Take a look at the Muchmore film ( similar perspective as Nix film) and explain why the men on the GK steps are not reacting even after supposedly 2 loud shots have been fired and they were close enough to see JFK and JBC reactions at Z224.
The Newmans ( with small child) who eventually laid on the ground) haven’t yet reacted. As close as they were , if 2 loud shots have been fired and the 1st one maybe was 3 seconds prior and the 2nd shot has hit JFK and he’s obviously slumping, seems like they would be diving to the ground earlier than waiting 4.8 secs longer until the Z313 shot.
Also of note is that DC man still had his hand raised and doesn’t drop it upon hearing the supposed 2nd shot at Z224 or seeing JFK hands going up to his throat and then slumping over.
There’s also a man near Altgens who does not dive to the ground until after the Z313 shot.
Oddly Altgens himself doesn’t seem quite aware either even after the Z313 shot, but then he may have become aware at Z313 but chose to continue standing where he was bravely determined to try to take another photo.
Charles Brehm, should have surely been aware 2 rifle shots have been fired and seeing JFK react at Z224 but he doesn’t seem to be aware.
The SS agents are not looking back at TSBD up till Z 207 and it’s not until about Z255 that SS agent Clint Hill finally seems aware and the other agents have turned their heads back towards the TSBD.
There just is not enough reaction by ANYONE in the groups of people in close vicinity to the JFK limo that really substantiate that a shot was fired prior to Z 224.
Except for the Z170 turn of Jackie’s head and JFKs head being turned sharply towards the right side of the limo, which if that was a loud rifle shot causing that, then why the other people are not apparently reacting in some way?
That Z170-Z207 section of the Z film kind of refutes Andrew Masons theory of a Z195- thru JFK neck shot, because JFKs head was turned so far to the right, that if a shot went thru the neck, then it likely would not have exited the center of trachea but rather to left of center.
Lack of reaction by observers nearby the JFK limo, continues between the gap from Z224-Z313. This indicates that not only was there probably no loud shot prior to Z224, but that there was probably no 2nd shot that was spaced evenly between Z224 and Z313.
Even the JFK limo driver Greer, is not apparently cognizant that that JFK and JBC have been hit, because slowing down is an act of uncertainty rather than immediate recognition that 2 loud rifle shots have been fired.
