Apparently, John Wilkes Booth's Daddy Was Not an Andrew Johnson Fan

Editors of the Andrew Johnson Papers at the University of Tennessee have authenticated a letter from Julius Brutus Booth, father of actor, assassin, and drunkard John Wilkes Booth, in which Booth the Elder tells the president to pardon two men convicted of piracy or "I will cut your throat whilst you are sleeping." For some reason, I hear Hank Jr.'s "Family Tradition" playing in my head.
