I one other person in that dorm at Virginia Tech would have had a concealed handgun permit with a handgun, the death toll would have been much lower.
Correction to Post #41:
“If one other person......”
I agree with your sentiment, but Norris Hall is a classroom, lab, and office building. Norris Hall is not a dormitory at all. As far as we know, no one saw Cho in the dormitory (Ambler-Johnson). I know it's a small point, but it's a mistake that bothers me when I hear people making it.
Otherwise, I agree completely. If a grad student in one of the labs were carrying, he could have come upstairs with his firearm ready. If Dr. Granata had been armed, he would have had an excellent chance of stopping Cho. Dr. Granata's military training likely would have made him much better in armed combat than some evil-crazed kid. He probably recognized the sound of gunfire and responded to try to save lives. If he'd only had the right tools, maybe the incident could have ended sooner.
