I don’t have a story I want to believe apart from what the evidence establishes happened.
BS. You've concocted a story that flies in the face of the evidence and you've spent decades convincing yourself of its plausibility when it isn't remotely plausible. It requires one to accept so many ridiculous premises that only a very silly person would believe it.
The only reason to believe the witnesses is because they could not have been all independently wrong.
Nonsense. Of course they could have all been independently wrong. If dozens of earwitnesses could be wrong about the direction of the shots, they could also be wrong about the timing and the spacing of the shots.
If they had said JFK kept smiling and waving after the first shot, I would have accepted that too. But in that case there would have been very different witness recollections as to where the first shot occurred, the shot pattern as well as a very different zfilm. And we wouldn’t necessarily be talking about it because
Oswald may have botched his next shots as he scrambled to set up the rifle on the boxes as the car moved away.
More silly analysis from a very silly person.
So what is the “forensic evidence” that rebuts the recollections of 25 witnesses that JFK reacted visibly to the first shot (describing actions that are not seen in the zfilm prior to z193)?
The Z=film rebuts those witnesses. It shows both JBC and Rosemary Willis reacting to the missed shot over 3 seconds before JFK in JBC reacted to being hit by the second shot.
