Instead of your lazy and increasingly tedious insults answer the question of what happened, you have the same information as us?
a) both men react simultaneously
Well, we can't be sure how simultaneous the reactions began because JFK could have begun reacting behind the Stemmons sign. The HSCA panel thought he began reacting before he disappeared behind the sign. He appears to be already reacting with his face and hands when he is first seen in z224. Besides, it is readily apparent from the testimony of JBC himself, Jackie and Nellie that he did react to the shot that struck JFK - the one that witnesses said caused JFK to react by moving left/bringing his hands to his neck/assuming a blank look. It is just that JBC said that this was not the shot that he felt hit him in the back.
b) both men are lined up perfectly with the 6th floor snipers nest window.
It is hardly perfect. JBC has to be about 13 inches left of JFK for the trajectory to work. At z222-224 JFK's hands would appear to be in the path of a bullet from his throat to JBC.
c) the amount of lead missing from CE399 is virtually equal with the tiny pieces found in Connally's wrist
No one knows how what CE399 initially weighed exactly. The damage to the radius was severe. The radius is one of the hardest and strongest bones in the human body. More to the point, Greer felt a concussion from the second shot and Tague said he was not hit on the first or third shot and there were only three shots. It that is true, that means that a considerable fragment from the second shot left the car.
d) the rear entry on Connally was linear meaning that CE399 passed through something first to cause tumbling.
The rear entry on JBC was elliptical, not linear and it is symmetrical. This is inconsistent with a tumbling bullet whose entry profile would necessarily be non-symmetrical.
e) CE399 was not pristine and showed heavy deformation on one side indicating that it struck primarily side on.
"Heavy deformation" is a bit of an exaggeration. It was pushed in on the base only. That is consistent with striking the thigh butt-first which is how Dr Gregory described the cause of the thigh wound.
f) as the bullet passed through Connally it caused less and less damage, a full on bullet shatters bone but Connally only had a fractured wrist.
??What about the complete obliteration of the last 10 cm of JBC's fifth rib? The bullet pentrated and destroyed that rib sending bone shards into lower lobe of the right lung. What about the "tunnelling" wound path that Dr. Shaw described? What about the multiple fracture of the radius - a very hard bone?
