You started off sounding okay.
Now most of us all agree that there are only 2 reliable ways to quickly incapacitate.
1) The targets bleeds too much and passes out/dies.
2) The target sustains a central nervous system shot and can no longer function.
and you said...
Now option number 2 is indeed the most reliable and quickest method for incapacitating the target. Now I know there are stories out there of humans and animals being shot through the brain and are still alive. This can happen but the likely hood is really really low. I figure if a target is shot in the brain and does not die, God dont want them dead yet and no mater what you do wont matter.
which was okay except maybe for your interpretation God's desires which was a bit hokey. Then you said stuff like...
If you look at the size of the heart and spinal cord. It seems you have a much bigger target by going for the head.
and
So in summary if you really want that "majic one shot stop", I belive you should forget thorax shots and go for the head.
Okay, what part of the spinal cord is the head? Please tell me.
Simply put, the anatomy expressed is atrocious. First, you are equating the head with being the same thing as the spinal cord and because the head is larger than the heart, the spinal cord is larger than the heart and hence the head is the obvious target.
The head is not part of the spinal cord. JohnKSa touched on this last evening, but I am not sure you have a clear distinction of the parts of anatomy based on your descriptions.
Your stated goals equate the head and the spinal cord as being one in the same. As they aren't, how much of the spinal cord is in the head such that if you shoot the head you might hit the spinal cord? Very little of the spinal cord is in the head, and that is only if you include the brain stem as a structure that is part of the spinal cord. If you want to shoot the spinal cord in the head, your target is very small indeed.
The brain stem is not the spinal cord. It is structurally continuous with it, but not actually the same structure.
Since the spinal cord isn't the head, just what are you shooting in the head? As you shooting face, mouth, teeth, jaw, nose, an eye, ears, or hair? These are all valid head shots that can have absolutely nothing to do with the spinal cord, brain stem, or brain. You might damage these non-vital structures, but lots of people get them damaged and continue to fight despite God's desire. You see, being shot in non-vital areas of the human anatomy is very unlikely to produce physiological stops, which is what you are talking about. You have to hit the vital structures. You might try aiming at some non-vital structures on the outside to get at internal vital structures, but you can't equate them as one in the same.
You are mixing very generalized with very specific anatomical words and equating them as the same. When was the last time you heard a doctor refer to a brain injury as a spinal cord injury? Have you ever head of the frontal lobe of the spinal cord being damaged by a gun shot?
What you are talking about is a central nervous system shot. That is in no way the same thing as a head shot. Equating the two as a factual statement on how to effect a physiological stop is erroneous.
