What is this "visual evidence" of a missed shot?
A missed first shot, no less?
They are referred to in the threads that I referenced a few posts ago in this thread. You can find the links to these other threads (Victoria Adams’ view from the fourth floor window” and “Why the first shot missed”) in that post. Off the top of my head, some of them include:
The traffic cop Harkness suddenly turning away from his assigned duty at the intersection of Main and Houston and walking in the direction of the limo on Elm Street with a concerned look on his face (as seen in the Hughes film).
The head turns and looks of concern by the limo occupants (as seen in the Zapruder film).
The sudden head jerk back towards the TSBD and simultaneous beginning of a slow to stop from running by Rosemary Willis (as seen on the Zapruder film).
The sudden jerk upwards and then stop of the operating movie camera being held by Dorman.
The end of Tina Towners film segment of the limo with the first shot happening just after she stopped it (per Tina Towner).
The out of focus photo by Phil Willis (#4). I believe that the reason it is out of focus is that the first shot caused him to inadvertently press the shutter button before he was completely ready to shoot. His later testimony at the Clay Shaw trial states that one of his photos was taken as a result of the first shot. I believe that by then he realized that his fifth photo wasn’t in sync with any shots. And the forth photo is the only one of his photos that is that much out of focus.
Other evidence (that we need to use a 3-D computer model or map of Dealey Plaza to obtain the visual aspects) includes Howard Brennan’s account in his 11/22/63 affidavit regarding JFK lining up with the last windows of the TSBD from Brennan’s position when the first shot rang out. And Victoria Adams’ account of the limo going behind the tree from her position as the first shot sounded.
All of the above items occurred right around the time of Z133. I believe that the sound of the first shot is the reason.
