I agree that Secret Service accidental-shooting theory explains some otherwise unexplainable things. However, is there an explanation for why when the accidental shot came from behind that the large piece of Kennedy’s skull flew backwards onto the trunk lid of the limo? Seems far more consistent with a shot coming from the front.
My understanding is that the bullets ended up in the front seat area. Without evidence of ricochet, could not come from front/face side shot.
