David Frum, today:

A permissive gun regime is not the only reason that the United States suffers so many atrocities like the one in Connecticut. An inadequate mental health system is surely at least as important a part of the answer, as are half a dozen other factors arising from some of the deepest wellsprings of American culture.

Nor can anybody promise that more rational gun laws would prevent each and every mass murder in this country. Gun killings do occur even in countries that restrict guns with maximum severity.

But we can say that if the United States worked harder to keep guns out of the hands of dangerous people, there would be many, many fewer atrocities like the one in Connecticut.

And I’ll say: I’ll accept no lectures about “sensitivity” on days of tragedy like today from people who work the other 364 days of the year against any attempt to prevent such tragedies.

It’s bad enough to have a gun lobby. It’s the last straw when that lobby also sets up itself as the civility police. It may not be politically possible to do anything about the prevalence of weapons of mass murder. But it damn well ought to be possible to complain about them - and about the people who condone them.
