i thought i was going to arrest the bad guys. i never thought i would become a bad guy myself. >> did you become a bad guy? >> oh, i did, yes. >> how bad? >> i became very aggressive, beating people, losing control, and using excessive force when there wasn't really any need for me to do that. i mean, i worked the most infamous police station ever known. it was called rampart. won best picture for denzel washington for his portrayal of this really bad police officer. >> i'm the police! i run [bleep] here! you just live here. >> was that an understatement? were there cops that bad? >> yes, there were. yes, there were. i was one of them. the problem was very systemic. we don't have so much that problem anymore.
