He goes from smiling and waving at z193-z196 to a very different position and expression in z224, a time span of about 1.5 seconds:
I am not alone in seeing a material difference. It is inconceivable that if he was hit at z222/3 while smiling and waving that he could have assumed the position seen in z224 (particularly since his hands are already in the same place in z223). The fact that it occurs very close to the time of the first shot leads to one of two conclusions: 1. he is reacting to being shot earlier 2. he was bracing himself for the shot before it hit. I would suggest 1. is the more reasonable.
You're having one of your 'senior moments', Andrew.
The post you were responding to was about John Connally, not John Kennedy. JBC, not JFK.
First of all, Itek is interpreting just the film with the knowledge that Connally had been hit. I do not see that they were aware that he said he and Nellie said he was hit in the back by a different shot than the one that struck JFK. I do not see that Itek was aware that the Connallys said that JBC reacted to the first shot, that did not hit him in the back, by turning around to check on JFK. I also don't see where they have any expertise in identifying what a reaction to a chest bullet wound should look like let alone what this one should look like.
The Itek Corporation are specialists in photographic analysis, no less than five photo analysts examined the Z-film and all, independently, came to the conclusion "that somewhere between 223-226 there are signs of the beginning of a significant change in the governor's position and appearance".
You'll excuse me if I lean on this analysis as opposed to your own 'expert' opinion.
The bottom line is that, as JBC emerges from behind the Stemmons sign he is. apparently calm and composed. There are no signs of distress. He is in the same position and posture as he passes behind the Stemmons sign:
The analysis by the Itek Corporation and my own analysis of the Z-film in this thread demonstrate, beyond doubt, it is after this moment JBC suddenly starts to make very extreme and very rapid movements.
THE Z-FILM SHOWS THE MOMENT THIS REACTION BEGINS.
Of course, in your own analysis, in the picture of JBC above, he has been shot over one and a half seconds before this z-frame, leading you to make the hilarious suggestion that Connally didn't notice being shot. And that's the pickle you're in. Because you've put all your eggs in the Phil Willis basket you have a first shot in the mid z190's - this leads to certain, ridiculous notions, which you have to pretend don't exist.
I agree. It is just that, according to the evidence, JFK was reacting to being hit by the first shot and JBC was reacting to hearing it, recognizing it as a rifle shot (and realizing that an assassination was taking place) and turning to check on JFK.
So, you agree with my analysis that the Z-film shows the moment JFK begins his radical, extreme and rapid reactions to being shot, beginning around z225.
And that JBC began his extreme and rapid movements at the same time.
Good for you.
You just think JBC is having this intense physical reaction and screaming "Oh, no, no, no" because he is upset that the day is going to be spoiled and not because he's been shot.
I think you can add that to the list of certain ridiculous things you have to accept.
