but doesn't quite clear Jackie's front bumper. Ouch.
** Reused in "Occupational Hazard" when a motorcycle gangster and his girlfriend who vandalized Erin's apartment and attacked one of her colleagues (which they were trying to frame a rival gang for) try to flee from an ESU raid, driving along the sidewalk and through traffic. Danny and Maria cut around the block and the gangsters run into the passenger side tire and go flying.
** An actor doing a ride-along with Danny stops a fleeing suspect with the car door and nearly gets shot in the process. However, once he's in custody the suspect thinks it's cool he got stopped by a famous actor.
* TranquilFury: Frank. ANY time Frank gets pissed, he doesn't really act any different, but all of a sudden, Danny isn't the scariest Reagan in the show anymore.
* TurnInYourBadge: When cops use lethal force or are involved in a highly controversial incident, they are 'placed on modified assignment'. That is, they are relieved of their shield and on-duty gun, and are placed on desk duty. Of the regulars, Danny gets subjected to this the most when his actions get him in hot water, including a few PoliceBrutality cases (some legit, some false), and FriendlyFire incident in season 2. In the season 4 finale, he's placed on modified assignment so as to be kept from uncovering high-level corruption. It's lampshaded and subverted in the season 7 premiere, when Gormley is sent to inform Danny that a new inquiry has been opened into his shooting of serial killer Thomas Wilder. Danny immediately produces his shield and gun to Gormley, only for Gormley to inform that he's not being place on modified assignment this time around.

[[folder:U-Y]]
* UncomfortableElevatorMoment: Frank has one in "The Job" when he's paying a secret visit to a psychiatrist.
* VigilanteMan: Episodes like "Samaritan" and "Old Wounds" have [[WellIntentionedExtremist Well-Intentioned Extremists]] killing KarmaHoudini criminals.
* VowOfCelibacy: When the Reagans' deceased longtime priest comes up for canonization, Frank discovers that Father Bill had a long-term romantic relationship with a woman, but as far as anyone can tell it was never actually consummated in deference to priestly vows. Frank compares this favorably to a saint of a previous century who took part in what would be considered genocide in the present day, and concludes that "the Catholic church could do a lot worse than 'Saint Bill from Brooklyn'."
* TheWarOnStraw: The show does not take a romanticized view of the NYPD Commissioner or his office. Frank has butted heads with protesters and union reps. [[ZigZaggingTrope Zig-Zagged]] in "Leap of Faith", which seems to portray the archdiocese as a standard CorruptChurch shielding a [[SinisterMinister anarchist priest]]. Though Frank initially opposes his nomination for sainthood, after performing his own investigation, he decides things weren't so black and white in the Vietnam days. He even comes to the priest's defense when the archbishops show signs of buyer's remorse.
* TheWarOnTerror:
** Mentioned from time to time. Frank was a 9/11 first responder and saw the towers go down; he suffers from SurvivorsGuilt as a result. He also has a [[BerserkButton peeve]] about people exploiting the tragedy to further their careers. Danny was a Marine who fought in Fallujah.
** In one early episode, the NYPD is put on high alert for a bomb threat by ''homegrown'' Islamic terrorists.
** In "Hall of Mirrors" an undercover cop who infiltrated a terrorist cell is shot in a drive-by. It turns out to have not been related at all to the cell infiltration but to a love triangle.
** In "Moonlighting", Frank broods over a quote from Donald Rumsfeld regarding the Iraq War ("the [[http://en.wikipedia.org/wiki/There_are_known_knowns known unknowns]]").
** In "Friends in Need," Frank acknowledges the issues that come up with intelligence gathering while hosting a number of top British police officials, bringing up the November 2015 Paris terrorist attacks in doing so.
* WeUsedToBeFriends:
** In "Family Ties," it turns out that Jackie and her high school friend, Anna, ended up on opposite sides of the law. Jackie became an NYPD detective, and Anna got knocked up by a Russian mobster at age 16.
-->'''Jackie:''' What happened to you?\\
'''Anna:''' [''icily''] I grew up.
** In "Ties That Bind," Danny's childhood friend Mickey Patrick pays him a visit. At one point, while Mickey and his wife are bonding with Danny and Linda, Danny sees a surveillance truck outside seemingly taking photographs of the house. The next day, he learns from an OCCB investigator from that Mickey is under investigation as a suspected mob associate. Danny ends up being torn between his obligations to enforce the law and loyalty to Mickey. Once he gets Mickey arrested, he must move to keep him from being targeted for retaliation from the mobsters he works with.
* WhamEpisode: The last two episodes of Season 3, featuring a plot revolving around the Bitterman Housing Projects '''definitely''' count as this trope, as they prove to be a game-changer for the series. Much later, the characters refer to the Bitterman Housing projects again in the context of continuing to make life better there.
* WhatDoYouMeanItsNotForKids: An in-universe example. One weekend, while watching Danny's sons, Henry and Frank have tickets to a Broadway play. It's about Christianity and bringing it to Africa, or so Henry heard. ... The play is ''Theatre/TheBookOfMormon'', by Trey Parker and Matt Stone.
* WiseBeyondTheirYears: Nicky pushes this trope hard.
* WoobieDestroyerOfWorlds: "Under the Gun"'s killer is [[spoiler: a CrusadingWidower who finally snapped after losing both his wife to medical malpractice and his resulting lawsuit via MiscarriageOfJustice.]]
* WorkingTheSameCase: Occasionally shows up.
** In "Inside Jobs," some rats are set loose at a society gathering that Erin is attending, hosted by a socialite who calls herself "Goddess". That same night, Danny is called in on a man who was beaten up then tossed out of a car, with a dead rat in his pocket. As it turns out, the two incidents are linked as the beating victim was the one who set loose the rats at the reception.
** "Rush to Judgment" does a variant: the cases are not the same, but they both originate from the same event. At an anti-NYPD protest led by Reverend Potter and civil rights attorney Jerry Guerrero, Jamie is working security, and attempts to protect a mother and child from an inattentive biker, causing the biker to crash and get injured. Conflicting accounts, as well as Potter's smear campaign, forces Frank to hand the case over to Internal Affairs. At the same time, a woman and crowd supporter claims that Guerrero raped her; he denies this. Thus Danny and Baez are assigned to investigate that matter. They uncover that she faked the claim so as to get revenge for a previous problem the attorney was involved with. To fix things, Frank visits Potter and offers to help exonerate Guerrero if the police are given access to witnesses that clear Jamie of his own problem.
** "Worst Case Scenario" has Frank convinced that terrorists might be coming to New York City to launch an attack. His claims seem confirmed when Jamie and Edie take a report from a waitress at a club who claims that she heard a regular customer speaking terrorist-like language. Coincidentally, an Arabic-speaking man runs into Danny and Baez on the street, frantically claiming that his neighbors possess bombs. Danny's lead and Jamie's lead are the same case.
* YouAreNotAlone: Frank reminds Danny of this at the end of "Silver Star," when Danny muses on how he could have ended up just like the victim, a homeless vet.
* YouShouldHaveDiedInstead: The wife of a slain informant discovers that Erin was the one pulling his strings. "So because ''you'' suck at your job, ''I'm'' a widow, and my kids don't have a father." [[spoiler: Of course, this is rendered moot when it turns out, the wife was cheating on her man with someone he was investigating, who was the ''actual'' killer, and that it was ''the wife'' who blew his cover, if unintentionally, not Erin.]]
* YourCheatingHeart: In "Whistler Blower," Erin's informant is murdered, while spying on a white collar criminal -- the same criminal who is [[spoiler: sleeping with the informant's wife.]] So much for wearing a wire.
-->[[spoiler: Mrs. Milo]]: [To Erin] "I don't know what fancy place you come from, but from where I come from, there is ''nothing'' worse than a [[TheInformant rat!]]"
* YourDoorWasOpen: In "Occupational Hazards," Erin is dealing with intruders who have been rearranging things in her apartment. Danny, not happy that she chose to call 911 instead of just calling him to look into the matter, spooks her by hiding behind her open door when she comes into her office.
