Euthanasia By Gunshot

The weapon muzzle should be held 2–10 inches from the intended point of impact.

Method: Gunshot

Pros:

If done properly, it's reliable, instantaneous, externally bloodless, and humane.

it's recommended that the muzzle be held 1 to 12 inches away.

Now! Those of us who were raised around the slaughtering of hogs and cows for ourselves, as well as working around some of the local slaughterhouses, have been aware of this method of killing the animals for years.

And, as dumb as we may be, we are not so dumb to stand only approximately 1-foot from an animal and shoot it in the head merely to be covered in "backspatter" of large amounts of blood and cerebral tissue.

And, it is most unlikely that any Vet is that dumb either!

But, since large amounts of blood and cerebral tissue do not go backwards from the point of entry of the bullet, there is truely no problem with the recommended procedure, which happened to be the standard method of excecution for livestock until the "bolt-gun" became available.

And even then, the bolt-gun was only utilized in those areas which slaughtered on a massive scale.

So, not unlike most of the other "good ole boys" down here in south MS, I have shot many a cow and hog in the head with a rifle, and have yet to receive sufficient "backspatter" to even notice it.

And, had those who were dumb enough to believe this "backspatter/aka one bullet from the right front, paid attention, they could have easily derived the facts from the presented information.

For an appreciation of the distribution and dimensions of these stains, the adjacent photograph was taken through the viewfinder of a special magnifying device. The reference ruler measures in .02mm increments. The larger stain adjacent to the reference ruler is .04mm in diameter.

These stains are part of a back spatter pattern taken at 6 inches. The ammunition used was a Winchester .357 Magnum SPG, 180 grains, with a velocity of 1180 fps from muzzle, and 556.40-ft lb kinetic energy.

-----------------------------------------------------------------------------------------------------------------------------------------------

1. Six inches back from the point of entry, a "backspatter" stain which measured 0.04 mm could be seen.

Well, hate to be the one to inform, but 0.04mm equates to 0.00156 inch. Or, slightly over 1 thousandth of an inch.

And, this was the largest stain!

In fact, the "backspatter" stain is so minute and scattered, that it took photography through a special microscope in order to even be able to see it.

The stain is in fact so small that the naked eye would most probably not have even seen the "mist", had one been standing directly adjacent to the backspatter when it was formed.

2. One should also truly pay attention to the impact size of the projectile which it took to create this fantastic backspatter stain as well.

It happened to take a .357 Magnum round impact (9.15mm bullet) to create this amount of backspatter, whereas the Carcano bullet is only 6.5mm/.254 inch in size.

That is no doubt why most Vet's do not recommend anything above 9mm for shooting animals.

Shoot a cow in the head with a .45, and expect to get back-spattered with blood.

And anyone dumb enough to utilize a 12-gauge slug will be in need of an immediate bath.

--------------------------------------------------------------------------

But nevertheless, this fantastic amount of "backspatter", as created by the frontal strike of a bullet to the head of JFK, was caught on extremely poor quality film, not only on the Zapruder film of some 75 feet distance away, but also on the Nix film of over 200 feet distance.

And, it has thereafter been identically replicated utilizing bloody sponges, which were shot with considerably larger bullets, which ulitmately at a 6-inch distance from target impact produced a backspatter stain of such proportions that it takes a special microscope to even locate and see it.

Let's see now! We have Bill Miller who believed this nonsense, as well as Al Carrier.

Would anyone else who actually fell for and believed this, please raise their hand and move over to be seated with Miller and Carrier.

Hey Miller!

Someone ask/tell you to "not respond" and hopefully let this topic die of natural causes?

Rest assured that it will die! However, it will be moreso due to demonstrated ignorance on the part of those who believed it, than by any interpretation of factual information.

http://jfklancerforum.com/sherryg/page05.html

"The target sponge would correlate to tissue and bone."

Exactly what level of intelligence is of the opinion that a wet/bloody sponge has any basis for comparison with the scalp; skull; and cerebral tissue of a human being????

One could have at least shot a stray cat or dog, or even gone to the stockyard and bought a hog or two.

Provided of course that one were actually attempting to "replicate" something in an honest attempt to get at the factual truths through comparative analysis.

"Like the targets in the experimental shootings, the Zapruder film also demonstrates a pronounced and violent movement of the President's head to the rear, in agreement with the laws of physics (35)."

http://karws.gso.uri.edu/jfk/scientific_to...high-speed.html

"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."

It would appear that someone has an extremely limited understanding of the laws of physics.

Especially if they are under some misguided impression that sponge can build up some 1,400 to 2,900 PSI of pressure within it's body.

Last time that I checked, a sponge actually will hold ZERO pressure buildup.

Am I missing something here in this "Comparative Analysis" reconstruction???????

Better yet! Are you missing something??

Anyone seen Bill Miller?

This topic somewhat reminds me of the old TV Commercial:

"Give it to Mikey, he'll eat anything!"

Let's see now! We have Bill Miller who believed this nonsense, as well as Al Carrier.

"I am Bill Miller, a long time researcher of the Kennedy assassination. My main interest are in the realm of the photographic record and the witnesses statements and testimonies. I have studied the case for over 25 years and I have received the Mary Ferrell Award presented for the discovery of new evidence in the JFK assassination murder case."

Personally, I would be somewhat ashamed to post that I had "studied" this case for some 25 years and yet still knew as little about the subjects stated..

You certainly can not know that much about the witness statements and testimonies, or elsewise you most assuredly could not readily accept that Z313 was the last shot fired.

As to the "photographic record"!

http://mcadams.posc.mu.edu/russ/testimony/shaneyf2.htm

Mr. SHANEYFELT. Yes; we have established that the Zapruder motion picture camera operates at an average speed of 18.3 frames per second.

http://www.jfk-info.com/durn1.htm

F-STOP

The second value to determine is the f-stop. The f-stop indicates the amount of light the lens and iris are sending towards the film. Zapruder used film with a speed rating of ASA 25 (Kodachrome II). Zapruder's camera had an "electric-eye" that automatically opened or closed the iris depending on light conditions. The film appears properly exposed, so we can assume the f-stop was close to optimal.

------------------------------------------------------------------------------------------------------------------------------------------------

http://jfklancerforum.com/sherryg/page04.html

The videotape used to capture patterns as they were created records 30 frames per second. The video utilized approximately 4-5 frames to capture the forceful impact pattern when a low velocity, large caliber projectile with a high KE rate impacted a large volume of blood. This means that particular pattern was created in its entirety in 1/6 of a second. Some patterns were created in less than 1/6 of a second.

------------------------------------------------------------------------------------------------------------------------------------------------

Perhaps our "GURU" photograhy expert will take the time to explain the difference in film ratings for a film which basically runs at a maximum camera speed of 18.3 frames per second and a camera which can film at a rate of 30 frames per second.

Furthermore, it is noted:

"The video utilized approximately 4-5 frames to capture the forceful impact pattern when a low velocity, large caliber projectile with a high KE rate impacted a large volume of blood."

So! We used a wet bloody sponge, shot it with a "large caliber projectile", filmed it with a camera which ran at 30 frames per second, and thereafter claimed a VALID EXPERIMENT!

For the enjoyment of the reading public, perhaps the author will demonstrate those distances at which the camera was placed away from the wet sponge target in order to caputre the miniscule backspatter which is recorded in this article.

"For an appreciation of the distribution and dimensions of these stains, the adjacent photograph was taken through the viewfinder of a special magnifying device. The reference ruler measures in .02mm increments. The larger stain adjacent to the reference ruler is .04mm in diameter."

Personally, I fully appreciate exactly how small .04mm is. It happens to be 15.6 thousandths of an inch, which the naked eye would have difficulty observing unless there was an entire bucket of it thrown up into the air.

I found a camcorder online and it films at 30 frames per second and i was just wondering if that was good enough to film quality videos

-----------------------------------

Short answer is yes.

Explanation:

All NTSC standard-definition camcorders shoot at 30 fps. It's simply the standard. Technically, it's 29.97, but we usually just say 30.

Some standard frame rates:

NTSC standard-def: 29.97 fps

PAL/SECAM standard-def: 25 fps

Film: 24 fps

You won't find anything better without jumping up to high-definition, and you won't find anything worse without going to cameras shooting at non-standard frame rates

---------------------------------------------------------

its about as good as it gets... 30FPS is very high quality... consider this: Major Motion Pictures filmed in Hollywood are shot at 24FPS... so 30 is even better than that!

----------------------------------------------------------

In continuation:

http://jfklancerforum.com/sherryg/page04.html

Collection of Data

Data collection for the analysis was accomplished by shooting through a variety of samples of whole human blood (19), at a series of distances (20) and with a wide diversity of projectile caliber (21).

http://jfklancerforum.com/sherryg/references.html

20. The distances the paper targets were placed in front of and behind the target blood were 6 inches, 12 inches, 18 inches, 24 inches, 36 inches, 48 inches, 60 inches and 72 inches.

---------------------------------------------------------------------------------

Perhaps in someone's mind, the distance at which the paper targets were placed from the actual target, have some bearing on "shooting distances'", but not in my limited conceptual understanding.

As well as the complete failure to demonstrate exactly what bullets fired at what distances even managed to make the miniscule "backspatter" stains (.04mm in size) on a paper target at WHAT? distance?

-----------------------------------------------------------------

http://jfklancerforum.com/sherryg/page05.html

Page 5: Evaluation of Data

The results of the experiments are as expected, since physics was used to reach the anticipated results. The results were consistent, regardless of changing variables such as blood volume and projectile velocity. The results were reproducible using a wide range of weapons and caliber projectiles.

Therefore, the experiment results were determined to be reliable and credible.

-------------------------------------------------------------------------

By what standard?

"Mickey Mouse" does not count!

----------------------------------------------------------------------------

http://jfklancerforum.com/sherryg/page06.html

"Therefore, it is my opinion the bloodstain evidence is consistent with the injury to John F. Kennedy's head being the result of a single gunshot from the right front."

--------------------------------------------------------------------------------

Irrelevant of the fact that:

1. Several of the most qualified references state otherwise.

2. Bullet fragments flew forward in the Presidential Limo.

3. Large amounts of cerebral tissue blew forward over Nellie and JBC.

4. There exists within the skull of JFK an exit wound in which the bullet was traversing from rear to forward.

5. Portions of the bullet fragments found in the front seat area of the Presidential Limo were ballistically matched to the Carcano Rifle found on the sixth floor of the TSDB.

Along with: The fact that this "Comparative Analysis" is completely worthless in means; methodology; as well as data interpretation.

Let's see now! We have Bill Miller who believed this nonsense, as well as Al Carrier

Collection of Data

Data collection for the analysis was accomplished by shooting through a variety of samples of whole human blood (19), at a series of distances (20) and with a wide diversity of projectile caliber (21).

http://jfklancerforum.com/sherryg/references.html

20. The distances the paper targets were placed in front of and behind the target blood were 6 inches, 12 inches, 18 inches, 24 inches, 36 inches, 48 inches, 60 inches and 72 inches.

---------------------------------------------------------------------------------

Perhaps in someone's mind, the distance at which the paper targets were placed from the actual target, have some bearing on "shooting distances'", but not in my limited conceptual understanding.

As well as the complete failure to demonstrate exactly what bullets fired at what distances even managed to make the miniscule "backspatter" stains (.04mm in size) on a paper target at WHAT? distance?

Page 5: Evaluation of Data

The results of the experiments are as expected, since physics was used to reach the anticipated results. The results were consistent, regardless of changing variables such as blood volume and projectile velocity. The results were reproducible using a wide range of weapons and caliber projectiles.

Therefore, the experiment results were determined to be reliable and credible.

-------------------------------------------------------------------------

By what standard?

"Mickey Mouse" does not count!

"Therefore, it is my opinion the bloodstain evidence is consistent with the injury to John F. Kennedy's head being the result of a single gunshot from the right front."

--------------------------------------------------------------------------------

Irrelevant of the fact that:

1. Several of the most qualified references state otherwise.

2. Bullet fragments flew forward in the Presidential Limo.

3. Large amounts of cerebral tissue blew forward over Nellie and JBC.

4. There exists within the skull of JFK an exit wound in which the bullet was traversing from rear to forward.

5. Portions of the bullet fragments found in the front seat area of the Presidential Limo were ballistically matched to the Carcano Rifle found on the sixth floor of the TSDB.

Along with: The fact that this "Comparative Analysis" is completely worthless in means; methodology; as well as data interpretation.

Let's see now! We have Bill Miller who believed this nonsense, as well as Al Carrier

http://jfklancerforum.com/sherryg/page05.html

Like the targets in the experimental shootings, the Zapruder film also demonstrates a pronounced and violent movement of the President's head to the rear, in agreement with the laws of physics (35).

The following is from Wecht's testimony at the Menendez retrial. See:

Q ISN'T IT YOUR UNDERSTANDING, THOUGH, AS

9 A MATTER OF PHYSICS -- I KNOW YOU'RE NOT AN

10 ENGINEER, BUT AS A MATTER OF PHYSICS, WOULDN'T -- IF

11 YOU IMPART A FORCE IN A SPECIFIC DIRECTION, ISN'T

12 THERE A TENDENCY TO MAKE THE OBJECT THAT IS STRUCK

13 TRAVEL IN THE SAME DIRECTION UNLESS THERE'S A REASON

14 TO BE THROWN IN A DIFFERENT OBJECTION?

15 A SURE.

16 MS. ABRAMSON: OBJECTION. WELL, I'M GOING TO

17 OBJECT TO THAT AS IRRELEVANT UNLESS THE OBJECT WE'RE

18 TALKING ABOUT IS PART OF THE HUMAN BODY.

19 THE COURT: OVERRULED.

20 THE WITNESS: THAT'S ONE, I THINK, OF THE

21 BASIC NEWTONIAN PRINCIPLES OF LAWS OF PHYSICS;

22 HOWEVER, YOU SEE, WHEN YOU DEAL WITH THESE THINGS ON

23 A PURELY ENGINEERING BASIS, YOU'RE FORGETTING THAT

24 THE HUMAN BODY HAS MOVEMENT AT JOINTS AND YOU'RE

25 FORGETTING THAT THE HUMAN BODY HAS MOVEMENT THAT IS

26 CONTROLLED VOLUNTARILY OR EVEN INVOLUNTARILY BY THE

27 PARASYMPATHETIC NERVOUS SYSTEM.

28 SO, YOU KNOW, THAT'S THE PROBLEM IN

1 TRYING TO DEAL WITH SOMETHING LIKE THIS FROM A

2 PURELY MECHANICAL ENGINEERING OR PHYSICIST

3 STANDPOINT. SOME OF THE CONCEPTS, INDEED, ARE

6 SYSTEM AND SO ON, ALL OF THE VOLUNTARY AND

7 INVOLUNTARILY REFLEXIVE ASPECTS OF IT, AS WELL AS

8 WHAT SOMEBODY SETS OUT TO DO IN THIS KIND OF A

10 AND HERE, YOU KNOW, SIR NEWTON AND

11 OTHERS JUST NEVER DEALT WITH THOSE THINGS. THEY

12 DEALT WITH STATIONARY OBJECTS MOVING IN A CERTAIN

13 FASHION WHEN OTHER OBJECTS STRIKE THEM OR ARE STRUCK

14 BY A MOVING OBJECT, AND THAT'S JUST A VERY DIFFERENT

15 SITUATION.

. 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").

(emphasis added)

--------------------------------------------------

And there, we have the correct application of the laws of physics.

1,400 to 2,900 PSI of internal pressure created within the cavity of the skull, being suddenly allowed to release out the large frontal exit wound, literally "kicks" the head backwards.

At the same instance, the expanding pressure continues to fracture and fragment the skull, which causes the right temporal area of the skull to rupture and separate to the side (along with the skull cap section), and we now have this extremely high pressure buildup within JFK's skull being released from the frontal as well as the right temporal area.

With the end result being JFK's head being "thrust" backwards and to the left!

Merely simple "rocket science"!

How ridiculous of you to start a thread like this. You have no forensic blood spatter expertise, so what do you do ... you single out a case that has nothing to do with the issue of exploding debris that occurs when a bullet slams into the brain matter. There are some simple basic laws of science that cannot be disputed and Sherry, who by the way has a far more detailed resume than a mere 40 hours of training, has reported to us how those rules of physics apply to blood spatter science. I am still waiting to hear you come up with one expert who has seen her work and dispute what she has written. Instead ... all you have done is try to cloud the issue with propaganda. In fact, I have noticed that you tend to start a lot of threads that really could and should have been limited to just one thread. I am only waiting for you to post some new threads that say something like 'blood spatter science ... I have no expertise in it but feel that I know more than those that do' - 'blood spatter science ... can we get around it by avoiding it' - 'blood spatter science ... only applies to those who are smart enough to understand it'. Let me know if you need more alike topics so to propagandize your agenda.

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

http://karws.gso.uri.edu/jfk/scientific_to...high-speed.html

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!

Tom, it was only a few months back I busted someone on Duncan's Forum doing this exact same thing... I didn't realize he was imitating YOU. The quote you supply DOES NOT come from DiMaio. It comes from Ken Rahn. On his website, Rahn quotes DiMaio extensively, and then, NO LONGER in quotes, adds his own input. He, of course, is not an expert on wound ballistics or bloodspatter analysis. In any event, the quote you attribute to DiMaio comes exclusively from the section written by Rahn.

The dead give-away, if you need one, is the discussion of the film JFK. DiMaio's book was written years before it was released.
