I guess I should have introduced myself properly, explained my level of knowledge and where I stand as far as what I believe happened.
1. I believe Oswald shot Kennedy and was the only active shooter
2. I don't believe Oswald was recruited or paid by any organization to do the deed
3. I think Oswald may have received encouragement to do the deed while in Mexico
4. This encouragement may have been coordinated or just happenstance
5. I think there may have been foreknowledge of the assassination by people connected to the CIA
I find the language used in JFK assassination discussions deplorable. Kooks, idiots, morons. We traditionally would have researchers discussing different possibilities, not this sort of football match. Maybe it's a symptom of the internet. But I don't want anything to do with this brand of discourse and that's why I won't be engaging Hank any more.
Imhotep, you might want to rethink your belief in the single-shooter theory. A kind of "rosetta stone" for understanding that there is something seriously wrong with the official shooting scenario is the EOP wound.
The autopsy report, the three lead autopsy doctors (Drs. Humes, Boswell, and Finck), five additional autopsy witnesses (John Stringer, Roy Kellerman, Francis X. O'Neil, Richard Lipsey, Charles Boyers), and the face sheet diagram marked by Boswell and signed by Kennedy's personal physician George Burkley all indicate that Kennedy had an entry wound near his external occipital protuberance, in the autopsy report's words "2.5 centimeters to the right and slightly above the external occipital protuberance". Cyril Wecht also identified a possible bullet fragment in the upper neck on one of the X-rays, near the EOP.
The surviving autopsy photographs and X-rays are ambiguous as to showing this wound, and later the Clark Panel and the HSCA's panel of forensic experts theorized that the entry wound was actually four or more inches above where the autopsy doctors placed it, in the parietal bone instead of the occipital bone.
The HSCA theorized that the confusing close-up photographs of Kennedy's empty skull showed both this parietal entry wound and a frontal exit wound. The problem with that? That only leaves a five-inch wide skull cavity to remove the entire brain from the cranium. This interpretation of the open-cranium photographs cannot be true unless previously-separated portions of skull bone were pieced back together for the taking of those pictures, contrary to all statements of the autopsy participants.
The same problem applies to the repeated, consistent statements of autopsy doctor and forensic pathologist Dr. Finck, who arrived at the autopsy after the brain had already been removed, and always said that he examined the beveled entry hole within the intact, empty cranium. Again, this would be after the large head wound had been further enlarged to facilitate removal of the brain. With the original lower placement of the entry wound, it makes sense that there would be enough space on the top of the head to fit the entire brain through and still keep the beveled entry hole intact. But the revised placement of the entry wound, in the "cowlick" area, cannot be compatible with this important observation of Dr. Finck. To make a large enough skull cavity to remove the brain, the "cowlick" area of the skull would have had to be among the portions of skull bone separated. A typical brain removal procedure requires the entire top of the skull to be removed.
Also consider that the repeated, consistent statements of Dr. Humes and Dr. Boswell indicate that the area of the skull around the large head wound was so badly fractured that portions of the skull would just separate in their hands upon examination. They said that virtually no sawing of the skull was necessary to create a large enough skull cavity to remove the brain.
What's wrong with having 'the' entry wound on the base of the head instead of the top of the head? 1. The trajectory between the original EOP wound location and the top-right side of the head, at Zapruder frame 312-313, would require a sharp upwards deflection of the bullet, 2. The pattern of fragments on the head X-rays are entirely on the top of the head, besides the one possible minute fragment in the upper neck. A trajectory from the original EOP location to the top of the head would probably leave bullet fragments in the occipital-cerebellar are, 3. A trajectory from the original EOP location to the top-right side of the head would severely damage the cerebellum. The official brain photographs show only a slightly disrupted cerebellum.
One can see why the upper "cowlick" entry wound is now basically considered canon to the official story.
Can a missile entry in the original EOP location be compatible with the official evidence, without anything being faked? Unless you want to invoke obscure high-tech ammunition that can not show up on X-rays, the closest likely option would be that the missile that entered the EOP subsequently exited the throat, creating the throat wound. This impedes on the single-bullet theory. Otherwise you would probably have to invoke X-ray or film alteration, or some kind of bizarre body alteration. For the EOP entry wound to be compatible with the official evidence, the large head wound would have to be created by a separate missile. More than one gunshot to the head.
