Where I tackle a sacred cow

Stopping power is a myth. There, I said it. Every time there is a shooting, some yahoo comes forward to talk about how this gun or that one would be better because stopping power…

It’s bullshit. There are only four ways to stop a determined attacker:

  • A catastrophic hit to the brain or spinal cord (CNS)
  • Lower his blood pressure to the point where his brain is incapable of operating
  • A ‘mission kill’ where his body is so damaged that it can’t continue the attack (for example: damage his pelvic girdle so an attacker armed with a melee weapon can’t close the distance)
  • Convince him that he is out of the fight

Hitting the brain or spinal cord will usually end an attack. A hit to the head that misses the brain will not work. I can think of seeing at least three shootings from my years as a street medic where a bullet hit a person in the head, but didn’t penetrate into the brain. One of them was a suicide attempt. A good example of a head hit NOT taking someone out of the fight is Navy SEAL Matt Axelson. He took a bullet to the head that left his brain matter exposed, yet continued the fight.

Punch enough holes in someone’s vasculature, and they will lose blood pressure to the point where the brain is no longer being supplied with oxygen, and the person is rendered unconscious. Even a lucky shot with a small caliber like a .32 is capable of doing this- say if it hits the aortic arch and causes a transection. Sometimes it takes several hits. I have seen people take multiple hits to the torso from a .223 and stay in the fight.

A mission kill is where you damage a person’s body severely enough that they physically can’t continue the fight. Say, a hit to the pelvic girdle preventing someone from chasing you down. An excellent example of this was Kyle Rittenhouse shooting Gaige Grosskreutz in the arm. The hit not only rendered that arm as incapable of firing shots, but also made it impossible for that arm to release the handgun it was holding.

Then there is simply convincing someone that they are done. This is a well documented phenomenon where a person will be shot, and the wound is far from incapacitating, but the person simply lies down and is out of the fight.

There are people out there, however that still insist in the magical properties of this caliber or that bullet. Bullets are simple tools. They are a tool that delivers the chemical energy stored in the gunpowder to the target in the form of kinetic energy. The force with which a bullet hits the target is equal to the force that’s directed back into the shooter. It’s one of Newton’s laws- every action has an equal and opposite reaction. Any bullet that has enough power to “knock down” the target will do the same to the shooter. It is at this point that many will point to Marshall and Sanow’s work, and I will admit that I was a follower and believer in this study when it first came out.

The Marshall and Sanow “study” was fatally and egregiously flawed. The most basic flaw was “selection bias” in that the study excluded any shooting where it took more than one shot to halt the attack. So if I have a situation where I shoot someone and he doesn’t go down, so I shoot him three more times before he does, that shooting would be excluded from the study, even though that shooting demonstrated a complete failure to stop the attack.

What a bullet does is simple: the chemical energy in the gunpowder is converted to kinetic energy that is transferred to the bullet. That energy is then transferred to whatever that bullet strikes. If the object struck is a person, then physiology takes over from physics there. The damage done is dictated by how much energy was transferred to the targeted person, and what body parts of that person where targeted.

So there are a couple of things that are important in stopping an attack: the amount of energy transferred, and what part of the body that it is transferred to. Suffice it to say, you want a bullet to have enough energy to damage the body system that it strikes, and that means you want it to penetrate far enough to transfer that energy into something physiologically important. You don’t want a bullet bouncing off of the grizzly’s skull or getting stuck in a denim jacket. It does not do any good if that happens. You also don’t want that bullet to over penetrate. What ever energy that bullet has left after passing through the target is useless in stopping the target from doing things that you don’t want them doing.

You also want to work on shot placement. Hitting a right handed shooter in the left arm isn’t going to do you a bit of good.

Buy yourself a gun that you can shoot well, then spend time practicing. Load it with some high quality defensive ammunition, make sure the firearm functions well with that ammo, then practice.

Why? Because you want to keep shooting until the attack is over. That means if you have to shoot him to slide lock to stop the attack, then shoot him to slide lock. Make sure that you can hit a person-sized target 100% of the time at 10 yards, rapid fire WHILE UNDER STRESS. Make sure that you can hit a person sized target 80 percent of the time at 20 yards while under stress. Sounds easy, but studies show that shooting to this level is rare while experiencing the stress of an actual gunfight.

If you do carry a handgun, use a .38/9mm or larger if you can. If you can’t carry something that large, carrying any firearm is better than not carrying one at all.

Put good quality defensive ammo in it. Don’t worry about finding the perfect latest and greatest ammo, but do get something that is modern as well as being accurate and reliable with your chosen firearm.

Practice. A lot. At least 100 rounds per quarter at a minimum. Shooting is a perishable skill. The more you do it, the better you get at it.

To all of you 10mm or .45ACP fans: If you really believe in stopping power, then provide the physics or physiological basis for stopping power. How does it work, what causes it, why do you think your caliber is different from all of the others?

Dispersal of Forces

Now that there is a Red Flag law that will soon be signed by Biden, there are some realities that must be faced. Think about what the left has been doing and saying for the past two years: anyone who disagrees with Fauci is crazy, anyone who argues with a leftist is a fascist, and other arguments intended to make you an unperson. How easy has it been to get banned from social media? That same moron that complained about the meme you posted on Facebook now has the ability to send an armed SWAT team to your house to have you killed. SWATting on steroids.

Of course Red Flag laws will be abused. Divorce attorneys salivating at this idea.

Those attempts at destroying your First Amendment rights will soon be applied to your Second Amendment rights. The Disinformation Bureau will soon have a counterpart for guns, bet on it. The agents of the ATF have a collective boner at the thought of new budget money. Government informants will soon get rewards for turning you in.

I have experienced this first hand. A couple of years ago, I was made into a prohibited person, thanks to an ex-girlfriend who used allegations of domestic violence to get a domestic violence injunction from a court. It took me weeks to clear my name, thousands in legal fees, and was a real inconvenience.

The first hint that you have of this is there will be a knock at the door, and you will open it to find the cops standing there with a court order to take your guns. Now in my case, they were stupid. I handed them a couple of token firearms and the left without searching. I don’t expect cops in these future red flag cases to be so casual. So here is my suggestion:

The military has had a policy of “dispersal of forces” ever since nuclear weapons became a thing. The idea is not to put all of your forces in one spot, thereby ensuring that all of your weapons won’t get caught up in one giant fireball. We can do the same thing.

  • Make sure that you cache some of your weapons and ammo in locations away from your property. Don’t put all of your eggs in one basket.
  • Bury some in the backyard. You do have some 6 inch CPVC, don’t you?
  • Have others at a trusted friend’s house.
  • If you get a visit from the confiscation police, don’t immediately go retrieve your cache. They will likely return, looking for you to do exactly that.
  • Best if those cached weapons are “ghost guns” or guns bought on the secondary market, so there is no record of you having them.

Be paranoid, because as we have explained here on this very website, someone IS out to get you. If you DO get raided, get the word out. Make sure others know that they are taking guns. Maybe you can keep it from happening to someone else.

Gaston Update

As regular readers know, I recently completed project Gaston– an 80 percent Glock compatible pistol frame. Today was the day that I finally got to take it out to turn some money into noise.

I got to put a single magazine through it. Accuracy was fine. Here is the target from 10 yards, rapid fire.

The problem was reliability. Out of 16 rounds, there was one stove pipe, three failures to feed, one round with a dented primer but no PEW!, and one where the fire control group didn’t reset.

I didn’t even get a chance to troubleshoot before the RSO came over and forced me to stop shooting because my ammo was steel cased.

I am wondering if the problems were caused by too heavy of a recoil spring. The slide is a lightweight one, and perhaps changing out the standard 15 pound spring with a 13 pound one will work.

In the meantime, I need to buy some brass cased ammo and save the steel cased stuff for the outdoor range. More on this later.

Staples

I recently became aware of a Supreme Court case from 1994, Staples v. United States. This case involved a man who had been arrested for having an AR-15 with more than a few components of an M-16 fire control group installed inside of it including the selector, hammer, disconnector, and trigger.

Suspecting that the AR-15 had been modified to be capable of fully automatic fire, BATF agents seized the weapon. The defendant was indicted for unlawful possession of an unregistered machinegun in violation of the NFA.

At trial, BATF agents testified that when the AR-15 was tested, it fired more than one shot with a single pull of the trigger. It was undisputed that the weapon was not registered as required by the NFA. The defendant testified that the rifle had never fired automatically when it was in his possession. He insisted that the AR-15 had operated only semiautomatically, and even then often requiring manual ejection of the spent casing and chambering of the next round. According to the defendant, his alleged ignorance of any automatic firing capability should have shielded him from criminal liability for his failure to register the weapon.

The trial court disagreed, and the man was convicted and sentenced to five years’ probation and a $5,000 fine. He appealed the conviction, and the appeals court agreed with the trial court, affirming his conviction. It was appealed and wound up at the SCOTUS level. Justice Thomas wrote the majority opinion, and let me tell you, there are some great quotes in that opinion.

The opnion says that the language of the statute provides little in the way of guidance in this case. The NFA is silent concerning the mens rea (intent) required for a violation. It states simply that “[i]t shall be unlawful for any person . . . to receive or possess a firearm which is not registered to him in the National Firearms Registration and Transfer Record.”

Nevertheless, silence on this point by itself does not necessarily suggest that Congress intended to dispense with a conventional mens rea element, which would require that the defendant know the facts that make his conduct illegal.

Staples v. United States, 1984

The Government argued in that case that Congress intended the NFA to regulate and restrict the circulation of dangerous weapons. Consequently, in the ATF’s view, this case fits in a line of precedent termed “public welfare” or “regulatory” offenses, in which SCOTUS understood that Congress sought to impose a form of strict criminal liability through statutes that do not require the defendant to know his conduct was illegal.

One money quote that I saw was this one:

The Government does not dispute the contention that virtually any semiautomatic weapon may be converted, either by internal modification or, in some cases, simply by wear and tear, into a machinegun within the meaning of the Act. 

Give the case a read, and see what you can find.

You’re doing it wrong

A city worker was injured after being struck by debris from a blank that had been fired during active shooter simulation training. Did we learn nothing from the Alec Baldwin disaster? Even with blanks, projectiles still leave the barrel, and using real firearms to fire blanks is just asking for live ammo to work its way into the training scenario. All it takes is one forgotten spare magazine in an officer’s pouch, and tragedy results.

When engaging in gunfire simulation, there are a few rules, the first of which is that you don’t use real firearms. There are plenty of alternatives. From high realism/low danger like simunition, to Airsoft, paintballs, blue guns, or even simply fireworks.

There is no need EVER for pointing real firearms capable of firing actual bullets at people in a training situation. You have set yourself up for a scenario where a single point of failure is all that stands between safety and serious injury.

Look at this picture from another version of the story and tell me what this is accomplishing:

Slide lock, magazine inserted, in holster? Don’t get me started on the flimsy belt or the bunch of fabric that can get caught in the safetyless Glock trigger.

Safety and Guns

Watch this video. 28 seconds into the video, look closely at the right side of the frame.

How close was that guy to the line of fire from the shots taken at 19 seconds? This makes my heart beat faster just watching it.

If the guy who was down there had been shot, who would have been at fault?

  • The designer of the stage who designed a stage where the ENTIRE stage wasn’t visible to the RSO
  • The RSO who didn’t make sure the down range area was clear before calling “hot range”
  • The shooter for taking the shot without verifying what was behind his target
  • The guy who was downrange for being where he was
  • The bystanders who didn’t keep an eye out and speak up

My answer? All of the above. We as shooters are ALL collectively responsible when things like this happened. There is a lesson to be learned from every incident. If we are unwilling to look at it with an honest eye towards safety, things like this will happen more often.

Safety isn’t just the responsibility of the RSO. Nor the shooter. It is everyone’s responsibility.

Design the environment so the RSO can see the entire shooting area. As the RSO, make sure that you are aware of the environment. The shooter needs to follow the four rules. The bystanders should keep an eye out for each other to make sure that every one of those who go down range to paste targets come back.

I have supervised people in all sorts of environments. SCUBA Diving, firefighting, HAZMAT, all sorts of things. Safety incidents are rarely the result of one thing that went wrong. It is often the result of a list of minor things that each went wrong. Each of us is responsible for what happens.

Like many shooters, I have had an ND myself. Two, in fact. I was much younger, and not as experienced as now. The first happened when I was 20 years old. I was at the range and pulled the trigger on my S&W 4506. I pulled the trigger, and nothing happened. I pointed the gun at a 45 degree angle, sort of down range, and sort of in the air. I pulled the trigger again. I was surprised when it went bang the second time. Luckily, the weapon wasn’t pointed at anyone.

The second was entirely my fault. I was doing dry fire practice. After being done with that, I reloaded the pistol. For some reason, I forgot what I had done, dry fired again, and blew a hole in the front of my dresser. Again, at least I wasn’t pointing it at a person. A violation of Rules 1 and 2.

Both of those incidents were more than 30 years ago. I have never forgotten them.

Child, felon, killer

News in the Orlando area about two kids, ages 14 and 12, who committed a burglary, stole some guns, then engaged in a shootout with responding police. The two kids ran away from a local foster home, the Florida United Methodist Children’s Home. The home has a history of trouble, with the police responding there as many as 200 times a year. In March, one of the foster kids residing there beat and murdered one of the home’s security guards.

The pair used a shovel, a crowbar and large rocks to break windows to break into the home, where they then used baseball bats to destroy furniture, toilets and a tub. They soon located the homeowner’s guns — an AK-47, a pump shotgun, and a handgun, along with 200 rounds of ammunition.

The older one, a girl, was recorded saying, “I’m gonna roll this down like GTA.” They fired on police for over 90 minutes while police tried to negotiate. Police finally returned fire, striking the girl in the chest. Video of parts of the shootout can be found here as well as here.

The 14 year old girl has been arrested for stealing puppies in 2018 and for setting several fires when she was at another facility in Flagler County. The 12 year old boy has been in foster care since 2016 and just a month ago threatened “to kill a student and spread his guts all over the bleachers” while at school.

Both of them now face felony charges of attempted first-degree murder of law enforcement officers and armed burglary. Sheriff Mike Chitwood has this to say about the juvenile justice system:

“The brainiacs in Tallahassee, they want to do this restorative justice stuff. They need to take a deep look and say, ‘Something’s not right here,’ because where the rubber meets the road, these kids are killers. They’re capable of killing. This juvenile citation (expletive) that you hear from these faith groups, they need to worry about what’s going on in the pulpit in their church, not worried about what’s going on on the (expletive) streets when you have 14-year-olds and 12-year-olds arming themselves,” Chitwood said.

I have layers of security. Cameras. Alarm system. Gun safe. All of it is designed to prevent amateur attempts and slow down more professional attempts. Please secure your weapons in a safe. Even a cheap gun safe would have prevented the teens from accessing the weapons, and one can be had for less than $150. If long guns won’t fit in a small safe, remove the bolts from the long guns and lock THEM in the safe.

Blogshoot

This post is a plug for the upcoming blogshoot that is coming up this Saturday. I am going to do a “first aid for the shooting range” quicky class.

Be there. We had a good time at the last one.

This is the only post for today because I am doing some training for the maintenance of my medical license. Gotta get that done.
