Cosby (1996)

Season 1: Episode 3

To wrest control of his block from lowlifes (like the burglars who targeted him), Hilton forms a neighborhood-watch program (of sorts). Now watch the watch commander lose control and cause crime instead of preventing it: he intimidates a man who has just been mugged, has an innocent woman's car towed away, and then must explain why a missing elderly woman is found unconscious in the Lucas dining room.
