that article on the JFK assassination...

after watchin the video, I think its quite clear he was shot from
behind. his skull blows off to the front. his head goes slightly
forward (bullet entry from the rear) and then violently backwards
(after hte bullet escapes to the front, forcing the head back because
of the bullet's exit force)

i know Mythbusters re-enacted it with a shooter in the rear which had
basically the exact same results.

not sure what foundation conspiracies have.

though, I will say, to be able to have that kind of accuracy seems
like you'd ahve to be an extremely skilled shooter...even if the
vehicle is moving basically in a straight line away from you. perfect
line of sight.
