@Jerry: I’m generally in agreement with LNs about the Z223 SBT because of the simultaneous movement of JFK and JC.
I just disagree that the bullet was CE 399. Imo it was a more pointed shaped bullet unlike the ball
shaped 6.5 mm MC bullet.
My point about JCs right hand is that there is really no way he could have been hit in the wrist of his right hand after Z225 because he’s then holding up his right hand with the hat being gripped tightly.
At the point with way his hand is up gripping the hat, there’s a high probability there would not only be some blood splatter from the bullet exiting his palm, but there would be a HOLE in the hat !
So because there’s no hole and there’s no blood found on the hat ( at least not visible) then it seems to me that it’s no choice here for a CT but to accept the most probable way that wrist wound occurred was while the hat was being held over the JCs left leg which imo was rotated approx 45 degrees clockwise ( towards right side door ) so that JC wouldn’t have his knees jammed in the back of Kellerman.
