JM--
BTW, the tumbling theory SBT is entirely dead, and I am the man who killed it.
I found this photo of Gov. JBC's assassination-day shirt:

At:
https://www.tsl.texas.gov/sites/default/files/public/tslac/landing/documents/jfk-damaged-clothing18.pdfA small round hole in the rear of JBC's shirt. Like a direct shot, no? A tumbling bullet did not make a small round hole in JBC's shirt.
Again in a nutshell, JBC says the shot that struck him pushed him forward.
Connally: I was knocked over, just doubled over by the force of the bullet. It went in my back and came out my chest about 2 inches below and the left of my right nipple. The force of the bullet drove my body over almost double and when I looked, immediately I could see I was just drenched with blood. (1 HSCA 42)In addition,
both JBC and his wife testified: first shot hit JFK, then JBC turned to look, began to turn forward, second shot hit JBC, and third shot hit JFK. All that happens in the run-up to ~Z-295.
Then we have testimony of Dr. Robert Shaw, JBC surgeon who had worked on 700 military war-time gunshot victims. Shaw thought the shot that had struck JBC likely was unimpeded by anything (straight shot).
https://www.history-matters.com/archive/jfk/wc/wcvols/wh6/pdf/WH6_Shaw.pdfShaw also found inexplicable the wound to the dorsal (wristwatch) side of JBC's wrist, as confirmed by Dr. Gregory (Connally's wrist surgeon). In other words, the bullet entered JBC's wrist about where a wristwatch face would be, and exited the dorsal (opposite) side. Try holding your wristwatch face in front on your navel to get an idea of some problems presented by this awkward scenario.
Anatomical Implausibility: Shaw expressed doubt (to the HSCA) regarding how a single bullet could transition from the Governor's chest into the dorsal (back) side of his wrist, suggesting it would be anatomically difficult for the Governor to have held his arm in such a position.--AI
Like others, I have looked at the Z-film many times. I just do not see any sign that JBC is in severe pain after in the frames following Z-222-225. He may look startled, or he may look like nothing.
However, JBC
indisputably makes a 180-degree in his seat to look for JFK
after Z-225, around Z-265.
So, if JBC was struck by the same shot that struck JFK, he then made a 180-degree turn in his seat...after being shot through the chest, and having his right wrist shattered and a slug burrowing into his left thigh. That is the SBT contention.
For me, that does not hold water.
Then, we have the "bang....bang-bang" sequence most earwitnesses heard. That lines up better with my scenario.
The shot to JBC's wrist remains a curiosity--a shot from the GK? I don't know.
PS. This is a picture of the exit hole in JBC's assassination-day jacket. The bullet did not exit through the lapel.

Hey, just IMHO.
