From the D.C. Examiner:
This is the classic case in which someone would say, if the assailant had a license, guns make it easier to commit acts of violence. But what would have happened if a number of these folks had the benefit of concealed carry? Anti-gun activists suggest that we’d see a nasty fire-fight, but consider a world in which it’s more likely that people nearby have firearms on their person — do you think the assailant would take that risk?
UPDATE: Speaking of homegrown terror, one can’t help but ask, after looking at this photo of Andy Dick: “WHY SO SERIOUS?”
