Combating Crime in the Commonwealth in the 1920s and 1930’s

The Thompson Submachine Gun was designed by General John T. Thompson, who was inspired by the trench warfare of World War I to develop a "one-man, hand -held machine gun", firing a rifle caliber round. 1921 Thompson's were first sold in small quantities to the U.S. Post Office (to protect the mail from a spate of robber- ies), followed by several police departments in the United States.

The Thompson achieved most of its early notoriety in the hands of Prohibition and Depression-era gangsters and in Hollywood films, most notably in the St Valentine's Day Massacre.
