Fifty-nine years ago (22 November 1963), President John F. Kennedy was assassinated in Dallas, Texas. Ten months later (September 1964), the Warren Commission concluded that President Kennedy was shot by Lee Harvey Oswald and that the assassin had acted entirely alone.

Do you believe the official lone gunman theory, or was there a conspiracy? What if there were a truth market in which people could place bets on this question? (For what it’s worth, I propose just such a solution here and here, and I will address some possible problems with my proposed truth market during the Thanksgiving break.)
