I believe it was the Secret Service agent trailing Kennedy’s vehicle that accidentally fired the fatal head shot with his AR-15.
Not feasible. For that to happen the CIA agent would have to stand, lift the gun up into open view, and fire right over the head of the driver and the other CIA agent in the passenger seat. It would have blown their ear drums out.
i have heard that as well.. the SS stood up when he heard the shots the cars accelerated and the gun went off..
