Why I am qualified to respond:
I have testified as an expert in crime scene reconstruction and bloodstain pattern analysis in over 30 judicial districts in the states of Louisiana, Mississippi and Florida; including US Federal District Court. I formerly headed the Forensic Investigative Unit for St. Charles Parish of the Louisiana Sheriff's Department and prior to that was second in command at the Lafayette Parish Metro Forensic Unit which served eight parishes. Presently, I am retired yet still do limited consultation for attorneys and law enforcement officials. When I retired I allowed my professional memberships expire. However, I was a member of the International Association for Identification and acquired the Certified Senior Crime Scene Analyst certification. I have served on IAIs subcommittee for bloodstain pattern evidence, and have presented at international and state conferences for that organization. I was a member of the International Association of Bloodstain Pattern Analysts and the Association for Crime Scene Reconstruction.
I am recognized as a Bloodstain Pattern Analysis course instructor by the International Association of Bloodstain Pattern Analysts and the International Association for Identification; and have taught that field of investigation to law enforcement agencies and at police academies for over 20 years. I have published 15 articles in peer reviewed journals, and given lectures at national and international levels. I published my findings concerning the Kennedy Assassination on the web originally in 1995 and have yet for one expert in my field to review my work and find my methods in error.
Based upon my training and experience I feel I am more than qualified as an expert to address the claims made by the web page.
More recently, scientists have discovered that there is something else about the shot to JFK’s head on the forged film that is fake—and can be proved to be fake: the spray of blood that appears at the moment he is shot. Film experts had noted that the “blood spray” in Frame 313 looks like it has been “painted on” and then exposed onto a genuine strip of film. But what tells us that this “blood” is fake is the fact that it disappears into thin air! If it was real, the “blood” should spread out in the frames after Frame 313, and then land on people or objects in the car. But within a couple of frames, it disappears altogether:
The graphs show that the “spray” disappears within three frames, or one-sixth of a second. This can’t happen! Even if you dropped a lead weight from JFK’s temple, it wouldn’t drop into the car this fast! The scientists were also able to show that the “spray” could not have been moving so fast that it shot right out of view before Frame 314.

Even if you dropped a lead weight from JFK’s temple, it wouldn’t drop into the car this fast!
Unfortunately, we are not discussing lead weights. The blood is being forcefully expelled from the wound and is traveling at a higher rate of speed than that of falling velocity. Since 1983 I have been actively involved in the study and recreation of bloodstain pattern created as a result of high velocity impact. This type of analysis is founded in physics and mathematics and based on the study of research performed by many criminalists. Therefore, it satisfies one of the main criteria for evidence analysis specified by the courts - that the evidence has as its basis in sound scientific methodology. Data collection for the analysis was accomplished by shooting through a variety of samples of whole human blood at a series of distances and with a wide diversity of projectile calibers.
Videotape is used to capture the results of the bullets passing through the bloody targets. The blood used in all cases is whole human blood. The videotape used records 30 frames per second. The video utilized approximately 4-5 frames to capture the forceful impact pattern when a low velocity, large caliber projectile with a high KE rate impacted a large volume of blood. This means that partiular pattern was created in its entirety in 1/6 of a second. Faster projectiles resulted in patterns that were created in less than 1/6 of a second. The Zapruder film was recorded at 18 frames per second. If blood is observed in 2-3 frames that would mean the pattern was created and dissipated in a time frame of 1/6 of a second or less. A time frame consistent with patterns created with a high velocity projectile.
Another criteria for evidence analysis specified by the courts is that the analysis used have the ability to be duplicated. This test for the speed of a spatter pattern being created and disipating can be duplicated by placing a video camera at a 90 degree to a bloody target. Fake blood in a sponge secured in a small zip lock bag will work, since all liquids respond in the same manner to forceful impact. You can attach the bag to a pole or other upright item. Hanging a dark surface behind the target will provide better viewing contrast. Use a high velocity projectile to shoot the target. Count the number of frames it takes for the spatter to be created and dissipate.
The scientists were also able to show that the “spray” could not have been moving so fast that it shot right out of view before Frame 314. But even if the blood could have, where would it have ended up?
It would have gone all over the Connallys, and the windows and interior of the limousine. But a frame published only weeks after the assassination, in color, showed no blood at all:
It is amazing that the writer of this article would not consider there were other methods than viewing a single frame of the Zapruder film to determine if blood was present either within or outside the Limo. Especially when there are numerous statements documenting blood being deposited both within and outside the limo. A google search for limo images will result in several photographs of the limo containing blood. One such photograph can be seen here: http://www.jfklancer.../limo/ce353.jpg
Here's one of the limo exterior being cleaned at Parkland Hospital http://jfk.iefactory...os/limohosp.jpg
Additionally, there are many statements of witnesses that indicate blood was found outside the 2 frames in the Zapruder film:
Nellie Connally "I felt something falling all over me. My sensation was of spent buckshot. My eyes saw bloody matter in tiny bits all over the car." Nellie Connally; Nellie Connally: That Day in Dallas by Robert R. Rees.
Mr. KELLERMAN. Senator, between all the matter that was--between all the matter that was blown off from an injured person, this stuff all came over.
Senator COOPER. What was that?
Mr. KELLERMAN. Body matter; flesh..
Mr. SPECTER. When did you first notice the substance which you have described as body matter?
Mr. KELLERMAN. When I got to the hospital, sir, it was all over my coat.
Testimony Of Roy H. Kellerman, Special Agent, Secret Service Beginning At 2H61
Secret Service Agent Samuel Kinney, the driver of the vehicle behind the President. "my windshield and left arm were hit with blood and brain matter immediately after the head shot."
Police Officer Seymore Weitzman in his Warren Commission testimony stated he discovered a piece of skull bone lying in the street, just inches from the South curbing, and roughly 20 feet to Kennedy's left.
Officer William Joseph "B. J." Martin Warren Commission testimony:
Mr. BALL: Did you notice any stains on your helmet?
Mr. MARTIN: Yes, sir; during the process of working traffic there, I noticed that there were blood stains on the windshield, on my motor, and then I pulled off my helmet and I noticed there were blood stains on the left side of my helmet.
Bobby Hargis " ...it was like a bucket of blood was thrown from his head"
Robert A. Frazier testified on 2-21 & 2-22-1969 in the Clay Shaw trial. During his testimony he discussed what was found when the limo was searched at 1am on 11-23. "We found blood and tissue all over the outside areas of the vehicle from the hood ornament, over the complete area of the hood, on the outside of the windshield, also on the inside surface of the windshield, and all over the entire exterior portion of the car, that is, the side rails down both sides of the car, and of course considerable quantities inside the car and on the trunk lid area."
Work that asked to be taken seriously must be researched in depth to assure all facets of the matter in question are considered. When addressing an investigation you can not enter the investigation with a pre-disposed idea and search for supporting evidence. You must uncover and expose all possible information and then form conclusions based upon your findings. The information contained at this page of JFK assassination film hoax is incorrect in its scientific basis. They are guilty of not doing sufficent research on their subject of blood spatter. There are numerous books available at public libraries, and for purchase on the web, that address this subject and support my statements here. Additionally, good research should have indicated a need to determine if witnesses had made statements concerning deposited blood.
I encourage all researchers to thoroughly investigate this subject to help them in determining the validity of the Zapruder film. And I encourage the writers of JFK assassination film hoax: The blood mistake to reconsider the contents of their page because it's their mistake.
