Can you believe that? I'm shocked we win wars with rules of engagement so suicidal. :barf:
Anyway, back to the topic at hand. I'm more of a target guy (not so much self defense), but I don't think I would give a warning shot. Any bullet that comes out of my weapon is either intended to hit a target at a range or center mass of an attacker at home. What would I shoot at for the warning shot? Shooting in the air is dangerous. What if I hit an innocent person? I can't see anything good coming from a warning shot.
