This isn't quite the same thing as saying someone who was carrying concealed would have caused more problems. The statistics show that having an armed civilian present would have been unlikely to make things worse.



He shot two people. I wasn't there and I don't know anything about how this went down other than in the link to the news story, but it's conceivable that someone who was carrying concealed might have been able to prevent one or both of the victims from being shot. It's also possible that the situation was such that it wasn't preventable by someone carrying concealed. We may never know.



How do you know that? I'm not saying you're wrong, because I sure as heck don't know, but you'd have to be in possession of more information about the incident than I am to be sure.
