Yes, I've read John Corbett's latest reply. It is so loaded with evasion, distortion, deception, and error that it's not worth answering. If anyone has any questions about any of his statements, feel free to message me or post them here. Anyway, moving on. . . .

For those who might be interested, another worthwhile discussion on some of the major problems with the autopsy evidence is presented in chapter 8 of Dr. Don Thomas's 2010 book Hear No Evil: Politics, Science, & the Forensic Evidence in the Kennedy Assassination. Dr. Thomas is a retired USDA research scientist. He's had over 100 articles on biology, entomology, DNA, phylogeography, and ionizing radiation published in peer-reviewed scientific journals.

He discusses the impossibility of an FMJ bullet "shearing off" a sizable fragment (or any fragment) at its entry point on a skull, the photographic and x-ray evidence of a frontal shot, the conflict between the head photos and the skull x-rays regarding missing frontal bone, and other important issues relating to the autopsy evidence.

MTG: Dr. Thomas is a retired USDA research scientist.

He's an entomologist, an expert on insects. That doesn't make him an expert on gunshot wounds or on proper autopsy procedure.

This is nothing more than an attempt at Appeal to Authority, except the "authority" isn't actually an authority.

I've been trying to explain this to MTG for weeks. So far, it hasn't taken. Maybe you will have better luck than I have.

I've already answered this argument. But, you guys just repeat the same arguments over and over and ignore counterarguments.

The point is that Dr. Thomas is a scientist, someone trained in scientific methodology and analysis. He's applied those skills to the JFK case, and he's done so very expertly. For example, research done by BBN scientists from 2015 to 2018 proved that Dr. Thomas was right and that acoustical-evidence critic Dr. Ralph Linsker was wrong about the make-or-break issue of PCC testing of the Decker "Hold everything" transmission and the Fisher "I'll check it" transmission.

On the behavior of FMJ bullets, Dr. Thomas cites Dr. Vincent DiMaio. As I know you know, because I proved it to you, Dr. DiMaio said that FMJ bullets will never, ever, ever shatter into dozens of pieces after penetrating bone, that if they leave any fragments they will be few in number, and that x-rays that show numerous tiny fragments rule out FMJ ammo. In fact, just to refresh your memory, let's read again what Dr. DiMaio said on this key issue:

An x-ray of an individual shot with a full metal-jacketed rifle bullet . . . usually fails to reveal any bullet fragments at all even if the bullet has perforated bone such as the skull or spine.If any fragments are seen, they are very sparse in number. . . .(Gunshot Wounds, p. 166)

In x-rays of through-and-through gunshot wounds, the presence of small fragments of metal along the wound track virtually rules out full metal-jacketed ammunition.. . . In rare instances involving full metal-jacketed centerfire rifle bullets, a few small, dust-like fragments of lead may be seen on x-ray if the bullet perforates bone. One of the most characteristic x-rays and one that will indicate the type of weapon and ammunition used is that seen from centerfire rifles firing hunting ammunition. In such a case, one will see a 'lead snowstorm'. . . . Such a picture rules out full metal-jacketed rifle ammunition or a shotgun slug. (Gunshot Wounds, p. 318)

Did you catch that? (1) In the "rare" cases when FMJ bullets do fragment if they penetrate bone, they will only leave "a few" fragments. (2) If an x-ray shows a "lead snowstorm," this "rules out" FMJ ammo.

This is nothing more than an attempt at Appeal to Authority, except the "authority" isn't actually an authority.

Right, never mind that he cites experts in the relevant fields. You'd know that if you'd read his book.

Morever, as I've pointed out before, for decades WC defenders have been citing Dr. John Lattimer and Dr. Robert Artwohl on the forensic and wound ballistics evidence, even though Lattimer was a urologist and Artwohl was a general surgeon. You guys have cited a drummer named Steve Barber and former Dallas sheriff Jim Bowles to attack the HSCA's acoustical evidence. You guys have cited the Haags, who are downright quacks and cranks, to support the SBT.

Yet, trolls like John Corbett summarily dismiss medical evidence of multiple gunmen identified by neuroscientists, ballistics experts, physicists, radiation oncologists, neurologists, firearms experts, medical scientists, research scientists, radiologists, etc., because they're not forensic pathologists.

You're always admonishing me for disregarding eye witness accounts.

Umm, no, I've admonished you for being severely biased in your selection of which eyewitness accounts you accept and which ones you reject.

Anyone who studies the assassination will quickly see that the eyewitness accounts overwhelmingly support the conspiracy view and contradict the lone-gunman view.

Here's what the HSCA's own report said about Officer McLain:

"Subsequent to his hearing testimony, McLain stated that he believed he turned on his siren as soon as he heard Curry's order to proceed to Parkland Hospital . He said that everyone near him had their sirens on immediately.(91) Should his memory be reliable, the broadcast of the shots during the assassination would not have been over his radio, because the sound of sirens on the tape does not come until approximately 2 minutes later. The committee believed that McLain was in error on the point of his use of his siren."

This is further proof that you have no business discussing the acoustical evidence. I asked you how the dictabelt could have recorded gunfire N-waves, muzzle blasts, and muzzle-blast echoes, in the correct order and interval, if it was not recorded in Dealey Plaza during the assassination. I asked you how the dictabelt could contain numerous striking timing-movement correlations with the recording of the test-firing in Dealey Plaza, if it was not recorded in Dealey Plaza during the assassination. I asked you how the dictabelt could have recorded windshield distortions only when the microphone was in position to record them and never when it was not in position to record them, if the dictabelt was not recorded in Dealey Plaza during the assassination.

And your answer to all this evidence is to cite McClain's belated story that he turned on his siren as soon as he heard Curry's order! To put it another way, you're citing a belated claim by a patrolman who changed his story when he was no longer under oath and are pretending that this somehow explains the hard scientific evidence on the dictabelt itself.

BTW, why do you suppose the NAS panel made no effort to explain the N-waves, the muzzle blasts, the muzzle-blast echoes, the interval and order of those sounds, and the windshield-distortion correlations? Humm? That's right: they didn't say a word about any of those remarkable evidences.

And I'm still waiting for you to explain the fact that the NAS panel admitted (1) that there was a 93% probability that the timing-movement correlations identified by the BBN scientists occurred because the dictabelt recorded sounds in Dealey Plaza during the assassination, and (2) that there was a 77.7% probability that the 144.9 impulse pattern is gunfire from the grassy knoll. 

Furthermore, I notice (1) that you snipped the paragraph that comes right before the one you partially quoted about McClain's claim regarding his siren, and (2) that you did not even quote the entire paragraph about McClain's belated claim, and (3) that you snipped the paragraph that follows the one you partially quoted. Humm, why did you do that? Or did you just copy and paste the statement from some lone-gunman site and not realize it was only a partial quote and was being taken out of context? Let's read what the paragraph before the one you quoted says:

Officer McLain's acknowledged actions subsequent to the assassination might explain the sound of sirens on the tape. McLain was in fact probably on Stemmons Freeway at the time Henslee noted that an unknown motorcycle appeared to have its microphone switch stuck open. McLain himself testified that following the assassination, he sped up to catch the front cars of the motorcade that had entered Stemmons Freeway en route to Parkland Hospital. In any event, it is certain he left the plaza shortly after the assassination. The cars in the motorcade had their sirens on, and this could account for the sound of the sirens increasing as McLain drew closer to them, whether he left Dealey Plaza immediately or shortly after the assassination. . . . (HSCA report, pp. 78-79)

Now let's read the rest of your quoted paragraph and the paragraph that follows it, starting with the last sentence you quoted:

The committee believed that McLain was in error on the point of his use of his siren. Since those riding in the motorcade near Chief Curry had their sirens on, there may have been no particular need for McLain to turn his on, too. The acoustical analysis pinpointing the location of the microphone, the confirmation of the location of the motorcycle by photographs, his own testimony as to his location, and his slowing his motorcycle as it rounded the corner of Houston and Elm (as had been previously indicated by the acoustical analysis),(92) and the likelihood that McLain did not leave the plaza immediately, but lagged behind momentarily after the assassination, led the committee to conclude it was Officer McLain whose radio microphone switch was stuck open.

Further, the committee noted, it would have been highly improbable for a motorcycle on Stemmons Freeway to have received the echo patterns for the four impulses that appear on the dispatch tape. As noted in more detail below, to contend that the microphone was elsewhere carries with it the burden of explaining all that appears on the tape. . . . Similarly, those who contend it was not in Dealey Plaza must explain the sounds that indicate it was. As Aschkenasy testified, the echo patterns on the tape would only have been received by a microphone located in a physical environment with the same acoustical characteristics as Dealey Plaza.(93) It is extremely unlikely that the echo patterns on the tape, if received from elsewhere, would so closely parallel the echo patterns characteristic of Dealey Plaza. (HSCA report, p. 78)


You keep repeating the misleading, dishonest argument that Dr. Barger said there was only a 50% probability that the dictabelt contained assassination gunfire impulses, ignoring the fact that he specified this was a preliminary finding and that he said this (1) before the Queens College acoustical experts reviewed BBN's initial findings, (2) before the Dealey Plaza test firing was conducted, and (3) before the BBN and Queens College acoustical scientists were able to compare the dictabelt impulses with the test-firing impulses.

I guess Dolce didn't give the WC a medical reason the SBT was impossible either.

You guessed wrong. As I noted in my reply, he pointed out that the SBT wound-ballistics test, which he supervised, proved the SBT was impossible. How did you miss this?

I guess I have this goofy idea that forensic medical examiners are the most qualified people to assess the evidence from a medico-legal autopsy.

Do you really think people can't see through this dodge? You keep ignoring my counterarguments to this evasion. You keep dodging the fact that even many forensic pathologists who don't posit multiple gunmen have produced findings that destroy your version of the shooting, e.g., the FPP's documentation of the fact that the autopsy brain photos, if authentic, categorically rule out the EOP site; the fact that the back-wound bullet entered and tunneled at an upward angle, a datum that the FPP lamely tried to "explain" by assuming JFK was leaning well over 50 degrees forward when the bullet struck; and the fact that the only fragment trail on the extant skull x-rays is the high fragment trail, which bears no resemblance to the low fragment trail described in the autopsy report.

When I mentioned several forensic pathologists who've said the SBT is false and/or that FMJ ammo could not have caused the bullet fragmentation seen in the autopsy skull x-rays, you dodged these facts with the phony argument that I didn't quote their explanations for their findings. Well, no, I'm not going to copy and paste several pages of their research for you, when you can read it yourself. The fact that you refuse to read their research says much about your bias and lack of credibility. 

When I pointed out that radiology and forensic experts consulted by the HSCA noted the skull x-rays show a large amount of missing frontal bone, you erroneously claimed that the missing frontal bone was only at the rear of the bone. You clearly still have not read John Hunt's detailed article "A Demonstrable Impossibility: The HSCA Forensic Pathology Panel’s Misrepresentation of the Kennedy Assassination Medical Evidence," which I've cited to you several times.

Also, Dr. Doug Ubelaker, one of the ARRB's forensic experts, noted that the amount of missing frontal bone in the AP skull x-ray is inconsistent with the appearance of the forehead in the autopsy photos, as I've mentioned to you before. When I raised this point and his observation that the autopsy photos indicate the bullet traveled from front to back, you lamely dismissed his findings because he was "only" a forensic anthropologist.

That won't work because when the FPP wanted help with reconstructing the skull wounds with the skull fragments, they asked a forensic anthropologist, Dr. Lawrence Angel, for assistance, and Dr. Angel's diagrams show the missing frontal bone extending more than halfway into the frontal bone from the rear edge of the bone and clearly near where the hairline was. This is another serious problem with the autopsy photos of the head.

You on the other hand think a radiation oncologist is well suited for that job.

Dr. Mantik was eminently qualified to perform OD measurements on the autopsy skull x-rays at the National Archives, and he found hard scientific evidence that they've been altered--he was even able to duplicate how the alteration was done. And, Dr. Chesser, a neurologist who examined the autopsy materials at the National Archives and who also examined JFK's pre-mortem skull x-rays at the Kennedy Library in Boston, did his own OD measurements and confirmed Dr. Mantik's finding.

As I've pointed out to you several times now, a forensic pathologist will usually not be an expert in ballistics, radiology, and physics, much less OD measurement and analysis. Yet, you keep repeating your flimsy dodge that we should ignore all forensic-related findings made by ballistics experts, physicists, neurologists, neuroscientists, radiation oncologists, radiologists, etc., because they're not forensic pathologists.

I see you're still repeating the falsehood that radiation oncologists are not trained in reading x-rays. Here's what Dr. Greg Henkelmann, himself a radiation oncologist, has said about Dr. Mantik's OD research on the skull x-rays:

Unlike other evidence, optical density data are as “theory free” as possible, as this data deals only with physical measurements. To reject alteration of the JFK skull X-rays is to reject basic physics and radiology. Dr. Mantik has a PhD in physics and has practiced radiation oncology for nearly 40 years; he is thus eminently qualified in both physics and radiology. (Front matter in Dr. Mantik's book JFK Assassination Paradoxes)

If you Google the question "How much training do radiation oncologists get in radiology?", here's the answer you will get (note: nuclear medicine is a specialized area of radiology):

Radiation oncologists typically complete a 1-month formal rotation in diagnostic imaging or nuclear medicine during their 4-year radiation oncology residency. While this is the minimum formal requirement, they receive heavy, daily exposure to oncologic imaging throughout their training to master CT, MRI, and PET scans for precise tumor targeting.

Because radiation oncologists must accurately identify tumors, organs, and surrounding healthy tissues to plan radiation fields, their training integrates radiology concepts in several ways.


In short, most radiation oncologists are not full-fledged radiologists, but they receive considerable training in radiology. If a radiation oncologist becomes interested in a gunshot case, especially if he does some reading in forensic science (as Dr. Mantik has done), he can apply his expertise to reading the x-rays of the gunshot victim, and, crucially, he can do OD measurements of the alleged/identified bullet fragments in the x-rays to determine if they're actually metallic fragments and to determine their density/thickness, which is something that few forensic pathologists can do. 

And, again, while he was working as a radiation oncologist, i.e., before he retired, Dr. Mantik was licensed in radiology.

The point is that Dr. Thomas is a scientist, someone trained in scientific methodology and analysis. He's applied those skills to the JFK case, and he's done so very expertly. For example, research done by BBN scientists from 2015 to 2018 proved that Dr. Thomas was right and that acoustical-evidence critic Dr. Ralph Linsker was wrong about the make-or-break issue of PCC testing of the Decker "Hold everything" transmission and the Fisher "I'll check it" transmission.

The late Dr. Thomas was way more serious-looking than me, I'll give him that: https://unsm-ento.unl.edu/workers/DThomas.htm. On top of which, his investigative responsibilities involved "host associations of cattle fever ticks in the permanent quarantine zone along the Texas-Mexico border." I will admit, what I know about cattle fever ticks could be comfortably written on a cattle fever tick if you could get the silly beast to sit still. He "also developed expertise in the taxonomy of stink bugs (Pentatomidae), the bionomics of livestock insects, and the ecology of desert tenebrionids." If this were not enough, "An avocational interest in the Scarabaeidae resulted in avid collecting and becoming an aficionado of scarab beetle diversity." We do have that in common - I'm kind of a scarab beetle sort myself.

"The point is that [Dr. Payette] is a [lawyer], someone trained in [the evaluation of evidence] and analy[tical thinking]." See how that works? Everyone is an expert. (Because a JD degree is a "Juris Doctor," some lawyers actually do refer to themselves as Dr., which other lawyers find highly comical. Some, like Kevin Hofeling, who is no longer even a lawyer, insist on using "Esq." as though they were 18th Century barristers.)

You really don't seem to care where a person's area of expertise lies. As long as he has expertise in some field and he tells a story that fits your narrative, that's good enough for you.

Explain why a shattered FMJ bullet ended up in the limo and was found that night by the Secret Service.

It is very rare for military FMJ bullets to be used in a homicide, and specifically involved in gunshot wounds to the head. The overwhelming number of gunshot homicides are committed with handguns at close range. More people are killed with bare hands and feet each year than with rifles. Only several hundred homicides are committed each year with all rifles and those using FMJ ammo are a subset of that. Those involving gunshots to the head with military FMJ ammo would be an even smaller subset. Given those figures, one has to question how many homicides Di Maio has examined in which the victim was killed by a FMJ bullet to the head fired from a rifle. It would not surprise me if the answer is zero.

You seem to favor quantity over quality in your posts. Rather than spend another hour of my time with a point-by-point refutation of your typical long winded post, I will simply point out the booger you have to deal with. There is photographic evidence that Officer McLain's motorcycle was not in the position the acoustics team determined he needed to be for their findings to be valid. There is not a scrap of forensic, medical, or photographic evidence that supports a shot from the GK, nor did any eyewitness on either side of the fence see a shooter even though there were people on both sides of the fence in position to see such a shooter and more who raced to the area following the shots who saw a gunman. Makes it kind of hard to believe the acoustical evidence that a gunman fired from the GK.

You guessed wrong. As I noted in my reply, he pointed out that the SBT wound-ballistics test, which he supervised, proved the SBT was impossible. How did you miss this?

You keep claiming these people have proven the SBT is impossible without ever telling us why they said it is impossible. That makes it kind of hard to evaluate their conclusions.

Do you really think people can't see through this dodge? You keep ignoring my counterarguments to this evasion. You keep dodging the fact that even many forensic pathologists who don't posit multiple gunmen have produced findings that destroy your version of the shooting, e.g., the FPP's documentation of the fact that the autopsy brain photos, if authentic, categorically rule out the EOP site; the fact that the back-wound bullet entered and tunneled at an upward angle, a datum that the FPP lamely tried to "explain" by assuming JFK was leaning well over 50 degrees forward when the bullet struck; and the fact that the only fragment trail on the extant skull x-rays is the high fragment trail, which bears no resemblance to the low fragment trail described in the autopsy report.

If we are going to talk about dodges, let's talk about some of yours.

You have never tried to explain JBC's arm flip at Z226 which coincided with JFK's sudden upward movement of his arms.
You have cited numerous "experts" who say the SBT was impossible without ever saying why it was impossible.
You have continued to insist that Oswald wasn't capable of making he shots that struck JFK without ever pointing to anything in his USMC record that would indicate he lacked the skills.
You have claimed a bolt action rifle can' be fired as accurately as a semi-auto rifle, even though I've pointed out that Carlos Hathcock used bolt action rifles for his long range kill shots.

This will do for starters. If you can answer these I'll move on to some more.

Well, no, I'm not going to copy and paste several pages of their research for you, when you can read it yourself. The fact that you refuse to read their research says much about your bias and lack of credibility. 

Once again you cite people who claim the SBT is impossible without ever saying why it is impossible. To the best of my knowledge, none of these people had access to the medical evidence. All three members of the autopsy team and all but one member of the FPP who did see the medical evidence concur with the SBT. Wecht dissented from that based not on any medical evidence but on his interpretation of what the Z-film shows and the false premise that JBC was sitting directly in front of JFK and at the same level.

When I pointed out that radiology and forensic experts consulted by the HSCA noted the skull x-rays show a large amount of missing frontal bone, you erroneously claimed that the missing frontal bone was only at the rear of the bone. You clearly still have not read John Hunt's detailed article "A Demonstrable Impossibility: The HSCA Forensic Pathology Panel’s Misrepresentation of the Kennedy Assassination Medical Evidence," which I've cited to you several times.

I am under no obligation to hunt down the support for your arguments. If you have evidence of missing frontal bone other than the posterior of the bone, then post it here. I'm no going to responde to your unsupported claims because you have a habit of overstating or outright misrepresenting what the people you cite have said.
Quote

Also, Dr. Doug Ubelaker, one of the ARRB's forensic experts, noted that the amount of missing frontal bone in the AP skull x-ray is inconsistent with the appearance of the forehead in the autopsy photos, as I've mentioned to you before. When I raised this point and his observation that the autopsy photos indicate the bullet traveled from front to back, you lamely dismissed his findings because he was "only" a forensic anthropologist.

Based on what you are claiming, I'd gladly bet this clown is not a radiologist and is referring to the frontal x-ray and claiming there is bone missing from around the eye socket. I've seen people misinterpret that x-ray in the past. When I was a CT, I was duped by that x-ray as well.

That won't work because when the FPP wanted help with reconstructing the skull wounds with the skull fragments, they asked a forensic anthropologist, Dr. Lawrence Angel, for assistance, and Dr. Angel's diagrams show the missing frontal bone extending more than halfway into the frontal bone from the rear edge of the bone and clearly near where the hairline was. This is another serious problem with the autopsy photos of the head.

I'd love to see that diagram. That is completely inconsistent with the leaked autopsy photos that shoe the area of his forehead and hairline to be intact. We do see a skull flap on the upper right side of his head. I lack the expertise to say whether that flap is or is not from the frontal bone.

Dr. Mantik was eminently qualified to perform OD measurements on the autopsy skull x-rays at the National Archives, and he found hard scientific evidence that they've been altered--he was even able to duplicate how the alteration was done. And, Dr. Chesser, a neurologist who examined the autopsy materials at the National Archives and who also examined JFK's pre-mortem skull x-rays at the Kennedy Library in Boston, did his own OD measurements and confirmed Dr. Mantik's finding.

Claiming and proving are not the same thing. Funny how no one on the FPP claimed the x-rays were tampered with.
Quote

As I've pointed out to you several times now, a forensic pathologist will usually not be an expert in ballistics, radiology, and physics, much less OD measurement and analysis. Yet, you keep repeating your flimsy dodge that we should ignore all forensic-related findings made by ballistics experts, physicists, neurologists, neuroscientists, radiation oncologists, radiologists, etc., because they're not forensic pathologists.

Forensic pathologists are specifically trained to examine bodies of victims of homicides to the precise cause of their wounds. Which of these other disciplines are so trained?

I see you're still repeating the falsehood that radiation oncologists are not trained in reading x-rays. Here's what Dr. Greg Henkelmann, himself a radiation oncologist, has said about Dr. Mantik's OD research on the skull x-rays:

Unlike other evidence, optical density data are as “theory free” as possible, as this data deals only with physical measurements. To reject alteration of the JFK skull X-rays is to reject basic physics and radiology. Dr. Mantik has a PhD in physics and has practiced radiation oncology for nearly 40 years; he is thus eminently qualified in both physics and radiology. (Front matter in Dr. Mantik's book JFK Assassination Paradoxes) [/quote]

Have either Henkelmann or Mantik ever examined the victim of a gunshot wound to the head. I think we both no the answer to that.

.

If you Google the question "How much training do radiation oncologists get in radiology?", here's the answer you will get (note: nuclear medicine is a specialized area of radiology):

Radiation oncologists typically complete a 1-month formal rotation in diagnostic imaging or nuclear medicine during their 4-year radiation oncology residency. While this is the minimum formal requirement, they receive heavy, daily exposure to oncologic imaging throughout their training to master CT, MRI, and PET scans for precise tumor targeting.
Quote

There you have it. They are trained in dealing with tumors, not gunshot wounds.
Quote

Because radiation oncologists must accurately identify tumors, organs, and surrounding healthy tissues to plan radiation fields, their training integrates radiology concepts in several ways.[/font]

But no training or experience int dealing with gunshot wounds.
Quote

In short, most radiation oncologists are not full-fledged radiologists, but they receive considerable training in radiology. If a radiation oncologist becomes interested in a gunshot case, especially if he does some reading in forensic science (as Dr. Mantik has done), he can apply his expertise to reading the x-rays of the gunshot victim, and, crucially, he can do OD measurements of the alleged/identified bullet fragments in the x-rays to determine if they're actually metallic fragments and to determine their density/thickness, which is something that few forensic pathologists can do. 

And, again, while he was working as a radiation oncologist, i.e., before he retired, Dr. Mantik was licensed in radiology.   

Let me see you prove that.

Another serious conflict in the medical evidence involves the placement of the triangular skull fragment and the Harper skull fragment.

The FPP claimed that the triangular fragment and the Harper fragment marked the exit point of a bullet, and said that the two fragments adjoined one another and completed a single bullet exit hole at the coronal suture on the right front side of the skull. This is pure fiction, and the FPP's expert skull reconstruction consultant, Dr. Lawrence Angel, refuted it in his report.

This is very important for two reasons: One, the FPP falsely placed the skull fragments because they were trying to validate the cowlick entry site and to come up with a plausible exit point for the bullet. Two, the FPP falsely placed the skull fragments in order to make the head wound seem smaller and thus to seem consistent with having been caused by an FMJ bullet that struck the skull in the rear after having been fired from the sixth-floor window. 

I should start by noting Dr. Angel was well qualified to do the skull reconstruction. Noted respected researcher John Hunt:

Dr. Angel, a well-respected and experienced forensic anthropologist, assisted the FBI on many occasions, and “reported on over 565 cases and testified as an expert witness in 18 murder trials.” Angel, Curator of Physical Anthropology, National Museum of Natural History, Smithsonian Institution offered the HSCA the benefit of his considerable expertise. After examining the photographs and X-rays on three separate occasions, Angel submitted a detailed report in which he set out his anatomic relocation of the Harper and Triangular fragments. It comes as no surprise that anthropologist Angel justified his opinions by citing specific anatomic features. (https://www.history-matters.com/essays/jfkmed/ADemonstrableImpossibility/ADemonstrableImpossibility.htm)

Dr. Angel placed the Harper fragment in the rear area of the parietal bone, with most of it positioned behind the right ear. For obvious reasons, this was totally unacceptable to the FPP. Ignoring Dr. Angel's detailed analysis and diagrams, the FPP decided that the Harper fragment was at the right front of the skull and that it adjoined the triangular fragment. Observed John Hunt,

Ultimately, the FPP simply told us that the Harper fragment belonged at the right front of the skull without offering a single piece of evidence/analysis in support of that contention. The FPP lamely wrote that they “attempted to locate the correct position of these fragments,” but never elaborated on the process. Significantly, the FPP did not (and probably could not) refute or rebut the detailed analysis of the forensic anthropology expert they consulted. Nor did they bother to explain, justify, or even acknowledge their quiet, intellectually troublesome rejection of Dr. Angel’s opinions. . . .

Astoundingly, the FPP went on to leave the entirely false impression that Angel, in fact, agreed with their interpretation of the orientation of the bone fragments. Wrote the FPP:

"Anthropologist Dr. Angel's evaluation of the “Harper bone fragment” indicates that it may include a portion of the sagittal suture which is probably in apposition (corresponds) to this [skull bone] exit defect [emphasis added]." (7HSCA119)

Incredibly, the FPP claimed that Angel put the Harper fragment at the front of the head, associating it with the skull bevel. The FPP could not be more wrong. The unequivocal text of Angel’s report and the drawing attached to it leave no room for doubt: Angel placed the Harper fragment at the top rear of the head. The FPP even quote that passage from Angel’s report on page 123 of their Report!

The FPP outright misrepresented what Angel reported, then reproduced his report as an addendum to their own Report! The FPP did not bother to inform the reader that Dr. Angel completely disagreed with their interpretation of the exit wound location and the orientation of the skull fragments relative to the exit portal. (https://www.history-matters.com/essays/jfkmed/ADemonstrableImpossibility/ADemonstrableImpossibility.htm)


The FPP also ignored Dr. Angel's analysis regarding the location of the large triangular fragment. Dr. Angel located it in the frontal bone, with its front portion extending nearly to the hairline, but the FPP put the fragment in the parietal bone, on the opposite side of the coronal suture from where Dr. Angel put it!

This is a crucial issue because the autopsy photos that show JFK's face impossibly show the forehead and the front hairline intact.

Dr. Donald Thomas has also commented on the FPP's deception in their skull reconstruction and in their rejection of Dr. Angel's report and diagrams in order to shrink the size of the large head wound and to come up with a plausible exit point for the bullet. In his 2010 book Hear No Evil, we read the following:

The HSCA Forensic Pathology Panel made an attempt at a reconstruction, even though they were working under the constraint of having only unlabeled photographs and X-rays to work with. Paramount to a valid reconstruction is the accurate anatomical identification of the disembodied skull fragments. Towards this end the HSCA engaged the services of an expert in physical anthropology, Dr. J. Lawrence Angel, of the Smithsonian Institution in Washington. Angel identified the bone fragments and oriented the head wound photographs for the panel. But, for reasons known only to the members of the Forensic Pathology Panel, Dr. Angel's expert opinions were ignored. Dr. Angel's brief but succinct report is worth repeating here for two reasons. Firstly, Professor Angel was in his era one of the most respected practitioners in the field of forensic anthropology. Secondly, his analysis of Kennedy's skull wound is, in my opinion, not only authoritative, but the most accurate reconstruction heretofore available. . . . [quotes Dr. Angel's report]

For those whose eyes glazed over at or near the word "obelion," Dr. Angel illustrated his reconstruction with a hand drawing of the skull defect and the recovered fragments (Fig. 8.1). To best comprehend the difference between the true nature of Kennedy's head wound and the official versions, one can compare Angel's report with the Baden/Dox drawing published by the HSCA, purporting to illustrate the dimensions and details of the cranial defect (Fig. 8.2). Now that the autopsy photographs and X-rays have been published it can be seen that the latter drawing is deceptive, perhaps deliberately so, on the part of the Forensic Pathology Panel [FPP] and specifically that of its chairman, Dr. Michael Baden, who oversaw preparation of the illustration. (pp. 250-251)


The FPP needed to shrink the size of the head wound in order to make it appear consistent with having been created by an FMJ bullet that was fired from the sixth-floor window and that therefore struck straight on. Dr. Thomas:

The first step in cataloging the mistakes in the Baden/Dox illustration is to note the dimensions of the massive defect on the right side of the head, the exit wound according to the official version. An accompanying scale used for the trajectory analysis by the Photographic Evidence Panel gives the distance from the entrance hole in the occiput to the exit hole at the right coronal suture as 11 cm. The official autopsy report stated 13 cm as the length of this defect. However, Dr. Jay Boswell, the autopsy pathologist who made notes and drawings during the autopsy, recorded 17 cm as the greatest dimension of the wound (Fig. 8.3). Which dimension is correct: the HSCA's 11 cm, or Boswell's measurement of 17 cm? Boswell's notes have proven reliable in other instances. Inasmuch as the recovered bony fragments could not have come from a wound only 11 cm in greatest length (one recovered fragment alone was 8 cm long and 6 cm wide) the true dimensions of the wound are sharply diminished in the Baden/Dox illustration. The incredible shrinking wound effect was perhaps not without purpose. (pp. 252-253)

Dr. Thomas then notes that one of the HSCA's radiology consultants, Dr. Norman Chase, the chairman of the Department of Radiology at the New York University School of Medicine, informed the HSCA that the large head wound was "not" what he would expect "from a single, jacketed bullet hitting straight on," and then he suggested the bullet may have been tumbling or may have hit at an angle--which of course was not at all consistent with a bullet fired from the sixth-floor window at Z311-312. Dr. Thomas:

Remarks by an expert on wound ballistics, Dr. Norman Chase, when consulted by the HSCA staff for his opinion of the wound depicted in the autopsy photographs, was to the effect that,

"... the wound was massive, not the kind he would expect from a single, jacketed bullet hitting straight on; it was possibly tumbling or hit at an angle."

Evidently, this was not the sort of impression that the Forensic Pathology Panel wished to leave. (p. 253)


Dr. Thomas further notes that the FPP's deception became obvious when the autopsy materials were released, and that this deception included the FPP's bogus claim that no frontal bone was missing and that no bullet hit the skull from the front:

The deception only became evident when the autopsy photographs were made available. Examination of the autopsy photographs reveals that the broken anterior portion of the cranium included part of the lower frontal region, extending nearly to the President's hairline and not just the temporal bone as depicted in the illustration. . . .

According to the Forensic Pathology panel the right temple was the point of exit of the fatal bullet. On the contrary, for reasons detailed later, it is more likely that the "bat wing", the "devil's ear," and the notch in the right temple, are fractures and fracture fragments resulting from the impact of a missile entering the frontal bone just anterior to the coronal suture. A radiating pattern of fractures is characteristic of an entrance wound of the skull caused by a high-powered rifle bullet. One would have difficulty guessing that
there were displaced bones and massive complete fractures running in various directions from a point on the right temple if one depended on the Baden/Dox drawing. (pp. 253, 255)


Finally, I should add as an important side note that we now know that Dr. Gerald McDonnel, arguably the HSCA's most highly qualified radiology consultant, disagreed with FPP member/FPP report author Dr. James Weston about what the fracturing in the x-rays indicated about the direction of the bullet (see Hunt's discussion on this disclosure, https://www.history-matters.com/essays/jfkmed/ADemonstrableImpossibility/ADemonstrableImpossibility.htm).
