On a computer, I would just shoot them all and let God sort them out.
I hope that in real life I would be more discriminating. I carry every time I leave the house, I would not draw for any reason except that my or my wife's life was in immediate and deadly jeopardy. I ain't protecting Walmart's cash register, I ain't shooting at a bad guy holding a hostage, I won't try to tell who is the good or bad guy in another gun fight, and I won't shoot at somone stealing my car. (as long as I am not in it) I don't want to be a cop I just don't want to be a victim.
