Embrace the suckiness ...

Of your pistol's terminal ballistics, and vow to keep fighting until you win. From LawOfficer.com's Officer Down series:
Soulis had planned to shoot through the back window if Palmer drew a weapon, but for reasons he still doesn't fully understand, he moved forward and to his right, stopping alongside the passenger door, not more than two feet from the window. Instantly, he realized he'd made a grievous blunder. Grinning with blood lust, Palmer lunged across the seat and shoved a Smith & Wesson Sigma up into firing position. Before Soulis could react, the S&W barked flame, driving a 9mm solidly into the center of his chest. The impact knocked Soulis back slightly, but his vest stopped the bullet.

Palmer was out of the Toyota a split-second later, firing the gun at him over the roof. There was no other cover nearby, so Soulis went down onto one knee behind the front fender to put the Toyota between them. But, at the same instant, two rounds crashed through his left arm, one just above the wrist and the other dead center on the forearm. Another struck him in the left thigh, although he wouldn't become aware of it until later.

Soulis was shooting back now, pumping rounds through the windshield into his assailant. Palmer went down immediately, and Soulis used the opportunity to seek better cover. The only decent cover nearby was his patrol car, so he started backpedaling in that direction, Glock at the ready and eyes scanning for Palmer's return as he moved. Then, spotting the cruiser out of the corner of one eye, he turned and started to sprint toward it. He had barely completed the turn when Palmer opened fire again. One round missed, but another tore through his left shoulder and exited his left bicep. He kept moving until he reached the back of the car, where he dropped to one knee and got back into the fight.

Palmer was scurrying back and forth down the driver's side of the Toyota, shrieking with rage and stopping sporadically to fire, but Soulis was more patient. He held his fire, waited for Palmer's head to pop into view, and then took a shot each time it appeared. Although Soulis knew he was getting hits, Palmer seemed impervious to his gunfire.

Soulis was also becoming apprehensive about his wounds. The bullet hole in his left wrist was an ugly, swollen mess that made him wonder if he would have enough dexterity to reload, and the one in his thigh was spewing blood all over the back of his cruiser. Believing his femoral artery had been hit, he pressed his left hand down over the wound, but that only caused the blood to shoot out another, previously unseen bullet hole. He feared he would bleed out before he could stop Palmer.
...
With these thoughts came an unexpected calm, followed by a new resolve. Up to this point, he'd been fighting a commendable, though primarily defensive battle. But now, infused with the realization that Palmer had to be stopped and that only he could do it, he went on the offensive. Now the predator, he resolved that Palmer would never leave the parking lot, even if he had to take more hits to stop him.

Soulis' gun wasn't empty yet, but he knew better than to take the offensive without reloading. As he ejected the partially empty magazine and slapped in a fresh one, he saw something he hadn't expected. Apparently, Palmer had seen the ejected magazine hit the ground and assumed Soulis had either collapsed or run out of ammo. He left the cover of the Toyota, and advanced toward Soulis. Unaware that he was approaching a conscious and fully armed police officer who knew how to capitalize on an opportunity like this, Palmer walked toward the cruiser. Soulis waited patiently, tracking the man's approach by watching his feet under the cruiser.

Palmer hesitated when he reached the cruiser's right-front fender, as if to consider moving over to the driver's side. Soulis knew he'd have trouble tracking Palmer if he came around that way, so he decided to make his move without delay. He lunged out from behind the car, thrust the Glock up into firing position, and opened fire. His first two rounds hit Palmer center chest, rocking him back on his heels. Palmer flinched as two more rounds hit center mass, and then started backpedaling toward the Toyota. He was still holding his gun, but never raised it to fire.
...
Soulis stopped and fired two rounds through the back window. The first missed, but the second hit Palmer in the upper back, driving his head forward into the steering wheel. That seemed to have done the trick, but then Palmer sat up again, dropped the transmission into reverse, and started backing up. With no time to ponder how Palmer had absorbed so many hits, Soulis took aim and emptied the magazine into his assailant.
...
Remarkably, Palmer had taken 22 hits from Soulis' .40-caliber Glock, 17 of which had hit center mass. Despite the fact that the weapon had been loaded with Ranger SXTs—considered by many to be one of the best man-stoppers available—Palmer lived for more than four minutes after the last shot was fired. His autopsy revealed nothing more than a small amount of alcohol in his bloodstream. Although Soulis could not have known it, Palmer was wanted for murder in a neighboring state. [emphasis added]

[Officer] Soulis made a full recovery and returned to work less than a month later. ...

Article here. While the article is written from an officer-safety standpoint, the key lesson is that a determined attacker can be very difficult to stop. Expect even well-aimed shots to not immediately stop a determined attacker. Only shots that disrupt the central nervous system can be counted on to immediately disable an attacker. Otherwise, you're just punching holes in a fluid-filled body, and hoping your bullet either causes sufficient skeletal damage and/or punctures major blood vessels and your attacker bleeds out to the point where he cannot continue his deadly attack. And that can take a while. (Obviously, if the attacker stops his attack by, e.g., giving up, running away, etc., and is no longer an immediate and/or continuing deadly threat to you and your loved ones, deadly force is no longer justified).

Prepare yourself mentally so that you aren't surprised, and keep fighting. And prepare for the very real possibility that you yourself might be shot, and vow to keep fighting, and to win.

Consider the amount of ammo you carry. Will it be enough if you have to fight for your life against an attacker like the one in the story above?

The failure of ballistics databases

Short article on the failure of gun ballistics databases:
Seven years ago, New York started a database of "ballistic fingerprints" for all new handguns sold in the state. The bill's backers sold it as a crime-solving device, arguing that the state would now have a sample of a spent shell and bullet for every new gun sold. This, they said, would help police connect future evidence from crime scenes to specific guns.

Since then, the authorities have entered 200,000 newly purchased guns into the database and spent $1 million dollars a year on the system. Yet it hasn't led to a single solved crime. The only other state with such a database, Maryland, can attribute at least one conviction to the system since it was created in 2000-more than zero, but few enough that the state's own Police Forensics Division has suggested scrapping the program because of its demonstrated lack of benefits.

This hasn't come as a surprise to gun rights activists, who pointed to several potential problems when the databases were originally debated. Among them: The markings left by a gun are not guaranteed to be the same over the long term and can be deliberately changed with simple expedients such as filing inside the barrel; the vast majority of guns used in crimes are stolen or otherwise obtained in a black market, not used by their original legal owner; devoting so much record keeping to every gun sold guarantees wasted effort, since less than 1 percent of all guns sold will ever be used in a crime.

Article here. Apart from the almost complete failure of the existing databases in helping solve crimes, the other, more pernicious attribute of such databases is that they create a de facto gun registration scheme. And as history has shown us time and again, gun registration is often the first step towards gun confiscation. Indeed, registration is a necessary first step. And governments have murdered hundreds of millions of their own disarmed citizens within just the last century. Such atrocities are far more likely against an unarmed populace than an armed one.

Just what's up there, anyway?

From the Palm Beach Post:
RIVIERA BEACH — A day after he was hit by a stray bullet in the back of the head, 74-year-old E.T. Strickland was back at work today - with the slug still stuck in his skull.

"I am the luckiest guy in the world," Strickland said from his business, Sunrise Financial Corp. in Palm Beach Gardens. "An inch more to the front and it would have hit me straight on. As it is, it just glanced around and lodged in the back."

The bullet hurts, he says, but not enough to stop him from going back to work.

"We sell commercial real estate so it's got to go on," Strickland said. "I didn't know what else to do and I felt pretty good."

Strickland and his wife, Pam, were driving home to Singer Island from a belated birthday dinner at Taboo in Palm Beach on Tuesday night when he was hit by a bullet from an attempted armed robbery outside the Walgreens near Broadway and Blue Heron Boulevard.

"The instant it hit me, I felt like somebody had hit me with a baseball bat," he said. "I saw the hole in the window and the blood. I pulled over so I could bleed outside the car."
...
Meanwhile, he says he's not going anywhere even though his home has been broken into twice, his car was once stolen on Singer and his wife's car was broken into on mainland Riviera Beach.

"It would be unlikely that a fifth thing would happen," Strickland said, "but then again, that is what I said about the fourth thing."

Handgun "knockdown" power

From PoliceOne.com:
The FBI report also emphasizes that unless the bullet destroys or damages the central nervous system (i.e., brain or upper spinal cord), incapacitation of the subject can take a long time, seemingly longer if one is engaged in a firefight.

Failing a hit to the central nervous system, massive bleeding from holes in the heart or major blood vessels of the torso, causing circulatory collapse is the only other way to force incapacitation upon an adversary, and this takes time. For example, there is sufficient oxygen within the brain to support full, voluntary action for 10-15 seconds after the heart has been destroyed. (3)

More often than not, an officer firing at a suspect will not immediately know if he or she has even struck the target. The physics are such that the body will rarely involuntarily move or jerk, and usually there is no noticeable spewing of blood or surface tearing of tissue. Often there is no blood whatsoever. (4) That is why military surgeons and emergency room physicians take great time and pains to carefully examine gunshot victims for any additional small holes. Often that is the only indication the person has been shot.
...
In the mid-1980s I was involved in my first shooting as a police officer. But to give the story context, I must go back to 1982 when I graduated from the Long Beach Police Academy. The first thing I was told by experienced training officers I trusted and looked up to, was to “get rid of that pea-shooter 38 they issued you and buy a real gun with some knockdown power!” Although we were issued .38 caliber revolvers, we were authorized to carry a number of different caliber weapons on duty, the largest of which was the 45 Long Colt.

Imagine my surprise when I was confronted by a suspect armed with a shotgun in a dark alley and my Long Colt didn’t live up to its billing. I fired five rounds at the suspect. It wasn’t until I fired my last shot — intentionally aimed at his head — that he went down. I can’t begin to relate to you the surprise and horror I felt when there was absolutely no outward indication I was hitting my target. It was the kind of situation cops have nightmares about.

What actually happened? I fired five rounds at a distance of about twelve feet. The first one missed completely. The second struck his upper leg and broke his femur. The third struck him in the shoulder/chest. The fourth round hit him dead center—in the heart. And of course, the fifth was a headshot. Three of the five rounds created fatal wounds, though only one had immediate results.

Needless to say, I was pretty shaken by the whole thing. Not by the morality of what I’d done; the suspect had already fired at a bystander and taken a hostage earlier. He was also high on PCP. That wasn’t my inner struggle. What shook me was how unprepared I felt; how totally off guard I was taken by what occurred. No one ever told me it would be like that. The reality was contrary to everything I thought I knew about deadly force.

Seven year old database hasn't solved a single crime

From the Washington Post, on New York State's seven year old ballistics database:
ALBANY, N.Y. -- New York's seven-year-old database of handgun "fingerprints" has yet to lead to a criminal prosecution, and questions linger about its effectiveness. Still, state police remain committed to the tool, saying that more time and a long-awaited link to a federal ballistics database could bring success.

Since March 2001, identifying information about more than 200,000 new revolvers and semiautomatic pistols sold in New York have been entered into the Combined Ballistic Identification System database maintained by state police. New York and Maryland are the only states that maintain statewide databases.

Article here. The article says that operating the database costs a million bucks a year. What an enormous waste of money.
