“guess the question is, how paranoid do you want to be? How many guns does it take to make you feel safe? And how do you simultaneously keep them loaded and close at hand, but still out of reach of your inquisitive children or grandchildren? Are you sure you wouldn’t do better with a really good burglar alarm? It’s true you have to remember to set the darn thing before you go to bed, but think of this — if you happened to mistake your wife or live-in partner for a crazed drug addict, you couldn’t shoot her with a burglar alarm.”
