LOL. It only "conflicts" with your wacky interpretation of them.
Tina Towner stopped filming about 1 second before Zapruder re-started filming. A second after Zapruder restarted filiming (around z150) the VP car and VP security car are both pointing toward the TSBD with the VP followup car somewhere on Houston approaching the intersection. So if that is where the first shot occurred, these witnesses are wrong:
In the VP car (4th in motorcade):
Hurchel Jacks (driver), WC 18 H 801, said "My car had just straightened up from making the left hand turn" when the first shot rang out.
SA Rufus Youngblood, WC 18 H 767, said that the VP car had turned the corner and he observed grassy area to his right before first shot was heard.
Vice-President Lyndon Johnson WC 5 H 562: said he heard the first shot "after we had proceeded a short way down Elm Street"
Lady Bird Johnson, WC 5 H 565: said "we were rounding a curve and going down a hill" when the first shot was heard.
Senator Ralph Yarborough WC 7 H 440: "as the motorcade went down the slope of Elm Street a rifle shot was heard by me".
Occupants of the VP follow-up car (5th in motorcade) described the moment of the first shot:
Joe Rich. (driver), WC 18 H 800: "I was staying right on his bumper" (of the VP car). "we turned off Houston Street onto Elm Street"
Clifton Carter, WC 7 H 474: "our car had just made the lefthand turn off Houston onto Elm Street and
was right along side of the Texas School Book Depository Building"
SA Kivett, WC 8 H 778: "The motorcade was heading slightly downhill toward an underpass. As the
motorcade was approximately 1/3 of the way to the underpass.."
SA Johns, WC 18 H 764: "at this time were were on a slight downhill curve to the right"
SA Taylor, (18 H 782): "our automobile had just turned a corner"
Occupants of Mayor Cabell’s car (6th in motorcade) recalled hearing the first shot as follows:
Milton Wright (driver), WC18 H 802: "had just turned onto Elm Street and approximately 30 feet from the intersection"
Earle Cabell, WC 7 H 479, said that he was turned around talking to Rep. Roberts and Mrs. Cabell with the TSBD situated to his back.
Mrs. Cabell, WC 7 H 486, "we were making the turn" ... "I was directly facing [the TSBD]"
In addition, there were at least 20 witnesses who said that JFK reacted to the first shot in a distinct manner that is quite inconsistent with smiling and waving for 2-3 seconds. In addition, you have Hughes, Betzner and Willis and several witnesses along Elm who put the President much farther along Elm than he was at z150.
That's not "Croft's statement to Richard Trask". That's from a characterization in an FBI AirTel about Bronson. It may be accurate; it may not be. Croft in 1988 could not confirm the AirTel: "I really don't know how they came up with what they did so fast. They put things together awful quick."
Neither Croft nor the FBI claimed the blank slide "was taken at the moment of the first shot." Trask terms it: "The report further states that Croft said that he believed his last picture was taken simultaneously with the shot that killed the President." There's a case to be made that Croft's talking about the head shot. But that would mean a shot showing Kennedy twice as far away as he was to Willis at Z137, when Willis took his fifth slide.
Trask interviewed Croft and wrote a whole chapter about him. While he also uncovered an FBI document of an interview with Croft and uses a quote from that, it is inconceivable that Trask would not have confirmed with Croft those details when, for example at p.225 Trask, says that Croft quickly wound his camera as the car went by and took his fourth photo as he heard a shot. The bottom line is that Trask confirms that Croft took his z162 photo a perceptible amount of time before any shot was heard.
Dale K. Myers cites this email from Gary Mack dated November 21, 2011. "Tina has always said, and we've been good friends since 1978, the first shot came right after she stopped filming. She has always believed the first shot came within a second or two."
You are assuming that Myers gave a complete quote from Gary Mack's email. It is apparent that he omitted the reference that Mack would have given to the 1996 oral history statement.
So add that to what she said in her book: "...but there was not enough time before the first gunshot sounded—only a second or two, if that, after I stopped filming."
And a 2013 Greensville, Texas newspaper account:
"She said she heard the first shots "about two seconds" after she stopped filming." ( Link )
Not sure how much this influenced her story:
"I’m told it was about two seconds (before) the first gun shot." ( Link )
She doesn't dispute it. Now you work on her at Facebook to say it could have been as much as four seconds.
She merely said: "Now I was beginning to leave when I heard the sky fall in."
Does she describe putting her camera away in its case, or something?
We need to determine why she has given a range of 1 to 6 seconds as the delay between her end of filming and the first shot. Her recollection that she was getting ready to leave when she heard the first shot suggests that the delay was closer to 6 seconds than to 1. Four seconds would put the first shot at about z191.
