This is beyond silly.
So silly you have no answer to the conundrum you have created by suggesting that JBC's sudden arm flip preceded his wrist being shot by 3.6 seconds. I've noticed that when illogical CTs such as yourself are confronted with the illogic of what they have proposed, their standard reply is to make a dismissive response such as "This is beyond silly" without ever addressing the point they are asked to explain. You have no logical response, so you resort to bluster.
You have no clue what you're talking about. If you would ever dare yourself to read just some of the scholarly refutations of the SBT, you would quickly discover that they have explained in great detail why the theory is preposterous.
"Scholarly refutations of the the SBT" are like unicorns. I've never actually seen one.
Perhaps in your dreams. BTW, which SBT do you accept? The one that has the bullet entering at C7 or the one that has the bullet entering at T1? The one that has the bullet traveling at a downward angle or the one that has the bullet traveling at a slightly upward angle? The one that has the bullet hitting JFK above the alleged exit point or the one that has the bullet hitting JFK slightly below the exit point? The one that has Connally rotated to the right by 10-15 degrees or the one that has him rotated to the right by 20-30 degrees? The one that has the magic bullet as the first shot or the one that has it as the second shot? The one that has the bullet hitting JFK at Z188-190, or the one that has the bullet hitting JFK at Z221, or the one that has the bullet hitting JFK at Z224? The one that says JFK shows no signs of reacting to the wound until Z226, or the one that says he is already reacting in Z225, or the one that says he begins to react at Z200?
I have no answer for questions based on false pretenses. The bullet entered JFK's upper back approximately two inches right of JFK's back. The location is shown in one of the leaked autopsy photos. The bullet exited JFK's throat at the level of the knot of his necktie. It tumbled upon exiting and struck JBC who was sitting in front of and slightly to the left of JFK. The bullet entered in the back near his right armpit making an elongated wound due to the tumble. The bullet exited below his right nipple and passed through his right wrist, depositing tiny lead fragments from the core which was only exposed at the base of the bullet.. The bullet went on to make a shallow penetration in JBC's thigh before working its way loose and was discovered at Parkland hospital and become CE399.
Just for once, do a modicum of balanced research and educate yourself:

These three articles are nothing more than a collection of stale old myths, misstatements of fact, and your amateur analysis of the medical evidence which is at odds with the conclusions of the FPP, which concurred with the SBT with the lone dissenter being Cyril Wecht. A classic example of garbage in, garbage out.
