prisoner's dilemma

two friends-gangsters get caught while commiting a crime, (prisoner's dilemma)one betrays the other to the cops to get off while the other is sentenced. they fight infront of the cops and but work together with distrust. they form a gang (same bussiness but possibly rival) The cops use the betrayer to get more info abt the other, wihle trying to get the other one to betray the betrayer. finally it can be revealed (or they realize the scheme and )the friends/gangsters turn it around to make the cops bad while legitimizing themselves.
