You've got to be kidding on JFK!!!! This is the one that stands as THE one that has been "proven" - see if you can find the film entitled "The Men Who Killed Kennedy" - it's an amazing British Documentary on all the FACTS and EYWITNESS accounts including "badgeman" - the "police officer" that was carrying a gun in the grassy knoll. There were far too many strange and unexplained circumstances and far too much "missing" evidence not to mention dozens of honest hard working average citizens who will swear to God they heard shots coming from the grassy knoll - then there is the obvious - JACK RUBY - Here's a guy that despised the Kennnedy's and had documented ties to the Mob. Dig in and research what he had to say in the months and weeks before his death. It's honestly one of the classic "conspiracies" of all time and it would be a shame if you didn't at least do some research into this. I beg you to at least try.
