"John Wikes Booth was a crackpot and he did kill Lincoln."

He was an established and famous actor from a famous family of actors. In some ways a crackpot, perhaps, but not at all a total zero of a loser like Oswald.

Like I said, he was a Hollywood type (before there was a Hollywood). Yup, he sounds like a crackpot. ;-)
