I'm new to CCW, about few months away from my CHL class and few more months before getting my CHL permit....So I have a question for you, guys...Let's say someone will try to take mine or my family and friends life(either by gun, knife ...) and I'd have to shoot that person to survive, does it matter if I just shoot him once vs. unloading my whole mag??..Wouldn't that be considered "unnecessary" or "overkill"(not that it would matter to me!)...Is there any difference between killing somebody in self defense at home or in public??..Thanks for sharing your knowledge and experience with this matter!
