I already answered all of your and Organ's arguments. You are simply ignoring what the photographic evidence shows. Organ has discredited himself innumerable times in this forum and has proved he is simply not to be taken seriously.
I might add that Milicent Cranor, one of the most careful, studious researchers around, likewise argues that the Zapruder and Nix frames proves the Zapruder film has been altered.

You're joking, right? Your understanding of perspective is childlike and the following graphic absolutely demolishes your Hill and Jackie on the trunk garbage.

The following graphic is from the grossly misinformed mind of Michael T. Griffith.

You are simply ignoring what the photographic evidence shows.
By using techniques you simply can't comprehend like computer 3D modelling and advanced film stabilization, all your worthless observations like your insane Brehm's son theory and as shown above by your Jackie and Hill on the Trunk conjecture have been thoroughly destroyed.

Wow, "careful and studious" that's some powerful credentials she's got there, too bad they are totally inadequate for this discussion. Much like yourself she has no understanding of perspective and her claim that film frames were removed to achieve the Hill and Jackie positions are another embarrassment, as explained to you on numerous occasions, even one removed frame from a panning shot would be immediately obvious and to laughably suggest multiple removed frames, shows a complete lack of understanding of basic cinematography 101.
