The Untouchables (1959)

S3E27 Arsenal

In January 1929, gangster Matt Malloy enters a sporting goods store, but finds he can't purchase an automatic pistol without a police permit. However, anyone with $150 can easily buy a machine gun. Later, at the Club Montmartre, several machine guns are displayed on Nitti's table. The Council declares it's time to take action against the Northside and Bugs Moran. Nitti grabs one of the guns and asserts, "You’ve got them—now use them!" A gang war is on the horizon!
