Your explanation ignores the fact the Z-film shows JBC began looking over his right shoulder at Z164
JBC on the other hand told us what he did in reaction to the hearing the first shot and we see him do just that at Z164.
This is a falsehood.
in your delusion you are unaware that we all have access to the Z-film.
The one and only time JBC looks over his right shoulder is after he has been shot @z222/z223.
AT NO POINT BEFORE THIS DOES HE EVEN ATTEMPT TO LOOK OVER HIS RIGHT SHOULDER.
Do yourself a favour and watch the Zapruder film before making any more assinine 'observations'.
This from one of the most deluded contributors on this forum. At Z163 JBC is looking hard to his left.

https://assassinationresearch.com/zfilm/z164.jpgBy Z200, just before he disappears behind the sign, his head is turned hard to the right.
