Doesn't matter if it is a weak gun or a high-power air rifle, you don't know what it could be. In a badly lit area, which of these would you think is real?
My daisy powerline is advertised at 1000fps. It looks like a real rifle and some of my friends got scared when they came to my apt. and saw it trigger-locked in my closet. I don't have any doubt that a shot through the eye just might kill a person.
I'm drawing, regardless. Don't be a pr1ck and point a gun at someone and not expect to possibly get dead whether you're a "kid" or not.
