hate to point this out, but this is just one more person's opinion.
Some of it is stated as opinion with qualifying terms like "appears"--particularly when trying to explain WHY psychological stops occur so commonly. However, the part I underlined in the initial quote is not stated as opinion, it is asserted as fact.
"People largely fall down when shot, and the apparent predisposition to do so exists with equal force among the good guys as among the bad guys. "
As far as it being "just one more person", that's a bit narrow. I would say that the FBI's expert on handgun wounding and effectiveness is not exactly "just one more person" when it comes to discussing handgun wounding and effectiveness.
He doesn't even mention whether he's talking about rifle or handgun cartridges.
The entire document is about handgun cartridges, hence the title.
Even so, a well placed bullet from a handgun is more than capable of stopping a human, with or without phychological affects.
I've never said otherwise, in fact that's been a common argument of mine. On the other hand, if the bullet doesn't hit anything particularly vital it won't do much of anything constructive outside of possibly garnering a psychological stop.
AND, even if it does hit something vital it can take several seconds (or longer) for the person to bleed out and become incapacitated. Platt in the Miami shootout was killed early in the fight with a shot to the chest (medical authorities indicate it was a fatal wound, unsurvivable even had he immediately received medical attention) but he survived to kill and wound several FBI agents AFTER sustaining the wound. A psychological stop would have saved lives in that case (as it has in others) but it was not forthcoming due to Platt's determination not to stop.
While there may be the added affect of psycholocal influences on a human who's "predisposed" to fall down, that in no way lessens the physical incapacitating capabilities of any particular handgun cartridge.
I didn't say it did. HOWEVER, even when a rapidly lethal hit has been administered, a psychological stop can STILL help out. If the person gives up immediately upon being shot (as most people do) then you get an instant stop instead of having to wait for the person to bleed out. The example with Platt is a good one--even though he was only seconds from being physically stopped a psychological stop (had he been so predisposed) would have helped a lot.
Most I've shot are down within 2-3 seconds.
Shooting an unsuspecting animal is very different from shooting one that is highly alarmed. An adrenaline rush can prevent the animal from going down and staying down long enough to bleed out--that is why, as you know, it is recommended that one sit and wait instead of immediately going out after shooting to retrieve the animal.
In a gunfight, a human is aware of the danger and therefore an unsuspecting animal is not a good model for what will happen with a human when shot. The alarmed, adrenaline charged animal is a better model. As you know, even a lethally wounded animal can run for quite a long distance if it is alarmed. A wound that might drop an unsuspecting animal in a couple of seconds and a few feet might allow an alarmed animal to run a long distance and even possibly be lost.
Were that not the case, the prefered shot for SD would be the hip, rather than the chest, since breaking the hip will stop an attacker on the spot.
Here's another problem with carrying hunting experience over without realizing the differences between it and self-defense. Anchoring an attacker who is still shooting at you with a firearm is of limited value. Sure, he's not going to run away now, but actually if he DID run away that would be a useful outcome for you. As it is, now you've pretty much limited his options to killing you or being killed/giving up where as before he also had the option of flight. There can be some advantages in breaking down an opponent but it can also be a disadvantage unless he's armed only with a contact weapon.
Any such affects encountered on a person should be considered a "bonus" affect, rather than a primary cause of incapacitation.
Ok, I think this is the root of your problem with what I've said. You're taking my statement of fact as if it is a recommendation rather than just an explanation of how things work.
1. Most stops are psychological. That is simply a fact. I'm not saying a person should rely on it, I'm just pointing out a fact.
2. Experts agree that you can not RELY on a psychological stop because while most people do stop for psychological reasons after being shot, many people do not. I am NOT saying one should EXPECT a person to simply give up after being shot--I'm just saying that most of the time they do.
3. Experts agree that for self-defense one should use a relatively powerful caliber (service pistol calibers are typically endorsed) and employ good shot placement. NONE of them tell people that they can count on the psychological stop even though it happens the majority of the time.
Psychological stops are a fact of life and that's a GOOD thing. But as you say they are a "bonus". We can't rely on them because they are, by definition, not reliable and that means we need to strive for physical/physiological stops which require good shot placement and are facilitated by the use of an adequately powerful caliber.
