History DirtyCop / LiveActionTV

* ''Series/{{CSINY}}'' has done this repeatedly. Flack's mentor removed evidence that incriminated his son from a crime scene, Mac's first partner stole $200K from a perp back in the day and killed the guy's girlfriend to cover it up, Danny's old partner set up his current employer, a rich lawyer, to get robbed...

* ''Series/BetterCallSaul'': While ''Breaking Bad'' hinted at Mike Ehrmantraut's past as a dirty cop, in this series we get the full story. The Philadelphia police were so universally corrupt that Mike went along with it to prevent his partners from thinking he wouldn't have their backs, since he knew if they thought he would turn on them they would kill him first. His son Matt never suspected such a thing, and when he became a cop himself he initially balked at the idea of ever being on the take. Mike convinced him that he ''had'' to take the money, so Matt did, but his partners killed him anyway because he took too long to say 'yes'. Mike himself would go on to become the chief enforcer in Gus Fring's drug operation.

* ''Series/TheDeuce'' is about TheBigRottenApple of Times Square in 1971. As such, police corruption is rampant. Just about all beat cops are in the pocket of the mob and collect protection money from businesses. A new captain in the 14th precinct, however, arrives with the intention of cleaning house.

* Chief Wayne Unser from ''Series/SonsOfAnarchy'' is a sympathetic version of this. He helps out the local criminal motorcycle club and in return they provide protection for his trucking business. Unlike most examples of this trope, however, he does it because he believes the Sons are better for the town of Charming than the other gangs who would take their place if they were to disappear.

** Dwight Tilghman is a prison guard who routinely brutalizes Wee-Bey Brice because Wee-Bey killed a cousin of his. Avon Barksdale and Stringer Bell find out that Tilghman runs a side business of smuggling heroin into the prison. Stringer arranges for Tilghman's supplier to give him a tainted batch, and when several inmates are killed by the deadly drugs, an investigation is launched with the warden realizing that they'll need to promise reduced sentences to get potential cooperators willing to implicate the culprits. [[FramingTheGuiltyParty Avon comes forward and "accuses" Tilghman of the crime]]. Tilghman gets arrested when drugs are found in his car that corroborate Avon's "story", and Avon's first parole hearing is moved up as per the deal proposed by Maurice Levy with the prison officials.

** The episode "[[Recap/MidsomerMurdersS23E2 The Debt of Lies]]'' involves several people who would fall somewhere under this trope in their ''backstory'' (from fairly light misdemeanours to outright theft of a significant quantity of money), but have since retired (or in one case, starts the episode at their retirement party). It also features a subversion in someone who is dirty, and was a cop, but wasn't dirty ''as'' a cop.

** Sgt. Trevor Gibson in the episode "Sleeper Under the Hill". He is involved in the murders and does his best to throw Barnaby and Jones off the trail. He ultimately falls victim to his partner in crime.

** In Season 3 Ray covers up Renee killing Jorge and helps her sell drugs for money, because he cares about her now more than his job as a cop. He then helps Renee find a witness against her who can then get bribed to disappear.

** Also in Season 3, Jackie discovers that [[spoiler:Detective Tom Dolan]] has been helping a pimp, and murdered a drug dealer who'd stolen from him. Both she and Ray are disgusted because of his crimes, since it makes them all look bad.

* ''Series/{{Longmire}}: Malachi Strand is the former Chief of the Cheyenne Tribal Police who was little more than a gangster with a badge, demanding money from crime victims to do his job and then taking money from the criminals to let them off. Longmire finally arrested him for extortion before the series began, and describes him as one of the worst criminals he ever had to deal with. He gets paroled in the third season and becomes a long-running villain for the rest of the show.

* ''Series/{{Fargo}} [[Series/FargoSeasonFour Season 4]]'': The Kansas City Police Department of 1950 are very dirty, often brutalizing members of Loy Cannon's black gang. The resident cops of this season, Detective Odis Weff and USMarshal Richard "Deafy" Wickware, are not saints either. Weff is on the Fadda Family's payroll who stifles investigations into their activities, while Deafy is a bigoted Mormon who is very brutal towards criminals, if his story of his handling of Italian gangsters in Salt Lake City is true.

** ''Series/Daredevil2015'': Wilson Fisk cements a lot of his power through buying off cops and using them to do his dirty work for him.

*** Obviously, Ray Nadeem is the only agent on the detail who's not dirty, which is by Fisk's design. But even then, he's not entirely squeaky clean. His pride and desire to get a promotion to get a pay raise and get out of debt (thanks to a financial situation that Fisk orchestrated) lead him to blindly believe Fisk's "allegations" that Matt worked for him without bothering to think it suspicious that a member of the law firm that took Fisk down would secretly be working for him, and not take Karen seriously when she points out Fisk is using him as a pawn in a vendetta. His pride also keeps him from realizing Fisk is playing them all, and by the time he finds out about Dex's treachery, it's too late to back out. He ends up becoming a reluctant accomplice after Hattley blackmails him, though this only lasts for a short time. Being forced to be Dex's driver when Fisk sends Dex to Matt's church to kill Karen to avenge her murder of James Wesley, a hit during which Father Lantom gets killed taking a baton meant for Karen, ends up being the breaking point that leads to Nadeem finally growing a spine and making an effort to break with Fisk (with Matt and Foggy's help). It doesn't work, and he gets killed by Dex on Vanessa's orders, though not here before making a video confession naming all of the various crimes Fisk ordered FBI agents to commit for him.
** ''Series/LukeCage2016'':
*** Misty Knight's partner Rafael Scarfe is in the pockets of the Stokes gang, and sabotages investigations that are a threat to Cottonmouth. In season 1, he murders the last survivor of a three-man crew that robbed a gun deal of Cottonmouth's, Wilfredo "Chico" Diaz, when Chico tries to turn state's evidence on Cottonmouth, and then uses Chico's information to sell Luke out to Cottonmouth. Later, when informed that Internal Affairs has him under investigation, Lt. Perez tasks Scarfe with getting Cottonmouth's guns out of evidence, with the help of a property sergeant who's been bribed to falsify papers saying the guns have been destroyed. But being under investigation, Scarfe decides to blackmail Cottonmouth, demanding $100,000 in funds that he knows Cottonmouth doesn't have. This prompts Cottonmouth to attack him, get hold of his gun, and shoot him with it. Scarfe manages to last a full day before dying, but not before spilling the truth to Luke and Claire about everything he knows. Sadly, his death means that none of his information is usable in putting Cottonmouth away, which combined with the police department brass not being happy with another police corruption scandal on their hands just a year after the one with Wilson Fisk, means Cottonmouth walks.

** ''Series/ThePunisher2017'':

** ''Series/JessicaJones2015'': Season 3 has Carl Nussbaumer, who murders teenaged drug dealers whose deaths won't be minded by the criminal justice system because they'll be chalked up to gang violence, and steals their money and product to resell. He gets blackmailed by Eric Gelden and, later, accidentally killed by Trish Walker.

* ''Series/TheTwilightZone1985'': In "Crazy as a Soup Sandwich", Cassandra Fishbein threatens to call the cops if the mob boss Nino Lancaster and his henchmen Gus and Bork don't leave her hairdressing salon. Nino advises against it as most of them work for him.

* Sgt. Trevor Gibson in the ''Series/MidsomerMurders'' episode "Sleeper Under the Hill". He is involved in the murders and does his best to throw Barnaby and Jones off the trail. He ultimately falls victim to his partner in crime.
