Not my own? I don't know, because it's none of my business, and neither do my neighbors, because it's none of theirs. I really haven't had occasion to discuss it with any of them, and it would probably be a long while before it got to how well armed the neighborhood really is just because of me, and then only with ones I was confident wouldn't spill the beans. That confidence would not come easily. Because of people like me, don't place too much confidence in surveys of gun ownership.
The one on my person is in my back pocket - not on my person is about 10' - there's 1 in every room of my house so its about 10' from anywhere in my home. Too much or not enough?
