On November 2, Brown was sentenced to death by hanging with the sentence carried out on December 2nd. They didn't waste any time back then, did they?

Took em a whole month.

Here is a case in which they really meant business.

Giuseppe Zangara (September 7, 1900 – March 20, 1933) was an Italian immigrant and naturalized United States citizen who attempted to assassinate then-President-elect of the United States, Franklin D. Roosevelt, on February 15, 1933, 17 days before Roosevelt's inauguration.During a night speech by Roosevelt in Miami, Florida, Zangara fired five shots with a handgun he had purchased a couple of days before. He missed his target and instead injured five bystanders and killed Anton Cermak, the Mayor of Chicago.

Cermak died of peritonitis 19 days later, on March 6, 1933, two days after Roosevelt's inauguration. Zangara was promptly indicted for first-degree murder in Cermak's death.

"After spending only 10 days on death row, Zangara was executed on March 20, 1933, in Old Sparky, the electric chair at Florida State Prison in Raiford. "

March 6 - March 20 is less than a month.
