Gary oldman killed it in leon: the professional. He was so evil. Harvey keitel in cop land, that evil french cop in kiss of the dragon, ricky tan in rush hour 2 and of course denzel in training day.

Vick Mackerley and the Strike team were consistently naughty, hana

The shield?
Spoiler alert for them spoil sports out there! Y'all like spoiled milk, stop crying over it!

1. All the cops in Serpico except for Frank Serpico..
2. Harvey Keitel in Bad Lieutenant
3. Brolin as Trupo
4. Forest Whitaker & Crew (Jay Mohr etc) in Street Kings
5. Matt Damon in The Departed

• I wouldn't say Denzel in Training Day because you actually wanted him to win in the end. How can a guy be that dirty or bad?

"Boyo" !

I can't believe no one has mentioned James Cromwell in LA Confidential yet.

Colin Farrell in Pride And Glory.
Paper snow. A GHOST!!

Maniac Cop of course

In Cop Land Harvey Keitel, Arthur J. Nascarella, John Spencer, and Robert Patrick play some very dirty cops. They killed fellow officers, planted evidence, and stole from various people. Sylvester Stallone's character ,who was already half deaf, was made permanently deaf by them.

Someone mentioned Gary Oldman earlier.I thought his portrayal of the cop in Leon was pretty dirty too!

Dirtiest cop ever was Harvey Keitel in Bad Lieutenant. The next closest was probably Matt Damon in The Departed and then Captain McCloskey in The Godfather.

I was amazed that no one mentioned this earlier.

Almost the entire police force in Serpico.
Its that man again!!

Dirtier.Keitel in Bad lieutenant.We dont know too much about Alonzo in Training Day but he seemed to more go to extreme,very cunning measures to save his life and those measures included murder,something we dont see Trupo commit.Those two might be dirtier but Trupo is my favourite,I think.
Brolin gives the movies best performance(seems to be the general opinion) and if you take away Trupo,most of the films tension is gone.He creates a trifecta or triangle of enemies,three men that have reason to despice,shake down or take down the other two.
I think he is my favourite crooked cop cause he got balls the size of your head. Not only extorting Lucas but when he gets a warning and his car gets blown up,he doesnt get scared,he gets pissed offhe threatens to throw Lucas in the river and steals his dope.
On top of that,bitchslapping Lucas bitch,raiding his house and killing Franks dog.he represents everything thats wrong and especially WAS wrong with law enforcement back then but still.Scotts attempt to manipulation of the audience borderlines to pathetic.We are actually suppose to see Trupo as the REAL bad guy since he represents the law?No,didnt fly.Trupo gets my respect precisally bacause of WHO he was extorting.poor little drug kingpin who gets 15 years in jail for ruining thousands of lives. Screw Lucas.

Nicholas Cage did a very good job recently in The Bad Lieutenant: Port of Call - New Orleans, as dirty as they come, worth checking it out.

You are right Gary Oldman in The Professional has to be considered.

Gary Oldman in The Professional, yeah- but Trupo just really pissed me off- I think Josh Brolin was extremely effective in this role.

I wouldn't say Disney princes but pretty close. And I never really looked in his eyes. 'Denzel' in Training Day played a much better role. Point out how Stansfield is frightening and is diffrent between 'Denzel' in Training Day and Trupo in American Gangster.
