WELL REGULATED?

First paragraph of "People Don't Stop Killers. People with Guns Do," an op-ed by Glenn Reynolds in the New York Daily News:

On Monday, as the news of the Virginia Tech shootings was unfolding, I went into my advanced constitutional law seminar to find one of my students upset. My student, Tara Wyllie, has a permit to carry a gun in Tennessee, but she isn't allowed to have a weapon on campus. That left her feeling unsafe. "Why couldn't we meet off campus today?" she asked.

May I say something harsh here? If there's a maniac on the loose in central Virginia and that makes you afraid for your safety in Tennessee, then I'm not exactly sure I want someone with your temperament carrying a gun at my school.
