 The scene where Al Capone (Robert De Niro (qv) suddenly pulls out  a baseball bat at a dinner party and beats to death two of his men  is based on an incident that happened on May 7, 1929. Two of  Capones most feared killers, Albert Anselmi (qv) and  John Scalise (II) (qv), had hatched a plot to kill Capone and take  over his gang. Capone got wind of it and invited all his associates  to a dinner party, including Anselmi and Scalise. In the middle of  the party, Capone pulled out a baseball bat and battered both men to  death, then shot them both in the head.
