Shall we have a battle of questions that no one answers? You might find it instructive to respond to things that were actually said For example, their is no mention of explosive head wounds to which you responded with references about explosive head wounds Just sayin
You are constantly moving the target. The issue is whether the rearward motion of JFK's head after z313 could be caused by a shot from the rear causing an explosive exit wound that sent matter forward from the right front of his head. You said that the Edgewood experiments disproved Alvarez ( ie. disproved his contention that the explosive head wound is consistent with a shot from the rear and that, based on the laws of physics, this forward ejection of matter could explain the rearward motion of the head as recoil from that explosion). I asked you how they that could be the case, suggesting that there were no explosive wounds from the goats shot at Edgewood. You seem to want to avoid the details.
