->''"You see, Jules shot an off-duty rookie last year. 24 years old. Kid had a baby on the way. But good drug dealers can afford good lawyers, so Jules walked. I had been tracking him for weeks, just waiting to get the guy alone. And there he was, walking out of a bodega, with not a care in the world. No protection, either. He saw me. He knew why I was there. I could see it in his eyes. So I smiled at him. Just before I put two in his chest. ... Guy got what he deserved, and you want to know how I've been sleeping? Like a baby."''

A staple of the CriminalProcedural when the writers want to create a "This Time, ItsPersonal" episode. Pretty much ExactlyWhatItSaysOnTheTin: a criminal kills a cop and the dead officer's colleagues have to avenge him. These episodes frequently end with PoliceBrutality, as cop killing is a rather serious business. When the cops find the cop killer, they don't treat him very well. Not to mention that they're more likely to [[MakeItLookLikeAnAccident have "accidents" or be "driven to suicide" at some point between arrest, trial, and imprisonment]]. Conversely, a cop killer will likely be [[VillainCred regarded as particularly notorious by fellow criminals]].%%Do not hotlink SeriousBusiness from here. That's misuse.

If the criminal is purposely going after cops who previously arrested him, this can overlap with RageAgainstTheLegalSystem. Other times, cops may be killed in the line of duty [[CrimeOfSelfDefense by trigger-happy criminals]]. Of course, they're in particular danger if they're [[{{Retirony}} three days away from retirement]].

While this is often a villain trope, there are cases that this trope may be applied to an AntiHero or a vigilante (particularly if the character suffered some form of PoliceBrutality that would result in the AntiHero or vigilante hunting down cops as well). If TheBadGuysAreCops this may be one way for them to meet their fate. Still, it's very rarely condoned, if ever; killing a representative of law and justice is generally agreed to be something of a MoralEventHorizon, [[AndThatsTerrible for obvious reasons]].

The [[InvertedTrope inverse]] of KillerCop, a cop who is a murderer, although in some cases they do overlap. See also PoliceBrutality and PayEvilUntoEvil, possible reactions by the police when they find the cop killer.

[[folder:Anime and Manga]]
* This was a subplot in ''Anime/DarkerThanBlack'' when Huang's old public security partner Isozaki was killed [[spoiler:by Shihoko Kishida under orders from Syndicate leaders in order to prevent an operation from being compromised]].

* In ''Anime/GhostInTheShellStandAloneComplex'', a plainclothes officer working the Laughing Man case was killed in what appears to be a car accident. Until [[spoiler:Section 9 learns that the accident was engineered by the bad guys in the first season in order to prevent another investigation of the case.]]
* Throughout the ''Manga/BloodyMonday'' manga, several police officers are killed via virus infection or from shootouts by the bad guys.
* The assassin squad "Orchestra" in ''Manga/{{Jormungand}}'' are notorious for killing police officers in their line of work.
* In ''Manga/{{Jiraishin}}'', it happens a lot with police officers being killed by determined criminals and assassins. The following are examples of police officers being targeted directly as the main plot in various story arcs.
** Kyoya Iida's first partner, Tsuyoshi Yamaki, is shot to death by an illegal immigrant from China as he tried to stop an assassination attempt at a local bar.
** Lin Fei, the wife on Taiwanese criminal Fan Tiamin, recruits a Taiwanese hitman to assassinate police officers throughout the Greater Tokyo Area until the Tokyo Metropolitan Police agrees to send the corpse of her sister back to Taipei instead of having it buried in Tokyo since it's against their Taoist beliefs.

* Happens in ''Manga/DeathNote'' when Light begins to target law enforcement officers trying to solve the deaths perpetrated by the Death Note. If Light didn't cross the MoralEventHorizon earlier by killing Lind L. Tailor because of an insult to his {{Pride}}, he definitely crossed it here, JumpingOffTheSlipperySlope and establishing himself as the VillainProtagonist of the series.
[[/folder]]

[[folder:Comic Books]]
* ComicBook/{{Batman}} has dealt with a few:
** Wrath is an EvilCounterpart of Batman who specialises in murdering law enforcement officials.
** The Hangman from ''ComicBook/DarkVictory'' mostly targeted cops, [[spoiler: though [[SamusIsAGirl Sofia]] [[ObfuscatingDisability Falcone]] also made an attempt on Batman and killed her brother, Alberto, with her ultimate target being Two-Face for [[YouKilledMyFather killing her father]].]]
** Among the victims of the Joker were police officers including a SWAT team in ''ComicBook/{{Knightfall}}'' and Commissioner Gordon's second wife, Sarah Essen, at the end of ''ComicBook/BatmanNoMansLand''.
* ''ComicBook/SinCity'': Dwight and the girls of Old Town kill his ex's abusive ex-boyfriend, realizing too late that he's actually a hero cop. If the body is found, the fragile truce between the corrupt cops and the BandOfBrothels will be broken, and the cops and the mob will be free to take over Old Town and brutalize anyone they please, so they need to disfigure and get rid of it.
* ''ComicBook/JudgeDredd'': The Judges of the Mega Cities, considering they have JudgeJuryAndExecutioner built into their job, already have the authority to pass out sentences as they wish. However, (attempted) murder of a Judge is considered among the most serious offenses and always carries an instant death penalty.
* ''ComicBook/{{Wanted}}'': The members of the Fraternity are entirely above the law. At one point [[VillainProtagonist Wesley Gibson]] goes on a shooting spree in a police station like some unstoppable Terminator-supervillain because he was bored.
* This is the main reason why the titular protagonist of ''{{Empowered}}'' just gets tied up a lot. The majority of mooks, henchmen and lower-tier villains do ''not'' want to get branded as a "cape killer", because it ''will'' drive the rest of the hero community to come after them with extreme prejudice.
[[/folder]]

[[folder:Film]]
* ''Film/LAConfidential'': An ex-cop is killed at a diner massacre. Naturally, the cops go all-out on the manhunt.

* The gangsters in ''Film/ReservoirDogs'' kill several police officers during the heist. At the very end of the movie during [[spoiler:Mr. Pink]]'s arrest (which can be faintly overheard), the cops angrily yell at him if he's a cop killer after shooting him. Mr. Blonde, who's the most psychopathic of them, is unapologetically sadistic about it when he mutilates the captured officer Marvin Nash.
-->'''Mr. Blonde:''' It's amusing to me, to torture a cop.
* The villain's plot in ''Film/ScannerCop'' is to brainwash random people to murder Los Angeles police officers, which he is doing out of revenge for being sent to prison previously.

* In ''Film/TheGodfather'', Michael Corleone has to hide out in Sicily for years to escape retribution for killing a corrupt police captain who was in the pocket of another family.
* ''Franchise/{{Terminator}}'':
** The T-800 in ''Film/TheTerminator'' massacres an entire police station in an attempt to get to Sarah Connor. Radio reports later reveal that quite predictably a nationwide manhunt was started for the mysterious gunman. The LAPD are still looking for the shooter more than ten years later in ''Film/Terminator2JudgmentDay'' to get justice for the officers who were killed on that night.
** ''Film/TerminatorSalvation'' starts with the execution of Marcus Wright. We find out quickly that he killed a cop.
*** [[AllThereInTheManual Supplemental materials]] enlighten that it was the final result of a drug-fueled PlethoraOfMistakes that also took Marcus' brother (the police killed him, Marcus fired back). Even AfterTheEnd and being reborn by UnwillingRoboticisation, Wright feels he's so past the MoralEventHorizon [[DeathSeeker he deserves whatever he gets]].
** In ''Film/TerminatorGenisys'':

* ''Film/LethalWeapon2'': The South African government drug dealers assassinate several LAPD police officers to make them back off their investigation. Of course this just makes Riggs and Murtaugh more determined to defeat them. Riggs kills the assassin who killed them, and Murtaugh murders the government official who ordered the hit.
* In the Creator/StevenSeagal B-movie ''Film/UrbanJustice'' a vice squad detective is murdered on duty. The department is massively corrupt so his special forces-trained father takes the law into his own hands, [[spoiler:up to and including killing the DirtyCop who pulled the trigger barehanded]].
* ''Film/TheEliteSquad'': When a bunch of crooks mortally wound an off-duty member of the BOPE (the Brazilian equivalent of a SWATTeam and quite the BadassArmy), they have a massive OhCrap moment and rush him to the hospital (where he dies anyway). Captain Nascimento, the narrator mentions that the crooks are clever to be afraid, because BOPE's reaction to such a death would be a no-holds-barred manhunt... which happens on the third act of the movie, with tortures galore.
* In ''Film/NewPoliceStory'', Chan Kwok Wing hunts down a group of heavily armed robbers who don't give a second thought about gunning down police officers. The main bad guy, Joe, is motivated to do this [[spoiler:because he was physically abused as a child by his police officer father, who had gained a high-ranking position by the time the movie begins.]]
* In ''Film/DriveAngry'', Piper killed two policemen who were unknowingly enlisted by the Accountant, posing as an FBI Agent. When the state troopers put up a road block for Piper and Milton, their leader notes that two of their own have been killed and in order to get even instructs the cops to aim for the suspects' heads.
* ''Film/{{SWAT}}'': Alex Montel never actually pulls the trigger on a cop, but two Los Angeles County sheriff's deputies, an LAPD helicopter crew, and one SWAT officer die as a result of his actions and the team considers him no better than the people who ''did'' pull the triggers. And neither does he, apparently:
--> '''Montel:''' American greed. It's so reliable.\\
'''Street:''' ''SHUT UP!'' Another officer's dead 'cause you shot your mouth off.\\
'''Montel:''' That's how I like cops: Dead.
* ''Film/DeathWarrant'': The Sandman has a fondness for killing cops. This drives Burke to hunt him down in the opening for killing his partner, and the other convicts to [[VillainCred admire him]].
* ''Film/{{Mothra}}'': Clark Nelson, murders a policeman while attempting to escape an enraged Mothra.
* ''Film/RoboCop1987'' has Clarence Boddicker, who among his criminal acts (which include robbery, drug dealing, and according to his rap sheet, rape), having killed 32 police officers before killing Alex Murphy. However, his killing Alex comes back to bite him in the ass when Alex is resurrected as the titular cyborg.
* The plot of ''Film/FortyEightHours'' is kicked off by psycho Albert Ganz and his equally vicious partner Billy Bear killing two prison guards to spring Ganz from prison. While hiding out at a hotel, Ganz and Bear ambush and kill two plain clothes detectives, and to show they're not finished with their disdain of law enforcement, later they kill a transit officer in a subway station. One hooker who Ganz roughed up even tells the cops that he seems to like killing cops more then getting laid.
* ''Film/{{Assassins}}'': Miguel Bain is almost casual about blowing away any law enforcement officer who gets in his way. When there's a manhunt underway for Miguel, his rival Robert Rath berates him for being so stupid/psycho to attract attention by killing cops.
* In ''Film/KickAss2'', Mother Russia slaughters ten officers. As a result, the police order a manhunt on all costumed heroes and villains.
* ''Disney/{{Zootopia}}'': [[spoiler:Dawn Bellwether attempts to kill Judy via a frenzied Nick and, for extra mileage, calls in the rest of the police department to watch.]] Too bad the targets had things planned out in advance.
[[/folder]]

[[folder:Literature]]
* ''Literature/{{Discworld}}'' has Carcer from ''Discworld/NightWatch''. He's killed several cops over the course of his career, including at least one who bumped into him by chance while off-duty and didn't even recognize him.
* ''Cop Hater'' is the title of the first ''Literature/EightySeventhPrecinct'' novel. Here, a murderer kills three policemen; [[spoiler:as it turns out at the end, [[SerialKillingsSpecificTarget the third was the true target]], and he only killed the first two to mislead the police into thinking that he's a SerialKiller who targets cops.]]
* ''Literature/InDeath'' series: This has happened a few times, and when it does, you can bet that this a considered a MoralEventHorizon for the cops at least and maybe the reader. This happened in books like ''Ceremony In Death'', ''Survivor In Death'', ''Judgment In Death'', ''Treachery In Death'' and ''New York To Dallas''.
* A variation in ''Literature/PrizzisHonor''. While the police are normally [[CorruptCop totally in the pocket of the mafia]], after a policeman's wife is killed during a hit, they call off their special arrangement until the killer is turned in or killed.
* In the ''Literature/SavannahReid'' mysteries, the bad guy in ''Cooked Goose'' is a cop killer ''and'' a KillerCop.
* In the ''TabletopGame/{{Shadowrun}}'' novel ''Lone Wolf'', deep-cover gang investigator Wolf Larson is listed as a CopKiller as part of his cover identity, to enhance his credibility with the Cutters street gang he's infiltrated. This backfires when he loses contact with his handler and needs to get word to authorities quickly, as he's afraid any other cop he contacts may retaliate against him as soon as they look up his "criminal history".
* ''Literature/TheyTalkedToAStranger'', an "only the names have been changed to protect the innocent" set of case studies of juvenile delinquents of the 1950s. The first case discussed is of "Moustache", who killed an officer while escaping custody. The police were sympathetic to his situation (Moustache was a non-violent offender whose crime was the result of a string of poor decisions bad luck on both his and the officer's part) but that didn't stop them from pulling out all the stops to capture him. He was scheduled to be released sometime in the 1980s, with good behavior.
* Acidbath from ''Literature/{{Worm}}'' was a cop and capekiller with the ability to shoot and turn into acid before getting thrown in the Birdcage.

In ''Literature/IJedi'' he explains to Luke Skywalker that after he caught Bossk, he literally could've frog-marched him into the lobby of One [=CorSec=] Plaza and shot him resisting arrest, and nobody in the building would've batted an eyelash.
* ''Literature/TheRunningMan'': Richards kills three Boston police officers in a gas explosion during his underground escape from the hotel. He already had a target on his head, but now every cop in the city wants his blood.
[[/folder]]

[[folder:Live-Action TV]]
* In ''Series/{{CSI}}'' there are a few notable examples.
** The RedShirt who gets killed when Warrick leaves her alone at a crime scene in the pilot.
** A random officer who's killed outside a burger joint...by another cop who claims it was an accident, but might have had a grudge ([[spoiler: it was dark and said cop was losing his vision]]).
** [[spoiler: Warrick Brown]] was killed at the end of a later season by [[spoiler: [[TheMole The Undersheriff]]]].
** ArcVillain [[DeadlyDoctor "Dr. Jekyll"]] makes his presence known at the end of his arc by blowing away a RedShirt cop with a shotgun and [[HeroKiller severely wounding Nick]].
** A two-episode arc immediately following the "Dr. Jekyll" arc guest-starred Music/JustinBieber as a part of a sibling team of RightWingMilitiaFanatic [[MadBomber Mad Bombers]] that bombed the cop's funeral and (once the big brother was killed) driving the younger brother into a vendetta against Nick.
* ''Series/DueSouth'' begins with the murder of a [[CanadaEh Royal Canadian Mounted Policeman]] in the wilderness of the Northwest Territories. The plot of the pilot episode centers around [[YouKilledMyFather his son]], Benton Fraser ([[InTheBlood also a Mountie]]) , teaming up with a Chicago detective to [[AlwaysGetsHisMan track down the killer]] after he crosses the border into the [[EagleLand United States]]. It turns out the killer was hired by another [[spoiler:Mountie, a close friend of the Frasers, no less.]]
* ''Series/BlueBloods'':
** Joe Reagan, brother to Danny, Erin, and Jamie, was a patrolman who was killed in the line of duty before the series began. Jamie's unofficial investigation into his death forms season 1's MythArc and leads to the unmasking of the Blue Templar, a fraternity of dirty cops in the NYPD.
** 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]]. 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, tries to shoot his way out, and is hosed down with lead by several detectives and an ESU team.\\
\\
While searching for the killer, Danny finds and arrests an accomplice (whose father is a retired NYPD officer), who he takes to a spot on the water, then explains 50 years earlier the man's father took a cop killer to that exact spot, shot him twice in the head and dumped the body in the river. It was ruled an accidental death. Danny then explains the man's father would likely disown him if he killed a cop and was executed in such a fashion. This breaks the man into giving the real killer.
** In "The Bitter End" Jamie Reagan and his partner Vinny Cruz are lured into the Bitterman Housing Projects by a Latino gang with a beef against the NYPD. It's an ambush, and Vinny is fatally shot. End of the next episode, the NYPD, with Mayor Carter Poole's blessing, conducts a massive sweep of the Bitterman Projects, rounding up over 47 members of the Los Lordes organization for various charges including conspiracy to murder Vinny, an assassination attempt on the Mayor (which leaves the Mayor paralyzed and confined to a wheelchair), narcotics possession with intent to distribute, enterprise corruption, racketeering and a number of other criminal offenses.
** Used a little oddly in "Above and Beyond". Steve Tomlin, a detective from Danny's precinct, is killed, and 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). [[spoiler:Turned out the undercover detective's cover was blown when his wife drunk-dialed a number on the detective's contacts list, thinking it belonged to [[YourCheatingHeart the other woman]], when in fact it was a member of the drug cartel her husband was investigating.]]
** The two part season 5 finale concerned the death of recently-promoted Assistant Chief Donald Kent of the NYPD Gang Division, gunned down along with his wife Maggie in a drive-by shooting by members of the Warrior Kings gang. The hit itself was carried out on orders of an incarcerated gang member.
* From the 1960s ''Franchise/{{Dragnet}}'' series:
** {{Discussed|Trope}} in one episode. While appearing on a talk show Joe Friday explains to a TV audience that the reason cop killers get such a heavy response from the department isn't ''just'' because [[ItsPersonal it's their friend]]. To paraphrase, if someone's willing to kill a cop, would they hesitate to kill a civilian?
** In another episode Friday gives the same speech to a store owner when he comments that the police always put more effort into catching someone who has killed a cop than someone who has killed a civilian.
** In another episode two officers, a rookie and his training officer, are shot apprehending bank robbers, one of whom escapes. The older officer dies shortly after coming out of surgery and, according to the end of the episode, the captured robber was sentenced to death.
* ''Series/CriminalMinds'' has a number of unsubs who've killed cops. The most notable was one in the episode "Brothers in Arms" with an unsub that targets policemen. In another episode, there was a cop-killing unsub who turned out to be a cop himself.
* ''Series/TheMentalist'' had a SerialKiller who targeted police officers as the focus of the episode "Red Moon".
* In the last few minutes of ''Series/TheShield's'' [[FirstEpisodeSpoiler pilot episode]], Strike Team newcomer Terry Crowley gets shot in the head by none other than [[VillainProtagonist Vic]] [[CorruptCop Mackey]].
* ''Series/HomicideLifeOnTheStreet'' did this at least twice, with the same twist both times: the cop killer is himself killed shortly afterward, and the unlucky detective assigned to the case finds that nobody cares about justice for a dead cop killer.
** "End Game" has a racist SmugSnake (played by Creator/SteveBuscemi) get away with cop killing and practically brag about it -- only to be shot dead in the last few minutes. In the follow up, "Law and Disorder," the detective assigned to solve Buscemi's murder has to admit defeat because no cop will help him.
** In the "Justice" two-parter, a cop killer is acquitted in court and murdered shortly thereafter. The dead cop's son (played by Creator/BruceCampbell) is suspect number one, but nobody can figure out the evidence trail until one of the detectives casually mentions that Campbell owns a derringer. DaChief explains that when he was a junior policeman, the Baltimore police always executed cop killers without trial, and usually did it with a derringer (which was easy to dispose of, and couldn't be traced back to the department).
* In the pilot of ''Series/AlmostHuman'', [=InSyndicate=] attacks the precinct and assassinates LAPD Detective Vogel and another officer using a biological weapon.
* On ''Series/{{Copper}}'' a rookie police officer is stabbed to death and the other cops tear though the Five Points neighborhood looking for the killer. When they have no success, the local ward boss, an ex-copper himself, orders the closing of all the local pubs until the killer is found. In a neighborhood populated by Irish immigrants this is extremely SeriousBusiness. The killing was actually a gang initiation intended to make sure that the new member would never dare inform on the gang to the police.
* ''Series/{{CSINY}}'':
** One example is [[spoiler: Flack's LoveInterest, Angell]], who's shot in the season 5 finale while protecting a DonaldTrump[=/=]UsefulNotes/RupertMurdoch {{expy}}'s son (who was due to testify against him; [[spoiler: the killers turn out to be kidnappers, who knew this would put [[RedHerring immediate suspicion on their target's father]]]]). The episode also ends with [[spoiler: the bar they're holding a wake for her in being shot up in a drive-by]]. Nobody's killed (although Danny ends up in a wheelchair for a while), but it fits the trope in spirit.
** Aiden also counts, despite no longer being on the team. They were dead set on finding the perp and Danny was willing to beat up the guy he thought did it. Mac's speech in the beginning has a double meaning. He's talking about the dead Marine, being one himself, but it clearly shows with Aiden too. " You attack one, you attack us all.".
** Mac himself was a variant in the season 8 finale, having been shot InTheBack after stumbling into a drug store robbery while off-duty. He only ''nearly'' died, but the NYPD's reaction was largely the same as in a straight example.
* In ''Series/TheBlacklist'', the FBI gets into this part when they face off against heavily armed criminals and terrorists, resulting in their deaths.
* Happens throughout the ''Series/TwentyFour'' TV series when local police officers alongside CTU officers are killed by armed terrorists or criminals, serving as RedShirts.
* ''Series/TigerCubs''
** A new recruit on his first foot patrol gets killed in "King of Thieves" by Tin-yu's gang during a routine search.
** At the end of "The 2G Kidnapping Case", armed men kidnapping Fuerdais shot and killed Tsui Kin Hong while doing close protection duties with the [=SDU=].
** Senior Inspector Chin Hon-to has to calm his subordinates in the [=SDU=] when To Tin-yu and his girlfriend, Yiu Mei-ling, killed Yau Chun Hin in "King of Thieves Returns" for ruining the latter's face. Inspector Chin reminds his men that if they [[VigilanteMan acts as vigilantes]] and [[JumpingOffTheSlipperySlope go after them by themselves instead of using the law]], then they'll be [[HeWhoFightsMonsters nothing more than just a bunch of rogue cops acting outside the law]].
* ''Series/PersonOfInterest'':
** After the DirtyCop organization HR fails at attempting to frame Detective Szymanski as a DirtyCop in order to curry favor with TheMafiya, their leader, mayor's aide Alonzo Quinn, resorts to shooting both Szymanski and the DA trying the case. Quinn later sics HR on his own godson Detective [[spoiler:Beecher]] after the latter asks the wrong questions about the Szymanski murder.
** "The Crossing" and "The Devil's Share" form a two-parter with multiple examples.
*** At the end of "The Crossing" now-wanted HR member Simmons kills Detective [[spoiler:Carter]]. The next episode there's a city-wide manhunt for him. Unfortunately for Simmons, [[FanNickname Team Machine]] are also looking for him, and Reese in particular isn't inclined to be merciful. [[spoiler:After the rest of the team stops Reese, Fusco tracks down Simmons himself and arrests him, openly refusing to kill him in Carter's memory. TheDon Carl Elias is not so scrupulous and has him killed in the hospital because he liked Carter.]]
*** The page quote comes from a flashback in "The Devil's Share", where Fusco is unburdening himself to a police shrink that his first on-the-job kill wasn't a good shoot. He had [[VigilanteExecution hunted down and murdered]] a drug dealer who had killed an off-duty rookie and gotten off scot free.
* ''Series/BabylonFive'':
** "The Quality of Mercy" involves a serial killer who has murdered a number of people on the station, including a security officer, for which [[DaChief Garibaldi]] wants him ThrownOutTheAirlock.
** An odd variation in "Chrysalis" where we get the the typical police reaction without the actual death. Garibaldi is shot InTheBack by one of his own men after uncovering a plot to assassinate President Santiago. He doesn't actually die but he's comatose until "Revelations" in season 2. The security man who shot him (who is still above suspicion at the moment) then guns down his co-conspirators in cold blood and claims to the other guards that they took a shot at him. The other guards go along with this, despite the deceased's [[FrickinLaserBeams PPG]] clearly not having been fired, because it's a fellow cop (their beloved boss) who got shot.
** "Learning Curve" has Trace, a criminal overlord who brags about how he had heads of security on his last turf killed until he [[DirtyCop found one he could work with]] and he's trying to do the same on Babylon 5. A young Ranger gets involved, and since Trace sees them as some kind of law enforcement, he decides to use what he's got. The Ranger survives, barely, but Trace now has the Rangers' personal attention.
* ''Series/LawAndOrderCriminalIntent'': Occasionally dealt with; in particular, Alex's first husband was a police officer killed in the line of duty.
* In ''Series/{{Nikita}}'' the title character came to Division's attention after she was sentenced to death for killing a cop while high on ketamine. Division [[DeathFakedForYou faked her execution]] and brought her to their training facility. The full story is more complicated: [[spoiler:The cop was dirty and was threatening her foster mom. Nikita moved to protect her and accidentally shot the cop with his own gun.]]
* Happens a lot in ''Series/HawaiiFive0'' with HPD officers sometime being killed off while supporting Five-0, acting as in the capacity of RedShirts. Others include [=FBI=] and [=ATF=] officers, which drives the plot of a few other episodes.
* ''Series/{{Castle}}'':
** A variation in [[Recap/CastleS2E9LoveMeDead "Love Me Dead"]] where the victim is an A.D.A. rather than a cop. It's treated the same way by the cops at the scene, though.
** {{Subverted|Trope}} in [[Recap/CastleS3E7AlmostFamous "Almost Famous"]]. Castle and Beckett respond to an "officer down" call, but it turns out the victim is a male stripper in a police officer costume.
* ''Series/{{Justified}}'': Since protagonist Raylan Givens is a US Marshal, most villains end up as attempted {{cop killer}}s by default. In Season 3, Raylan's father [[ArchnemesisDad Arlo Givens]] becomes the genuine article when he shoots and kills Raylan's friend, State Trooper Tom Bergen, believing him to be Raylan. In Season 5, Boyd Crowder becomes one when he has Sheriff Nick Mooney assassinated--though given that Mooney was deeply corrupt, nobody cares--and Daryl Crowe Jr. narrowly avoids it when he shoots, but fails to kill, Raylan's boss, Art.
* In ''Series/TheTwilightZone2002'' episode "Another Life", a rapper keeps waking up to find himself in an interrogation room getting beaten up by enraged cops who accuse him of killing one of them. He protests that he has no idea what is going on, then wakes up and dismisses the events as nightmares. [[spoiler:It turns out the events in the interrogation room are really happening and his life as a rich and famous rapper are a dream. The cops eventually beat him into a coma, trapping him in the dream permanently (which he sees as a happy ending). The cops are then informed that the real cop killer was caught, and the protagonist was innocent.]]
* The ''Series/{{Elementary}}'' episode "End of Watch" starts with the murder of an NYPD Highway Patrol officer and the discovery that his sidearm has been replaced with an airsoft gun. [[spoiler:The officer had been trading police guns for oxycodone, replacing them with airsoft replicas, and after he tried to quit, the arms dealer killed him in order to use his funeral as a diversion while he robbed the ESU armory. After the traitor gets exposed and his funeral cancelled, he then murders another cop (who was completely honest and got picked at random,) to ensure there's another funeral]]. When the killer gets arrested and dragged out of his hideout, his SmugSnake attitude towards the couple of officers holding him gets a severe knocking as he's greeted by the sight of ''dozens'' of cops lining the street as he's put in the car, reminding him that he's made a lifelong enemy of every single person in the NYPD.
* In the first episode of ''Series/BrooklynSouth'' a guy goes on a shooting spree and kills a bunch of cops right outside the precinct house, then is himself shot and dragged into the house. He dies while waiting for paramedics to show up, and his relatives sue the police force alleging that the cops purposely let him bleed to death in revenge.
* ''Series/PoliceStory'': Third season "The Empty Weapon" has a juvenile criminal doing this while fleeing from a mugging that he did.
* ''Series/TJHooker'': Second season "The Empty Gun" has another sociopath juvenile doing this and another second season-er has the entire police academy the target of this by an vengeful former arrestee, who shot at a cruiser with two officers inside at the episode's opening.
* ''Series/{{Witchblade}}'':
** In the pilot {{Mafia}} hitman Tony Gallo murders Sara's partner Danny Woo in cold blood in front of her, and she spends the rest of the episode trying to catch him while learning to use the Witchblade. [[spoiler:Gallo also killed Sara's father, a beat cop.]]
** "Agape":
*** Narcotics detective Dean Gorner gets into it with Sara at a murder scene, claiming that Homicide is dragging its feet on investigating the death of Gorner's partner Torres and taking umbrage. [[spoiler:It turns out in the end that Gorner and Torres were {{Dirty Cop}}s and Gorner himself was the triggerman. He killed Torres for his share of the take.]]
*** Following on from the above spoiler, a drug kingpin refuses to kill [=McCarty=] or Gorner, because [[spoiler:"unlike you, I'm not a cop killer." But he's not above [[LeaveBehindAPistol leaving them both guns so they'll kill each other]]. Fortunately Sara and Danny get there in time.]]
* The ''Series/MadamSecretary'' episode "Standoff" revolves around the extradition to the United States of Carlos Ochoa, a Mexican drug runner who killed a Texas state trooper. The Mexican government insists on the US taking the death penalty off the table before they'll extradite him, angering the trooper's family and Texas Governor Caleb Lockwood.
* ''Series/BreakingBad'':
** The Cousins, Leonel and Marco Salamanca. They use their chrome axe to murder a tribal police officer who happens to stumble upon them. They later are directed on Gus Fring's orders to attempt to assassinate DEA Agent Hank Schrader, but fail (due to Hank being tipped off by Gus about their impending arrival one minute beforehand).
** Jack Welker and his Neo-Nazi gang, who are responsible for the deaths of [[spoiler:Hank and Steven Gomez]].
* A complicated case was seen in ''Series/BetterCallSaul''. Mike Ehrmantraut is a retired cop from Philadelphia whose son Matty also became a cop. Matty was completely idealistic, and when he found out that his partner and sergeant were dirty, was ready to turn them in to InternalAffairs. Mike frantically convinced Matty not to do this, because he knows cops will do ''anything'' to avoid prison, which could include killing Matty. Matty eventually backed down, but by that point the two {{Corrupt Cop}}s killed Matty anyway, convinced that [[TheStoolPigeon he was snitching on them]], and made it look as though Matty was killed by a criminal they were pursuing. Mike eventually lured the two into a trap and killed them both. Because of the complications at work there's also a schism in the response of other police: younger cops who don't know how notoriously corrupt those two cops were want to bust Mike and are willing to follow him all the way to New Mexico to do so, older cops who know everything that was going on want to just let sleeping dogs lie and figure the two cops got what they deserved.
* ''Series/TheWire'' repeatedly hammers home that criminals doing ''anything'' to incur the ire of the police is a very, very, bad idea, and everyone involved in organized crime is cognizant of this. Only the [[FearlessFool extremely foolhardy]] or most aggressive criminals try to do such a thing.
** Near the end of season 1, two soldiers of the Barksdale organization end up shooting an undercover officer during a hit on a police snitch. The officer survives, but the entire Baltimore police department cracks down hard on the criminals, whose leaders acknowledge the utter stupidity of their men's improvised actions. The one who actually pulled the trigger (acting impulsively without checking with his boss) gets [[YouHaveFailedMe disposed of quickly]], and every crook who hears about them shooting the cop reacts with WhatAnIdiot because of the massive, city wide crackdown it provokes.
** In season 3, the undercover officer Dozerman is trying to buy drugs when the dealers he's talking to simply rob and shoot him instead. Dozerman survives, but once again it triggers a massive police reaction with plenty of PoliceBrutality being used.
** The first part of painting the infamous Stanfield Organization as [[DarkerAndEdgier more dangerous]] than any previous criminal empire is the fact that they're perfectly willing to use violence against the police. In one episode, Carver and Herc go to tell Marlo Stanfield to show up at a parley that their commander, Major Colvin, is doing with various drug gangs. Stanfield refuses and Herc gets up in Marlo's face over this disrespect, but Carver notices that the various other members of the gang are all starting to reach for weapons, obviously with the intent of killing both Herc and Carver if they don't back off. Carver gets Herc to back off, but the fact that the Stanfield gang has absolutely no compunction about killing cops proves to be an early hint about just how ruthless and bloodthirsty the group will turn out to be.
* Augustus Hill of ''Series/{{Oz}}'' wound up in a wheelchair because he shot a cop while trying to escape arrest. After he was arrested and handcuffed, another cop threw the helpless Hill off a building as payback. Hill was lucky enough to survive, but unlucky enough to be paralyzed below the waist and get a life sentence.
* ''Series/JessicaJones'' gives us police officer Will Simpson (Nuke), whose sanity begins to slip after he's almost blown up by [[Creator/DavidTennant Kilgrave]], to the point that he guns down fellow detective Oscar Clemmons in cold blood.
** Kilgrave comes very close to being one in the scene where he takes an entire precinct hostage and commands the officers to all point weapons at each other or themselves.
* ''Series/Daredevil2015''
** Wilson Fisk has numerous NYPD cops on his payroll who are so corrupt they're willing to actively kill fellow officers who aren't on the take. And as Det. Christian Blake [[SickbedSlaying learns the hard way]], Fisk also has no qualms about having the corrupt cops on his payroll killed when they become liabilities.
** In the season 2 finale, archers who are members of the Hand gun down the first responding pair of cops by shooting them with arrows.
* ''Series/{{Monk}}'':
** "Mr. Monk and the Secret Santa" sees an SFPD homicide detective get poisoned at a Christmas party. It appears to have been a case of bad luck as the detective drank poisoned port that had been delivered to the station earlier that day and seemingly was meant to kill Captain Stottlemeyer. After the investigation clears the original suspect (a man whose brother Stottlemeyer had killed in a bank robbery, and who'd fired at Stottlemeyer in a parking lot a few months prior to the party), Monk finds that the detective murdered was the intended target, and he was killed by his jealous ex-girlfriend, a fellow police officer who couldn't stand that he wanted to get back together with his wife.
** "Mr. Monk and the Badge" sees the shooting death of a police officer named Russell [=DiMarco=]. As Monk finds out, he'd stumbled upon the identity of a notorious serial killer while on patrol. Knowing that he was ineligible for the reward money as a city employee, [=DiMarco=] had a friend from his high school softball team make a false tip that led to the killer's arrest, with the promise that they'd split the reward money. Only, said friend double-crossed [=DiMarco=], and thus shot him and kept the reward money for himself.
* ''Series/MajorCrimes'' has the Reverend Daniel Price, known as "Reverend Cop Killer" to the LAPD. As a [[GangBanger member of the Bloods]] he murdered an off-duty police officer during an armed robbery, but the case was dismissed with prejudice due to one of the investigating officers perjuring himself on the stand. In the present he claims to be a changed man and has become a pastor and community leader, [[spoiler:which turns out to be true in season four's five-part episode "Hindsight"]].

[[folder:Music]]
* In Music/BobMarley's song "I Shot the Sheriff" (also famously covered by Music/EricClapton), the singer [[ExactlyWhatItSaysOnTheTin confesses to being one of these]], although he claims [[CrimeOfSelfDefense it was in self-defense]] and that he was falsely accused of shooting the deputy.
* Music/IceT created a lot of controversy with his HeavyMetal song "Cop Killer," which he claimed was a ProtestSong against PoliceBrutality. After a firestorm of criticism he ultimately withdrew the song from circulation. (Ironically, the singer went on to play a cop himself on shows including ''Series/LawAndOrderSpecialVictimsUnit''.)

[[folder:Professional Wrestling]]
* Homicide's FinishingMove was called the "Cop Killa" for a while, before it was changed to the "Gringo Killa".
[[/folder]]

[[folder:Radio]]
* The ''Franchise/{{Dragnet}}'' radio series had an episode where Friday gives the same speech as in the '60s TV series above about why police go after cop killers so hard. It may have adapted the same case.

[[folder:Video Games]]
* ''VideoGame/LANoire''. Various side missions feature cop killers.
* ''VideoGame/CondemnedCriminalOrigins'' has the serial killerthe player is following shoot two cops at the start.
* ''Franchise/StreetFighter'': M. Bison is responsible for murdering Chun-Li's father, who was an Interpol officer.
* In the first ''VideoGame/MaxPayne'' game, the titular protagonist's real problems start not when he loses his family but when he is framed for murder of his fellow DEA agent. Gangsters in this game are cannon fodder that die in droves and no one really cares, but one dead officer is serious.
* In the first ''VideoGame/{{Mass Effect|1}}'', one of the missions on Noveria has you fight through the facility's security force to retrieve incriminating evidence on the corrupt boss of the place. On the way out, you run into the irate sergeant, herself going [[DirtyCop behind her captain's back]], who says, "You know what they do to cop killers on my world?" If Wrex is present, he retorts, "You know what they do to corrupt cops on mine?"
* Referenced in ''VideoGame/ShinMegamiTenseiIV'' when the [[KillerCop Zombie Cop]] demon decides to beg for mercy. Never mind that the "cops" you would be killing are already (un)dead.
* Referenced with the "Cop Killa" bonus (worth 5000 points) in ''VideoGame/GrandTheftAuto2'', which one can get by destroying twenty police cars.
* ''VideoGame/BatmanArkhamOrigins'' opens with the death of CorruptCop Gillian Loeb from ''ComicBook/BatmanYearOne''--[[spoiler:and despite being dressed as Black Mask, the deed is done by the Joker, much like in ''Film/TheDarkKnight''.]]
* ''VideoGame/PaydayTheHeist'': These are your main targets. The only other enemy types are gangs and mercenaries. Expect a regular Overkill run to end with the deaths of ''hundreds'' of FBI troopers.

[[folder:Webcomics]]
* In ''Webcomic/TheOrderOfTheStick'' Elan's EvilTwin, Nale, kidnaps him and kills the chief of police of Cliffport in the process; the rest of the CPPD reacts as you might expect. [[spoiler: Exactly as Nale planned. He disguises Elan as him and vice versa, leaving Elan in jail and him [[TheMole free to infiltrate the party]] (with the officers refusing to let the order check "Nale"'s claims via magic in case it [[OffOnATechnicality gets the case thrown out]]).]]
