I'm not sure who's debating who here, but IIRC none of these massive shooting things have been ended by an armed populace. I don't think it would have helped...how can you stop someone who's so hell-bent on destruction and dying themselves? Just like you can't shoot a suicide bomber. They are already dead inside.
Now, robberies, home invasions, maybe some road rage stuff, gang bangers, sure. Guns (and an armed populace) are a great deterrent to people who are afraid of getting shot. This was not the case.
Just to be clear, I'm not anti-gun, just anti-taking in everywhere. Do I believe in CCW, sure I guess so. I know guys like Rick are pretty responsible, and probably most other CCW folks, but there's a time and place for everything. And I think that college campuses full of overstressed hormoned up young adults that are still trying to manage growing up, are probably not the place for weapons.
(However, truth be told, this is only because I'm thinking about it. I have been to VT a couple of times and attended VT's other campus. Never gave the fact I couldn't bring the gun I don't have to class.
