A gun in every household? Certainly. You've got to fight like with like, only an idiot brings a knife to a gun fight.
But what KIND of gun?
It's 2006 people, bullets have been obsolete for years. Let's educate the people, you don't have to kill to defend yourself.
*EDIT*
I'm talking about educating people about the weapons that are available in our glorious 21st century. -In much the same way that the alternatives to fossil fuels have been covered up and ignored by the large companies which profit from old fuels, so it is with guns. I mean they've been around since what, the 1400s? It's really time we moved on from sharp bits of metal that kill so indiscriminately. The problem isn't in educating youngster not to play around and discover things on their own, that's probably all but impossible. And "unnecessary violence" isn't what you'll prevent, there are plenty of ways to do, the problem with firearms is that a single mistake kills - We need weapons that won't kill in such an easy fashion. One mistake is all it takes with the majority; safety switches are great inventions, but not nearly enough. Fingerprinted guns are ideal, but far too expensive for most, and let's remember lethality is NOT a requirement of home defence. Let's go to tranquiliser's and stun guns and tasers and leave these nasty, brutal instruments behind, much like the guillotine and torture chambers that were so favoured in those times.
