January 1929. Gangster Matt Malloy walks into a sporting goods store; he can't buy an automatic pistol without a police permit, however anyone with $150 can buy a machine-gun. Later, at the Club Montmartre, half a dozen choppers are laid out on Nitti's table. The Council says that now they can move in on the Northside and Bugs Moran. Nitti picks up a chopper and says, ""You got 'em-- use 'em!"" Gang war!
