Police kill armed teen student at Texas school

32. They teach that because firing at center of mass is the most effective way to STOP an attacker

Nobody teaches students to aim for the head, or to keep firing until the attacker is dead.

No credible training class in the world would teach their students how to "wing" someone or shoot them in the leg.

Correct, because trying to do that is likely to result in a missed shot and failure to STOP the attacker.

Another thing they teach you in self-defense classes is how to behave when the police arrive after you have used deadly force in self-defense - Generally keep your mouth shut, don't brag, don't say anything that could be inferred as intent to kill the attacker.

If you haven't taken a self-defense course, I recommend it. They can be real eye-openers.
