"One Shot Stop" Handgun statistics, and why they're a load of crap

In my last CCW class, I had somebody talk about the famous “Marshall & Sanow One Shot Stop Statistics” and about how this student was going to use a 97% round instead of a 92% round. 

 

Okay, if you aren’t familiar with these, basically these two guys, Marshall & Sanow, supposedly looked at a ton of actual shootings, where people had been shot once in the torso with a bullet, and then they measured what percentage of those resulted in an immediate stop, i.e. immediate cessation of hostile action.

 

Then they published their work, and all bullets were rated.  Immediately, people who were not given to critical thinking, accepted these percentages as gospel, and you could hear people arguing at gunshows and on the interweb about how they’re more tactically saavy because their handgun load was a 94% stopper, while yours was a meager 82% stopper.

 

Over time the flaws in this stuff became apparent, and luckily we don’t have to hear about it as often as we used to.  But it still pops up once in awhile. 

 

Let’s break this down as to why this idea is massively flawed.  First, assuming that their data was not fabricated (because of lot of the shootings weren’t documented by anybody other than them), this wasn’t exactly scientific data.  It wasn’t like they lined up 300 death row prisoners, shot each one in the chest with a different brand of .45 and then watched the clock until they quit kicking.  Supposedly these were incidents from actual gun fights. 

 

And since gun fights by their nature are fluid, dynamic, and always suck, we can also assume that they’re going to be different.  To illustrate:

 

Shooting 1:  Subject is 105 pounds, soaking wet.  Pacifist.  Faints at the sight of his own blood.  His book club calls him “Todd.” Has never been in a violent encounter in his entire life.  Plays Barbara Streisand records to get “charged up”.  Gets shot in the abdomen with a Brand X .32.  Bullet lodges in the belly button.  Barely breaks skin.  Subject faints because of loud noise.  .32 Brand  X = 100% stopper.

 

Shooting 2:  Subject is 310 pounds of prison hardened muscle.  Has a spider web tattooed over his whole face, and his friends call him “Death Train”.  Subject 2 is high on coke, crack, meth, elephant tranquilizers, No-Doze, and Cherry Pepsi.  While robbing a bank during a tri-state killing spree, Subject 2 engages in a running gun fight with police and is shot through the lung with a Brand Y .45.  Subject 2 then carjacks a busload of handicapped nuns to escape.  Later has friend who flunked out of Vet School remove the bullet with a pair of barbeque tongs.  Subject 2 then goes to 50 Cent concert.   Brand Y .45 = 0% stopper.

 

So from this illustration, you are far better off carrying the Brand X .32 than the Brand Y .45. 

 

Now obviously, that is flawed, because of the nature of the subjects.  Death Train and Todd are not equivalent in any way.  Death Train would EAT Todd.  However, they’re both people that got shot in the torso with a single round, therefore they are valid M&S stats. 

 

Then you’ve got people shot in the heart vs. those shot in the gut.  Both bad, but one is usually fatal in a matter of seconds by the basic facts of biology.  However, both are one shot stops.  So if the guy carrying an inferior round, is a better shot, that round gets a better percentage. 

 

And then my personal favorite, they disregard multiple shots.  Because if you shoot the guy twice, then that doesn’t count.  I don’t know about you guys, but anybody worth shooting is worth shooting five to seven times.  I’m not going to shoot the guy once, and then wait around to see what percentile he falls into.  My gun is going to sound like a friggin’ jackhammer until he decides to leave me the hell alone.

 

Once again, before you jump onto any Gun World bandwagon, exercise a little critical thinking.

Pistol class on the 17th

I’m co-teaching a basic pistol class on May 17th out at Global 1 in Cedar Fort.  I’m doing the lecture portion, that will be spaced throughout the day, and that will cover everything needed for the Utah CCW permit.  (and a good refresher for everybody else).

The rest of the day will be a pistol class.  It will be a long day and we’re catering lunch.  The other instructors are extremely experienced, one longtime military SF instructor and one former Blackwater contractor and me (by FAR the least experienced, but I give a fun lecture). 

$150.  Contact me for details if you’re interested. 

On gun safety and getting your feelings hurt

There are 4 basic rules of gun safety.  If you always obey these 4 rules it makes shooting somebody on accident almost impossible.  To paraphrase:

1. Treat all guns as if they are loaded.

2. Keep your finger off the trigger until ready to fire.

3. Don’t point the muzzle at anything you don’t want to put a hole in.

4.  Know your target, what’s behind it, and what’s around it.

Pretty basic, pretty simple, and if you ingrain them and do them automatically and unconsciously then your odds of having a negligent discharge go way way way way down.

Now there are two reasons people violate these basic rules.  Ignorance or complacency.  Ignorance is when you’ve just not been taught.  You don’t know the basics, so you violate them.  Understandable, and that is why it is always the job of those of us who are educated to teach others whenever possible. 

Complacency is when you know better, but you get lazy, or stupid, and you break a rule anyway.  I handle guns for a living every day.  All it takes is for me to not pay attention for a second and I could kill myself or somebody else.  So any time you use a gun, you have to mentally shift gears.

Now we all screw up.  Everybody can fall victim to carelessness.  The key is that if you see somebody else doing something dumb, don’t be afraid to call them on it.

Now this is difficult as a gun dealer, because I get all sorts of people coming into my shop in various states of ignorance or carelessness.  Keep in mind I need to be nice to these folks in order to get their business, because if I can’t sell them guns, then I can’t pay the mortgage.  That’s how it works.

But I’m an instructor first, dealer second.  So if you come into my store, and do something careless with a gun, I’m going to have to correct you.  First off, this is for the other innocent bystanders in my shop that don’t deserve to have guns pointed at them.  Secondly, maybe I can help you ingrain some good habits so you don’t blow an extra hole in yourself sometime in the future.  I will try to be polite.  If I do something wrong, then one of my guys will correct me.  That’s the nature of life, and something that the gun culture absolutely has to do. 

When you screw up, and have it pointed out, just fix it.  The correct answer when you accidently sweep somebody with a muzzle is, “sorry about that” and then DON’T DO IT AGAIN. 

The wrong answer, the absolute worst possible answer, is “Don’t worry, it’s empty” or “I know what I’m doing.” Because if you tell me something like that, you’re a friggin’ moron.  And when I correct you again, I won’t be polite.  Your feelings come second to the safety of the people around me.  When somebody corrects your screw ups, be glad, and fix it.  Don’t get all huffy and offended.  Anybody can mess up, that doesn’t make you any less of a man.  (and I say man, because every single time I’ve seen somebody get their feelings hurt over a safety correction has been a dude) 

Yesterday I had a guy looking at a rifle.  He was holding it, and didn’t realize that there was a group of people off to his side.  He was covering them with the muzzle.  I was talking to another customer, but I was very polite, excused myself,  reached over, lightly touched the barrel, and steered it back in a safe direction.  I said “You’ve got somebody over there.  Watch where you point that.”

That was it.  Then I went back to the customer that I was originally helping.  The customer I corrected got all offended.  He told one of my Minions that “Well, I didn’t know it was LOADED.” (see rule #1) and then “I know what I’m doing, because I’m in the Army.”  Then he left.

Okay.  I didn’t set out to hurt this fellow’s feelings. Correcting a stray muzzle is an automatic response for me.  The fact that he took it as some sort of personal offense is too bad.  And I wish I would have had the chance to talk to him. 

Safety applies to everyone.  I don’t care if you’re in the Army.  Uncle Barbie was at the shop last night.  He spent 7 years as an NCO in the Airborne.  I asked him what he would have done if one of his soldiers had told him that gun safety rules didn’t apply because of superior Army training.  Barbie said that he would have clubbed his skull in.   Apparently the whole polite thing doesn’t really apply in the military.

I’ve personally been corrected.  If you handle a gun, it’s going to happen.  Period.  Don’t get all butt hurt.  Just deal with it.

Movie Review: Expelled, no intelligence allowed

http://www.imdb.com/title/tt1091617/

 

Yes, I am the kind of nerd that will go to see a documentary on its opening night, and in this case, I’m glad that I did.

 

I thoroughly enjoyed Expelled.  Many “conservative” documentaries are pretty badly done, dull, witless, and just preach to the choir.  (guilty of it myself) but Expelled is well done, paced well, extremely interesting, and actually entertaining. 

 

You’ve probably heard the critics harping on it, about how it is biased, unlike other successful documentaries like an Inconvenient Truth, because according to critics, it was the BEST THING EVAR! 

 

Yes, Expelled is biased.  Good.  Sometimes the underdog side needs to get a turn too. 

 

As somebody who has tangled with the self-righteous world of Academics (‘cause guns in school are baaaad), it was really interesting to see the parallels between this topic, and other topics that I’m more familiar with.  The MO stays the same.  They misstate what you believe in to make it absurd, then they throw up every barrier they can think of, including threats and bullying, fire you if they can get away with it, vilify you in the press, then sue you.  Now where have I seen that before?

 

The best part of Expelled was when Ben went to Germany to look at the dark underbelly of Darwinian thought.  The Eugenics movement.  That part was actually very moving.

 

The most entertaining bit was when Ben interviewed that prick, Richard Dawkins, and made him look like a complete buffoon.  Word to the wise, Dick, you shouldn’t have underestimated somebody who has like 75 more IQ points than you do.  You’re being interviewed by a man that wrote speeches for presidents and knows more trivia than anybody.  He made you look like a tool, Dick.  Go back on O’Reilly, you fared a lot better there. 

Sold out on Amazon, so that's all folks

I discontinued the MHI version on Infinity.  Amazon’s now out, BN is out.  You may still be able to get them for a few days on that other link on Amazon because that is direct from Infinity. (the used & new link for $17 something).  Then I’ve got 20 on the way to me.  So that’s it.

But at least it went out with a bang over there:

Amazon.com Sales Rank: #7,312 in Books (See Bestsellers in Books)

Popular in these categories: (What’s this?)

#51 in  Books > Science Fiction & Fantasy > Fantasy > Contemporary
#82 in  Books > Entertainment > Television > Shows > 1980’s

 

Still scratching my head on the 1980s part.
