I thought I had seen most photos of Dallas. But I found this one in a video. It's a pretty good likeness of the body positioning of the victims before the shots.
So I ask - how in the world could a bullet be coming from a downward angle, moving right to left, it hitting Kennedy's back (and of course Humes said that wound terminated mid-body) and then make a clean pencil-thin exit in the throat - when Kennedy's neck was turned to the right like this photo?
It seems that a bullet exiting from the throat (from a, ahem...terminated back wound) would have made a tear in the throat vs a pencil thin wound as described by the PMH doctors.
