JEFFREY GOLDBERG IN THE ATLANTIC: How do we reduce gun crime and Aurora-style mass shootings when Americans already own nearly 300 million firearms? Maybe by allowing more people to carry them.

And note this bit:

Universities, more than most other institutions, are nearly unified in their prohibition of licensed concealed-carry weapons. Some even post notices stating that their campuses are gun-free zones. At the same time, universities also acknowledge that they are unable to protect their students from lethal assault. How do they do this? By recommending measures that students and faculty members can take if confronted by an “active shooter,” as in the massacre at Virginia Tech.

These recommendations make for depressing reading, and not only because they reflect a world in which random killing in tranquil settings is a genuine, if rare, possibility. They are also depressing because they reflect a denial of reality.

Indeed.
