Some people say Gov. JBC was shot through the wrist while holding his cowboy hat.

The image above is Z-223. JFK was likely shot ~Z-220 in his upper back.
OK, JBC does not look injured, although, according to the SBT, a slug has passed through his chest, taking out part of rib, exited his front, leaving a large gaping wound, then entered the dorsal side of his wrist and fractured it, before penetrating his left thigh.
I don't see JBC's gray cowboy hat in Z-223, unless it is the blue-ish (not red!) smudge on his chest, below the tie of the necktie. If that is cowboy hat, then JBC is very likely holding it with the ventral side of his wrist facing his chest.
Could a bullet have passed through the wrist holding the cowboy hat, and then entered his left thigh? The wrist seems too close to the right side of JBC.
How did the bullet pass through JBC's wrist from the dorsal (wristwatch side)?
At Z-227, JBC appears to holding his cowboy hat in front of himself, although the image is blurry.

Something doesn't add up about the SBT.
