Strategically speaking, I agree, Emil. Guns are a deterrent to burglary. Here's a stat from Jeffrey Goldberg's article,
The Case For More Guns (and More Gun Control); from this month's Atlantic Monthly (a left-leaning magazine):

But tactically speaking, I'm a pragmatist. So, it's 2am, El Sancho and his Señora are happily tucked in their bed when they are startled awake by a burglar crashing around downstairs, stealing their TV set. My plan is to get my people out of the house to a safe place and call the cops. We have a crappy TV anyway, and we have good homeowner's insurance. Any confrontation, armed or not, creates an extremely dangerous situation. I'll fight, but only if the flight option is taken from me (caveman instinct), in which case Señor Bandito will have to deal with the wrath of El Sancho and his old lady. La Señora may be small, but she's got fight. She knows how to shoot, but she prefers knives and chainsaws.
That's all just a hypothetical situation anyway, because any burglar who breaks into La Casa del Sancho will almost immediately be licked to death by our recklessly friendly Spaniels; either that or he'll be pressured into a game of throw-me-the-ball-and-make-it-snappy.
