I am from a very small community of around 800 people, although I now live in the city. I got to thinking about what my reaction might be, or how slow, or actually non existent if I may have had to draw on someone who was a long time acquaintance or even a friend. I cringe to imagine having to even fire on a bad guy I have never met here in the city. But hell, what if i went to high school with this person or something? For me, I think it could be a situation where I couldnt bring myself to fire on someone like that. Maybe only if it were me threatened by a major weapon or a firearm. Im not presenting any specific hypothetical, just a general thought on the situation.
I read a thread earlier where a guy had to shoot another through a door while he was attempting to break and enter. They were former acquaintances.
