ya, watching you kill someone might be traumatic, for the kid. so would watching his dad stand there like an impotent ***** while there property is stolen, their lives threatened, maybe the wife assulted.
I really don't understand the idea that you should be dependant on others for your personal protection. all moral issues aside it's just damned inefficent. cops wont always be there when you are being victimized, but you're there, doesn't it make more sense to have the protection at the scene of the crime as it's taking place, instead of strapped to the guy who shows up to take the report later. (this is not meant as a slam on cops, just that in most cases the victim has no way to call them until the danger has passed)
