I was once asked by a lady visiting if I had a gun in the house? I said I did. She said, "Well I certainly hope it isn't loaded!" To which I said, "Of course it is loaded; it can't work without bullets!" She then asked, "Are you that afraid of someone evil coming into your house?" My reply was, "No, not at all. I am not afraid of the house catching fire either, but I have fire extinguishers around, and they are all loaded too."
Good one ! :)
The one thing I think will happen in this arena is limiting ammo instead of trying to take guns. They have already run the cost up.
No ammo, you have a metal club, or rock. One good thing about black powder guns, easy to get necessary materials.
