Sorry I don't fit your tortured profile, but I don't believe incomplete investigations, suspicious autopsies, disappearance of evidence and on and on.
It is easier to believe that there was something going on beyond this one guy pulling the trigger than to believe the official version.
I believe when JFK said he thought the Cubans did it and he wanted the Warren Report to get there work done to allay the fears of Amercians, that they was just as easy a misdirection as it was anything else. I don't know how we can know what we know about LBJ and dismiss his "need" to become president.
Also, it's easy to believe a death bed conviction of a man who was not home on the day even thought he told others he had been. His own family denied that.
Maybe other family members will come forward and debunk their son/brother, but his story is more believable to me than the "official" story.
BTW which one IS official, Warren or the 2 congresional investigations?
Watch the Zapruder film. As JFK is leaning forward, the last shot took off the back of his head. His head is flung back, while everyone else is stationary.
In one of the AP pictures that show SS Clint Hill climbing on back of the Presidential limo, you clearly see a bullet hole in the front windshield. (The windshield was later removed from the limo. )
I am not into conspiracies, but the idea that the shots all came from up and behind seems to defy logic and physics.
Actually you’re right though... America hasn’t been tortured by the shootings. That is a bit of theaterics by the author.
