->'''FBI Agent Norman Jayden''': Blake, you are an unbalanced, psychopathic asshole!\\
'''Lieutenant Carter Blake''': I'll take that as a compliment.
-->-- ''VideoGame/HeavyRain''

The room is small. Help is far away, on the other side of many locked doors. Your arm is chained to the table and a Rabid Cop is [[JackBauerInterrogationTechnique spraying spittle into your face]] in a way that convinces you that he has completely ''lost his mind.''

All he wants you to do is admit that everything [[UsefulNotes/AdolfHitler Hitler]] did was your idea. Sounds good to you. What do you have to sign to get ''away'' from this maniac?

The Rabid Cop might be [[DirtyCop casually dirty]], or [[KnightTemplar overbearingly self-righteous]], or anywhere in between, but they all have two things in common: a reckless disregard for civil rights, and an unwavering conviction that any person they've identified as "the perp" really is a perp (regardless of any contradicting evidence) and deserves to suffer. In a GoodCopBadCop routine, they usually take the "Bad Cop" ball and run clear out of the stadium with it. Likely to enjoy using TortureForFunAndInformation.

Compare/contrast the (presumed) sympathetic CowboyCop.

!!Examples:

[[folder:Comics]]
* Gotham City Police Detective Harvey Bullock from ''Franchise/{{Batman}}'' dips into this quite a bit - which makes it [[{{Hypocrite}} very strange that he also often scolds Batman for being a vigilante]]. Of course, this varies DependingOnTheAuthor; also, it could be that Bullock just resents Batman for making the police look incompetent.
[[/folder]]

[[folder:Film]]
* Terence [=McDonagh=]'s partner, Stevie Pruit, is one of these in ''Film/TheBadLieutenantPortOfCallNewOrleans''. And [=McDonagh=] starts to turn into one himself as his addictions spiral out of control.
* Shannon Mullins in ''Film/TheHeat'' is a rare female example.
* Dennis Peck from ''Internal Affairs'' ...see Alonzo.
* Officer Mooney in ''Film/KillerKlownsFromOuterSpace'' has to be almost physically restrained from beating up a couple of punks brought in for public drunkenness. He later takes a flashlight to the head of one of the klowns, which turns out to be [[MuggingTheMonster not such a hot idea]]. (Of course, Mooney ''is'' an elderly man, so [[BoisterousWeakling he comes across as more of a jerk than a genuine bully]].)
* Bud White of ''Film/LAConfidential'', hands down...to the point he frightens the officer trying to play 'bad cop', as well as the suspect.
* Detective Park Doo-man and Detective Cho Yong-koo from ''Film/MemoriesOfMurder'' both brutally try to beat and torture confessions out of their suspects, one of whom was a mentally handicapped young man, and get very few results. They're contrasted with Detective Seo Tae-Yoon, who uses logic and reason in his investigation, [[spoiler: but by the end of the movie, is driven to becoming almost as bad as them.]]
* Henry Oak in ''Film/{{Narc}}''. In a similar vein to the aforementioned Alonzo Harris below, he happens to be a narcotic police officer with a case of PoliceBrutality against the criminals he's facing against.
** Nick Tellis himself is not far off from being a violent cop too. The reason why he was kicked out of the police force was because of him shooting a drug dealer holding a child hostage, resulting in one of his bullets hitting a pregnant woman.
* ''Film/{{Saw}}'': David Tapp in the first movie. His recklessness nearly kills one of Jigsaw's victims, gets his partner shot by multiple shotguns at once, gets his ''own'' throat cut, nearly killing him, and gets him dismissed from the force. And that is just [[FlashBack backstory]]. By the time the events in the movie proper start, he is a broken shell of a man in a fetid bedsit across from the house of the guy he thinks is the killer. It is arguably creepier than any of Jigsaw's actual traps.
** Detective Eric Matthews in the second movie. As the movie progresses, it's revealed that he has a very nasty record of violence towards suspects, and in several cases planted evidence to gain a conviction. And after spending most of the film watching his son trapped in a house with the victims of said evidence-planting, he resorts to thrashing the living daylights out of Jigsaw for the location of the house, [[spoiler:which turns out to be a trap set up specifically for Matthews.]]
* Although he isn't in the circumstance described above, Alonzo Harris from the film ''Film/TrainingDay'' is the embodiment of this trope. He is not necessarily insane though, just genuinely evil and sociopathic.
* ''Film/{{Transformers}}'':
--> '''Barricade:''' ARE YOU USERNAME '[=LADIESMAN217=]'?!?!
* Agent David Kujan pulls this on Verbal Kint a couple of times in ''Film/TheUsualSuspects''.
--> '''Verbal Kint:''' The DA gave me immunity.\\
'''Dave Kujan:''' Not from me. You get no immunity from me, you piece of shit!
%%* Bad Cop in "The Lego Movie". DUH. ...To those who've seen the movie, at least.
* ''Franchise/StarWars'': It's the overriding characteristic of the Jedi Knights (especially Mace Windu) in the prequel trilogy. (The costumer even mentioned dressing the Jedi in black so they would look like intergalactic police officers.) They become increasingly vigilante-like and subversive in their attitude toward the Republican Senate, until they finally decide that they must execute (okay, forget "execute", ''lynch'') Chancellor Palpatine in ''Film/RevengeOfTheSith'' because he is a Sith Lord and because he could just manipulate the courts into setting him free if he were ever arrested. During the attack on Palpatine, Windu seems to have totally lost his mind - and, in that light, Palpatine and Anakin Skywalker's murder of him looks less like the Dark Side and [[WoundedGazelleGambit more like self-defense]].
** Well, for one thing, there's no way to deprive Palpatine of his Force powers other than rendering him unconscious, so there's a good chance he'd escape if they tried to detain him.

[[folder:Live Action TV]]
* Ray has moments like this in ''Series/BreakoutKings'', including threatening to burn a suspect's genitals with a cigarette lighter.
* The aptly named Detective Slaughter from ''Series/{{Castle}}'', a one episode character played by Creator/AdamBaldwin.
** Kate Beckett herself was this at various points, usually when the case involved her mother's death. After [[spoiler: she is shot by a sniper]] she becomes this way when investigating that case as well as anything that reminds her of it.
* Jimmy Beck in ''{{Cracker}}'', once causing his superior officer to say 'I don't know what you did to him, but you scared the hell out of me.'
* Before Andy Sipowicz, there was Mick Belker on ''HillStreetBlues''. Dude even barked and growled like a rabid dog. Bit people on a regular basis. "You gonna tell me what I want to know or am I gonna have to show you my ass!"
* Elliot Stabler from ''Series/LawAndOrderSpecialVictimsUnit'' can be a violent person during his interrogations, especially when ItsPersonal. Which is roughly every other week. This tendency earned him the FanNickname Un-Stabler. Most likely because Elliot is increasingly unstable and psychotic. Many theorized the series would not end until he actually killed someone, ending his massive fall from grace... and ironically, while he did end up off the show due to a killing in the precinct it was A) a 'clean' (wholly justified) shoot of someone that was shooting up the holding cell and B) happened to be a 14 year old girl he was wholly sympathetic with.
** The cop in the (ironically named) episode, "Unstable", made Elliot look normal.
** Dana Lewis is also an example of this. Though she did have a running gag where, in every episode she was featured Elliot would end up being hurt in some way, the episode "Penetration" ends with her chasing down her rapist and cornering him in a warehouse with her gun drawn. This after being nothing but [[UngratefulBastard rude]] to Elliot and Olivia, and she actually tries to shoot the guy. The episode "Secrets Exhumed" ends up with her being arrested and thrown in prison for 25 years for killing her ex-boyfriend's girlfriend out of jealousy and spite.
* ''Most'' of the 1973 detectives in ''Series/{{Life On Mars|2006}}'' are rabid by today's standards, especially in contrast to 2006 transplant Sam, but Gene Hunt deserves a special mention, here.
* The retired detectives of ''Series/NewTricks'' have slightly CowboyCop attitudes compared to modern police methods and standards. So they see nothing wrong with creating a fake Rabid Cop scenario where the interrogator gets so insanely angry that he shoots the suspect's public defender lawyer. The 'lawyer' is another retired cop and the gun is a starter pistol.
** And occasionally they find themselves working alongside a real Rabid Cop, such as Frank Patterson in "The Fourth Man".
* Andy Sipowicz from ''Series/NYPDBlue''.
* ''Series/TheShield'' is about the Strike Team committing a lot of police misconduct in the name of stopping gangs and enriching themselves. Vic Mackey in particular counts as such. While he is a proponent of the JackBauerInterrogationTechnique, Vic only rarely turns into the rabid cop - usually, his menacing is done with a cold and calculating air.
** ''Series/SonsOfAnarchy'', also created by KurtSutter, has Lee Toric, a former U.S. Marshal, and ATF Agent June Stahl
* Jack Regan of ''Series/TheSweeney'' got rabid at times, too.
* Peter Boyd of ''WakingTheDead'' tends to get EXTREMELY SHOUTY and verges on violent at times, though usually one of his team is watching through one-way glass and bursts in to stop him.
* Colin Mochrie played a parody of one on ''Series/WhoseLineIsItAnyway'' in a game called [[http://www.youtube.com/watch?v=BhLKLcQ5XF4 Good Cop, Bad Cop]].
* Jack Malone of ''Series/WithoutATrace'' can be pretty worked up and he will do anything to get information on on those poor missing people.
* Several police on ''Series/TheWire'', but standout examples are Anthony Colicchio, who attacks a middle-school teacher for asking him to move his police car, and Eddie Walker, who breaks a teenaged carjacker's fingers just for giving him additional paperwork.
* ''Series/{{Copper}}'': If you trigger Corcoran's BerserkButton, he will not hesitate to unleash a NoHoldsBarredBeatdown on a chained prisoner.
[[/folder]]

[[folder:Literature]]
* Creator/StephenKing's ''Literature/{{Desperation}}'': Collie Entragian. ''I'm going to kill you'' Not all he seems, ''I'm going to kill you'' this being a Creator/StephenKing novel. ''I'm going to kill you.''
* ''Literature/{{Discworld}}'': THAT! IS! NOT! MY! COW!. Vimes does whatever he can not to turn into one, to the point that he [[spoiler: actually has a Vimes-esque entity in his mind to prevent him from succumbing to the darkness.]]
--->"Who watches the watchman? I do."
* Averted in ''Literature/TheDresdenFiles'' book ''Changes''. Rudolph tries his best to play the Bad Cop, but all his desk-pounding and spittle-flecked screaming manages to do is cause Harry to crack up and the other interrogator ends up ordering him out of the room. It probably helps that Harry has seen Rudolph ''freak out'' whenever confronted with the sort of thing he deals with all the time.
* Captain Zuccho from ''Literature/{{Incompetence}}'' has a HairTriggerTemper, to put it lightly. Asking him to calm down will result in him randomly ''shooting at the pavement''. Reputedly, he is on Prozac, but it doesn't seem to be helping.
[[/folder]]

[[folder:Video Games]]
* Agent Robert Nightingale in ''VideoGame/AlanWake'' is a ruthless federal agent pursuing the main character. Though the source for his violent behavior is found in [[AllThereInTheManual his back story]].
* Lt. Carter Blake in ''VideoGame/HeavyRain'' is a psychopathic police officer with immunity from the local precinct (why, nobody knows) who prefers beating a suspect rather than extracting any information, has no problem with breaking the law in order to investigate, and will have no qualms about killing. Initially, he's rather reserved to just beating suspects, and then he roughs up a psychologist who has done absolutely nothing. And then does everything in his power to assure those affiliated with the investigation that [[PapaWolf Ethan Mars]] is the Origami Killer. [[TheProfiler The FBI agent attached to the investigation, Norman Jayden]], isn't convinced, and the two have a very rough rivalry. If Ethan is arrested, then it leads to a [[MoralEventHorizon scene where Blake will mercilessly beat Ethan into unconsciousness]]. Jayden can intervene and punch Blake, which will prompt him to hold Jayden at gunpoint, waiting for the perfect opportunity to kill him.
** It doesn't stop there. One possibility at the end of the game has Blake [[spoiler:ordering his squad of officers to gun down Ethan who had finally reunited with Shaun, his ten-year-old son, after having gone to incredible lengths to save him from drowning in the warehouse's well, all while the aforementioned son watches in horror as his beloved father's body falls to the ground, lifeless. All because Blake refused to believe anyone but Ethan could be the Origami Killer and the instant the obviously unarmed man clutches his left hip in agony instead of keeping his hands up, Blake gives the order to shoot]]. Needless to say, Blake is by far the most hated character in the game, even the actual killer doesn't come close. The worst part? In any good ending [[KarmaHoudini he gets away with everything]].
* Saren Arterius of ''VideoGame/MassEffect1''. As a Spectre, he's essentially a Council space cop with no strings attached, and he plays it to the hilt - making frequent usage of the JackBauerInterrogationTechnique, pursuing his own ambitions on the side and pinning the collateral damage on people he doesn't like. He's the same sadistic, racist government law officer we've seen in many other works - just relocated to a sci-fi setting. And this was what he was like ''before'' he went JumpingOffTheSlipperySlope.
* A good way to lose in ''VideoGame/PoliceQuest'', acting like the aforementioned Carter Blake above will not be tolerated in the force.
[[/folder]]

[[folder: Western Animation]]
* The titular character from the Creator/AdultSwim show ''WesternAnimation/AssyMcGee'' is an extremely violent parody of this trope (and a HeroicComedicSociopath) despite being, as his name suggests, a pair of ass cheeks. He was perpetually intoxicated, told to hand in his badge and gun at least once an episode, and other offenses too numerous to list here.
* Though not technically a cop, Lock-Up from ''WesternAnimation/BatmanTheAnimatedSeries'' definitely counts.
* This is parodied in ''WesternAnimation/TheBoondocks'' where a Rabid Cop violently accuses and assaults ButtMonkey Tom Debuoir for a crime that he obviously didn't commit before being forced out by the nice cop. He then rushed in 5 seconds later to assault Tom again.
* ''WesternAnimation/IronManArmoredAdventures'' gives us their take on the NYCPD and the inexplicability of FamilyFriendlyFirearms at the same time. Doppelganger!Tony has just shot at unarmed people at a party with a laser gun and rushed off. The real Tony Stark is taken in for questioning, and one of the officers is like this, complete with banging on the table and yelling, "Did your friends give you the lasers?!"
* The Springfield Police Department is sometimes depicted this way on ''WesternAnimation/TheSimpsons''. (To the tune of "Bad Boys" from ''Series/{{COPS}}'': "Whether in a car or on a horse, we don't mind using excessive force!")
* Rancid Rabbit from ''WesternAnimation/CatDog''. Saving the fact that he also serves as TheRival to Cat.
* The Angry Cop from ''WesternAnimation/TheGoodeFamily'' episode "Gerold's Way of The Highway".
* Adult Swim did this twice with the ''WesternAnimation/HarveyBirdman'' episode "Bootie Noir" and the ''WesternAnimation/StrokerAndHoop'' episode "I Saw Stroker Killing SantaClaus".

* This can be TruthInTelevision on occasion. It's hard to not to find a list of incidents where PoliceBrutality is involved.
