Don't be so sure.
And don't be so sure that a lone person with a gun has much protection against even a small gang of persons who are also armed; certainly training can help to even those odds, but most people are not even trained in how to shoot, let alone in defense tactics.
Specifically saying "nut jobs" should be able to legally bear arms, probably not; but then defining what a nut job is proves very difficult. Is a man who hit his wife and threatened her enough of a nut job so he should be denied that right. Where is that line drawn. And some will argue against each and every restriction as "whittling away our rights" --a frequent NRA position.no one is arguing that nut jobs should be able to legally bear arms.
And how do we screen nut jobs? Should we have a waiting period to allow for the background check? A lot of people would scream no. Or limitations on private sales except when a firearms dealer runs a background check? Same screams.
Face it, we need to get a workable system in place to enforce even our current laws, but that's the last thing some on the other side of the debate want.
