Akai and Kanie from Kite use their status as homicide detectives to lead the investigation of a series of professional murders away from the true criminals. They are also the employers of the true criminals.
And that's not all they're mixed up in either. Akai in particular when it's revealed that he's been raping and brainwashing Sawa, one of the child assassins he and Kanie employ.
It's quite plausible that the Triad leader Mr. Chang in Black Lagoon was one of these as a cop. Chang is a darker take on several John Woo characters, but his past as a cop seems to allude to Tequila from Hard Boiled. Since Tequila fought gangsters and Chang is one, it stands to reason that he wasn't that honest of a cop.
Chief Watsup, the Chief of Police in Roanapur. Not only on the take from the various cartels that run the city but has also used his authority to get an unfair advantage when collecting bounties put out by the cartels.
Ginza of Speed Grapher is mostly a Rabid Cop, given her habit of "self-defensing" people (she actually uses it as a verb), but she's kind of a dirty cop as well. She's shown essentially committing insider trading based on the crimes going on, and because of her jealousy of Kagura, she abuses her authority to obstruct Saiga, the hero. By the end of the series, she has a Heel Realization and ends up a better person.
Mad Bull 34 is a bizarre example - as part of the Buddy Cop Show dynamic, Officer "Sleepy" John Estes takes the Cowboy Cop's tendency see justice done through venues outside the law to the extreme. He's running prostitution in his neighborhood, because the way he sees it that stuff will always be there and at least if he's in charge he can keep it from getting out of hand and it keeps the girls safe. That said, it's all part of a larger Batman Gambit. He's also really good at killing criminals. You won't want to watch him work, but you can't imagine what the city would be like without him.
The title characters of Noir kill a few of these over the course of the series.
In the Naruto pilot, the Inspector and his subordinate turn out to be one, killing Takashi, stealing the painting and framing Naruto for both.
The Uchiha Clan in Naruto become this. They are the village's military police, yet they conspire to overthrow the rightful government in a Coup d'état since they see being cops is 'below their station'.
It's a lot more complicated that, and honestly, asides from the aforementioned coup, there is no evidence in the manga to suggest this trope.
Monster has two of these: the two detectives who are hired by Johan to kill Nina's adopted parents and the ones from Prague, Commissioner Hamrlik, Chief Detective Batella and, Detective Janacek.
In one episode of Nerima Daikon Brothers, Gagdet Detective Yukika tries to catch the eponymous group by cooking up a rumor that the chief of police is in league with the yakuza, and the money from their dirty deals is in a vault under the station, knowing they'll fall right into her trap. However, when the NDB tunnel in, they find that the chief of police actually is in league with the yakuza, much to Yukika's surprise.
In the Crapsack World of Gangsta crooked cops like Chad and Cody are honestly some of the most goodhearted people around. Yeah, they hire mercenaries to slaughter local trouble makers for the placation of powerful Mafia families, but at least they're doing so to keep the peace and prevent widespread slaughter.
Less noble policemen are noted to except bribes and clean-up unwanted corpses.
Almost every damn cop in Sin City, with the notable exception of John Hartigan.
Likewise in Gotham City, with the exception of Gordon and one or two good cops. This becomes a major plot point in Gotham Central, a series set within the Major Crimes Unit of the Gotham City Police Department, the only consistently honest branch of the department. Since its members are all personally selected by the commissioner they have a modicum of integrity and competence, but the universal corruption of the rest of their force makes even their simplest of cases difficult since the other departments are stealing evidence, accepting bribes, and often committing the crimes themselves. This comes to a head in the Corrigan story arcs, where Jim Corrigan (The dirty cop of the series) is selling crime scene evidence on the black market, redistributing the heroin that is collected by the narcotics department, and eventually starts personally murdering other police officers that are trying to stop him. At the end of the series, though everybody knows he did it, his web of corruption has spread so far that the case against him is sabotaged and he gets off completely free until Final Crisis Aftermath where it comes back to bite him in the ass.
And the one time Internal Affairs and the MCU are actually able to build a case against him they have to compromise their morals and let him go to save one of their own.
Even the MCU isn't immune. Harvey Bullock may have been more of a Cowboy Cop most of the time, but everyone agrees he went too far when he gave one of his Mafia connections information on a man in witness protection so they would kill him. The man in question shot Commissioner Gordon, but still.
In his pre-Crisis origin, Bullock WAS a dirty cop, on orders from the mayor to sabotage Gordon's career, but then came to respect him.
Bludhaven is even worse than Gotham. Criminals there who don't share the profits from their crimes with the police are murdered. The police chief has placed a bounty on Nightwing's head.
In the Astro City "Dark Ages" story arc, Charles' partner Lannie takes weekly bribes from the criminals to overlook their activities. Charles refuses to get involved, rejecting the bribes but refusing to report Lannie to Internal Affairs. He gets shot in the back as a result.
The Brotherhood in X-Men Noir, Chief Magnus' private task force dedicated to controlling the criminal element from within. Magnus is dedicated to the pursuit of justice, but as he says, "laws only work on the law abiding."
Luke Cage Noir, meanwhile, has Officer Rachman and Tombstone, corrupt cops working for Randall Banticoff. Tombstone in particular was a gangster before (and after) he became a cop.
In The Tainted Grimoire, there are Khamja operatives within the ranks of the Jylland Defenders of the Peace.
Harry took a rather cynical view of law enforcement in general in Harry Potter and the Mind:
"There are two general kinds of person who become policemen, or aurors. One group is made up of starry-eyed young people who see opportunities, and want to change the world into a better place. Another group is made up of those who want an easy government job, and like to be able to bully and boss people around, ignore red lights, and steal an apple whenever they like.
"After the young idealists are on the force for a few years, they find out that they cannot change the world after all. So they become embittered and hardened to suffering, or leave the force. So who does that leave waking the beat? The bully. The bully is not your friend."
Most of the cops from Batman Begins (with the exception of Gordon) and then Ramirez and Wuertz from The Dark Knight. It's implied that Ramirez had some moral issues with what she did to Rachel Dawes and the Commissioner's family but we never find out about Wuertz.
In some of the promotional animated materials that bridge the timeline of the two films, Ramirez is shown to have a VERY sick mother that the mob is using to force her to be a dirty cop (offering much needed money for her bills and threatening her life if Ramirez doesn't cooperate).
Gordon notes to Dent, in The Dark Knight, that if he chose not to work with cops Dent investigated in Internal Affairs, he'd be working alone.
Any cop in Batman (except Commissioner Gordon), especially Lt. Eckhardt who is hired by Grissom to kill Jack Napier.
Every policeman in Hobo With a Shotgun: "At least he's only killing the dirty cops." "We're ALL dirty cops!!"
American Gangster: A gang of corrupt detectives make life difficult for both drug lord Frank Lucas (Denzel Washington) by demanding money, invading his mom's house and destroying her furniture, shooting his dog and assaulting his wife, and honest cop Richie Roberts (Russell Crowe) by almost taking $10,000 in bait money and outright telling him not to arrest Frank to keep the drug/bribe business going. They're only stopped when Frank and Richie team up to catch all the corrupt cops that Frank knows, nearly 3/4 of the police force.
In addition to the detectives, Richie's career is ruined when he and his partner don't keep a million dollars, making the other corrupt cops in his squad suspicious that they'll turn them in. This drives his partner to stealing and drug use, culminating in a fatal overdose on Frank's "product."
Assault on Precinct 13 (the remake, anyway): A group of dirty cops with very superior firepower attack a lonely police station in order to silence the gangster who could expose them.
The Negotiator: Lt. Danny Roman is accused of murdering a cop (his former partner and best friend) and suspects he's been framed by his fellow officers in a conspiracy. Commander Frost eventually confesses about a scheme to steal money from the police retirement fund, which Roman inadvertently got dragged into when his friend got killed for starting to catch on.
Melbourne Detective: I'll tell you how this game works Daniel. We're the cops, we get to ask the questions. You're the suspect, you get to complain about your civil liberties, perhaps get shot, maybe even killed. And it has to stay like that Daniel, otherwise everything falls out of balance. When things fall out of balance, you know what happens then don't you Daniel. Your spiritual values start to decline. You get your disintegration of your social structure, don't you? The system collapses. Petulance, flood, famine. It happened to the Romans, it happened to the Greeks, it happened to the Ancient Mesopotamians. And we don't want it happening to us do we Daniel?
The customs official in The Dogs Of War putting aside half the protagonist's belongings as "Airport Tax" and "Importation Tax".
Super Troopers: practically the entire Spurbury police department. Finding this out results in the state trooper protagonists getting to take over their jobs after their branch is shut down due to budget cuts.
They're not so much dirty (I can't actually recall them taking any bribes), as they are 'playful'. For instance, Ramathorn takes the swinger couple to his home for sexy time, but when the evening's up they have to go back to jail. The couple doesn't seem too broken up over it.
Keaton in The Usual Suspects is the leader of the group of criminal protagonist, and as described by the Hero Antagonist cops was one of these. He had ties to organized crime and murdered several people. Also, the villain protagonists conduct a heist that involves robbing corrupt NYPD cops and the cartels which are paying them.
Kujan tries to portray himself as a good cop in contrast to Keaton, but he's all too willing to say that, if Verbal doesn't tell him the whole story, he'll call in every favor he has in the underworld to have Verbal killed.
Serpico is full of dirty cops. The title character is notable for not being one of them. Even worse, the film is based on a true story.
Commander Forrester in Scanners 2. He wants to take power by building an army of scanners (telepaths) to keep everyone else in line, and using those he already has to wring himself into higher positions of authority, by killing the police chief, manipulating the mayor into appointing him as his replacement, and killing her as well when she finds out too much, among other things. His lackey Gelson is one as well.
The Corrupt Hick police officer in The Final lets the jocks go in exchange for them handing over all of their weed... which he is later seen smoking. In a deleted scene, we see that he does the exact same thing with good-looking women, in exchange for sex.
Played with in Fallen, where early on Denzel Washington's character explains to a new transfer that while he doesn't take bribes, he doesn't really care all that much if other cops do, since he figures they are still putting their lives on the line and out there doing good 90% of the time anyways.
A ring of dirty cops want to kill a witness in 16 Blocks.
Major Calloway from The Third Mancomes across as one for the first act or two.
Barricade from the live action Transformers movie is a Decepticon that can turn into a police car.
Changeling has Captain J.J. Jones, who is willing to go any length to protect the image of the LAPD, including giving Christine a stand-in for her missing child, forcing her to care for him, and committing her to a mental institution when she finally decides to stand up for herself.
Payback features two dirty cops. They both get what's coming.
Also notable because these two cops are, besides the Internal Affairs officers in one scene, the only cops in the whole movie.
He wasn't actually corrupt. The robber baron was in fact the rightful finder; the laws of 1930s America probably didn't cover the protection of archeological findings from such people.
Dirty Cops are a fact of life in The Elite Squad. Nascimento muses that the police have enough manpower to clean up the city, but it's a lot easier and safer to take bribes and look the other way... unless you're a member of BOPE.
The main character of the film Murder Most Likely, which incidentally was a film-ization of a real life story.
In Arnold Schwarzenegger's End Of Days, it appears the entire NYPD are secretly Satanists. And not the fun, pot-smoking free-love Satanists either, but the "murder witnesses and abduct women" kind.
Detective Kaota in Outrage works for Yakuza and is the one coming out on top of the affair.
Hot Fuzz has the never-seen Uncle Derrick, who was arrested for selling drugs to students. Ironically, he inspired his nephew Nick Angel to become a genuinely good cop. One of the film's main villains, Frank Butterman, is also this. Though in his case, he's more of a Well-Intentioned Extremist.
Some of the earlier scenes in Once Upon a Time in America featured an officer who keeps troubling the main characters (a group of children who are forced to steal to survive). It eventually turns out he takes bribes to ignore the actions of specific criminals while still prosecuting others. However, this is much less prominent in the later parts of the film when the children have grown up into vicious gangsters.
There's also Danny Aiello's Chief Aiello, who's paid by a steel company to break a strike.
Officers Warren and Norton in Bride of Chucky. They collaborate to plant a bag of marijuana on Jesse just because he's dating Warren's niece, Jade.
In The Jerky Boys: The Movie, the two title characters find out that the entire Queens organized crime division is in league with a local crime boss, making it difficult to turn over evidence on said crime boss to the authorities.
Anthony Quinn's character in Across 110th Street, who hides this by masquerading as a Cowboy Cop.
The Mexico City police in Man on Fire is full of them. The kidnappers outright hire off-duty cops to assist in Pita's kidnapping.
This trope is the main focus of Dark Blue, and provides several examples.
Eldon Perry frames people for crimes, shoots suspects, and behaves like an all-around Jerkass. Later on he becomes repentant of his actions and atones with a speech that uncovers all of his and Van Meter's shady dealings.
Perry's supervisor Jack Van Meter is one through and through, and oversees and orders all of Perry’s corrupt actions. He's even revealed to be the person Orchard and Sidwell answer to.
Bobby Keough subverts it when he has serious moral qualms with the illegalities committed in the department.
Towards the end of Wild Things, Ray Duquette is revealed as one of these. He was corrupt, beat hookers, murdered anyone he didn't like, and got Suzie sent to prison just for the hell of it.
Major plot point of Cellular as it's revealed several Homicide Detectives are in on a corruption ring.
It's probably fair to say that the majority of James Ellroy's characters are either dirty cops (or feds) or former dirty cops. Dudley Smith is just the one most people know. Edmund Exley was also far more compromised in the book than the film. Although the books (where Dudley Smith is around until the end of White Jazz does subvert this a bit by having Exley make the bringing down of Dudley Smith his first priority as Chief of Detectives (although this is more because of personal dislike than anything professional).
By the end of White Jazz, Exley is compromised, essentially having become the counter-Smith within the department. The entirety of the action is the protagonist being caught in the power struggle between the criminal empire Smith has built and Exley's own quasi-criminal means to achieving his ambitions. Eventually, Exley drops his hatred for Smith in favor of his political ambition and the protagonist ends the book, decades later, deciding to return to LA to bring both men's sins to the light. The protagonist, Klein, is himself quite the Dirty Cop, but the ultimate point is that his sins pale in comparison to either of theirs.
Blore, one of the villain protagonists of And Then There Were None is a former cop, whose crime is fitting up an innocent man, leading to his victim being sentenced to hard labor and dying in prison. Blore is presented as devious and amoral, suggesting this was indicative of his general behavior as a police officer.
The In Death series: This trope has popped up a number of times in the series, with Judgment in Death and Treachery in Death standing out in particular.
Subverted with Officer Shrift from The Phantom Tollbooth. Sure, he arrests people for no reason and throws them in jail, but he does it as a joke. Unless they really do something bad, they can leave any time they want.
Walker, Texas Ranger: Several episodes had corrupt cops, mainly in background roles, but one — the Season 4 episode "The Brotherhood" — was the focus of an episode. A small-town police department is run by a police chief frustrated about the crime rate and the perception that criminals get off on technicalities, so they kill the suspects after they are freed by the court. At one point, the crooked officers turn things up another notch when they throw a lighted cocktail into a prison bus, killing several prisoners and the guards and badly burning the driver. The main focus of the episode was on a Marine Corps recruit named Ernesto Lopez, who had been accused of rape only for DNA evidence to exonerate him; Walker is unable to get to Ernesto before the overzealous cops do, and Walker is left to track down the two stooges. The chief eventually turns his gun on himself when he learns Walker is coming for him.
Adam-12: Several episodes dealt with corrupt fellow officers of Reed and Malloy, the most notable of the lot being the 1971 episode "Internal Affairs – Blackmail," where one of Malloy's best friends is being investigated for blackmailing a witness.
The Dukes of Hazzard: Sheriff Rosco P. Coltrane, who invariably looks the other way as Boss Hogg engages in corrupt scheme after corrupt scheme, and then attempts to pin the blame on Bo and Luke Duke.
BJ And The Bear and Sheriff Lobo: The title character of the latter series, who in the former show tried to put truck driver B.J. McCay out of business by pinning various crimes on him. In his own series, Lobo always tried to manipulate various schemes to his advantage.
The Bill has had several, most famously Don Beech.
A Noodle Incident in "Mr. Monk Gets Fired": we learn that the new commissioner has a personal vendetta against Monk ever since a cop friend of his was put in jail
The Detective Mole type in "Mr. Monk and the Captain's Marriage": the killer is a police officer securing the scene, who is implied to be working for a known racketeer
In "Mr. Monk Is On The Run," Parts 1 and 2, the one-time Sheriff John Rollins is this. He works for Dale "The Whale" Biederbeck.
The Expanded Universe novel Mr. Monk and the Dirty Cop likes this trope, as there are three: First is Paul Braddock, a former SFPD detective Monk, Natalie and Stottlemeyer encounter at a convention. Monk and Natalie later learn from Stottlemeyer that Braddock had a long history of physically beating up people, to the point that Stottlemeyer threatened to turn him over to Internal Affairs. Unsurprisingly, when Braddock turns up dead, Stottlemeyer gets blamed for it and is wrongly arrested, since they had an altercation hours before the murder at a wake (making Stottlemeyer the second "dirty" cop). The third is Nick Slade, Braddock's real killer, who turns out to have taken out a hit on an entrepreneur years beforehand.
At least two on JAG; Royal Ulster Constabulary Inspector Vincent Hutchinson in "Trinity" who arranged the kidnapping of the infant child of an American naval officer and an IRA member, only to put the blame entirely on the IRA; and DC Detective Frank Coster in "The Stalker", who did not only stalk Mac, but killed her former boyfriend Dalton Lowne and kidnapped her.
They've also been seen on NCIS, although usually as a one-off.
In a flashback we find out that Tony left the Baltimore police department when he found out that his partner was dirty.
NCIS Los Angeles had a group of dirty cops who acted as an escort service for drug dealers and other criminals. Turns out they drew the line at helping terrorists
DCI Roy Slater ("Slater the Slag") in Only Fools And Horses episodes "May The Force Be With You", the 1985 Christmas special "To Hull and Back", and "The Class of '62".
The second episode of Rock and Chips, "Five Gold Rings", shows us that after leaving school, Slater immediately joined the police force.
Firefly has the downright brutal Lieutenant Womack, who is a member of Allied Enforcement but who likes to smuggle human organs on the side.
The Strike Team on The Shield can be seen as the poster boys for this trope, with the added twist of half the team (Curtis Lemansky and Ronnie Gardock) being good cops who fell in with the wrong crowd and largely stayed in the shallow part of the corruption pool, and Vic Mackey and Shane Vendrell, who killed fellow police officers in order to cover their own asses when they were in danger of being exposed.
They also sell drugs they get from buy-busts, use torture to interrogate suspects and protect drug dealers they can control, all in the name of "keeping the peace".
Being a bad guy on Damages seems to entitle you to at least one (and usually more than one) corrupt cop/FBI agent on your payroll who is willing to surveil, harass, or murder anyone who bugs you too much.
They usually don't actually show up, but the existence of these is sometimes part of the reason why the clients on Burn Notice can't just call the cops. In "Unpaid Debts" they ran afoul of a group of them, and in "Question and Answer" Sam pretended to be one.
Life On Mars has a number of episodes which revolve around Gene Hunt and his superiors' relationships with local gangsters or corruption in general. Ashes to Ashes Series 2 was a complete arc about the fight between Hunt and various corrupt Met officers such as Mac, which doesn't end with Mac's death part way through the series.
Criminal Minds has a cop who has a hero homicide complex, he sets ups a shooting so he can make himself a hero by being the first to respond. He attacked Garcia fearing that she could find out about his murders.
Weeds has a number of dirty cops and Nancy even ends up married to a dirty DEA agent.
Justified has Doyle Bennett who is a subversion. He IS a corrupt cop, but only in matters concerning his family.
Season 1 featured a corrupt sheriff who worked for a Miami drug cartel. He struck a deal with them so he could get revenge on a child killer. He is actually a fairly effective sheriff since he is able to crack down on illegal drug manufacture and sales in the county. The drug cartel is not interested in selling drugs in the county and helped him get rid of the local meth manufacturers who were their competition in other areas. Things go bad for him when the cartel asks him to help them kill Raylan.
Season 3 had an election for sheriff where both candidates were in the pockets of criminals. The incumbent hardly hesitates before accepting a Briefcase Full of Money from Quarles. When Boyd Crowder realizes that the sheriff works for Quarles he recruits his own candidate to run for the position. Subverted in the end because Boyd's candidate pays back Boyd by warning him about an arrest warrant and then states that their deal is done and he is not doing more favours for Boyd.
Against the Wall plays with this trope a lot. It is based around a protagonist in the Internal Affairs division always investigating cops or other law enforcement officials. Sometimes played straight, sometimes subverted.
Homicide: Life on the Street had the Arson Unit, of which Kellerman was the only cop NOT on the take. Kellerman spends almost the entirety of Season 5 bitching about how he's not dirty and then at the end of the season he goes and shoots Luther Mahoney, unjustifiably. And then he coerces his partners into covering it up.
There was also at least two other storylines involving Police Brutality and murder of suspects by police.
Law & Order occasionally brought up cops on the take. It even implied that one of its main detectives might be dirty. Fontana wore very nice clothes and flashed a big roll far too often for a simple detective.
Back when he was "on the sauce", Briscoe was implied to be dirty (or at least surrounded by a lot of other dirty cops). By the time he joins the 27th Precinct, he only pretends to be a dirty cop in order to get his informants to trust him.
CSI NY has done this repeatedly. Flack's mentor, Mac's first partner, Danny's old partner...
Brass was originally an aversion of this, stating how he refused to be a dirty cop. But now, he is flirting with subverting it, ever since he covered up Ray Langston's unjustified killing of Nate Haskell by pocketing Ray's flex cuff at the scene.
Detective John Sheppard in the penultimate episode of Stargate Atlantis barely manages to keep his job by scraping by on his quarterly performance reviews, has illegal gambling debts and quits the force to skip town after stealing money from a crime scene. Rodney McKay is extremely disappointed in him, since met another version of him that was honest and determined and a member of the Earth's defense against alien threats. He turns around before it is too late, and dies stopping the villain.
Leverage has surprisingly few for a show about Robin Hood like thieves. Virtually all of the targets are Corrupt Corperate Executives with a dirty cop not appearing at all until well into the second season. Hardison also impersonates a dirty cop during "The Boys Night Out Job" convincing Mexican drug dealers that he can help them.
Dyson and Hale from Lost Girl are a twist on this concept, as they are not so much corrupt as they have different loyalties than they should as police officers: they're big on the whole "protect and serve" thing, but their main job is to cover up Fae (psrticularly Light Fae) involvement in human crimes. There's a second level to this as well, as Dyson is actually more loyal to Trick (the former Blood King, but in practice nothing more than the owner of a Fae way point) than he is to the Ash, the leader of the Light Fae, and both he and Hale are more than willing to turning a blind eye to Bo breaking Fae law ( as much as Fae law actually applies to Bo in the first place). Hale is also willing to ignore Kenzi's occasional brushes with human law(as well as spring her when she's incorrectly suspected of a crime), although he does stop short of actually helping her to receive stolen property.
Fusco in Person of Interest starts as a dirty cop working for the first Person of Interest. Reese gets just enough blackmail to force Fusco to work for him as a Friend on the Force, where he provides information and surveillance. Despite his growing desire to be a good cop, Reese has him play a dirty cop to infiltrate HR, a powerful group of NYPD corrupt cops.
One POI was on the run from her abusing husband, a corrupt US Marshall who used his authority to track her down when she left him.
1-800-Missing takes this trope to its logical extreme in one episode: the entire department being investigated is corrupt.
Sheriff Graham from Once Upon a Time has a good heart, and ultimately is a good cop most of the time, but he's completely under Regina's thumb and will plant or tamper with evidence for her.
Copper is set in 1864 New York and is full of Dirty Cops, including the hero and his friends. The police force of the time were notoriously corrupt and for the most part acted as just another street gang. When the detectives foil a bank robbery, there is a definite pecking order as to who gets to steal what from the crime scene. The informant gets to grab a few coins, the detectives get to stuff their pockets with some bank notes, the sergeant gets a pocket watch belonging to one of the dead robbers and the captain gets to deliver the remaining money back to the bank and decide how much he will keep as payment for the 'protection' his cops provided.
Hustle would sometimes feature Dirrty Cops who thought they could manipulate the crew for their own ends. This always ended badly for them. D.I. Fisk in "Curiosity Caught the Kat" is a typical example.
In the Season Six finale of Psych, it turns out that all of Henry's old friends from the force were paid for guarding a drug lab back in the day.
The White Bulls of Witchblade are a whole organization of these.
Chief Wayne Unser from Sons Of Anarchy 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.
The Rizzoli And Isles episode "What Doesn't Kill You" revolves around for the hunt for dirty cops in the Boston Police Department. Suspicion falls heavily on Jane for a time. The chief dirty cop turns out to be the head of Internal Affairs.
Grimm Captain Renard who secretly has connections with the Wesen world, and is secertly Wesen himself.
The second verse of Lupe Fiasco's "Handcuffs" is sung by a drug dealer, commenting on his arresting officer, making such remarks as "You ain't no better than me, just a hustla with a badge."
Phil Ochs' song "Here's to to State of Mississippi" decipts the cops in Mississipi that way:
They're chewing their tobacco as they lock the prison door Their bellies bounce inside them as they knock you to the floor No they don't like taking prisoners in their private little war Behind their broken badges there are murderers and more
The NWA song Fuck Tha Police has quite a few of these
Chamillionaire's hit song "Ridin' Dirty" was about racial profiling with particular regards to cops pulling over black drivers and hassling them (known as Driving While Black). This is a common theme in hip-hop and rap songs.
When you start off as a nobody in Pizza Tycoon, the police are pretty much straight edge. Once you have learned some street smarts and have some respect in the community, you'll be able to pay your way out of trouble and into the police's favors.
Edi E. from Final Fight took bribes from the Mad Gear Gang, controlled a part of the city, and got the crap beaten out of him by the heroes. He later double crosses the Mad Gear Gang by arresting it's members during the events of Final Fight Revenge.
The Undercover Cops in the beginning of The Lost And Damned, however they're killed in "Bad Cop Drop", a very early mission.
A group of NOOSE and FIB Agents in The Ballad Of Gay Tony, who intend to frame Ray Bulgarin by planting fake evidence in his truck. They're killed off in the mission "Going Deep".
B.B. from Max Payne turns out to be one of these, especially when it's learned that he killed Alex at the Roscoe Street Station and had Max framed for it.
Winterson in the sequel, who has a love affair with the Big Bad.
The entire UFE in part 3, being essentially the private army of the Big Bad and working with outlawed paramilitaries to abduct and organ-harvest the poor. Ironically, despite Rodrigo dismissing him as another of these, Da Silva is the only one we see onscreen who isn't.
Sumaru City's police force seems to have a bit of a problem with these, to put it mildly. One of them is a boss battle in Eternal Punishment.
The Godfather: The Game doesn't just have beat cops, but also FBI agents on the take who will help you keep the other families under control if the vendetta escalates to open Mob War.
Resident Evil 2 has Police Chief Brian Irons, a wife-beater and multiple rapist who is on Umbrella's payroll and thus not only works to conceal their wrong-doings, but is also implied to discredit potential competitors and provide human test-subjects for them. He's also a lunatic who suffers a mental breakdown during the resultant Zombie Apocalypse, actively sabotages the efforts of his police to aid the human survivors, and finally takes to hunting them down and killing them himself.
On top of all of that, the game also drops heavy hints that he may be a Serial Killer as well. And by hints we mean the human skulls in his secret taxidermy chamber.
Made worse in Outbreak. One of the files in the first scenario notes that 8 blonde women, all ages 18-23, started disappearing and people were saying there were groans and screams in the sewers. The description matches his last victim in RE2, the Mayor's daughter.
There's also a case of this in the first Resident Evil, albeit a rather unusual example: Albert Wesker was the team captain of Division A of the S.T.A.R.S. Precinct and presumably also their leader, and seems outwardly to be a model cop. However, he is in fact a double agent for the Umbrella Corporation, and more importantly is intending to lure the S.T.A.R.S. Teams to their deaths at the hands of B.O.W's both to silence them and to give the B.O.W's battle data, and later games reveal that he was in fact also planning to betray Umbrella as well.
An interesting aversion in Ace Attorney is Detective Tyrell Badd. He's a good man, a good cop, and the third 'leg' of the virtuous thief Yatagarasu.
Another interesting aversion is Dick Gumshoe... Although that might be because he's Too Dumb to Fool.
Now, dirty lawyers we have in spades. Manfred von Karma, Kristoph Gavin, Jacques Portsman, Calisto Yew...
And then there's Damon Gant who is a dirty police chief, and was strongly implied to be forging evidence before he killed anyone. There's something seriously broken about the Ace Attorney legal system.
Apollo Justice introduces us to Daryan Crescend, who is an international affairs agent who smuggles cocoons into the country (for good reasons) and kills Interpol agents (not for good reasons). We've also got Valerie Hawthorne from T&T, who helped fake a kidnapping and frame an innocent man, though she did try to make up for it.
Agent Ross from Red Dead Redemption, who's hobbies include kidnapping people's families in order to force them to track down outlaws he should be tracking.
C-Sec officer Harkin from the Mass Effect series, although he is fired from the force by the second game. Anderson mentions that the only reason he lasted as long as he did because humanity wanted a presence in C-Sec and it would look bad if he were busted for one of his numerous crimes. By the sequel, there are enough humans working in C-Sec that it was no longer a concern, so he was sacked.
Captain Bailey is a deconstruction of this trope with a sympathetic POV. He's willing to take bribes from The Mafia... but only because it helps keep the peace and keeps his men alive. He authorizes rough interrogation of prisoners... but only because the crime rate in his district is awful and he feels the need to use extra force. He's also on Shepard's side for the most part and will bend the rules for him/her when he needs to.
Officer Kaira Sterling from the Noveria corporate police is openly taking bribes to cover up Administrator Anoleis' corruption, and is more than willing to murder anyone who gets in the way.
Kaira: Do you know what we did to cop killers back on my world? Wrex: Do you know what we did to dirty cops back on mine?
L.A. Noire has the entire LAPD except for Cole Phelps and his partners. Except for his fourth partner, Roy Earle, on the Ad Vice desk.
Dead Rising has Jo Slade working as a mall security raping women and beating them with her nightstick.
Dead Rising 2 has one also: Raymond Sullivan is working for Phenotrans all along.
Tashmann from the first Drakensang game: the first time you see him he's trying to use his badge to hire a prostitute for free.
In Devil Survivor, after a few days in Tokyo after a lockdown resulting from demon presence, a group of police officers begin abusing the power of demon-summoning objects called COMPs to rob and/or kill others. They eventually surrender their powers after being beaten twice, the second time when faced with the lord of death, Yama.
All 3 of the player characters in Call of Juarez: The Cartel are dirty to some degree.
LAPD Detective Ben McCall is on the lighter end of the scale; he steals petty cash from criminals to help pay for the medical expenses of the child of one of the many hookers in his jurisdiction that he's protecting, he otherwise has a very strong sense of justice (although he also has anger issues and is prone to Cowboy Cop behavior as well as the Jack Bauer Interrogation Technique). By "street cop" standards he's practically a boy scout.
DEA Agent Eddie Guerra is on the much more extreme end of the scale; he's secretly running a network of street dealers to sell drugs for him, in order to pay off his huge gambling debts. He also sets up an informant to be murdered because he was worried Internal Affairs was getting to the guy. It also turns out he was The Mole and helped the Cartel abduct key witness Jessica Stone, because they owned his gambling debts.
FBI Agent Kim Evans is by all appearances an idealisitic Good Cop, but is (reluctantly) willing to commit crimes, obstruct the investigation, and outright murder witnesses when ordered to do so by the director of the FBI, supposedly for The Greater Good (although it turns out most of her crimes were the result of her being mislead by the director).
George Sewell in Silent Hill Downpour. Especially in the end reveals he killed Frank Coleridge and pin the blame on Murphy.
Commissioner Kinsler is shown in Halo3: ODST's data pads to be concerned with nothing but his own personal interest, even as the Covenant are invading New Mombasa. If you manage to collect 29 data pads, you'll find out that the cop whom you've been fighting alongside with is on Kinsler's payroll.
In Mortal Kombat, it would really be wrong to say that Stryker is any worse than the other characters who are supposed to be good guys (all of them are willing to use lethal force). Still, his Battle Cry in the 2011 game is "Police brutality comin' up!" (Also, in that game, Stryker is unique in that he is the only character who appears to kill his opponent upon winning a match even if he does not successfully perform a Fatality; he throws a grenade offscreen, which results in an explosion, followed by a scream from the loser and a lot of blood.)
In the "Phoenix Rising" Story Arc from Sluggy Freelance, Officer Tod is actually a former mob enforcer. He's found a pretty sweet gig where, as long as he covers up the local Vigilante Woman's numerous murders, he can just sit back, do nothing, and collect a fat paycheck from the government.
In The Gamers Alliance, George Bush is a dirty officer in the Maar Sul's SAVAGE who accepts bribes and looks the other way when the Totenkopfs act and does his best to help the cult's evil cause whenever he can.
Gronkh's mini-Let's Play of the game "Die Polizei" (a police simulator) was about being a racist, sadist, foul-mouthed asshole, to emphasize the bad quality of the game and spice it up.
The royal guard is corrupt and abusive, although its officers try to keep things safe and reasonable.
Roger from American Dad turns into a dirty cop when he joins the police force in one episode... about three hours after joining, no less.
Took him that long?
Family Guy: Parapeligic officer Joe Swanson has outright looked the other way many times when his closest friends – Peter, Quagmire and Cleveland – break the law, even if not explicitly stated as such in the given episode. Instances include:
Numerous episodes: Quagmire's repeated preying on (and having sex with) teenaged girls; to a lesser extent, Peter.
Numerous episodes: Peter repeatedly abusing Lois – particularly in "The Courtship of Stewie's Father" – and Meg (countless episodes).
"Jerome is the New Black": Peter causing a fire at his new friend Jerome's house, this out of jealousy and hate when Peter believes that Jerome (a black man) is having an affair with Lois.
"Family Goy": From his upstairs window, Peter shoots a gun at his Jewish neighbor Mort Goldman while he is at his mailbox (a scene emulating an infamous scene in Schindler's List). Not only does Joe fail to arrest Peter, HE ALSO SHOOTS HIS GUN AT MORT (greeting him with a friendly hello to boot)!
"Burning Down the Bayit": Peter and Quagmire conspiring with Mort Goldman to burn down Goldman's pharmacy (to allow him to collect an insurance settlement).
The King of the Hill episode, "Lupe's Revenge", has a police woman who severely abuses her power. Naturally, in accordance with Hank's hilariously bad luck, she falls in love with him.
In Minoriteam the villainous Dirty Cop is a police officer made of dirt and grime who actively participates in the White Shadow's evil schemes and, like many of his cohorts, is virulently racist.
Chief Wiggum and the Springfield police in The Simpsons are sometimes shown to be corrupt as well as incompetent.
Wiggum's badge has "Cash Bribes Only" written on it.
Which is odd, as "I Love Lisa" implies that he got the Krusty 20th anniversary special tickets as a result of a bribe when he (unintentionally) caught Krusty in a porno theater.
Lisa: That story isn't suitable for children. Wiggum: Really? I keep my pants on in this version.
An inverted example involving Wiggum, he has also been willing to break the law for a very honorable reason: To help Homer's fugitive mother escape arrest, as her crime caused his asthma to be cured when he was younger. He has done so twice.
From the theme song from ''Cops In Springfield'': "Springfield cops are on the take/What do you expect for the money we make?/Whether in a car or on a horse/We don't mind using excessive force."
In the French cartoon Patrol 03, the series' Big Bad was the chief of police herself.
Think of Coslada, a peaceful little town 12Km southwest of Madrid, Spain, where everything seemed normal until it was known that the local chief police was a total Corrupt Hick, who almost had overthrown the town via recruiting new and young officers who just joined the academy so they could beat people and were completely loyal to him, demoting older and experienced honest agents to lower grades or sending them to other jurisdictions, imposing "taxes" on restaurants and shops in the town, harassing local commerce owners who didn't accept paying these "taxes", sexually harassing female agents and managing to make life hell for them if they refused or took action against him, employing city hall cars to hang around at the best pubs in Madrid, Invading the jurisdiction of the Cuerpo Nacional de Policía (National Police Corps) which have competence over locals on serious crimes such as murders, and moving a whole prostitution network into the capital. Prior to that, he was just known for his love on Press Conferences about any event taking place in the town, even stealing spotlight from the Mayor.
The London Metropolitan Police were at one time absolutely infamous for this sort of thing; not just taking backhanders but selling of siezed narcotics, pocketing cash recovered from armed robberies and falsifying evidence. Successive crackdowns from the 1970s onwards seem to have eliminated the worst of it.
