Lone-gunman theorists still refuse to come to grips with the hard scientific evidence that the 6.5 mm object was added to the JFK autopsy anterior-posterior (AP) skull x-ray, even though this fact has been confirmed by scores of optical density (OD) measurements, and even though the ARRB forensic radiologist admitted that there is no object on the lateral skull x-rays that corresponds in density and brightness to the 6.5 mm object on the AP skull x-ray.
The 6.5 mm object is the largest and most obvious non-bone object on the AP skull x-ray. A first-year medical student would have no problem quickly identifying it as the largest apparent bullet fragment on the AP x-ray. The object appears to be located on the rear outer table of the skull. The Clark Panel, the Rockefeller Commission’s medical panel, and the HSCA’s medical panel, not having the benefit of OD measurements, logically concluded that the object was a bullet fragment.
The problems with the 6.5 mm object start with the fact that, incredibly, the autopsy doctors did not mention the object in the autopsy report. They did not mention it during their Warren Commission testimony. They said nothing about it in their HSCA testimony. When the ARRB asked them about the object, they said they did not see it during the autopsy. They did not see it during the autopsy because it was added to the AP x-ray after the autopsy.
Since the nose and tail of the supposed single headshot bullet were found in
JFK’s limousine, any fragments on the rear outer table of the skull would have
had to come from the internal cross-section of the bullet. However, Oswald allegedly
used full-metal-jacketed (FMJ) bullets, and FMJ bullets have never been known
to deposit fragments from their cross-section at the entry site when they hit a
skull. Never. This fact led HSCA ballistics expert (and lone-gunman theorist)
Larry Sturdivan to acknowledge that the 6.5 mm object
could not be a bullet
fragment (Sturdivan,
The JFK Myths: A Scientific Investigation of the Kennedy
Assassination, Paragon House, Nook Edition, 2005, pp. 168-170).
Dr. David Mantik and Dr. Michael Chesser have done OD measurements on the 6.5 mm object. These measurements prove that the object is not metallic. The OD measurements and high-magnification analysis of the object reveal that it is a ghosted image that was added to the x-ray via double exposure. Dr. Mantik has even able to duplicate the method that was used to add the object.
The 6.5 mm object was ghosted over the image of a small genuine fragment on the back of the head. The small genuine fragment is on the right side of the object (viewer’s left). There is also a very tiny metallic fleck in the right side of the object (viewer’s left). The OD measurements confirm that the small fragment on the viewer’s left side of the object is metallic.
Most lone-gunman theorists cite Larry Sturdivan's far-fetched explanations for the 6.5 mm object. Sturdivan has offered three explanations: one is that a drop of acid somehow fell on the AP x-ray film and created the 6.5 mm object; one is that a stray metal disk somehow got stuck on the x-ray film cassette; and the third is that a stray metal disk fell the autopsy table and was not noticed when the AP x-ray was taken.
Leaving aside the question of where a drop of acid would have come from in the first place, since when do drops of acid include a well-defined notch that disrupts an otherwise perfectly round shape? The 6.5 mm object has a notch missing on its bottom right side (viewer’s right), but the rest of it is perfectly round. This is one of several problems with the acid-drop theory. The fatal problem with the theory is that if the 6.5 mm object were caused by an acid drop, the x-ray film's emulsion would be visibly altered at this site, but the emulsion is completely intact (Mantik,
JFK Assassination Paradoxes, p. 150).
That leaves the stray-metal-disk theories. First of all, what kind of metal disk would have been present that could have somehow dropped onto the autopsy table or gotten stuck in an x-ray film cassette during a presidential autopsy? Anyway, if a metal disk had been inside the film cassette, it would have produced a dark area at the spot of the 6.5 mm object, not a transparent one.
If a metal disk had been lying next to JFK's head on the autopsy table when the AP x-ray was taken, it would appear on the lateral x-rays as well, but it does not. Of course, it goes without saying that if the radiologist and/or the x-ray technician had noticed a disk lying on the autopsy table after they took the AP x-ray, they would not have taken the lateral x-rays until they retook the AP x-ray.
