Jo-Jo was a master manipulator and corrupt cop in the movie Clockers.
He was portrayed by Michael Imperioli.
He is a sadist who enjoys torturing his suspects. In one scene when he busts a couple of yuppies from Connecticut going to Ahab's for having drugs, he says that if one of them doesn't give up the one who has the drugs, he's gonna see to it that one of them ends up raped in prison. He harasses Strike into giving some of his money up to him. He's an asshole much like Rocco.
