A major problem with self-professed "JFK assassination researchers" is their lack of proper citations and methodology. For example, Jack White has recently again cited a 9-year-old paper by a "school principal" that backs ups Jack's claim of Zapruder film "alteration."
What Jack doesn't do for us is to properly cite just exactly what the school principal was studying. I mean, nine years ago there were several copies of the Zapruder floating around - from the worthless-for-research contrasty, grainy copies bootlegged from the Clay Shaw-trial-era copy, to those with amateurish edits (like the Medio / MacMillan CD-ROM rendition). Heck, I have a copy of the Zapruder film that I can convince a crowd that shows Secret Service Agent Greer pointing a nickel-plated revolver at the President! (One of Jack White's friends, Roy Schaeffer, firmly believes that Greer shot at the President from the limo driver's position.)
A responsible researcher would take this nine-year-old study and return to the author - with the best available copy of the Zapruder film available. And ask the researcher if all these "anomalies" appear in a piece of evidence whose heritage CAN be defined.
But we will not see Jack White taking this responsible step. He wants us to believe that there are scores of ("30 seconds are missing!") "excised frames," "motionless people," "super-human movements," "stick people," "disappearing loads in the backs of pickups," "false shadows," "enlargement of only the background of the film by 130 percent," et al ad nauseum.
Jack has used this "motionless people" claim several times over the years. But when confronted with evidence of very obvious motions (13 distinct motions) by another researcher five years ago, he backed down and admitted that they weren't really motionless. "Almost motionless," was the phrase Jack started to use. Then Jack started to tell people that MOTION WAS ADDED BACK IN to the Zapruder film in Frames 133 to about 196. Now he appears in this forum to start the silliness all over again.
One would think that these "master alterationists" would have the President's head movement at the time of the final head shot(s) to move violently towards the front to bolster the single assassin theory. I mean, if they can re-position spectators...enter false shadows...repeat a line of spectators frame after frame without altering the background...alter the foreground only for several frames...(ALL things Jack White belies was done to the film) - then certainly they could have performed more editing to actually indicate bullet trajectory.
Another item of note: None of those who claim that the Zapruder film was masterfully altered give any reasonable amount of time for the task to be accomplished...The chain of possession of the original and copies made in Dallas has been responsibly established. But don't ask those who have staked their reputations and made money off their "alterationist" nonsense to actually cite the time it would have taken to so masterfully have altered this footage and WHEN in the chain of possession it occurred.
