Hudson is the man in the center and if shots were fired from directly behind him he's showing very little reaction and in fact the man on the end is turning and running back towards your shots?
Agreed, Marilyn Sitzman is a terrific eyewitness and fully describes the damage as seen in the Zapruder Film, Autopsy photos, X Rays and in the Official Autopsy Report.

If Emmett Joseph Hudson was the "middle man" on the steps, he certainly wasn't sitting down as per his voluntary statement. He mentions a man on his left but fails to mention the man in the red shirt in front of him. It certainly looks like the man in the red shirt is pointing something and when the right hand is fully extended, the man on the left of Hudson decides to dart away. The man in the red shirt also looks like he is doing a "timing/dancing" move to follow the car up and line himself up for a shot. On the original Muchmore Film, it appears that there is a white muzzle flash near the end of his extended arm just at the very instant the President's head disappears behind the motorcycle cop's helmet which corresponds again to Z330/Z331. Timing done by looking at Jacqueline's arm coming around the President's head at Z325 or thereabouts.
I would have to assume that the other 2 standing with Hudson disappeared into the great abyss without so much as an interview. It also appears that the man in the red shirt (below) wears a watch on his left wrist which catches the light when he makes his move. The move this man makes is bizarre and certainly would need explanation from him in my opinion! This move certainly makes the man on the left of Hudson want to get out rather quickly after the red shirted man extends his right arm or it could have been pure coincidental with the scene. On the other hand, Emmet stands there motionless and emotionless - no reaction whatsoever. However, he claims he was sitting on the steps and only mentions the man on the left in his voluntary statement and no mention of the red shirted man - statement therefore appears contradictory to the video entirely or subduing the elimination of the third witness entirely!
There is an instant where we see a similar move as the President's head comes out from behind the sign after the first shot occurred. This person goes from a full arm extension to one of putting that hand behind the back. Again, impossible to see identity of person or see exactly how many where standing there and why that move was exhibited as well as it certainly coincided at a critical time to the passing of the motorcade and the timing of the shots with the POTUS reaction in grabbing his neck with the umbrella man and the Cuban waving at him from the front of the road sign.
