Counting Pixels in the Zapruder film.

The Bronson photo here:



Is said to have been taken at around z225 or z226. You can see at this time the boy Joe Brehm is well to the side of his father (at least from this angle). This is 53 frames (allegedly ~2.9 seconds before frame 277). The boy Joe Brehm has moved behind his father and then back out from behind him in 3.9 seconds or less without visibly moving his feet.

DCM clearly in the street, fist raised, UM with umbrella high in the air.
