As a side note, there is a bit of available light from night lights in the hallway outside of the master bedroom. I would need to gather the kids, and then return to the master bedroom and simply plan to hunker down and defend that position until the police arrived. My thinking is that I would use ambient light to watch for any threat that might come up the stairs, and then I would try to identify and deal with the threat at the farthest distance possible (approximately 20 feet to the end of the hallway). I would be interested to hear if anyone can poke some holes in my theory, or if it sounds pretty reasonable. I didn't give home defense enough thought for too many years. Having kids and considering all of the breakins and other stuff in the news lately, I have been thinking about it a lot more over the last few years. I feel like I'm trying to play catch up now, and it leaves me feeling a bit on edge.
