Go by your own eyes please. I have an extremely graphic video that I could share with you on here that shows two men, taking a high-powered bullet to the back of the head and NEITHER of them are slinged backward. Taking away all of the scientific mumbo-jumbo (jet effect, acoustics, etc.) this is more than enough proof - at least for me - to me that someone taking a shot from the rear does not suddenly be slinged backward. It doesn't make sense and if you're honest with yourself after seeing it, it should put doubt into even the most rabid LNer.
I would post it for educational purposes only here but I do not know if the admins would allow it and I don't know who to ask. When I posted it many months ago on EF, some people were shocked but nothing was reported. Then months later a member there, Stancak, got pissed because I kept rebutting his stupid PM long-leg theory. When he came across the video, he suddenly became ultra-sensitive ("oh my goodness") and reported it. Then, irony of ironies, he posts Kennedy's graphic autopsy photos.
