Great assessment! And the Nairobi incident is a good example. But statistically, that is very unlikely to happen in the US. Nonetheless, I am right there too; carrying this 19 and a spare mag with me EVERYWHERE I go; all day; all night; and while I sleep it is near by. If you want to know the truth, it's a pain in the ass. Too bad I know it's a damn necessity.
But I also make sure that my instant alarm is set when I am about to go to bed, and I avoid places where statistically I am more likely to encounter a predator, like; driving through suspect neighborhoods, dimly lit areas, walking distances too far for comfort, just being out in public after dark in general, etc. Like choosing to play Blackjack over all other betting games, because the odds are better.
Food for thought, less than a week after this post two guys armed with rifles and body armor attacked an art show in Dallas.
