In one of my classes one of the participants expressed that in an altercation you shoot until the guy is dead. I jumped all over him, the instructor really didn't say much. I was upset that the guy wasn't thrown out of the class. There's a lot of trash out there.This was not a gun store, but a Conceal Carry Class, a few years ago. We had one guy, that kept pointing his pistol at the instructor, to the point he told him the next time, he was kicked out without a refund! I was kinda hoping this idiot didn't qualify for this permit, the kind of jerk that gives all gun owners a bad name! and a real danger to himself, and others!
