I say it fits the zfilm. It just doesn't fit what you think the zfilm should show if JBC was hit in the back and wrist at z271-272.
Well, it does not show what you think it should show if JBC's wrist was shattered at z271-272.Physically impossible? Not if the bullet deflected on hitting the fifth rib. Keep in mind that it did not penetrate the rib where it struck it in the back. That means it deflected and followed the rib until the last 10 cm of the fifth rib. Then, it passed through the rib and exited just below the right nipple. On exiting the chest it struck the right wrist that was then pressed into the chest. It deflected off the back of the wrist (ie. to the left) It did not exit through the french cuff on the palm side of the wrist.
How could the bullet not have made a hole in the palm side of the cuff similar to the hole in the dorsal side if it exited the palm side of the wrist? And how does it deflect over to the left side? How does it deflect around the point of contact on the radius?
Dr,. Shires thought the bullet hole in his thigh could have been made by a pristine bullet if it hit at an oblique angle. We don't have enough evidence to say anything more than that the trajectory from the SN through JFK's neck to JBC's left side works. And the wound in the thigh is consistent with having been made by the butt end of CE399. If we knew exactly where and how the bullet fell out of JBC, I would have a better answer for you.
It is not all that rapid. It moves from slightly above the edge of the car to out of sight in 55 ms. So it moves maybe as much as 3 inches in 55 ms. which is about 55 inches in a second. I can move my arm that fast quite easily. It looks to me like JBC is moving his arms so he can turn around to see JFK. That's what he said he did. And that is what he does immediately after. The Newmans saw him turn around to look at JFK after the first shot and before the second. After the second, they observed him holding his stomach and falling back.
I have. Several times. It doesn't bulge. The lapel moves. In z224 the jacket looks very similar to z222. The question is what happened between z222-223 and why did it go back to looking like z222 in the next frame? The obvious answer, is that the jacket moved or it was a combination of jacket motion and shadow.
"I say it fits the zfilm."This shows the moment you believe a bullet, deflected at an impossible angle through JBC's body, exits his chest, shatters JBC's wrist, leaves metallic fragments in the wrist and two of the fragments then go on to cause crack the windshield and dent the chrome trim in the front of the limo (in the Z-film, neither Greer nor Kellerman show any kind of reaction to what must appear to be 'a flurry of shells' coming into the front of the limo. The 'ducking' reaction both men perform after the headshot is clearly the moment the 'flurry of shells' hits the windshield and chrome trim)
Problems with your proposal:
1) The impossibility of "no movement" - taking the blur into account, JBC's wrist doesn't move one inch. The massive impact doesn't move any part of his hand in anyway. Remember, in your scenario, without any evidence to support it, you insist JBC's wrist is somehow compressed against his chest, this is something you've never bothered to really explain. If you are trying to say his wrist is trapped between his chest and the back of his jump seat, it is yet another example of the physical impossibilities you are happy to include in your model. For his wrist to be trapped in the way you suggest JBC's body would have to be facing directly towards the back of the limo. Even then, such a massive impact would cause movement in his wrist because, as you seem to be deliberately unaware of, the hand can rotate on the wrist, the hand and arm are not one stiff unit. In the scenario you are presenting JBC's arm and hand need to be somehow trapped against an object not visible in the Z-film.
2) The impossibility of the fragment trajectory - in your model, the bullet exiting JBC's chest should travel straight through JBC's wrist, side-to-side. While JBC's shirt and Jacket sleeve have a hole on one side, they don't on the other which they should if the bullet/fragments travel directly through the wrist. You explain this apparent anomaly by saying the bullet fragments against his wrist, with some of the larger fragments flying off to cause the damage to the front of the limo. When we look at the Gif above, the impossibility of what you're suggesting becomes apparent. In it we see the back of JBC's bare wrist is higher than the part with the cuff, his hand compressed against his chest (according to you and no-one else). The fragments of the bullets deflecting off JBC's wrist and moving in the direction of the front of the limo, would not be able to pass JBC's hand pressed against his chest. It's impossible.
3) The impossibility of the injuries - As touched on in the last point, the bullet exiting JBC's chest would pass directly through his wrist side-to-side. However, the actual injuries to his wrist demonstrate the bullet/fragment entered his arm a few inches above his wrist and exited at the crease of his wrist. It has not travelled side-to-side but "diagonally" from higher up his arm to the wrist crease. This kind of injury is impossible in your proposed model.
Regardless of all the physical impossibilities you have to overcome you will carry on regardless. You have no choice.
And these are only some of the physical impossibilities your model is entertaining.
How is reasonable debate possible?
