Z313/The Backward HeadSnap


Recommended Posts

Obviously, since it has never been answered satisfactorly, (by either persuasion- CT or LN) there remain questions related to the "backwards snap" of JFK's head immediately after the Z313 impact.

This demonstrated effect, as observed in the Z-film, has, of itself, generated almost the same tonage of BS as has CE399/aka the "Magic Bullet".

Yet, that I am aware, not a single one of those persons who has been engaged in attempting to tell and/or sell, what it is, has ever taken the time and effort to explain the wounds to JFK's head from this SHOT FROM THE REAR, and how it is, to an almost certainty, totally responsible for what is observed in the film.

This failure to sufficiently explain the backward thrust of JFK's head is directly related to the virtual complete lack of understanding of the forces created by impact of the Z313 headshot, and as a result of this total lack of research and understanding, is not unlike many other aspects of the wounds incurred by JFK.

Rather than admit that one either has not researched the subject matter sufficiently to be able to adequately explain what is seen, or an unwillingness to just openly admit that one does not possess the capability to understand the evidence, we have the BS flying in all directions.

Not unlike the mytholigical shots which are claimed to be responsible for this reaction.

Then of course, we have those who have researched nothing, and are merely the purveyors of BS, and for whatever reason, go from place to place repeating the same old song, even if it does not actually have any lyrics which make any reason.

So, for many, who actually are engaged in answering the questions of the JFK assassination, perhaps this will aid them along.

And, I would repeat again, believe none of it without seperate and independent verification of the presented facts.

Of course, if one watches TV that much, not unlike the 4mm X 7mm deformed base to CE399 matching perfectly the 4mm X 7mm punched hole in JFK's back, most 5th graders that I am aware of could figure it out if given the facts.

It would be assumed that no one would have objections to having to re-observe portions of the evidence in order to further the efforts to understand that which apparantly misleads and confuses many.

In fact, anyone who has ever actually attempted to "follow" the WC evidence of testimony and exhibits, should know well the almost* impossibility of following along.

*Unless one happens to have access to the entire set of published documents.

"By Design", the WC has testimonies scattered in a complete "shotgun" fashion, as well as the photographic exhibits utilized in these testimonies marked and marked in no logical sequence, and thereafter too scattered throughout the volumes.

And in that regards, let it be stated without reservations, only a complete fool would ever sit down and expend the time necessary to find ALL of the little items which the WC managed to hide in this manner of evidence presentation.

(I am of the opinion that I have found only about 90+% of their ever so "slight-sleight-of-hand" manipulations.)

Back to subject matter.

The anterior/posterior autopsy X-ray of JFK demonstrates several things for us:

1. The "skull cap" section of the top/primarily parietal lobe of the skull, which can be observed in the Z-film laying over to the right hand side of JFK's head after the Z313 impact, is quite obviously back in place.

2. However, as noted in Dr. Boswell's autopsy drawing, as well as the various testimonies of Dr. Humes and Dr. Boswell, this portion of the skull was not present when they first began to examine JFK's head after having removed him from the casket.

3. The X-ray, as determined by the Clark Panel as well as the HSCA Medical Panel, established a bullet entrance wound in the upper rear area of the skull. Item "A" as marked.

Further verification of this wound of entry was found in the autopsy photograph which was, during the HSCA testimonies, shown to and discussed with Dr.'s Humes and Dr. Boswell, along with the anterior posterior X-ray.

Both of whom stated that the bullet entrance wound which they located in the vicinity of the EOP was not shown on the anterior/posterior X-ray, that they did not know what item "A" was, and that in regards to the autopsy photograph of the rear of the head, that what the HSCA was calling an entry into the scalp in the "cowlick" area WAS NOT the scalp entry which they had seen, as it was lower on the photo, down where the small amount of tissue could be seen, which was just up from the edge of the hairline.

This, of course being the lateral X-ray of JFK's head, which was also made after the "skull cap" portion, as seen after Z313 laying over onto the right-hand side of JFK's head, had been replaced.

This of course has a lot of identification, and although much of it has nothing to do with the Z313 impact and the backwards headsnap, it is ultimately all of importance and should not be left for persons to have to wonder exactly what "secret code" this is.

1. "A" represents the skull cap section of the top/primarily parietal lobe of the skull which can be seen laying over onto the right-hand side of JFK's head after the Z313 impact.

2. "a1" represents, to the best determination, the approximate point of exit of a bullet. (note)

Note: The exit point being that item marked as "B" in the anterior/posterior X-ray, and which item consists of metallic residue scraped off onto the inner table of the skull as well as the projectile penetration sidewalls through the skull, and which X-ray demonstrates that ALL skull bone, in a semicircular pattern from this exit point, forward into the frontal lobe, is now gone/missing.

Thusly, clearly demonstrating that this (point "B") is the exit point of a projectile in which the projectile and/or it's fragments travelled forward from the point of exit, and tore out/blew out that area of skull forward of the point of exit.

In addition, one can also determine that point "A" on the anterior/posterior X-ray (HSCA determined cowlick point of entry) is located within the same portion/fragment of skull as which the inner table of the skull metallic residue is located as there is no fracture line of the skull separating the two distinctive outlines.

Back to the Laterel X-ray:

3. "B" represents that portion of the skull which encompasses an area extending into the occipital lobe, and which portion of skull was fractured as a result of the EOP impact down in front of James Altgens.

This further damage to the skull was extensive due to the skull integrity being already compromised by the removal of the skull cap section as a result of the Z313 impact.

4. "b1" and "b2" represent those "radiating" fractures which Dr. Humes and Dr. Boswell found which eminated from the EOP entry and ran in various directions, thusly creating severe fragmentation of the skull in that area of the EOP entry.

This damage is clearly defined in the handwritten autopsy notes of Dr. Humes:

http://www.history-matters.com/archive/jfk...Vol17_0032a.htm

As well as being clearly shown in the drawing of the head which Dr. Boswell made during the initial phase of the autopsy.

http://www.history-matters.com/archive/jfk...Vol17_0036b.htm

In addition to the primary drawing, that small crescent shaped figure at the bottom of Dr. Boswell's autopsy drawing, represents a portion of the occipital bone which contained approximately 1/2 of the bullet penetration into the skull, and when replaced into the occipital area, complete the bullet penetration in this area.

The "line" as drawn through this fragment was meant to demonstrate the angle of penetration for the bullet/projectile which created the 1/2 of the entry hole.

Now! Most would consider Dr. DiMaio as a bonafide and certified EXPERT in the field.

High-speed bullets damage organs in ways different from what we usually think. Here is an extended passage from one of the U.S.’s foremost authorities on the subject, Dr. Vincent J. M. Di Maio, Chief Medical Examiner and Director of the Regional Crime Laboratory, County of Bexar, San Antonio, Texas (from his Gunshot Wounds, CRC Press, Boca Raton, FL, 1985)

"Implications for the physics of JFK’s head shot

Note how the bullet interacts with the head in two stages. In the first stage, the bullet passes rapidly through, leaving an expanding temporary cavity in its wake. The separate events of this first stage are (1) the bullet enters the skull by drilling a small entrance hole; (2) some brain matter is ejected backward out this hole (tail splash); (3) the bullet, beginning to tumble, passes through the brain; and (4) the bullet leaves the skull by blasting a large exit hole. Note how each of these four events transfers forward momentum from the bullet to the head (the first movement of the head).

In the second stage (after the bullet has left the skull), brain matter continues moving radially outward from the path of the bullet until the head bursts from the accumulated pressure, which can reach 100 to 200 atmospheres. Brain matter is ejected out all available openings, the largest of which will usually be the exit wound or an expanded version of it, with its size depending on how large the internal pressures became. As brain matter is ejected through the enlarged exit wound, it exerts a recoil force in the opposite direction, or backward. If this force is strong enough relative to other forces being experienced by the head at that time (which is well after the hit), the head may actually move backward (the so-called "jet effect"). If the recoil force is small relative to those other forces (such as neuromuscular reactions), the head may more in some other direction, with its motion being only modified by the jet effect.

Thus we expect a bursting head to show at least two separate movements. The first must be in the direction of the bullet, the second probably opposite to it. (Specifics of any movements beyond the first are difficult or impossible to predict, however.) In fact, JFK’s head did move twice—first briefly forward (the "snap"), then backward (the "lurch"). The quick forward motion proves that the killing shot came from the rear. The rearward motion was likely some combination of jet effect and a neuromuscular stiffening of the back muscles, which together straightened him up and threw him backward.

Could the rearward lurch have been the result of a second bullet, from the front, as implied in JFK? No, for several reasons: (1) There was only one set of wounds to the head, a tiny entrance wound in the rear and a larger exit wound on the right side/rear. (2) There is only one pattern of lead fragments in the head—a cone fanning out from the rear entrance wound to the side exit wound. (3) There was no second diffuse cloud of tissue and large fragments, as created by the first hit. (4) There was no damage to the left hemisphere of JFK’s brain, as would be required by a shot coming from the knoll, which was really to JFK’s right rather than to his front. (5) The rearward lurch was an entirely different kind of movement from the forward snap. The lurch began in the right shoulder and arm and involved the head only later. It did not look at all like the snap. (6) Because the lurch involved the whole upper torso, it required more energy than the snap. Many weapons did not have enough energy. Thus JFK’s head was hit by only one bullet, from the rear."

Certainly would appear that this guy knows what he is speaking of.

At least to me!

until the head bursts from the accumulated pressure, which can reach 100 to 200 atmospheres. Brain matter is ejected out all available openings, the largest of which will usually be the exit wound or an expanded version of it,

Now, again, being a military diver as well as a former PADI (Professional Association of Diving Instructors) Instructor, not unlike the "subcutaneous emphysema" discussions, one might say that I carry an advantage when reading this.

1-atmosphere of pressure = 14.7 psi (actually, 14.96+)

Therefore, 100 atmospheres of pressure would equate to 1,470 psi of pressure escaping out the largest/exit wound of the head of JFK.

And, if one went to the far end of Dr. DiMaio's statement of 200 atmosphere's of pressure then one would have a pressure release which reached twice this amount, or 2,940 psi of pressure release.

Therefore, in the Z-film, we observe some 1,000 to almost 3,000 pounds per square inch of internal pressure buildup within the skull escaping forward, out the larger exit wound created by the bullet and the fragments, and with this immediate and massive release of pressure from the skull, it "kicks back" in the infamous "jet effect" which is in effect the best words for it.

Thus again proving that the laws of physics remain correct, and those who dream up new versions of these old laws are merely lost within the understanding of these laws and how they apply.
