The massacre inside a chained-shut Norris Hall went on for nine minutes as Seung-Hui Cho fired off 170 rounds, killing 30 people before shooting himself in the head, police revealed Wednesday. But they said investigators still don't know why Cho launched the bloody attack on his fellow students at Virginia Tech.
Good god, that's 10 reloads for the Glock (had he used only the Glock, I know he didn't) PRE BAN. Assuming he had to fire the .22 and possibly deal with other magazines AND had no training, it appears that he was not rushed!?!?
