Michael J. “Umbrella Mike” Boyle, a Chicago gangster in the early 1900’s used to stand in a saloon at the appointed hour, his umbrella hanging by its handle from the edge of the bar. People who were eager to avoid labor trouble dropped bundles of currency into the umbrella as a means of protection.

Bertolt Brecht, a German poet, playwright, and theater director of the 20th century, once said, “It is easier to rob by setting up a bank than by holding up a bank clerk.”
