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 cop 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 live 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 leader, 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 the city of New York.

''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:

* 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.
* 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.
* AlternateHistory: As far as the NYPD is concerned since 9/11 and the 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 Walter Kelly. In 2014, during the show's fifth season, Mayor Bill de Blasio appointed former NYPD Commissioner William 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]]. 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.
* 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 wife]].
* 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]]Slightly different wording as far where the words "Police Department" and "City of New York" go[[/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]]. Averted beginning in the first episode of season 3, when the show got the approval to use replica cars with the correct patrol car font and emblems with the correct 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.
** The NYPD Major Case Squad is depicted as operating at precinct level. 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=].
* 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 fiancee 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.
* 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.
* 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. 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]].

* 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. One episode dealt with Jamie temporarily partnering up with such a cop because the rest of the department shunned her for being a "rat" (her partner killed a suspect in custody using an illegal chokehold and she admitted she saw him do it with a little prodding from Frank) and when they were caught up in a shoot out '''nobody''' came to be their back up, which results in Jamie giving his whole precinct a deserved WhatTheHellHero speech. 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 their initial hiding place, they hide the witness at Jackie's apartment, without telling anybody this. Danny, unable to find the mole through background checks, decides to sniff out the mole. To do so, he gives the witness's address out to the task force, hoping that the mole will react accordingly by sending hitmen to kill the witness. Sure enough, two hitmen go to the apartment, break down the door, and promptly come face-to-face with an ESU team planted inside, who kill one and capture the other. Danny had deliberately fed the mole (who as it turns out is one of the DEA agents on the taskforce) a false address.
* 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?
* BestServedCold: The Phantom arriving 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 police.
** Billy Flood attempts to draw a sniper's fire in "Critical Condition." Danny [[AvertedTrope thwarts it]] by pushing him away.
** The Phantom pulls the old "YouWouldntShootMe" trick. He ends up pancaked [[CarCushion on top of a car]].
* 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.
* BlackBossLady: Danny's new supervisor in season 5.
* BlackDudeDiesFirst: The undercover cop in "The Life We Chose."
%% * {{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".
* BloodSpatteredInnocents: In "Whistle Blower", the titular 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: Renzulli. "'Rhetoric?' I'm [[ExpospeakGag not familiar with the vernacular]]."
* BreakTheCutie: Happening to Jamie more and more often.
** His first kill in the line of duty turned out to be a case of 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.
* CaliforniaDoubling:
** Averted. The show is set and filmed on-location in UsefulNotes/NewYorkCity.
** The pilot had some interior scenes that were shot in Toronto, although exteriors used New York City proper.
* CallBack: Frank and Jamie's conversation while fishing in Episode 1 of Season 2, a callback to the pilot.
* TheCameo: Frank grudgingly attending a performance by Tony Bennett and Carrie Underwood. (To promote Bennett's second duet album)
* 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 sister of the murder victim.
* ChristianityIsCatholic: Justified. At least ''some'' are after all. They're also Irish.
* CitizenshipMarriage: {{Reconstructed}} in "Exiles". Jamie and Eddie 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.
* ClintSquint: How Danny sizes criminals up.
* CombatPragmatist: Jamie's temporary partner Luisa Sosa in "Critical Condition". 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 there criticisms are unfounded or wrong thanks to Frank.
* ConflictingLoyalty: Jamie is asked by the FBI to spy on a secret society for them that might include Danny.
%%* TheConsigliere: DCPI Garrett Moore.
* ConverseWithTheUnconscious: Frank and his [[OldFriend old squadmate]], John [=McKenna=], just as he's taken off of life support.
* CopKiller:
** In "Officer Down" a patrol officer is mortally wounded 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]], to the point that when [[TheCoronerDothProtestTooMuch one cop killer got shot twice in the back by a mobster, 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.
** In "The Bitter End" Jamie Reagan and his partner Vinny Cruz are lured into a housing project by a Latino gang with a beef against the NYPD. It's an ambush, [[spoiler:and Vinny is fatally shot]]. End of the next episode, what seems like half the NYPD storms the place and makes over 40 arrests on various charges, including [[spoiler:Vinny's murder]].
* CoolShades: Frank Reagan sports these.
* CowboyCop:
** Danny Reagan 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]].
* CrazyJealousGuy: When Bianca hits on Jamie, he suddenly finds himself afoul of her jealous ex ''and'' her mobster brother.
%%* CrimeTimeSoap
* CutHimselfShaving: In "Family Ties", a Russian gangster 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.
** Newly promoted Chief Dino Arboghast jumps from OCCB Chief to Chief of Department. (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's office)
** Sidney Gormley runs Danny's department, a job which harries him to no end.
%%* DatingCatwoman: Erin has a habit of this.
* DeathByOriginStory: Joe Reagan.
%%* DiabolicalMastermind: The Phantom.
* DeathSeeker: Sergeant Mabrey in "Unsung Heroes". It starts with an incident with a barricaded suspect; in said incident, Mabrey, rather than wait for the [[SWATTeam ESU]] team and hostage negotiator (as is NYPD protocol and what [[ByTheBookCop Jamie]] suggests), storms the house and inadvertently endangers the hostage in subduing the hostage-taker. It's quickly clear to Gormley 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, 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).
* DinnerAndAShow: What the family meals sometimes turn into.
* DirtyCop: Danny discovers that one of the would-be bank robbers is an ex-cop, Billy Flood.
* DirtyHarriet: One episode has Jackie going undercover to catch a killer with a predilection for webgirls.
* 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, Renzulli is hailed as the hero to protect the undercover sting that Jamie is engaged in. [[spoiler:Played with a little: Frank gives Jamie the medal he deserves privately later.]]
* EngineeredPublicConfession: The killer in "Hall of Mirrors." One wiretap later, and he's toast.
* EnlightenedSelfInterest[=/=]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]].
* EvenEvilHasLovedOnes: The theme of the episode ''Brothers''.
* 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"?
* ExternalCombustion: The fate of a Russian florist who [[HeKnowsTooMuch knew too much]].
* FakeGuestStar: Gregory Jbara as Garrett Moore. He's in pretty much every episode, and often gets more screen time than some of the main cast.
* FalseFlagOperation: Reverend Potter had one of his friends call in a fake armed robbery at his church and had his men assault the two responding officers 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 : Do you have to ask?
-->'''Frank:''' 271 line of duty deaths since I joined the force.
* FencePainting: In "The Uniform," Jamie is stuck doing this 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.
* FoodSlap: Danny gets a Caesar salad to the face while cornering a perp at his day job -- a short order kitchen.
* 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.]]
* FriendlyEnemy:
** Henry and Happy Jack, a retired mobster; in the GoodOldDays they considered each other as {{Worthy Opponent}}s.
** Frank paying a condolence call on a grief-stricken mafioso who [[NotSoDifferent lost his son]].
* FromTheMouthsOfBabes: What the Reagan children 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]].
* 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."
* GroinKick: 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.
** Interestingly, 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."
* HelloAttorney: Erin Reagan-Boyle. And Charles Rossellini, to be honest (hey, it's Bobby Cannavale).
* HollywoodHeartAttack: Poor Henry is hit with one on Thanksgiving. You think that's going to stop Henry Reagan from [[{{Determinator}} having dinner with his family?]] Ha!
* 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, Sosa, stake out a park bench and wait for someone to take a bag of stolen goods left 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's 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, it's a federal crime to rob a bank, which includes any crimes committed during the course of that, 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.[[/note]]
** In "Unwritten Rules", police detective 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 the suspect there's another witness against him, and offer him a plea deal where he'd only do seven years in prison. Danny then "let's 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.
** "Justice Served":
*** Its 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 party to it). Later on it turns out that Gallo knows the details of the contract killing his client ordered, which he gives to 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.
*** In the same episode, 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 who's complaint they're arresting him on to begin with, 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).
*** On a side note, it's very unlikely Danny, a homicide detective, would be allowed on the jury in a murder trial by the defense (though he ends up on their side).
** 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. However, 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.
** Danny Reagan is known to have hotheaded tendencies to the point that he's gotten in trouble for roughing up suspects. In real life, he would not be allowed to work with the public because of these tendencies. Even with his father being the active commissioner, Danny could easily become a liability for the NYPD if someone sues him for emotional distress/police brutality/whatever.
* 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.''
%%* 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.
* 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", The Phantom takes Barber's family hostage to get him to show himself.
** A drug cartel kidnaps ''Linda'' to try to keep Danny from testifying. [[BerserkButton Big mistake.]]
* IJustShotMarvinInTheFace: {{Invoked|Trope}}. In "This Way Out" some gangbangers trick a mentally retarded kid from their housing project into shooting Mayor Poole by telling the kid it was a game.
* ILoveYouBecauseICantControlYou: Thief extraordinaire Jacob admits he's pursuing Erin because he "loves a challenge."
* 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?"
%%* IncorruptiblePurePureness: Jamie has shades of this.
* InformedAttribute: In "Black and White", 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.
* InternalAffairs: We've seen two recurring-role investigators so far. BOTH have been revealed to have been crooked. On the other hand we have Det. 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-sex 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 her opposite number in the Case of the Week. [[spoiler:End of the episode, he asks her out to dinner and she accepts.]]
* ItsPersonal:
** 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 case of Raymond, the 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 was shot and killed by a burglar.
* ItRunsInTheFamily: Nicky browbeating Erin into letting her stay out until 11:00 (Grandpa 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."
* 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.
** Erin is a Columbia graduate, and as of the end of Season 5, it seems that her daughter Nicky will follow in her footsteps.
* JerkWithAHeartOfGold: When 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 billed for it... totaling all of $1.
* {{Joisey}}: Inspector General Kelly Peterson from Season 4 is originally from New Jersey ([[{{UsefulNotes/NewJersey}} Newark]], to be exact) 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).
* 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). 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]].
** "Frank Weller" 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]].
%%* KnightInShiningArmor: Jamie.
%%* KnightInSourArmor: Danny.
* LawEnforcementInc: A shady private security outfit has approached Henry with a job offer. So far, he's turned them down.
* LetMeTellYouAStory: [insert Grandpa Henry moment of badassery here]
* LoanShark: Sgt. Renzulli gets in deep from betting on horses. Frank bails him out, with the explicit proviso that it's one-time only.
* 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.
* 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.
* 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: Jamie going undercover to befriend a hotshot mafioso. In Season 2, he poses as a stockbroker to gain access to the mob's investment firm.
* 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.]]
* MakeItLookLikeAnAccident: Perp not talking, huh? Hey, let Danny have a look at that cool katana on the wall, would ya?
-->'''Danny:''' Okay. Here's how my testimony's gonna go. "The suspect grabbed a sword down 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."
* MarriedToTheJob: Danny, to Linda's resentment.
* 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.
--->'''Reagan:''' [[ParentheticalSwearing I have to take this call]], Your Honor.
** Subverted by his successor, Mayor 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. Three guesses who the family's last name was inspired by.
%%* MouthyKid: Nicky has her moments.
* TheMentor: Sergeant Renzulli, Jamie's training officer.
* MirandaRights: Used on occasion like 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.]]
* MistakenForCheating: Garrett interprets Frank's strange absences (at the psychiatrist's office) for 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"
* MysteriousPast : Both Danny and Grandpa Henry.
* 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 one episode 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 interviews 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.
* NewMeat: Jamie. He's slowly leveling his badass and becoming 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...
* NoBadgeNoProblem: In "The Uniform" Danny's Case of the Week involves an auxiliary officer, a part-time patrolman who is not issued a gun and is usually supposed to call in the real cops. The auxiliary in question brought along his own gun and fired on a suspect. [[spoiler:It was eventually ruled a good shoot, and the auxiliary even got into police academy later.]]
* 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.
* 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.
* 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 [[spoiler: Linda is shot by a gangster]] and the family has still manages to have Sunday dinner together thanks to Skype (with [[spoiler: Linda and Danny "joining" them from Linda's hospital room]], and eating a meal there, while talking to the rest of the family, who are also eating at home).
* OrderVersusChaos: A subtle theme throughout the series, with [[ByTheBookCop Frank and Jamie]] disagreeing with CowboyCop Danny.
* 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. Season two's Carter Poole is a Mayor Personable/Mayor Minority twofer.
* 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 was 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.
** 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 was Jamie.
** Henry causes a public stink when a recording of one of his old war stories goes viral: 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 but Henry reveals that the cop was Frank.
* 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: An obsessive-compulsive woman 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 one episode. An Argentinian diplomat's son is protected by 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 ([[spoiler: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 somewhat shocking]] 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]]. [[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?
** Maria 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.
** A criminal chased by Danny into an apartment building ends up jumping from a third-story window after Danny gives him the idea with an empty threat. He immediately starts screaming "police brutality." With no one able to back up Danny's claims, especially given his history, he becomes the target of Rev. Potter, an Al Sharpton like expy with political ambitions and a beef with the NYPD. 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, the reverend 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 the reverend is also arrested for his part in all this.
* 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."
** A pair of junkies holding up an immigrant family ("Parenthood"). "I know you '''people''' don't use banks. Where's the money, ''chica?''"
* PompousPoliticalPundit: The borderline white-supremacist radio host who [[spoiler:tries to]] make a live broadcast from a New York theater.
* PrinciplesZealot: Erin, the daughter is an assistant DA 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.
* 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.]]
* PromotedToOpeningTitles: Jackie in mid-Season 1; Linda and Nicky in Season 2.
* PulledFromYourDayOff: Poor Danny once catches a homicide right when he and Linda are about to go out to Long Island for the weekend. 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:
** Reed tries on Frank, holding Erin's 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.
* PutOnABus: Mayor Poole does not appear much in season 3, as his actor was a series regular on ''Series/{{Arrow}}''. He returns for the last two episodes.
* 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 assaulted two of his officers during the ColdOpening; 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 Reagan's case of the week involves a father seeking vengeance for his daughter, dead of an apparent 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 beats the shit out of 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.
* RealitySubtext:
** Several episodes highlight levels of distrust between the police and the black communities, and were produced around the same time that the "Black Lives Matter" movement - started in the wake of the deaths of Michael Brown and Eric Garner - took off.
** Some elements of "Forgive and Forget" and its lead-in "Custody Battle", specifically an officer using an unauthorized chokehold on a suspect that led to the suspect's death, invoke the controversy against the NYPD for the death of Eric Garner, himself the victim of an unauthorized chokehold.
* RippedFromTheHeadlines:
** The second episode of season 1 involves a good Samaritan who shoots 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. It brings to mind Bernhard Goetz, the "Subway Vigilante" who shot and wounded four men who tried to mug him in December 1984, and was acquitted of all charges except for carrying an unlicensed firearm.
* ARealManIsAKiller: The letter of the trope is averted rather thoroughly by leaving Jamie Reagan'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.
* 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."
* [[ReassignedToAntarctica Reassigned to Staten Island]]: When Frank's position as Commissioner seems to be at stake, Gormley dreads the possibility of getting transferred to Staten Island. Likewise, in "Stomping Grounds," when Jamie and Edie get a new sergeant who has a habit of hitting on women in the 12th precinct, Jamie gets rid of him by telling him to put in a transfer to Staten Island.
* ReformedCriminal: The barber from "The Life We Chose."
* 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.
%%* 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 [[GoodOldDays 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.
* RogueJuror:
** Unusually done in the fourth season episode "Justice Done" when Danny Reagan, a detective, 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. 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."
* TheScapegoat: After Danny's wife Linda chews him out over not mowing the lawn, the ''world'' becomes this trope. Culminates in a still-agitated Danny gunning down a fellow cop. ("Friendly Fire")
* ScrewTheRulesIHaveConnections:
** Inverted in "Parenthood," when the Mayor's 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 Jamie, of course. With his family connections, he could have made Detective by now.
** When Jamie is accused of undue force, 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 smark 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 when Jamie arrests the previous mayor's daughter for smoking pot. She tries to invoke this, but 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 an American during the tour). [[spoiler:Frank talks a contact into getting the New York Philharmonic to hire her, and his opposite number at State, the episode's SympatheticInspectorAntagonist, expedites a work visa.]]
* 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: As Jamie picks up his brother's old case, Sonny Malevski keeps reappearing to turn up the heat.
* ShootHimHeHasAWallet: Danny shoots a man who seems to be holding a gun. It turns out the guy was an off-duty police officer and was about to show them their badge. Danny is in serious trouble while Internal Affairs investigates whether it was an honest mistake or negligence.
* ShootTheHostageTaker: At the end of the episode "Re-Do", a serial rapist takes Erin hostage within sight of Frank, and tells him to [[PutDownYourGunAndStepAway put down his gun and step away]]. Or that was the plan, anyway: [[PapaWolf Frank puts a .38 round]] [[BoomHeadshot through his forehead]] [[KilledMidSentence before he can finish the sentence]].
* 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: Dick Reed the serial rapist obsessively plays a vinyl record of "Ave Maria."
* TheSouthpaw: Danny shoots left-handed.
* StrawmanPolitical: The show is 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.
* StrawmanU: Much to Niky's displeasure she finds out that Columbia falls under this this when radical left students protest Frank while he's giving speech, to the point he's driven off the stage after five minutes. Poor Nicky's in tears throughout the whole thing.
* StopOrIShootMyself: In the Season One finale, [[spoiler: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, an ex-con Danny put away takes his partner, Jackie, hostage and ties her to a bomb in order to draw Danny out.
* 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," Frank gets word that the ''New York Daily News'' is about to run a spread about how a veteran Narcotics detective has been photographed with a brand-new red Ferrari that costs about the equivalent of three years' detective salary; a detective who happens to be a drinking buddy of Gormley's. Turns out the guy is doing shady real estate investments into buildings that he's done 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.
** Jamie had a childhood habit of swallowing things. Amongst the list of things he swallowed was an actual key, which opened the Reagans' liquor cabinet.
* TakeAThirdOption: Frank is really good at finding the third option in ToBeLawfulOrGood dilemmas in the last few minutes of the episode.
** Faced with public outcry against a brutal dictator coming to New York for medical treatment, [[spoiler:Frank has the police protect him 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]].
** Faced with a [[PompousPoliticalPundit white supremacist radio host]] making a live broadcast from a New York theater, [[spoiler:Frank ensures the show can technically go on, but puts the man's police protection ''inside'' the theater and staffs it entirely with non-white officers led by a [[ScaryBlackMan VERY large black sergeant]]]].
** See also the fourth bullet under ScrewTheRulesIHaveConnections above.
** When an off duty police officer, who has had a few drinks, stops a robbery at first he is an hero - then he is in trouble for pulling his gun after drinking. Frank is advised to stay out of it. Instead [[spoiler: he calls a press conference and announces the man will be slightly punished, 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.]]
** Frank's not the only one. In one episode 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.]]
* 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, her father didn't want custody at all and Erin had to insist that he take partial custody. Even then he's an [[DisappearedDad absentee father]].]]
* 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.
* TheMainCharactersDoEverything: More like "The Main Characters All Do the Same Thing". Generally speaking all the cases on the show are found by Jamie and his partner, investigated by Danny and his partner, and prosecuted by Erin and her party.
* TherapyIsForTheWeak: Frank sourly tells his shrink that Reagan men don't go for prescription drugs. Or shrinks, for that matter.
* ThreeSuccessfulGenerations: Jamie, Danny and Frank embody this for different "generations" of police work: rookie patrol, experienced detective, and veteran brass. A fourth generation is added on with "retired brass".
* TooDumbToLive: More then one nemesis.
** Unrepentant serial rapist Dick Reed [[spoiler:attacks Erin, who is not only a DA but has four cops in her immediately 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.
* 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 try to break out of an NYPD arrest, 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.
* VigilanteMan: Episodes like "Samaritan" and "Old Wounds" have [[WellIntentionedExtremist Well-Intentioned Extremists]] killing KarmaHoudini criminals.
* VowOfCelibacy: When the Reagans' deceased longtime minister 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's 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 entire department goes 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.
** 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]]").
* WeUsedToBeFriends: Jackie and her high school friend, Anna, ended up on opposite sides of the law.
-->'''Jackie:''' What happened to you?\\
'''Anna:''' [icily] I grew up.
* 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 was about Christianity and bringing it to Africa, or so Henry heard. The name of the musical? ''Theatre/TheBookOfMormon''.
* WiseBeyondTheirYears: Nicky pushes this trope hard.
* WoobieDestroyerOfWorlds: "Under the Gun"'s killer is [[spoiler: a CrusadingWidower who snapped after losing his wife to medical malpractice, and losing his resulting lawsuit by MiscarriageOfJustice.]]
* WorkingTheSameCase: Whenever a case Danny is working ends up crossing paths with whatever Jamie is up to.
* 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!]]"
