the TV piece Bobert refers to had LOTS of interviews that purport to show that autopsy photos were doctored to totally remove evidence of the exit wound in the back of the head that 20-30 people swore they saw, and OTHER witnesses who SAW the limosine being 'fixed' at Ford and the bullet hole in the front window conveniently disappearing...pretty compelling...yet, Oswald was running from the law and shot a policeman and had hidden a recently fired rifle in the depository. And tests have been done showing that a decent marksman 'could' have hit a head from that 6th floor..

I honestly suspect that there was stuff covered up, but barring some new 'confession', we will just all continue to speculate...Did LBJ 'allow' and help cover up all this?...maybe..*shrug*
