As I said, I won't argue for or against any theory. I would just urge you to take into account the relative positions of the objects in question: The window height and location. The way the president's head was bent forward and his body was somewhat slumped down and to the left after the shot to his back/throat, and so on. Look closely at the frame-by-frame scenes of the head shot above. Fit fact to whatever theory you have of the murder, not the other way around.

You're right, I didn't pay attention to that. His head being slumped foward when hit would've produced a plane like the wax mock up shows.
