You've seen the reaction already in Kennedy, his arms are up. According to Specter's single bullet theory Connally by this frame has already been shot to pieces yet there is no reaction.
Why do you continue to ignore JBC's right arm flip which began at the precise moment JFK's arms went upward. I think that's called willful ignorance.
He is still holding his hat in the shattered right radius of his arm.
The only reason you can see him holding his hat in his hand is because his arm has flipped upward.
Kennedy reacts but Connally is superman?
Both of them reacted in much the same way, by flipping their arms upward. Immediately after the arm flip which lasted about a half second, JBC turned and dipped dramatically to his right. Once one recognizes JBC's obvious arm flip, one realizes there was no time lag between when they both reacted to being shot.
John and Nell Connally both testified that the shot which hit Kennedy came before the one which struck JBC and this frame proves they were telling the truth.
If you took this frame/photograph to a modern forensic pathologist and told him/her that Kennedy was shot sustaining one injury and JBC at this point had sustained multiple life threatening injures - you'd be laughed out of the building and I've met plenty of pathologists.
Give it up, the joke is over.
John Connally had no way of knowing whether JFK had been hit by the first or second shot. Nellie could not have observed both her husband and JFK at the same time. She first turned and saw JFK had been shot, then turned back to see JBC had been shot. This gave her the false impression that they had been hit by separate shots.
