Dennis David's speech at the Lancer 2001 banquet

Thank you Dennis not only for making this speech but for allowing me to put in on my web site for others to hear. This speech is very inspiring and I urge everyone to listen. Dennis gave some important news regarding the search for the man who killed Lt. Cdr. Pitzer. This news is a followup to the story related by both Dennis and Dan Marvin in part six of "The Men Who Killed Kennedy."

Re-creation film

This is one of the US government's films from the National Archives. It shows a number of things which are not present in the current Zapruder film. One is that the limousine did almost miss the turn onto Elm Street. Another is that the Stemmons Freeway sign was shorter and did not block the view of Kennedy's head except for a split-second at the right edge (as seen in the film).

This film is about 6-1/2 minutes long but only about half contains relevant images or even any images at all. About half consists of either fully-exposed (white) film, unexposed (black) film or extraneous images made while apparently running the camera without actually aiming at a subject, perhaps while watching the footage counter. I only included the portions with images of the limousine.

The Jerry Coley Interview

Mark Oakes and Martin Barkley interviewed Jerry Coley on videotape about a pool of blood that he and a colleague witnessed at the top of the steps on the knoll on November 22, 1963 after the assassination of John F. Kennedy.  Coley gave a detailed account of what he saw, what he did and what happened afterward.  The video runs 55 minutes and it requires RealPlayer.

Martin Barkley's Deep Inside Pegasus Rising

This is a document concerning Martin's theory and speculation about what happened in Dealey Plaza and in Oak Cliff on November 22, 1963.  It relates to what Jerry Coley talks about in the video interview above.

Photos obtained from Martin Barkley which relate to this subject

These photos were found in the 1972 Dallas Police Department yearbook.  Martin would like to find a copy of the 1963 Dallas Police Department yearbook.  Anyone having information about the '63 book can email

Groden and His Magic Rotoscope

This clip shows that frames are missing from the film.

Mack, Moorman and "JFK"

Who owns the copyright to the Moorman photo? I do not believe it is Mack. There is no registration of copyright for that photo or any of the enhancements.

Why did Mack keep it from being used in the movie "JFK" if Mack is really interested in "fixing history"?

What authority did he have to keep Oliver Stone from using it?

Watch this news clip from 1991 and think about the answers to these questions.

Mack Gets Jittery (or, Jerky Is As Jerky Does)

The following was relayed through a third party from Gary Mack.

[quote on]

The old 8 mm prints looked jerky because they were made from poor copies of the Garrison print (from LIFE) and were projected at the wrong speed. Even a 5% increase in speed would make the movements look unnatural. When seeing the film at the correct speed, people are then surprised at the smoothness. MPI did nothing to smooth out the film in the full frame and normal views, only in the closeups where they repositioned certain frames.

[quote off]

The MPI video states quite explicitly, albeit in a misleading manner, that after the individually-copied frames had been scanned and registered precisely with each other (using the perforations and frame edges as reference points), there was a second pass using "finer registration or motion stabilization." When something has been done precisely already, how can it be improved by "finer registration?" The fact is that MPI's video is yet another alteration of the film. A large number of frames were moved in various directions to make the film seem less jerky. The claim was that this was done to remove "camera jitter" but no one involved in the project knew what was camera jitter and what was not in that film. This was an unforgivable further alteration of the film.

Mack's claim that increased projection speed of an inferior copy of the film was the reason it looked jerky is complete nonsense. I have filmed numerous recreations of the Z film myself using a camera of the same model allegedly used by Zapruder and using film comparable (as close as can be obtained) to the film used by Zapruder. I have taken a sample of one film which was made by an amateur photographer using the same camera and film I have used and I have increased the speed by 20%. Even at four times the speed increase that Mack claimed would create jerky motion, the film is still quite smooth. In fact, if I had not stated that the speed had been increased by 20%, I doubt that anyone would realize it. Note that TWO passes of traffic down Elm Street occur in only 18 seconds at this speed. This should be proof enough that the speed has been increased as I have stated.

(Since I first wrote the above, Mack changed his assertion. Below are his further comments.)

[quote on]

Those who really know film know that "overcranking" and "undercranking" are among the oldest of Hollywood tricks. When you change how fast the camera runs in small increments, all sorts of interesting things happen to normal movement. Comedy director Hal Roach was one of the masters at such techniques.

By running the Zfilm 20% fast, one obscures minor frame-to-frame panning errors, so it should look smooth. But a small increase in film speed, which is what often happens with consumer-grade projectors, the jerkiness of the original panning errors is exaggerated. My example of a 5% speed variation is within the area where just such an effect occurs.

[quote off]

Since he made those changes to his earlier assertions, I have created a video to replace the first one which takes into account all of his claims. I took footage of traffic on Elm Street and made a copy 20% faster and a copy 5% faster. I put these into a video along with the original footage at normal speed to show how ridiculous Mack's claims are. There is no more jitter at any speed. The jitter only changes speed according to the speed at which the film is shown.

I went on to demonstrate how excessive jitter can be created by removing frames from the footage. I took the same three video clips and removed two of every three frames (changing the video frame rate from 29.97 fps to 10 fps while keeping the duration of the clips unchanged). This approximates the sort of jitter and extreme shakiness seen in the Z film. Since I removed frames in a set pattern, the shakiness seen in my clips isn't quite the same as seen in the Z film. It is apparent that frames were removed from the Z film in a somewhat random pattern.

(It is possible that your computer may create additional jitter because it cannot play all the frames quickly enough. If this occurs, your computer will lose frames so that it can keep going at the intended speed of the clip. Downloading the video and playing without your browser or other programs running may allow you to play the video without losing frames.)

Radio interviews on privacy issues

There are two interviews here. One took place on 11/18/02 about the privacy concerns around grocery store "savings" cards. This is something which many of you will already know about. They have been used for a long time already.

The other interview took place on 11/20/02 and dealt with new technology which will be coming soon to "tag" all merchandise with a unique radio transmitter/identifier. The plan, as described in the interview, is to place scanners or readers for these ID "tags" in all public places. The "tags" can be read from as much as 30 feet away. Having worked in the electronics industry for over 20 years, I know this is possible. Whether you believe it will ever come into being or not, you should definitely listen to this interview just to have the information.
