One does not have to rely on anything Rosemary said to use her sudden turn at z204-207 (which is the only time she is looking back at the TSBD) together with other evidence to see that the turn is in response to the first shot.
That other evidence includes her father's statement that his z202 photo was taken an instant after the first shot,
"Slide No. 4" "When I took slide No. 4, the President was smiling and waving and looking straight ahead, and Mrs. Kennedy was likewise smiling and facing more to my side of the street ... | | "Slide No. 5" "... When the first shot was fired, her head seemed to just snap in that that direction, and he more or less faced the other side of the street and leaned forward"
|
“Well, after having photographed the President on Main Street
and on Houston Street and then in front of the Depository
Building on Elm Street I cocked my camera for another picture
and this loud shot went off and the first reaction was that could
it be a crank or a firecracker but it was so loud and of such a
sound it had to be rifle so I became alarmed. I was trying to take
a picture at the moment and the reflex from the shot caused me
to take one of these pictures.”
Above is what Phil Willis said at the Clay Shaw Trial, again hinting that the shot occurred just after taking Photo No. 4: "I cocked my camera for another picture and this loud shot went off". If Willis took the Photo as a "reflex" (ie: no time to think), why does he say that he had time to think after whether the shot was "a crank or a firecracker" and that this was why he "became alarmed"?
together with Jack Ready's statement that he turned immediately after hearing the first shot (he begins turning at z199).
We both agree that the witnesses along Elm St. and those in the motorcade who relate their position at the time of the first shot, as well as Betzner and Croft, provide abundant evidence that the first shot was later than 186 and struck JFK. We just disagree that there is evidence that he was hit as late as z222/223.
Jerry likes to explain away the evidence he does not like. As far as the Secret Service agents reacting, one can see Jack Ready remove his right hand from the front handhold at z199 and begin his turn around that is complete by z256 as seen in the Altgens photo. He said he turned immediately in response to the first shot.
Agent John Ready stands camera-left and at front on the followup car's running board (He's just below the top sprocket hole and vertically above the characters "Z1") | | In about one second Ready has made a rapid rightward head turn |
"I heard what appeared to be fire crackers going off from my position.
I immediately turned to my right rear trying to locate the source but
was not able to determine the exact location." -- John Ready
Other rightward head turns in that same interval are the Connallys and Mrs. Kennedy. (Frames chosen for their clarity).
Andrew apparently agrees with me that not all the agents who claimed they reacted immediately on hearing the first shot did so, as least through actions visible on the Zapruder film.
