>> there are cases where it is fairly simple to tell if you are in front of a disabled or mentally ill person then a nutcase high on crystal meth
What are you trying to say here? It's OK to kill unarmed drug users, but not unarmed crazy people?
I don't think it is OK in either case and I'm putting my money where my mouth is. I live in the tenderloin and walk everywhere, so I get approached by aggressive people who are acting weird and scary everyday. So far I have never even considered shooting them.
