Why not instead focus on the source of the problem: the very small minority of mentally ill people who pose a danger to themselves and others. And, yes, guns need to be part of that equation. But blanket efforts to ban guns seem like an analogous effort to ban dangerous speech or art. About a third of U.S. households own a gun, according to surveys, but the number may be higher than that. Getting rid of guns will infringe on the rights of tens of millions of sane, law-abiding citizens in order to tackle a problem posed by dozens of people. And, like it or not, the Supreme Court has reaffirmed that we have a constitutional right to own a firearm, subject to reasonable regulation.
