OMG I can't believe this one was not on the list! Harvey Kietel in "The Bad Lieutenant"
1. He shoots the radio in his squad for losing a bet.
2. He "polishes the bishop" on the side of a car with two girls in it that he pulls over cause their hot.
3. He stands naked in a room screaming after OD'ing on heroin
4. He kicks the crap out of two kids for raping a nun... Then buys em a bus ticket and lets em go!
5. He tries to swipe a kilo of cocaine underneath the nose of other cops to pay his gambling debts.
6. He has about 3 mistresses
Now tell me that is not bad...
