You sound like Bugliosi.
I am aware of all these "excuses", fairy tales and other "explanations".
If you watched the video you saw that Connally's head snaps downward faster than anyone could move it (2 frames, approx 1/10 of a second) and you continue to repeat Bugloisian explanations. That is the point the bullet hit him in the back. Dale Meyers is famous for the lapel bulge at Z224 but that is NOT the point the bullet hit him in the back. Connally simply raises his shoulders as he snaps around to look to his left then he snaps around to look to his right which is where he thought the shot was fired from.
For FIVE SECONDS Connally turns, no sane person could believe that he has a major back/chest wound and he'd turn like this. He isn't shot in the back until 5 seconds later. That's why this is a mystery, too many witnesses disagree witht the "official" findings which are nothing but bundled lies.

Bugliosi is an experienced criminal lawyer. He knows how to evaluate evidence.
It is a fact that there are other possible explanations. Witness perceptions are not gospel. The human mind is not a recording device.
