Don’t shoot unless you really need to.
If you need to, make it count.
Stop shooting once the attack has ended.
And God help you if your attacker is a nice-looking 17-year-old black wannabe thug.
IIRC, Bite-me's advice was to get a "double barreled shotgun and fire off a couple into the air..." or some such blather.
Well, if that advice were taken, were a real prowler toattack, the air-shooter would be empty. That is not good.
