The Question I would like to ask the panel is:
Is it possible that the Zapruder footage may be digitally altered in the future to show JFK being blown FORWARD and to validate the LHO theory and do you think it is suspicous that the film is now owned by the government?
This question will of course be answered in detail by the panel. However, in the meantime here are a few comments on the Zapruder Film.
There were great suspicions about the Zapruder film from the beginning. Within hours of the assassination Zapruder had sold the 26-second film for $150,000 to Time-Life magazine, which published individual frames but did not allow the film to be screened in its entirety.
The Zapruder film first appeared on national television in March, 1975. The Zapruder film showed Kennedy's violent backward and leftward movement. This convinced many that the fatal head shot come from the Grassy Knoll. Others used the film to argue that it supported the lone-gunman theory put forward by the Warren Commission.
Some writers such as Noel Twyman, David Lifton, Jack White, John Costella and David Mantik have claimed that the Zapruder Film has been tampered with. They have pointed out that the film conflicts with the large number of witnesses who claimed that the limousine stopped after the first shot had been fired. This included the two people standing closest to the limousine, Jean Hill and Mary Moorman, and the four police motorcyclist nearest Kennedy's car.
Detailed analysis of the film has revealed that the limousine displays a variety of irregular movements, including travelling only ten feet within 21 frames between Z-197 and Z-218 (this is only about one half of the expected distance).
Noel Twyman carried out detailed research into the actions of William Greer in the Zapruder film. He discovered that Greer's rapid head turns between Z302 to Z-304 and Z-315 to Z-317 appeared impossibly fast. Experiments were carried out with athletic subjects repeating Greer's actions. These showed that no one was able to reproduce this angular speed. Twyman concluded that frames of the film had been removed therefore speeding up the actions of Greer.
We hope to have two of these experts (Jack White and John Costella) to answer questions on the Zapruder Film. You can see some of their comments at:
I would also suggest the book The Great Zapruder Film Hoax (edited by James H. Fetzer) that was published last year.
