​Bootleg: To be distributed or sold illicitly.

Numerous ethnic gangs fought to control the local bootlegging activities. In Chicago, 800 gangsters were killed in gang warfare during Prohibition, primarily due to the fight over alcohol sales. Bootleggers counterfeited prescriptions and liquor licenses to gain access to alcohol. The most often used practice was to import liquor from other countries on ships. Some of the most famous bootleggers were Al Capone and George Remus who profited from over $5 million in bootlegging activities.
