History Main / RabidCop

* ''Literature/{{Discworld}}'': THAT! IS! NOT! MY! COW!. Vimes does whatever he can to not 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.]]

* In ''Film/{{Dobermann}}'', Commissaire Sauveur Cristini is completely out of control. In one scene, he throws a bay across a room and [[PistolWhipping pistol whips]] the mother when she tries to go after her son.

** Elliot Stabler 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. 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.

** Ironically, when the series started, it was ''Olivia'' who was the borderline lawsuit waiting to happen, as she was the one who tended to browbeat people and assault suspects.
** 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.
** Frankly, most of the cast fits at least part of the trope description; as soon as they get a lead, they instantly assume that that lead committed whatever crime is being solved and attack them ''mercilessly.''

* The Mercykillers in ''VideoGame/PlanescapeTorment'' are already an entire faction of Judge Dredd-like {{Knight Templar}}s, but Vhailor is well-known for being extreme even by Mercykiller standards. Things like mercy ([[CaptainObvious duh]]) and compassion mean absolutely nothing to him in his pursuit of justice.

* [[RuleOfCautiousEditingJudgement Depending on how you view him]], Joe Arpaio. Similarly, David Clarke.

** David Tapp in the [[Film/SawI 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.

* Rancid Rabbit from ''WesternAnimation/CatDog'' in any episode where he is [[NewJobsAsThePlotDemands a police officer]].

* Bad Cop in "The Lego Movie". His EstablishingCharacterMoment includes Good Cop giving Emmett a glass of water (after getting battered by B.C.) only for Bad Cop to instantly swat it away barking out "too late!" and carrying out his interrogation, and he uses absurd amounts of overkill to try to stop him from getting to the Kragle.

* John "Sleepy" Estes, the titular ''Anime/MadBull34'', who currently graces the page with the picture on top. He doesn't do PoliceBrutality--he does Police ''[[ThereIsNoKillLikeOverkill Overkill]]'' (like carrying ''about a dozen hand grenades strapped like a loincloth under his pants'', just in case).

* ''Film/{{Identity}}'': Officer Samuel Rhodes. At first he's a reserved authority figure, but he becomes increasingly violent as people keep dying at the motel at the hands of a mysterious killer, eventually vowing to get through the night by gathering everyone in one room and threatening to shoot anyone who tries to leave. [[spoiler:Although, it's later revealed that he's not really a cop but a criminal posing as one.]]

** Perhaps [[ExaggeratedTrope the ultimate example]] is Judge Dredd's nemesis, Judge Death. He starts off his time in his reality's judge force [[HangingJudge executing perps for minor crimes]] (untied shoelaces, breach of noise regulations, loitering...). ''And he only gets worse''. Eventually, he reasons that all crime is committed by the living, [[AllCrimesAreEqual therefore life is a crime]]. Cue the extermination of his world's entire population and his attempts to do this to Dredd's universe.

** The second film, ''Film/MagnumForce'', has a whole group of these as a DeliberatelyBadExample. They start the film by going after criminals that have gotten OffOnATechnicality, but they perform their exterminations with an absolute disregard for collateral damage (even killing fellow cops that get in the way), and Harry asks to them on the denouement what will happen when they eventually become bold enough [[DisproportionateRetribution to start shooting anybody they can classify as "criminal", even jaywalkers and owners of really messy dogs]], with the answer given to him being "we will do as we please".

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

* ''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.

** Oddly enough, even when they have the actual capacity to be JudgeJuryAndExecutioner, this is averted by the Mega-City One Judges and ''especially'' Dredd--like any actual real police force, they frown greatly on members using excessive force without due justification and even so much as a single baton strike too many can put them in a whole heap of trouble with [[InternalAffairs the SJS]], if not worse. Of course, that's not to say Justice Department doesn't have any bad eggs. The likes of Judge Manners, who sodomises a juve with his daystick, or Judge Kruger, whose preference for using his daystick is so ingrained into him, he plants drugs on an innocent woman he beat to death, are rife within the department.

* 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. Also DependingOnTheWriter, ''Batman'' is seen as this to the rest of the superhero community, performing HighAltitudeInterrogation like nobody's business among other borderline-sociopathic steps to keep [[WretchedHive Gotham's]] crime in check.

%%* Bad Cop in "The Lego Movie". DUH. ...To those who've seen the movie, at least.
