Swift justice was meted out to Giuseppe Zangara, who tried to shoot President-elect Franklin D. Roosevelt in Florida on February 15, 1933, but mortally wounded Chicago Mayor Anton Cermak instead. Cermak died March 6. The murder trial began the next day. Zangara was convicted in a brief trial and was electrocuted March 20, just 33 days after the shooting.
