No, ever been there? It is not a head on shot from the grassy knoll. I have been there 20 times.
And there is a group of experts from Australia that duplicated the shot. The very first time they tried it from a perch with the correct height. I have been in the window next to it. It is not that much as a deflection.
Been there and filmed it from a car moving same speed as well as from book depository. We teach long range shooting and the shot from the book depository is far more difficult than the grassy knoll. Also read the depositions from the Warren Commission by the doctors who took care of him. The primary questioner was Sen Arlen Spector. Every one of them describes a large occipital wound ( back of the head) with massive brain damage. Everyone of them was either faculty at Parkland hospital or surgical trainees who later became Professors at UT Southwest (Parkland), which was the premier trauma hospital in the US, or at Cornell. Not people who would miss that kind of detail. This would be more consistent with an exit wound in the back of the head.
