Zapruder and the Newmans in their first day interviews describe a head explosion exactly as seen in Zapruder's film which shows matter going forward and away from Oswald's rifle and this same wound location is seen in the Autopsy photos and the Xrays. Why is this still even being discussed?
Kennedy's head moves forward.
The back of Kennedy's head shows a bullet entrance.
Besides the total absurdity of having a shooter out in full 360? public view who could be easily seen or photographed by a plethora of cameras in Dealey Plaza, then you try to setup a Patsy who was directly behind and 6 stories up? If it was me then I would pepper the upper floors of the buildings behind with snipers but putting a sniper in front or wherever at ground level in full view of anyone who cared to look is totally illogical and simply would never happen.
