Your "logic" escapes me. You are saying that his hand must emerge from beneath the top of the door before it can be moving from right to left! Yet we see it moving from right to left in z224-231. Why does the motion have to be seen by Zapruder in order for it to occur? Why can it not be moving when we cannot see it? Simple question....
Nobody, at any point has disputed whether JBC's hand is moving left to right.
It hasn't been brought up at any time.
You've introduced it, as you often do, to argue a point that never existed.
"You are saying that his hand must emerge from beneath the top of the door before it can be moving from right to left!"That's an untruth (I know I've got to be careful using the word 'lie' with you).
Nowhere have I said anything even remotely like that.
"Why does the motion have to be seen by Zapruder in order for it to occur?"Do you have any idea how crazy you're coming across? In the post you are responding to I've said his hand was in constant motion. Can't you remember? It was the post you were responding to.
"Why can it not be moving when we cannot see it?"WTF are you talking about? Even for you this off the charts.
It has been your contention that the 'lapel flip' is caused by JBC's hand moving across the front of his jacket.
We can see the front of his jacket in the Z-Film.
We can see that the lapel flip occurs while his hand is still down below the top of the door frame.
When his hand comes into view and moves across the front of his jacket the lapel flip has already occurred.
WHAT DO YOU NOT UNDERSTAND?
HONESTLY, WHAT IS IT YOU ARE STRUGGLING WITH?
