Check the Zapruder film https://en.wikipedia.org/wiki/Zapruder_film
It shows the shot to his throat and his head going backwards which indicates a shot from the front.
People laughed off and ignored the Grass Knoll theory for years but I think the new files kind of prove that it may not be a theory.
The physics shown in the Zapruder Film prove the fatal shot came from the front/right of the President. (Talk of muscle spasms and the back brace etc can’t negate what is shown in the film.) The tissue sprayed onto the trunk and onto the motorcycle cop at the left/rear of the limo does the same thing. The piece of JFK’s skull (Harper fragment) found in the grass to the left of the limo’s position at the time of the head shot does the same thing. The majority of the doctors who saw the throat wound before the tracheotomy say it was an entry wound. These were ER doctors who saw gsw all the time. These physicians knew what they were talking about.
I don’t think Oswald fired a shot that day.....JFK or Tippitt. I think he was exactly what he said he was......a patsy.
