You suggested that the Croft photo shows "concern". Was there another one that showed a similar expression?
Not that I am aware of.
As I said, it is not a good idea to base a conclusion based on a single photo: i.e. concluding that she looked concerned because of her expression in Croft's photo.
OK. But that does not mean they didn't hear it and a few seconds later, after seeing the effects, didn't recognize that it had been a rifle shot.
The first shot missed. Therefore the effects were not apparent.
My point was that just because they may have initially attributed the first bang to a firecracker, ensuing events would have persuaded them that it wasn't. It is difficult to believe, without evidence, that anyone who initially thought it was a firecracker would have continued to believe - after the three shots - that the first loud bang was a firecracker (or, as Jerry insists, would have forgotten about the first loud noise completely).
Gov. Connally said he immediately recognized the sound as a rifle shot and feared an assassination was unfolding. I don't seen anything prior to about z228 that indicates that kind of a reaction.
He snapped his head to the right then to his left (where Croft captured his concerned expression). Then back to his right. His actions and expressions are consistent with recognition of the rifle shot. The only thing he didn’t do was scream for everyone to duck. Instead he said something like oh no, they are going to kill us all. That dialogue only appears to have distracted Jackie for a few seconds.
He turned his head to the right at the same time that Jackie and JFK turned their head to the right. He never turns around to look at the President, which is what he said he did in response to the first shot, until after z230.
If you want to reach an accurate conclusion, you should look at all the evidence.
I have been looking at the other evidence. The visual evidence is what I am focused on now.
And my point is that if you want to draw conclusions from evidence it must fit with
all the evidence. If what you think you see in the zfilm does not fit with the rest of the evidence you should try another interpretation that does.
