S5·E3 Shivaree on Delancy Street

A black gang infiltrating a white ethnic gang's numbers racket makes four very big mistakes, in ascending order of importance: robbing and killing a pickup man for his bets and the numbers; shooting Broadhurst (knocking him out of the episode after the first scene) when he tries to interfere; framing the unconscious Broadhurst for skimming money from the numbers runners; and depriving a VERY well-connected Jewish tailor of his winnings.
