As I watch the search for Dzhokhar Tzarnaev (the 19-year-old Boston bomber), a thought occurred to me. Bostonians have been told to stay indoors and not open their door to anyone knocking or ringing the door bell except a police officer. Of course, many, maybe even most front doors, don't have a way to confirm that someone coming to the door and saying "police". . . really is. Given that situation, and the probability that Tzarnaev would like to find a hiding place in a home, if I lived in Boston, I would feel MUCH better if I had a Glock, and would DEFINITELY have it in a holster or in my belt the entire time until Tzarnaev is captured or killed. It would be out and aimed at the door if ANYONE knocked on it. So when I open it, whoever is on the other side would be facing my loaded Glock until I identified them.
But what if this were Chicago. . . which bans guns?
