An important point that I did not include in the OP is the fact that the autopsy evidence shows two separate, disconnected wound paths in the brain, i.e., the subcortical and cortical damage to JFK's brain. There is no wound path or fragment trail between these two wound paths—in other words, these are two separate, unconnected wound paths. The cortical damage is near the very top of the skull; it is close to the high fragment trail and is on the outer (or cortical) surface of the brain. The subcortical wound path is nearly 2 inches below the cortical damage and spans the length of the brain from front to back. The first expert to note these two separate wound paths was Dr. Joseph Riley, a neuroscientist who specialized in neuroanatomy.

British researcher Martin Hay has said the following on this issue:


Since you have identified him as a research and not an expert in forensic pathology, I am going to assume he is not the latter. That means he is no more qualified to discuss the medical evidence than you or I.

You look for any excuse to avoid dealing with evidence you can't explain. Obviously, Hay was summarizing the findings of Dr. Joseph N. Riley, a neuroscientist who specialized in neuroanatomy and neuropathology and who determined from the autopsy materials that two bullets hit JFK's head. Dr. Riley had several papers published in peer-reviewed scientific journals dealing with neuroscience. He was a professor of neuroscience at the University of Florida. He wrote two articles that presented evidence that two bullets struck Kennedy's head.

Your side has never had anybody with Dr. Riley's qualification in neuroscience, just like your side has nobody with Dr. Mantik's qualifications in the science of optical-density analysis of skull x-rays, nor anybody with the qualifications of the HSCA's seven acoustical experts in acoustical science (an additional BBN acoustical scientist wrote one of the appendices for Dr. Josiah Thompson's 2021 book Last Second in Dallas). 

Speaking of the NAS/NRC panel, are you aware that Dr. Thompson reveals in his book that when the NRC/NAS panel sent BBN acoustical scientist Dr. James Barger a draft of their report, Dr. Barger replied with an 8-page critique, but the panel declined to publish his critique and did not address, or even mention, his objections in their report? Humm. . . .

I keep telling you this but it's like talking to a wall. I don't need to explain the medical evidence. I leave that to people who are qualified to do that. That doesn't include you, but that doesn't stop you from throwing your amateurish two cents into the conversation.

You love to cite people who offer opinions outside their area of expertise. None of the people you cite are forensic medical examiners which is a specific branch of medicine which requires skill sets outside of the area of radiation oncology or neuroanatomy. Neither of these fields involve the examination of gunshot wounds or more specifically, gunshot wounds to the head. How many medico-legal autopsies has Dr. Mantik performed. How many has Dr. Riley performed. Without even looking it up I'm going to take a flyer and say combined, the total number is less than one.

Your side has never had anybody with Dr. Riley's qualification in neuroscience,

Why would my "side" need or want such a person?

just like your side has nobody with Dr. Mantik's qualifications in the science of optical-density analysis of skull x-rays,

Dr. Mantik is a radiation oncologist. That is quite different from a radiologist who is an expert in reading x-rays. In fact, a radiation oncologist will often consult with a radiologist in determining the best treatment for a cancer patient under their care. Cancer care is Mantik's area of expertise. The field of medicine has many different specialties and being an expert in one does not make one an expert ina another. You are always citing people offering opinions outside their area of expertise. When your toilet gets clogged, do you call in an electrician?

It never surprises me when a CT clings to the discredited acoustical analysis since they have no real evidence on their side.

Humm. . . .

Barger's team only concluded there was a 50% probability that the recording showed a shot from the GK and that the impulses on the tape could not be proven to be gunshots. That's based solely on the acoustics and doesn't take into account the cross talk from channel 2 which indicated the shots were not made during the recording or the photo evidence that there was no motorcycle at the spot on Houston St. that Weiss and Aschkenasy presumed the motorcycle had to be.

No you don't. You cherry-pick your experts. You pretend to be qualified to decide who is a medical expert and who is not. For days on end you kept citing the HSCA FPP as an unquestionable final authority on the medical evidence--until I proved to you that several of the FPP's findings refute your version of the shooting.

Yes, you do keep making the pitiful, embarrassing argument that you don't need to explain the medical evidence, and I keep pointing out why that argument is ludicrous and why it constitutes nothing but a bunch of ducking and dodging, but you just keep repeating it without refuting my counterarguments.

You love to cite people who offer opinions outside their area of expertise. None of the people you cite are forensic medical examiners which is a specific branch of medicine which requires skill sets outside of the area of radiation oncology or neuroanatomy. Neither of these fields involve the examination of gunshot wounds or more specifically, gunshot wounds to the head.

You're still peddling this silly, inane dodge? You assume that forensic pathologists--well, those who agree with you--are the source of all knowledge when it comes to gunshot wounds, ignoring the fact that they are usually not experts in radiology, in physics, in neurology, in neuroanatomy, and in ballistics, much less in the recent science of optical-density measurement, which field did not begin to be pioneered until the 1950s and was still in its infancy in the 1960s.

Forensic pathologists are regular doctors (M.D.s) who have completed a fellowship in forensic pathology after they've been certified in anatomical or clinical pathology.

Deep down you must know that it is untenable and evasive to pretend that the findings of wound ballistics experts, radiologists, physicists, radiation oncologists, neurologists, and neuroscientists in the JFK case can be ignored just because they're not forensic pathologists. Your side still cites the research and experiments of Dr. John Lattimer, Dr. Robert Artwohl, Dr. Piziali, even though they were not forensic pathologists.

But, if you want to talk about forensic experts, let's do that.   

Have you ever heard Dr. Milton Helpern, regarded as one of the greatest forensic pathologists of the 20th century? He flatly rejected the SBT.

How about Dr. F. W. Enos? Heard of him? He was the forensic pathologist who served as the consultant to the CBS SBT wound-ballistics test. After setting up and conducting the test, he concluded that the test "disproved" the SBT and said the SBT was "highly improbable."

How about Dr. Robert Kirschner? Heard of him? The Lancet, a leading medical journal, described him as "a pioneering forensic pathologist." He was one of the ARRB's three forensic consultants. He said the SBT was "very dubious."

How about Dr. Halbert Fillinger? Heard of him? He was a nationally recognized forensic pathologist, considered a "giant" in the field, who was known for handling the most serious cases. "The Halbert E. Fillinger Lifetime Achievement Award" was named after him to recognize outstanding contributors to forensic science. Well, guess what? He scoffed at the idea that an FMJ bullet would have deposited a single fragment on the rear outer table of JFK's skull. He added that FMJ bullets will barely even leave any residue at their entry sites, much less a fragment.

How about Dr. Doug Ubelaker? Heard of him? He was a forensic anthropologist at the Smithsonian Institution and was another one of the ARRB's three forensic experts. He said the head damage in the autopsy photos indicated the bullet hit in the front and traveled from front to back.

How about Dr. Joseph Dolce? Heard of him? He was the Army's most knowledgeable expert on wound ballistics in 1964. Dr. Dolce was a battlefield surgeon in the Pacific, for three years, so, needless to say, he dealt with hundreds of gunshot victims. In 1964, he was the chairman of the Army's Wound Ballistics Board. When the WC asked the Army to provide a wound ballistics expert to be the Commission's chief expert on the subject, the Army selected Dr. Dolce. Dr. Dolce's experience and expertise were so highly regarded that if a VIP or member of Congress were injured, Dr. Dolce was asked to review the case. He had much more experience than the WC's two other wound ballistics consultants, Dr. Alfred Olivier and Dr. Arthur Dziemian. Dr. Dolce said the SBT was "impossible" and that the wound ballistics test proved this.

When Dr. Dolce informed the WC that the tests proved the SBT was "impossible," they ignored him and began to rely on the more compliant and less qualified Olivier and Dziemian. That's why Olivier and Dziemian were asked to testify but Dolce was not. 

I know you know something about Dr. Robert Shaw, who was Connally's chest surgeon. Do you know that before he operated on Connally, he had operated on more than 1,000 gunshot wounds of the chest? He, too, flatly rejected the SBT.

Have you heard of Dr. John Nichols? As a professor of pathology at the University of Kansas, he trained forensic pathologists. He, too, flatly rejected the SBT and argued that the head-shot bullet could not have been an FMJ missile.

How many medico-legal autopsies has Dr. Mantik performed. How many has Dr. Riley performed. Without even looking it up I'm going to take a flyer and say combined, the total number is less than one. Why would my "side" need or want such a person?

This is more insincere evasion. A radiation oncologist who is an expert in optical-density (OD) measurement and who is also trained in radiology and holds a doctorate in physics does not need to have performed a medico-legal autopsy to use OD measurements to determine if objects in a skull x-ray are metallic or to determine the thickness of bone in a skull x-ray. You must be kidding.

Similarly, a recognized expert in neuroanatomy does not need to have performed a medico-legal autopsy to determine the location and relationship of wound paths in autopsy photos of a brain. If anything, a forensic pathologist will consult with a neuroscientist when it comes to such matters.

Lattimer, Piziali, and Artwohl never performed an autopsy, but you guys still cite them as authorities on JFK's wounds and wound reactions. Lattimer was a urologist. Artwohl was a general surgeon. Piziali was a ballistics expert.

Dr. Mantik is a radiation oncologist. That is quite different from a radiologist who is an expert in reading x-rays. In fact, a radiation oncologist will often consult with a radiologist in determining the best treatment for a cancer patient under their care. Cancer care is Mantik's area of expertise. The field of medicine has many different specialties and being an expert in one does not make one an expert ina another. You are always citing people offering opinions outside their area of expertise. When your toilet gets clogged, do you call in an electrician?

How many times are you going to ignore the fact that Dr. Mantik is also certified in radiology? How many times are you going to ignore the fact that radiation oncologists use OD measurements as part of their job? How many times are you going to ignore the fact that radiation oncologists are trained in reading x-rays? That's part of the reason they receive their certification from the American Board of Radiology. 

BTW, Dr. Randy Robertson, a board-certified diagnostic radiologist, has concluded that the JFK autopsy skull x-rays indicate that two bullets hit JFK's head. And, several of the HSCA's radiology/forensic consultants said the x-rays show missing frontal bone, but Baden and the FPP majority ignored this fact and claimed the frontal bone was intact.

It never surprises me when a CT clings to the discredited acoustical analysis since they have no real evidence on their side.

You have no business even talking about the acoustical evidence. You haven't read one page of the HSCA's extensive materials on the acoustical evidence. You haven't read even one scholarly defense of the acoustical evidence. You haven't even read the NRC/NAS panel's report, which you cited as evidence against the acoustical evidence.

You did not realize that the NAS panel admitted that there was a 93% probability that the timing-moving correlations identified by the BBN acoustical scientists occurred because the dictabelt recorded gunfire in Dealey Plaza, and that there was a 77.7% chance that the 144.9 impulse pattern was gunfire from the grassy knoll.

Barger's team only concluded there was a 50% probability that the recording showed a shot from the GK and that the impulses on the tape could not be proven to be gunshots. That's based solely on the acoustics and doesn't take into account the cross talk from channel 2 which indicated the shots were not made during the recording or the photo evidence that there was no motorcycle at the spot on Houston St. that Weiss and Aschkenasy presumed the motorcycle had to be.

You have no clue what you are talking about, and you refuse to read anything that refutes what you want to believe on this issue. You just keep repeating these debunked talking points that you've read on some lone-gunman websites. I've read every critique of the acoustical evidence, but you haven't read any research that defends that evidence, and it shows.

The 50% probability finding was a preliminary finding that was made before they conducted the test firing in Dealey Plaza and before they had the BBN research reviewed by Queens College acoustical experts Weiss and Aschkenasy. You'd know this if you had bothered to read a single scholarly defense of the acoustical evidence.

The myth of "cross talk" from Channel 2 was answered by Dr. Barger many years ago, and new research done by BBN scientists in 2019-2020 proves that the Decker transmission is not crosstalk from Channel 2 but is an overdub resulting from the copying process.

Of course, not knowing any better, you repeat the claim that there was no motorcycle in position to record the dictabelt in Dealey Plaza. If there was no motorcycle in position on Houston Street, how do you explain the fact that even the NRC/NAS panel admitted that there's a 93% probability that the timing-movement correlations between the dictabelt impulses and the test-firing impulses occurred because the dictabelt was recorded in Dealey Plaza during the shooting?

If there was no motorcycle in position to record the dictabelt in Dealey Plaza, how did N-waves, muzzle blasts, and muzzle-blast echoes, in the correct order and interval, get recorded on the dictabelt? How is it that the N-waves occurred only in the gunshot impulse patterns? How did windshield distortions get recorded on the dictabelt only when the motorcycle was in position to record them and were not recorded when the motorcycle was not in position to record them? Figure the odds of just those distortions alone happening by coincidence.

I know you'll never read it, but for the sake of others, I again recommend my introduction to the acoustical evidence:

No you don't. You cherry-pick your experts.

The experts you claim I cherry picked  were all experts in forensic pathology. I have already acknowledged that that original team were a poor choice to perform a medico-legal autopsy but that's a mistake we just have to live with. Despite their inexperience, that were able to gather enough medical evidence so that a panel of the most respected medical experts in the country were able to conclude that JFK was shot twice with both shots coming from behind him. That dovetails with all the forensic evidence we have that Oswald was the shooter.

You on the other hand rarely if ever cite forensic pathologists to support your claims.
Quote

You pretend to be qualified to decide who is a medical expert and who is not.

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

For days on end you kept citing the HSCA FPP as an unquestionable final authority on the medical evidence--until I proved to you that several of the FPP's findings refute your version of the shooting.

My version of the shooting is that JFK was shot twice from behind with the shot to the back of the head being the one that killed him. Tell me which member(s) of the FPP dispute that.
Quote

Yes, you do keep making the pitiful, embarrassing argument that you don't need to explain the medical evidence, and I keep pointing out why that argument is ludicrous and why it constitutes nothing but a bunch of ducking and dodging, but you just keep repeating it without refuting my counterarguments.

I'm not at all surprised that you find a logical argument to be ludicrous.
Quote

You're still peddling this silly, inane dodge? [/quote}

So you think it is an inane dodge for me to acknowledge I have no expertise in the field of forensic pathology. The truth is that neither you nor I are any more qualified to analyze the medical evidence than the guy who mopped up the autopsy room floor. Your tortured analysis and reliance on people who have no expertise in the field of forensic pathology demonstrates that fact quite nicely.
Quote

You assume that forensic pathologists--well, those who agree with you--are the source of all knowledge when it comes to gunshot wounds,

They are just far more knowledgeable than a radiation oncologist.
Quote

ignoring the fact that they are usually not experts in radiology,

Neither is a radiation oncologist.
Quote

in physics, in neurology, in neuroanatomy, and in ballistics, much less in the recent science of optical-density measurement,

People in those fields are not experts in forensic medicine either unless they have been trained and experienced in that field as well. To the best of my knowledge, none of the people you cite meet that qualification, but you don't care. All you care is they offered a non-expert opinion that fits the narrative you are trying to peddle.
Quote

which field did not begin to be pioneered until the 1950s and was still in its infancy in the 1960s.

So tell us how an expert in that field is qualified to analyse the medical evidence.

You don't seem to understand that the field of medicine has a wide range of specialties, each requiring a unique skill set. When I go see my primary care physician, he has a general knowledge of medicine as a whole but when I have a specific condition, he sends me to a specialist. If I'm having an issue with my prostate (which I have in recent years) he doesn't send me to a gynecologist.
Quote

Forensic pathologists are regular doctors (M.D.s) who have completed a fellowship in forensic pathology after they've been certified in anatomical or clinical pathology.

Yes they have. Radiation oncologists and gynecologists have no specialized training in the field of forensic pathology. So why do you keep citing people outside that area of expertise?

Let's put it this way. If any of the people you've cited outside the field of forensic pathology were summoned to give testimony about a medico-legal autopsy, I doubt there is a judge in the land who would approve of that witness.
Quote

Deep down you must know that it is untenable and evasive to pretend that the findings of wound ballistics experts, radiologists, physicists, radiation oncologists, neurologists, and neuroscientists in the JFK case can be ignored just because they're not forensic pathologists. Your side still cites the research and experiments of Dr. John Lattimer, Dr. Robert Artwohl, Dr. Piziali, even though they were not forensic pathologists.

It's quite easy to ignore people pontificating about fields for which they have no expertise. If I was having trouble with my care, I would ignore the advice of my plumber unless I knew he also had training in auto mechanics.

But, if you want to talk about forensic experts, let's do that.   

That would be nice for a change.

Have you ever heard Dr. Milton Helpern, regarded as one of the greatest forensic pathologists of the 20th century? He flatly rejected the SBT.

The issues of the SBT have to do ballistics, not forensic pathology. Cyril Wecht's objections to the SBT aren't based on anything in the medical evidence. They are based on his viewing of the Z-film.

How about Dr. F. W. Enos? Heard of him? He was the forensic pathologist who served as the consultant to the CBS SBT wound-ballistics test. After setting up and conducting the test, he concluded that the test "disproved" the SBT and said the SBT was "highly improbable."

"The Halbert E. Fillinger Lifetime Achievement Award" was named after him to recognize outstanding contributors to forensic science. Well, guess what? He scoffed at the idea that an FMJ bullet would have deposited a single fragment on the rear outer table of JFK's skull. He added that FMJ bullets will barely even leave any residue at their entry sites, much less a fragment.

That is a question of ballistics, not forensic pathology. He is not commenting on the wounds but on the behavior of a FMJ bullet. Once again you cite opinions of people who haven't stayed in their lane.
Quote


How about Dr. Doug Ubelaker? Heard of him? He was a forensic anthropologist at the Smithsonian Institution and was another one of the ARRB's three forensic experts. He said the head damage in the autopsy photos indicated the bullet hit in the front and traveled from front to back.

A forensic anthropologist is not the same as a forensic pathologist. How many medico-legal autopsies has he performed in his career?

Another swing and a miss by you.

When Dr. Dolce informed the WC that the tests proved the SBT was "impossible," they ignored him and began to rely on the more compliant and less qualified Olivier and Dziemian. That's why Olivier and Dziemian were asked to testify but Dolce was not.

Quote

Have you heard of Dr. John Nichols? As a professor of pathology at the University of Kansas, he trained forensic pathologists. He, too, flatly rejected the SBT and argued that the head-shot bullet could not have been an FMJ missile.

So now you cite a pathologist on a question of ballistics. Brilliant.

You must be kidding.

You still don't seem to understand that a radiation oncologist is not an expert in radiology. I guess you think because the words are similar, they are one and the same.

Similarly, a recognized expert in neuroanatomy does not need to have performed a medico-legal autopsy to determine the location and relationship of wound paths in autopsy photos of a brain. If anything, a forensic pathologist will consult with a neuroscientist when it comes to such matters.

Funny you should mention Bob Artwohl. He came to our Prodigy forum as a CT but converted to the LN side. He credited some of the arguments I had made on the board for changing his mind.

I don't remember ever citing any of the men you mentioned for their opinions on the autopsy.
Quote

How many times are you going to ignore the fact that Dr. Mantik is also certified in radiology?

Is that a fact. No mention of that on his WebMD page. His specialties are family medicine and oncology. It says, "His dual expertise allows him to provide comprehensive primary care while also treating patients with cancer diagnoses." No mention of radiology.

You are not o for 48.

Yes, they do that after consulting with radiologists.

How many times are you going to ignore the fact that radiation oncologists are trained in reading x-rays?


No, that's what radiologists are trained to do. I'm sure he has experience looking at x-rays, but that's not his field of expertise.

That's part of the reason they receive their certification from the American Board of Radiology. 

This from the ABR websited:
"Doctors practicing in the field of Radiology specialize in Diagnostic Radiology, Interventional Radiology, or Radiation Oncology."

Do you happen see the word "OR". It doesn't say "AND". Being trained in one of these disciplines doesn't make one an expert in one of the others. I suppose its possible for someone to be certified in more han one of these specialties, but Mantiks's WebMD page makes no mention of a certification as a radiologist. One family medicine and oncology.

Your streak has extended to half a hundred.

Part of the frontal bone was missing. The POSTERIOR of the frontal bone. That means the rear of the frontal bone. That was near the temples to use a layman's term. It was not from the forehead.

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