I don't know how you can tell that JFK's right arm is down by his side before he passed behind the sign. It may be. But all I can tell is that it appears to be lowered and even that is not entirely clear. If at z204 it was in the same position as we see it in z224 then he was already reacting by z204 because that position in z224 is not normal.
I don't know if this a deliberate strategy on your behalf or you're just not reading what I'm posting. Just to clarify, at no point anywhere do I say JFK's right arm is down by his side. It is absolutely clear from the Z-film that JFK's right arm is resting on the limo door as he passes behind the sign and as he emerges from behind it.
The point I was making was about his
left arm/hand but you have decided to create a false argument talking about his right arm being down by his side when I was clearly talking about his
left arm being down by his side. You seem to think it's not entirely clear in the Z-film but if we have a look at the two pics below we can see it's clear enough:
The pic on the left is from z183, before JFK goes behind the sign, the pic on the right, taken over two seconds later, is from z225, just after JFK emerges from behind the sign. In both pics I would like you to focus on JFK's
left arm/hand. It is down by his side, the bottom part of the arm is hidden by the limo door, the left hand is resting around the stomach area. This much can be clearly seen.
Going back to my earlier post, let's take a look at the Z-film showing JFK before he passes behind the sign.
As he passes behind the Stemmons sign JFK is just finishing a wave and it can be expected that his right hand would be in such a position as he emerges from behind the sign. As such, the right hand is an unreliable indicator of his reaction to being shot. In order to get a more accurate read on his reactions it is necessary to focus on his left hand/arm. The footage below (z169-226) shows JFK's last wave. It starts with his right arm resting on the side of the limo, elbow out, with his right hand reaching back into the limo holding his left hand, which appears to rest on his stomach area, his left elbow down by his side. He releases his left hand as he begins to wave with his right. His left hand stays resting on his stomach area, his left elbow down by his side. His left arm/hand stays in this position as he goes behind the sign and is still in this position as he emerges from it:It is perfectly clear in the clip above that as JFK begins to wave with his right hand his left arm stays down by his side, his left hand resting near his stomach area. This is perfectly discernable. In the pic above from z225 we see his left arm/hand is in exactly the same position as he emerges from behind the sign. The importance of the position of his left arm/hand will soon become apparent.
We both agree that the first shot strikes JFK, passing through his throat. JFK's reaction to this shot is quite startling - his hands clench into fists which he jams under his chin area as his elbows fly up in the air in quite an extraordinary fashion, his whole upper body becoming temporarily rigid before relaxing slightly. It is a really extreme and rapid reaction:
It really is an extraordinary and profound reaction. There can be little argument it is a reaction to being shot. The pic below shows how extreme the reaction is:
This pic is from z232. As we have seen, at z225 JFK's left arm is down by his side yet at z232, less than half a second later his left elbow is thrust up to what appears to be it's maximum extension (try replicating this position, I know I can get my left elbow barely any higher than JFK's and that's really trying).
Less than half a second to get his left elbow from a resting postion at his side to, what I am assuming is, it's maximum extension. Trying to do this with a conscious effort is barely possible but in JFK's case, this is done from a resting position with no expectation that this reaction will be happening. From a completely relaxed state to rigidity in less than half a second.
So when does this extreme reaction begin? Let's return to my earlier post:
In the clip below (z224-226) we see his left hand still resting on his stomach area, his left elbow down by his side but obscured by the top of the limo door (z224). In the next frame there is a slight movement of his left arm and hand (z225). In the final frame his elbow comes into view from behind the limo door, his hand clearly moving to his throat (z226):
It is clear from the above frames that this extreme movement of JFK's left arm can be seen most obviously in z226, when his left elbow, which has been hidden from view by the limo door up to this point, suddenly comes into view. We can say with little doubt that JFK's extreme reaction has begun by z226. Elsewhere I've argued that the very first reaction begins at z225 (JFK's "Hand Snap").
The Z-film shows an extraordinary and extreme reaction to being shot. It begins at z225. Before this point in the film there is nothing - absolutely nothing - that even hints at such an extreme reaction. As JFK begins his last wave he turns and smiles towards the people to his right. His finishes waving and is bringing his hand back down and turning slightly forward as he passes behind the sign. Perfectly normal actions. His left arm is down by his side for, what may well be, the duration of the Z-film from z133 to z225. Within less than half a second his left elbow rockets up from a relaxed position down by his side to it's maximum extension. I believe it is a reflex reaction to a massive trauma. I also strongly suspect that the bullet which passed through JFK's body may well have severed a nerve that runs the length of his arms down into his fingers.
Whatever the case, there is nothing in the Z-film that is remotely comparable to the extreme reaction to being hit by the first shot prior to z224. Arguments about slight head turns or what might have gone on behind the sign are redundant as we get to see the full extent of JFK's reaction by monitoring the position of his left arm.
I present more evidence and arguments that support this conclusion but that's enough for now.
I hope I've convinced you that this rapid and extreme reaction could not have come from a hit two seconds earlier, which is an eternity when considering such reactions
