February 1, 1933. Late that night, John ""The Cropper"" Cropsie, the Enforcer for Jules Flack (boss of the Westside combine), stood in the back alley behind the Lido Burlesque house, by the stagedoor entrance-- and pumped some slugs into David Alpine, the key booze supplier for the combine (because he was also selling to the competition). On the night of February 2, Eliot Ness is having Cropsie reenact the crime in front of an eyewitness to the shooting.
