RS-
Yes, Gov. JBC's surgeons believed a projectile entered the "dorsal" (wristwatch side) of his right wrist, fractured the bone, and then exited the "ventral" side.
Surgeon Shaw thought that wound-pattern indicated a separate projectile had struck JBC's wrist. Shaw thought the SBT could have happened, but leaned towards JBC being struck by a separate shot from JFK, and was additionally puzzled by JBC's wrist wound.
You can sit in you chair and try to face the dorsal and ventral side of your wrist to your chest. It takes a bit of contorting to get the dorsal side to face your chest.
Even CT'ers seem little informed about these oddities regarding JBC's wounds. (In truth, most CT'ers prefer to chase ideologically informed narratives that comfortably explain the JFKA in its entirety, not hard facts).
I lean to towards more than one shooter on 11/22. But given that no one has ever determined who LHO's confederates or manipulators were...who knows who they were.
I suspect a very small plot, possibly two Alpha 66'ers, or G2'ers.
Suspicions, like allegations and accusations, are not facts.
