> everything happens in the margins

including accidentally shooting yourself, accidentally shooting the wrong person, getting shot by someone else who misread who was the good guy with the gun and the bad guy with the gun, and turning it on yourself when the pressure of it all gets to be too much.

I don't think anyone in this thread disagrees with you on this.

Keep in mind that your point is orthogonal to the topic of whether you should have a round in the barrel or not. Everything you say here applies to both cases. (Well, OK, there's a tiny marginally higher chance of accidentally shooting yourself).
