Well, maybe I don't. However, I'm having trouble relating the things you're saying to something that is more likely to happen at, say, room's length. What do you suppose is a typical self-defense shooting distance for a non-law enforcement individual? There's still the shoot-no shoot question the individual has to overcome. Not just whether the target is a justifiable threat but also the great leap of actually shooting another person. But I suppose you could say that's entirely mental.
You have a military background. Do you think the police have any differences in their approaches to what you're saying?
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
