IF it came from the front.
PROVE IT.
One only needs to look at Kennedy’s reaction and where the half of his head ended up for proof. You can’t duplicate that shot from the rear. I’ve tried many times with various objects (obviously not heads, but other things ranging from an old football to cantelope) and with several calibers of rifles, ranging from rimfire .22s to .308s.
I can do it easily from the angle suggested by the picket fence.
Oh, and saying “front” is misleading. Read my post on the Hill testimony. He said “right.” Given the angle of the car at the head shot impact, it is much closer to a right angle than to a “front” angle.
Jesus.
It's just not worth it. Even the majority of wild eyed conspira-buffs don't even take that position anymore.
