It looks like the left hand has moved toward the chest from z224 to z225.
His
left hand has fractionally moved upwards, towards his chest. It is down by his side as he passes behind the Stemmons sign and it is in the same position, down by his side, when he emerges from behind the Stemmons sign in z224. In z225 there is the first hint of the movement that will have his
left arm rocketing up to an incredibly extreme physical position.
The pic on the left below shows JFK's
left arm position at z183, before he passes behind the Stemmons sign. The pic on the right shows the
left arm in the same position after he emerges from behind the Stemmons sign, in z224.
From the resting position, down at his side, JFK's
left arm suddenly rockets upwards into a really extreme physical position. His elbows are extended upwards to, what appears to be, their fullest extent. I would urge any reader of this to replicate this position to get an idea of how extreme it is. Even more extreme is the amount of time it takes his
left arm to go from a resting position into this extreme posture - it is a fraction of a second.
It is surely a rapid reflex reaction to damage caused directly to the central nervous system by the bullet that transits through JFK's neck. 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 z224 JFK's
left arm is down by his side yet at z232,
half a second later his
left elbow is thrust up to what appears to be it's maximum extension (as I say, try replicating this position, I know I can get my left elbow barely any higher than JFK's and that's really trying).
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?:
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. I believe there is a first hint of movement seen in z225.
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 of the Brachial Plexus - the nerves that control function of the arms and hands - that the bullet is known to have passed through.
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.
IT IS ALL SHOWN IN THE Z-FILM.
Ultimately, you are correct - JFK's
left arm does show a sight movement in z225.
But I'd already pointed that out.
Jackie turns her head from looking left in z173 to looking somewhat right by z193 looking toward the crowd on the right but not looking at JFK. She then turns farther right until about z212 so that she is looking right at her husband (seen by her hat in z212) and holds this position after she emerges from behind the Stemmons sign:
Again, I'd already pointed that out.
Thanks for agreeing though.
