I don’t know how old you are, but I was 10 when JFK was killed. We were all told Oswald killed him and what could a 10 year old believe except what the authorities told me. Years later I saw a tv segment where they had what was considered their expert marksman/shooter. In the Zapruder film, 3 shots were heard. Whether or not Oswald was on target, this marksman could not fire Oswald’s rifle 3 times in the time frame. It was bolt action and a piece of junk. This was all I needed to realize there was another gunman. Who did it? I believe it was a mafia hit because they leave no loose ends…Ruby shooting Oswald, and the Kennedys didn’t get along with the teamsters and Bobby was AG. They got him down the road. My whole life I’ve wanted to know but it’s been so long now, like you said, it won’t make any difference, except if it was a CIA hit, it would make the government look bad. Oh well, anybody involved is surely dead.
