So here's an interesting twist to the story:

Apparently ALL 9 other people who were shot and wounded were actually hit by police bullets and not the gunman.
I wonder what that says about the argument I frequently hear - "If only there was someone carrying at [shooting spree location], this wouldn't have happened". Guns in the hands of good guys sometimes also create problems as much as they solve them... (not saying the police shouldn't have fired on the guy, of course)
