I’m not here to convince you. Believe whatever you want, I don’t care.
The evidentiary chain was destroyed at the time. All we have is inference and hearsay.
Pictures taken by members of the public who were very close to JFK at the moment he was shot were confiscated by persons identifying themselves as FBI, and never returned to their owner after promises being given to do so.
There is considerable evidence by people who were present in the room that the autopsy was interfered with. X-rays of Kennedy’s head, and other evidence like tissue samples were stolen. Kennedy’s brain wasn’t present in his skull at the autopsy table.
All evidence collected by the Dallas PD was handed to the FBI at the time, by the direct order of J. Edgar Hoover. It disappeared.
Oswald’s palm print only appeared on the rifle after he was dead. The undertaker who prepared his body for burial let a bunch of men in suits in to the room where he was lying the night before he was buried. After they left, he had to clean ink off Oswald’s fingers and hands. He had already been fingerprinted by the Dallas PD, when he was processed into custody.
But believe what you want. Doesn’t matter to me one way or another.
Fair enough but none of that satisfactorily explains where the shooter was if he wasn't in an elevated position to the rear of the presidential limo.
