Technically, Kimber84, you're right. Hunkering down and waiting: (1) is a tactically sound move; and (2) is a legally sound move. Those of us with children, though, may not have that option. If something happens at my residence, for example, I may have to leave my room to get my daughter.
It takes a very brave man to see a shotgun and run after it to grab it wouldn't you say?
