The Nix film was filmed by Orville Nix, just on the opposite side of
A frame from the Nix film may be seen in Robert Groden’s pictorial record of the assassination, (The Killing of a President, p32). There are also Nix film versions available on the internet (Youtube), but none of the ones I’ve seen are the original. How do I discern the original? It is the one featured in stop-motion on the Italian documentary The Two Kennedys which uses a reference circle for an obvious piece of dislodged skull hurtling over the rear of the limo. This is the film that needs to be seen. One can also clearly see a smoke puff rising from behind the fence of the Grassy Knoll - just as described by a number of witnesses standing on the Elm St. Overpass including: Richard Todd, and S.M. Holland (see, the video 'Rush to Judgment' and segments of interviews with Holland, Todd, Lee Bowers and others therein).
Reference has been made to Martin Shackelford commenting that "it seems like a skull fragment flying through the air would be in more than one frame" - but it is clear that what Shackelford was looking at was not the original - intact Nix film, but rather a doctored substitute that emerged after "the original film was lost during the HSCA investigations". As to the most plausible method for doctoring the image, it would have been aerial imaging photography.
Thus, the actual original Nix film was projected frame by frame onto the rear of a glass screen, This corrupted copy was then filmed frame by frame and when the frames nearing the skull fragment were approached, appropriate “touch ups” were performed to eliminate the unwanted whitish blob. It may have appeared then, at most, in one frame – but no more. Since only a few frames would have had to be re-filmed, and the touchups were generally non-descript, no one would have been the wiser. Why go to all this trouble? Because a key evidentiary piece (showing a shot from the grassy knoll) would be obfuscated.
Again, the aim of such film altering is obfuscation and ambiguation so that no clear, incontestable evidence exists. The aim of all the cover-up artists is to keep discussions going endlessly and never have anything resolved - so the Warrenite version always becomes the default.
3. Who was Abraham Zapruder?
While the media scuttlebutt is that Abraham Zapruder was just a little clothing store owner who happened to be at the right place and right time to film the assassination, researcher Russ Baker points out ('Family of Secrets', p. 116):
Based on a computer-enhanced analysis of the next to last frame of the Muchmore film by Jack White at least one assassin was caught in outline on the grassy knoll- aiming his rifle. The flash of a badge discloses he was wearing a police uniform. The interesting aspect here, is that from White’s analysis (see in episode 6 of ‘The Men Who Killed Kennedy’) the shooter was within about 1-2 m of the position assigned using the acoustic testing evidence, and reconfirmed by D.B. Thomas in his (2001) analysis.
Or about 3 in 10,000 odds against the null hypothesis. (The null hypothesis is that which states the echo patterns recorded can be explained by random noised, i.e. the backfires of motorcycle engines). Similar results apply for supposed tampering in the Nix film – since again, a grassy knoll shooter is assumed there as well.
