To me it appears that JFK was doing a repetitive almost rhythmic motion in which he was raising and lowering his right arm to wave and turning his head to acknowledge the crowd. And this appears to be interrupted for a little bit immediately following the end of Towner’s film/beginning of Zapruder film. In other words if one watches his actions during the Towner film and can discern the rhythm I just described, one would expect a continuation of that type of rhythm during the first part of the Zapruder film. But that doesn’t happen. It is a considerable amount of time before he starts another wave. And during that interval we can see some quizzical looking expressions on the occupants of the limo as they appear to be looking all around and wondering what that loud noise was. See photo by Croft for the expressions, and the motions in that portion of Zapruder film. By the time of the Garrison fiasco, Phil Willis had changed his claim about the first causing him to take his fifth photo to it causing him to take one of his photos. Willis’ fourth photo was taken (you guessed it) very shortly after z-133. And it is out of focus and motion blurred as one would expect if it had been inadvertently taken before Willis was completely ready and had everything set. JFK appears to be brushing his hair back in Willis 4. Who was it that said the first shot happened right after JFK did that?
I still go with Max Holland when he says the first shot occured about 1.4 seconds before Z133.
If the first shot was the one that injured James Tague, it had to lose its copper jacket somewhere along the way, probably when it glanced off the traffic light mast arm.
Hinkley (sp?) bent over and looked at something on the ground. His attention could have been drawn to the falling debris from that impact.
