i was talking with some buddies tonight and we got on the subject of personal home defense. how if you shoot someone youre going to jail and you can only use as much force as necessary. so someone said what about shotgun shells with salt in them, and i said, what about airsoft bb's instead. load it so it doesnt come out too fast, 800 fps or so. would be none lethal, or atleast i think it would be. the only thing i could see is the plastic bb's melting while fired. anyone ever thought of doing anything like this?
