No one is disputing shots from behind. The issue at hand still is if shots were fired from in front. The evidence of this areoverwhelmingnon-existent.
Fixed that for you

Ok. We agree, I think, that puts the knoll witnesses at 50, not 52. The Depository witnesses are still at 48.
Let's look at James Crawford's testimony, now, shall we?
He is counted as a knoll witness in your listing:
https://www.history-matters.com/analysis/witness/Sort216Witness.htm
Crawford, James _________ KNOLLBut here's his actual testimony. He names the Depository as the source of the shots and even pointed that out within seconds to his co-worker. He was diagonally across the street from the Depository, at the SE corner of the Elm & Houston intersection when he described what happened thereafter:
Mr. BALL - Did you have a good view at that point of the south exposure of the Texas School Book Depository?
Mr. CRAWFORD - I had a very good angle.
Mr. BALL - Did you see the Presidents car pass?
Mr. CRAWFORD - I did.
Mr. BALL - And just tell me in your own words what you observed after that?
Mr. CRAWFORD - As I observed the parade, I believe there was a car leading the President's car, followed by the President's car and followed, I suppose, by the Vice Presiden't car and, in turn, by the secret Service in a yellow closed sedan. The doors of the Sedan were open. It was after the Secret Service Sedan had gone around the corner that I heard the first report and at that time I thought it was a backfire of a car but, in analyzing the situation, it could not have been a backfire of a car because it would have had to have been the President's car or some car in the cavalcade there. The second shot followed some seconds, a little time elapsed after the first one, and followed very quickly by the third one. I could not see the President's car -
Mr. BALL - At that time?
Mr. CRAWFORD - That's right; I couldn't even see the secret Service car, at least wasn't looking for it. As the report from the third shot sounded, I looked up. I had previously looked around to see if there was somebody shooting firecrackers to see if I could see a puff of smoke, and after I decided it wasn't a backfire from an automobile and as the third report sounded, I looked up and from the far east corner of the sixth floor I saw a movement. It was just barely a glimpse.
Mr. BALL - Which window?
Mr. CRAWFORD - That would be the far east window -
Mr. BALL - On the -
Mr. CRAWFORD - On the sixth floor of the Texas School Book Depository. I turned to Miss Mitchell and made the statement that if those were shots they came from that window. That was based mainly on the fact of the quick movement observed in the window right at the conclusion of the report.
Mr. BALL - Could you give me any better description than just a movement? Could you use any other words to describe what you saw by way of color or size of what you saw moving?
Mr. CRAWFORD - If I were asked to describe it, I would say that it was a profile, somewhat from the waist up, but it was very quick movement and rather indistinct and it was very light colored. It was either light colored or it was a reflection from the sun. When the gun was found, or when a gun was found, I asked the question if it was white, simply because if it was a gun I saw, then it was either white or it was reflecting the sn so it would appear white or light colored.
...
Mr. BALL - Before I ask you about your [FBI] report, did you have any impression as to the source of the sound, from what direction the sound came, the sound of the explosions?
Mr. CRAWFORD - Yes; I do. As I mentioned before, the sound, I thought it was a backfire in the cavalcade from down the hill, down the hill toward the underpass.
Mr. BALL - You mean west on Elm?
Mr. CRAWFORD - Yes, and that was a little confusing and in analyzing it later, evidently the report I heard, and probably a lot of other people, the officers or the FBI, it evidently was a sound that was reflected by the underpass and therefore came back. It did not sound to me, ever, as I remember, the high-powered rifle sounding. It was not a sharp crack.
Mr. BALL - What caused you to look up at the Texas School Book Depository Building?
Mr. CRAWFORD - The sound had to be coming from somewhere; the noise was being made at some place, so I didn't see anyone shooting firecrackers or anything else and I thought "this idiot surely shouldn't do such a thing," but if they were, where were they, and if they were shots, where were they coming from, and that caused me to search the whole area on Houston Street and in front of the Texas Depository on Elm Street and then up and that's how I happened to be looking up at the time, rather than observing things in the street, probably.
Mr. BALL - Did you ever see any smoke?
Mr. CRAWFORD - No, sir; I did not.
Mr. BALL - In your remark to Mary Ann Mitchell, did you say "If those were shots, they came from that window"?
Mr. CRAWFORD - Yes.
Mr. BALL - That is what you reported to the FBI agent, also?
Mr. CRAWFORD - Yes, I suppose; at the time, I was still not absolutely sure they were shots and that's why I said if they were shots. I was basing that, I am sure I was basing that mainly on the fact of this quick movement that I observed. In other words, If I were firing the shots, I would have jumped back immediately at the conclusion of them.
Mr. BALL - Later on, did you go back in the street and talk to someone?
Mr. CRAWFORD - Yes.
Mr. BALL - Did you talk to a deputy sheriff?
Mr. CRAWFORD - Allen Swett [sic - Allan Sweatt].
Mr. BALL - What did you tell him?
Mr. CRAWFORD - I told him to have the men search the boxes directly behind this window that was open on the sixth floor - the window in the far east corner.
Mary Ann Mitchell affirmed his statement about what he said in her presence:
Mr. BALL - Tell me in your own words what you noticed and what you heard after the President's car passed; what did you see and what did you hear?I submit James Crawford is about as far from a knoll witness as you can possibly get. His first impression was a backfire from the motorcade, but by the third report, he had isolated the sounds as coming from the Depository across the street, and specifically from the sixth floor southeast corner window. He was confident enough in this at that time that he reported this immediately to his coworker, Mary Ann Mitchell, standing beside him. He then reported the TSBD's sixth floor SE corner window as the source of the shots to Deputy Sheriff Allan Sweatt.
Miss MITCHELL - Well, The President's car passed and, of course I watched it as long as I could see it but, as I remember, immediately behind it was a car full of men with the top down and quite a few of them were standing and I assumed they were Secret Service men, so after the car turned the corner and started down the hill, I couldn't see over the heads of the standing men for very long, so then I turned back to watch the other people in the caravan, whatever you call it, and probably about the time the car in which Senator Yarborough was riding had just passed, I heard some reports. The first one - there were three - the second and the third being closer together than the first and second and probably on the first one my thought was that it was a firecracker and I thought on the second one I thought that some police officer was after somebody that wasn't doing right and by the third report Jim Crawford had said the shots came from the building and as I looked up there then we realized that if the sots were coming from that building there was bound to have been somebody shooting at the people in the cars.
Mr. BALL - You heard Jim Crawford say something about if they were shots - what were his words exactly?
Miss MITCHELL - Well, I'm not sure that he said - I think he just said, "Those shots came from that building," just assuming that everybody could have figured out by then that they were shots.
Mr. BALL - Did you look at the building?
Miss MITCHELL - Yes; I did.
Mr. BALL - Did you see anybody in any of the windows?
Miss MITCHELL - I don't remember. I understand there were some porters that were leaning out of the fifth floor windows but I don't remember whether I saw them or not. I know where I thought he was pointing and where I was looking I couldn't see anybody so I never was sure which window he thought he was pointing to.
I will tell you I am very comfortable calling him a Depository witness, not a knoll witness. Your source claims he's a knoll witness. Why? Apparently because he heard hoofbeats and thought horses, not zebras. Or actually, thought "backfire" at the first report and not "assassination attempt".
And I will point out that if he's a Depository witness, not a knoll witness, then we need to increase the Depository witnesses by one to 49, and decrease the knoll witnesses by one to 49 (we previously agreed Davis and Kounos were not knoll witnesses).
So that makes the count 49 to 49. Right?
Hank
I asked for your source where you found that deceberate reflexes are delayed with aproximatly 0.3 seconds.http://mcadams.posc.mu.edu/headwnd.htm
4. Werner U. Spitz, M.D., forensic pathologist, Chief Medical Examiner, Wayne County, Michigan: "7. It is impossible to conclude from the motion of the President's head and body following the head shot, from which direction the shots came. There is no doubt that as soon as the President was struck in the head, death occurred. The President's body was thus limp, devoid of control and stability normally exerted by the cerebral centers. Nothing would keep the body up at this stage and a forward drop is likely to occur. The subsequent backward movement of the President's head can be explained by sudden decerebration. This position is well known as "decerebrate posture" and is characterized by opisthotonos, a tetanic spasm -- or seizure-like condition."
5. Richard Lindenberg, M.D., Director of Neuropathology and Legal Medicine, State of Maryland: "Immediately after the shot through the head the President took rather abruptly an almost erect position before slumping over to the left. This straightening is to be considered a sudden opisthotonic reflex movement due to decerebration."
Human reaction time is about 1/3 of a second, and reflex action is immediate. Therefore, we can expect decerebrate reflexes within human reaction time (less than 2 Zapruder Frames) of bullet impact
Yes, but to keep it simple lets use decerebate reflexes as a group name if you don’t mind.Which are also known as decerebrate posturing, decerebrate response, decerebrate rigidity, and extensor posturing.
So, if your estimate is correct, how do you explain the head movement forward a little bit more than two inches between Z312-313, if the bullet hit at the end of Z312?The world does not happen in fraction of a second snapshots, but the limitations of a movie camera is that it can only show the world in fraction of a second snapshots. This is as true now with a digital camera as it was back in 1963.
Unlike most of the home movie cameras of the time, which used a rotating disk as a shutter, Zapruder's Bell And Howell 414PD movie camera used a proper camera type shutter. It had an exposure time of 1/40th of a second (25 milliseconds) per frame. The implications of this is that for every frame cycle of 1/18 of a second (56ms) the shutter is closed for 31ms (film sees no image). The bullet is likely to have impacted some time during the 31 ms closed time between Z312 and Z313, since there appears to be no evidence of impact in Z312
But you didn’t answer my question?No, not quite.
The bullet fragments when it strikes the bone at the back of JFK's skull. Some of the kinetic energy is dissipated at the point of impact (which is why Kennedy's head moved forward between Z312 and Z313). However, the fragments still carry a lot of kinetic energy, and most of that energy is dissipated in the form of shock waves and a pressure cavity. When a high velocity bullet strikes the the head, penetrates the skull and moves through the brain, pressure changes of as high as 1500 psi or higher can develop. There are three types of pressure change
1. the shock wave or high pressure pulse formed when the bullet strikes the head;
2. very high pressure regions form immediately in front of and all around the moving bullets or bullet fragments
3. relatively slow, low pressure changes which cause a large explosive temporary cavity to be formed behind the bullet or bullet fragments.
In the case of the head, the pressure is pushing out, but the skull is closed, then the cavity collapsed. The pressure is too much of the skull to cope with, and it explodes

In addition, I submit this, a gif made by a poster called "William Seger" (who is also a member here). The first time I saw it was a post by him made at "Democratic Underground" about five years ago. I don't usually like to plagiarise, but in this case I will, because I cannot say it any better than he did, so I will quote from his post (my emphasis)
[qimg]https://www.dropbox.com/s/madug7efr9b9e2c/z310-317.gif?raw=1[/qimg]
Here's one that shows a couple of previous frames (to prove there was no forward motion before frame 313), and several frames after that to show why the back-and-to-left cannot be explained by momentum from the bullet because it comes 1/6 second after the hit and it shows acceleration over several frames, which implies a continued force long after the bullet is gone:
So, if your estimate is correct, how do you explain the head movement forward a little bit more than two inches between Z312-313, if the bullet hit at the end of Z312?
1. Do you mean that the ”explosion” at the top right of JFK’s head in Z313 is like ’pushing’ the head back and to the left?
2. Or do you mean that a jet recoil effect is causing said movements?
You can’t see that the back spatter is shooting out backwards against the bullets trajectory at the instant it hits the gel block?Utter rubbish
The spatter is a result of the pressure cavity, which travels behind the bullet!
Watch this again
[qimg]https://www.dropbox.com/s/x4lisdkhwy55k9h/Bullet%2BGel.gif?raw=1[/qimg]
Have you meassured this acceleration?No. JFK's head accelerates backwards after Z313. If the movement backwards was the result of transferred momentum from a shot from the front, then that cannot happen, acceleration requires a force to be applied. What is the force causing the acceleration?
No. Based on a not proven assumption, conjuring from that.No. Based on simple observation
So why did WC/FBI/LIFE/CIA suppress the fact that the Z-film showed JFK’s head snap violently back and to the left when hit by a fatal bullet? Because the Z-film corroborated their conclusion of only two bullets from behind?
Isn’t that a bit, counter productive?
No one is disputing shots from behind. The issue at hand still is if shots were fired from in front. The evidence of this are overwhelming.
Point is. IF there was/is a cover up of more than one shooter, of course you will not find ”physical” evidence laying around for everyone to pick up.
Occipital bone = lower part of the back of the head. Not a trace of this wound in the x-rays.
The HSCA acoustic evidence show one rifle shot from the knoll exactly at frame Z313, so no, it didn’t miss.
The DPD sent out a description on the radio of a suspect man with a Winchester 3030 minutes after the shooting. No one knows who gave that description or from where. Gone.
The point I’m making is that everywhere you look, you see broken, dodgy or non existent chain of custody. This is the case with almost all the technical evidence. Even more alarming is that much of it has to be willfully fabricated since ’honest mistakes’ can’t be the explanation.
Time and again. Everywhere you look.
Why is that?
You can’t see that the back spatter is shooting out backwards against the bullets trajectory at the instant it hits the gel block?
Look again.
Have you meassured this acceleration?
Show me.
No. Based on a not proven assumption, conjuring from that.
That is 11th century teleology.
IF a ”knoll witness” equals someone who places the shooter specifically on the knoll, that is.
Bravo. That wasn't too hard, was it?
I have seen your point since day one, Hank. Don’t you worry about that. Loud and clear.You're starting to see my point,
No. No manipulations. Since ”the grassy knoll” is a world famous meme catching on only months after the event it is not to be expected that witnesses far from said knoll pinpoint the source as ”the (grassy) knoll”. Since the knoll was/is perfectly alligned in between the ”viaduct” and where the ladies stood, the direction is the same.that the data has been manipulated in those lists to increase the overall count of knoll witnesses and decrease the overall count of TSBD witnesses.
So with this admission, we've gone from 52 knoll witnesses to 50. Right?
Yes ”we” are. 52 witnesses hearing shots from the (direction) of the knoll, still stands.We were never at a majority as per your original remarks. Over time you've come down on that claim as well.
Knoll, as the source, is wrong.I pointed out your various claims concerning the percentage of knoll witnesses were not true in this post: http://www.internationalskeptics.com/forums/showpost.php?p=12291889&postcount=3184
So we're making real progress here. You're admitting your conspiracy site source didn't properly vet their list. You're admitting the list is inflated. And we've shown your claims about the relative percentage of knoll witnesses wasn't true either.
Hank
52 witnesses said the position/direction of the knoll.
Have you meassured this acceleration?
Provide the links and I address, no worries.I guess you're too busy digging your hole to nowhere to address my earlier posts,
so I'll address the 1st bolded nugget of nuttiness.
The blood mist that exits a entrance or exit wound doesn't meet or exceed the velocity of the penetrating projectile - blood spatter defined as "high velocity" is generated by projectile impacts as low as 100 feet per second. The volume of ejected blood spatter can be greater with a higher velocity projectile than a lower velocity projectile but the potential velocity of ejected blood (liquid is substantially different than a solid for the purposes of acceleration) can not equal or exceed projectile velocity.
https://www.ncjrs.gov/pdffiles1/nij/grants/241744.pdf
No, just courtesy.Is the second bolded intended to create dramatic tension or just drama?
Does it now?Science profoundly rejects manifesto's bare assertion of blood spatter travelling faster than the bullet itself.![]()
Wrong. https://www.maryferrell.org/DealeyPlazaWitnessDB.html#page=survey216
That information is incorrect
So why did WC/FBI/LIFE/CIA suppress the fact that the Z-film showed JFK’s head snap violently back and to the left when hit by a fatal bullet? Because the Z-film corroborated their conclusion of only two bullets from behind?
Isn’t that a bit, counter productive?
What forensics?
The very few that are still around, maybe. Could be fake.
Could be of JFK after they restored him for the funeral.
Proven forgeries.
Which ”terminal ballistics” are you talking about?
No one is disputing shots from behind. The issue at hand still is if shots were fired from in front. The evidence of this are overwhelming.
There are reports of bullet marks on the pavements and one photo of what looks like an officer in civil clothes picking up something small from the grass south of lower Elm Street.
Point is. IF there was/is a cover up of more than one shooter, of course you will not find ”physical” evidence laying around for everyone to pick up.
That said, mistakes were made and little pieces here and there slipped through the net. The Harper fragment is a good example, found by a medical student in the grass south of Elm the day after the assassination. He gave it to his relative, Dr Harper, working as a forensic pathologist at Methodist Hospital in Dallas.
The fragment was a 7x5 cm cranial fragment of occipital bone and at the most a day old. They photographed it, wrote a report and gave it to the Secret Sevice in Dallas never to be seen again. Luckily they kept copies of the photographs and of their written report. Three forensic pathologists.
Occipital bone = lower part of the back of the head. Not a trace of this wound in the x-rays.
The HSCA acoustic evidence show one rifle shot from the knoll exactly at frame Z313, so no, it didn’t miss.
One fatal rifle shot from the knoll was enough, wasn’t it?
I suppose you have scientific meassurements and empirical tests on blindfolded subjects to back this up?
Did he belong to the group of officers who found the alleged murder weapon?
Did he belong to the group of officers who found the alleged murder weapon?
Did he belong to the group of officers who found the alleged murder weapon?

Why is that?
~ Fiester, Sherry P, 2012.
Does it now?
Warren Commission Exhibit 390 demonstrates Canadian blood spatter analyst, Michael J. Sweet (1954-2006) published research regarding the velocity of blood projected from forceful impact. Utilizing human blood, Sweet’s research documented blood leaving the point of the impact travelled 3.59 times faster than the velocity of the impacting object (Sweet, 1993).
~ Fiester, Sherry P, 2012.
It is not the ”amount” I’m talking about, it’s the instant effect of back spatter.A tiny, tiny amount.... nowhere near as much as you are claiming for the JFK headshot
Instead of questioning me and my skills in this and that, explain what you are complaining about.I can see that you have utterly no clue about terminal ballistics. Do you even own or have you ever even fired a firearm.
The gel for mimic human tissue and soap for blood/fluids.Utter rubbish.
Why do you think forensic ballistics experts use ballistic gel and ballistics soap in their testing? Go on, look it up.
I wrote this earlier.Looks like you know nothing about 9th grade physics either.
Acceleration requires a force to be CONTINUING to act on the object while it is accelerating. When a bullet strikes an stationary object it accelerates MOMENTARILY, then there is no further force acting on the object, so it decelerates. JFK's head continues to accelerate (the spacing of the head position increases between consecutive frames Z314, Z315, Z316, Z317). This shows that there MUST be a force acting on his head. That cannot be from an impact - take your foot off the gas and your car decelerates.
So, what caused the violent thrust back and to the left?No. There was no impact from the front, there is no evidence to support that. Pure conjecture on your part
So, if ”simple observation” is enough, why did the authorities surpress the info in the Z-film showing JFK’s head violently being thrown back and to the left when hit by a bullet?No, just simple observation.
Since ”the grassy knoll” is a world famous meme catching on only months after the event it is not to be expected that witnesses far from said knoll pinpoint the source as ”the (grassy) knoll”.
Since the knoll was/is perfectly alligned in between the ”viaduct” and where the ladies stood, the direction is the same.
If you refer it back to Z313, all the spatter would have disappeared from the frame by Z314... at 1/18th of a second frame rate, by Z314 all the spatter would be 459 feet away.
why did the authorities surpress the info in the Z-film showing JFK’s head violently being thrown back and to the left when hit by a bullet?

== QUOTE ==
In the final chapter, “Truth Shall Prevail,” Paul Joseph Barnett and James C. Kaufman stress that scientists are searching for the truth, sometimes at great personal cost. “Humility, or a reticence to speak in absolutes, is the single greatest distinction between the sides of pseudoscience and evidence-based science.” They add, “Responding to pseudoscience takes its toll. Scientists get frustrated when they have to repeat facts, refute the same fallacious arguments, and end up in defensive positions because their detractors are not bound to the same rules. Like nuisance lawsuits, pseudoscience rarely plays to win; the goal is simply not to lose. Getting people to doubt science counts as a victory.”
