On this day in 1964, a jury in Dallas found Jack Ruby guilty of murdering JFK's assassin, Lee Harvey Oswald. You wouldn't think that would have been much of a trial, since Ruby was filmed by TV cameras shooting Oswald. But Ruby was represented pro bono by famed defense attorney Melvin Belli, who attempted (unsuccessfully) to argue that Ruby was legally insane at the time.
Was Jack Ruby just a pawn in a bigger, Mafia-led JFK assassination conspiracy? Well, his last words on his deathbed in 1967 reportedly were, "There is nothing to hide... There was no one else."
