Oh, I am quite sure you know better Deadman, but there were others talking about "home defense" by means of empty gun and glorious acting.
In my book a very dangerous game, even hiding beneath the bed seems a better choice.
I have given the subject some thought since I have a number of rather scary looking (and very much not loaded) guns adorning my walls.
But, I'll stick with the axe. Its scary enough, and real enough.
