Farmgirl recently posted an interesting and thorough discussion on the topic of gun-free zones at colleges.
She did leave out the fact that there was one man at VT who had the courage to charge the shooter. Liviu Librescu, a holocaust survivor and professor, charged the shooter, putting himself between the threat and his students. But she's right to point out that ours is a culture of submission, which is horrible. I've written about it many times already, so I'll spare my regular readers my own rantings on the subject. Just go read her take.
