Hi Bob
The back wound is very real, and many witnesses at the autopsy observed it, as well, and not where the WC located it. Almost unanimously, witnesses placed it 5-6 inches below the collar line, at about the level of thoracic vertebra T3, and 1.5-2 inches to the right of the spinal mid line. Whether or not there were two back wounds, as you propose, is irrelevant, as neither of them could have connected with the throat wound without going through vertebrae.
Representatives of the HSCA interviewed many autopsy witnesses in the late 70's and the contents of these interviews were suppressed until the ARRB forced their release in the 90's. At that time, it was discovered that the HSCA's summary that all of the witnesses pretty much agreed with the WC's autopsy results was a patent lie.
Now that Myth # 1 has been dismissed, let us examine Myths # 2&3.
The 6.5mm Carcano M91/38 short rifle propels a 162 grain round nosed bullet at a muzzle velocity of just under 2000 feet per second (fps). At a range of under 100 yards, which the back shot pre-z224 was, a bullet of this design and weight and travelling at this velocity has the capability to pass through two or three men, if no hard bones are encountered. And yet, there was no exit wound on the front of JFK's chest, as one would expect to see from a bullet entering at the level of T3 at a downward angle of 17°.
So, what happened to the bullet? I'm glad you asked. One popular fairy tale, and I'm sure the conspirators had a hand in its origin, is that the bullet that made the back wound only penetrated the surface of the back by an inch, and fell out somewhere on the way to the hospital or the autopsy. The reason for this, and this fantasy is still being pushed by disinfo agents 51 years later just to keep us guessing, is that the bullet was a "short shot". A short shot is a bullet fired from a defective cartridge where the gunpowder is either deteriorated or fails to ignite properly, resulting in a drastically reduced muzzle velocity.
There are two problems with this theory:
1. In order to be travelling slowly enough to only penetrate an inch in flesh, the velocity of the bullet would have to be reduced by at least 75%, if not even more. At this velocity, the bullet would not be spinning fast enough to stabilize it gyroscopically, and it would begin to tumble shortly after leaving the barrel. If it did strike JFK`s back, it would leave a messy oblong hole instead of a small round hole.
2. It is called a "short shot" for a very good reason, as the bullet will invariably land far short of its intended target. Let's say, just for the sake of argument, that Oswald had sighted the Carcano in to be accurate at 100 yards. This means that, if he looks through the scope at a target 100 yards away on level ground and places the cross hairs on that target, the bullet should hit pretty much where he is aiming, assuming a standard Carcano muzzle velocity of 2000 fps. However, should a defective cartridge rob that bullet of +75% of its muzzle velocity, it simply does not now have the "legs" to get out to where he wants it to go, and I would estimate a shot aimed at JFK's head would land somewhere about two thirds of the way to the limousine. In simple terms, a "short shot" would not have hit JFK at all, and should not even be considered when attempting to explain the back wound.
So, you're thinking, it penetrated, but did not exit. What gives? Well, you're obviously too lazy to read the thread I recommended to you, or you would be asking all the appropriate questions right about now, instead of still chasing your tail about whether or not the bullet passed through JFK's neck or not, so I guess there is nothing to do but explain everything to you from the start.
I have to go eat my supper now but I will leave you this diagram to study and I will continue later. Note, in this diagram, that the T3 vertebra is well below the top of the lungs, and a bullet entering 1.5-2 inches to the right of the spine would go directly into the top section of the right upper lung (RUL).
Mr. HILL. The right rear portion of his head was missing. It was lying in the rear seat of the car. His brain was exposed. There was blood and bits of brain all over the entire rear portion of the car. Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not, except for the one large gaping wound in the right rear portion of the head.
