I talk a lot about lethal force, and one concept comes up almost universally. I call this idea the leg shot syndrome. The leg shot syndrome is expressed by the statement I wouldnt aim to kill; I would shoot the robber in the leg. I believe I know where this thought comes from. It comes from the fact that everyone I give firearms classes to comprise the good guys. Good guys dont go around killing, robbing, and raping people. They believe that everyone has redeeming qualities. Good guys dont want to kill people, they didnt start the encounter, and if they had their way, the bad guy would just leave. Now before I get tons of hate mail, let me say that I understand the reason people think this, and I wish everyone in the world felt that way. If there were no bad guys, there would be no crime. I could then put more energy into my primary job of preparing for natural disasters instead of diverting energy to preparing for criminal disasters.
While understanding and admiring this idea, I want to emphasize that this is not a good way to apply this concept. There are many reasons why this philosophy is not sound in the lethal force arena. Some of these reasons are legal, some tactical, and some, yes, are even moral.
I will jump into what I hear as the most widely use reason why the leg shot syndrome should not be used, legal. A handgun is a lethal weapon. Unlike a baseball bat, a butcher knife, or a policemans baton, there is no less lethal way to use a handgun against another human. The law does not distinguish the difference between shooting a person in the head, and shooting a person in the chest. If there is not legally defensible motive and the person dies it is still murder. A bullet cannot be recalled once it leaves the barrel, and what it does upon entering a person cannot be decided by the person who fired the bullet. There is a major artery in the human leg, which if severed, can kill a person as quickly as shooting them in the chest.
Tactically manipulating a firearm under lethal force pressure is extremely hard. Quite a few books, and statistics from a vast amount historical data show that only about 1/3 of the rounds fired impact on the target. This doesnt seem to be that bad, until you look at other statistics that show approximately 90% of gun fights happen under 7 yards and comprise less than 3 shots total.
How realistic is it then that when most people would be lucky to hit their attacker, you are going to hit one of the smallest areas, and an area that is most likely to be moving. Tennessee (and every other state I have found that has a defined handgun training curriculum) specifies shooting center-mass with the intent to stop. This involves two concepts. The first being center-mass, this means aiming your projectile to impact inside the largest target area (the chest), since this is the largest area you have the greatest ability to actually hit it. Also the chest area has the largest ability to stop your attacker due to it being the location of most the bodys organs. Intent to stop, is neither aiming to kill, nor shooting to wound, either of these are irrelevant, your legal self-defense ability is centered upon the attacker being able to kill you, and trying to kill you.
If the mere presence of your legally owned firearm cause the attacker to stop, it has done its job, if one well placed round to center mass persuades the criminal to stop, thats okay, however if it takes 3 boxes of bullets to stop a drug crazed, gang-banging, neo-nazi terrorist from killing you, hey so be it. This intent to stop is the half of my moral argument.
The other reason comes from plain street sense. I have a few years working in corrections. These years are split between entry level corrections working on the recreation yards and cages listening to inmates talk about themselves and their crimes, to working as a supervisor in maximum security units and applying inmate psychological knowledge to keeping the prison running smoothly. Criminals do what they do because it works for them. If a mugger or a rapist tries to talk you into leaving with him, its because it has always worked for him before.
Believe me, a violent criminal hasnt decided to start being a violent criminal just because your there, a criminal starts small and works up gradually becoming more violent. If a criminal gets away with hurting you, he will do it to someone else. I am not saying that vigilante justice is okay, Im not. I am not advocating deadly force as a punishment for a criminal either. What I am saying is that you are a reasonable person, with an inalienable right to life and liberty, minding your own business, living a peaceful life. You have a right do what you need to do to be safe, to go home to your family, this criminal attacked you, tried to hurt you for no reason other than his personal gain, youre not trying to kill him, only making him stop trying to kill you. This is not wrong. This is right, your family needs you; make sure you do what needs to be done to be there for them.
