There are a lot of people on this board who disagree with you on the first shot hitting JBC in the back.
A lot of people on this board think very different things - a shot before Zapruder starts filming, 6 or more shots, shooters in storm drains/on the Dal Tex/ in the follow-up car etc. etc. The point of this forum, as far as I'm concerned, is to put up your beliefs regarding this case for testing by other members. That's what I've done from day one but I've noticed that only a fraction of the members seem willing to do that and many would rather have their beliefs untested.
Most accept that JBC's recollection of being struck on the second shot is reliable and accurate.
I have no way of knowing how you know this but I instinctively don't believe you know this and that you are willing to make such unreasonable statements to support your own views. I think you should keep it to what you believe rather than trying to bring in everyone else. If they wanted to join in they would already have done so.
If that is the case, as I suggest the evidence shows, then the second shot struck JBC at around z270. That is just an inevitable consequence of the 1........2...3 shot pattern.
The following clip refutes your belief regarding a second shot at z270:
Here is a close up of the same clip:
You may think it's reasonable to gloss over this unequivocal evidence that you are wrong on this point but it's not. To imagine a bullet is exploding out of JBC's chest at this point, and smashing into his wrist is, in my opinion, totally unacceptable. I know if I was faced with such unequivocal evidence I would change my mind, which is exactly what I've done on more than one occasion.
So don't tell us why there can't be a shot striking JBC at z271. Show us the evidence that JBC was hit on the first shot. Perhaps you can explain not only why no one observed him hit on the first shot but why it is that the witnesses who observed him being hit said he was hit on the second (Connallys, Newmans, Dave Powers) and why that is independently corroborated by others such as Hickey and Greer.
Before we got into contradictory witness statements of the Connally's I presented argument after argument concerning the complex of sudden, extreme and incredibly rapid reactions both JFK and JBC both undergo at exactly the same moment, demonstrating both men were shot through at the same time. You struggled with this section of the thread but once we got into the vague, contradictory nature of eye-witness accounts, you came alive.
The fact is that several witnesses said that JBC was hit on the second shot. None said he was hit on the first. The zfilm is equivocal. If it was unequivocal that JBC was hit in the back on the first shot, you would not have reasonable people on this board disagreeing with you. Even Jerry disagrees with you on that point.
Back to your old tricks I see.
I've never said the Z-film was unequivocal regarding JBC being hit in the back on the first shot because it's not. I've compiled a series of of arguments based on observations of various extreme and rapid reactions shown in the Z-film.
However, the Z-film is unequivocal when it comes to refuting your supposed shot at z270.
(BTW - Jerry agrees with me that your model is over)
That is evidence that something penetrated the wrist but it is not evidence that CE399 penetrated the wrist. The projectile that exited his chest struck the back of his french cuff about 1.5 inches from the end of the cuff. Yet it did not make any exit hole on the palm side of the cuff where the slit in his skin was located. Perhaps you could explain how that could occur. When you have done that, perhaps you can explain how it ended up making a nice round oblique hole in his left thigh along the direction of the femur.
The entrance wound is a lateral wound a few inches away from the base of the thumb. This area is covered by JBC's cuff.
The exit wound is a much smaller wound near the creases of the wrist. In the pic below we can see that this part of his hand is not covered by his cuff:
That is why there is damage to one side of his cuff and not the other. You seem to imagine it is a through-and-through wound and that it should appear on the other side of his cuff. It's not, the bullet/fragment travels 'diagonally, up his arm to his wrist.
The fragment blown out of this wound hits the inside of his left thigh.
It is just the natural path of a bullet exiting JBC's chest below the right nipple at z271. How does a bullet deflect around the radius after striking the radius so forcefully?
It's a glancing blow when it suits you and a forceful blow when it suits.
JBC's right arm is holding his Stetson in his lap when he's hit in the wrist, hence the 'diagonal' nature of his wound. I believe the bullet fragments on contact, some deflected away from the wrist, some metal fragments stuck in his wrist and at least one significant fragment blowing through his wrist and into his thigh. Nothing deflects "around the radius".
