Dumb people & Guns, what a bad mix?

No, but it happens to innocent people who happened to be in the proximity of an IDIOT with a gun.

What about their rights? What about the rights of the victims of Sandy Hook?

Personally I don't care if some moronic gun owner shoots himself. Entirely voluntary and self inflicted, just like any dangerous sport junkie. But when they kill someone else, that's an entirely different issue, and one you second amendment slaves seem to ignore every time.
