Since I don't have kids and don't have to round them up/get to them, I kind of decided all I need to do was secure my perimeter, there are both regular phones and cell phones where we sleep, the perp walks through the door I have the advantage, I go looking for him, maybe 50-50 or worse if he gets a lucky shot off real fast, he might even see me first if I go looking, that gives him the advantage. I like the idea of someone walking through the door with me pointing at it myself. I'm not really trained to clear a house, if I am forced into it I will, if I'm not forced I'll sit tight and wait for them to come to me. Chances of me surviving are good if the come to me, their chances of survival are real bad.
