Two words with three syllables: Al Capone. Al Capone was a legendary Chicago gangster in the 1930s during Prohibition. Four of his collaborators murdered seven people with machine guns on February 14, 1929. It was called the St. Valentine's Day massacre. And that's not the only murder Al Capone was involved in.
