By whom? He was assassinated but I think the Cuban Mafia did it. But never was convinced that Oswald did that by himself.
Texans were never fans of any of the Kennedys, but we consider it a black mark that it happened in Dallas. The reason that Johnson was "forced" to run on the ticket with JFK was to balance out that anti-Kennedy bias here.
I find it curious that anyone would believe the Mafia could have been the ones who were at the top of the conspiracy to kill Kennedy. Sure, Mafia members could have been the people who pulled the trigger(s) but the people who killed him had extraordinary power to alter evidence and lead investigations into delivering BS, not truth.
In this clip on YOUTUBE, Ruby says there were important people that will never let the truth out AND he says Kennedy would never have been killed if we had a different VP, Ruby then goes on to say IT'S THE MAN IN OFFICE NOW. The last two segments in the video were later before Ruby came down with cancer. START watching at about about 3 min 10 seconds for RUBY.
We are talking about this topic because it is the best example there is of the American news media filtering the truth. Bet you've never seen before the clip of Ruby saying it was LBJ.
