Virginia Tech Shooting

Ever since the Virginia Tech shootings, people have been wondering what could have been done to prevent Seung-Hui Cho from going on his rampage. The New York Times reported that Cho had shown signs of having problems every since his youth:

From the beginning, he did not talk. Not to other children, not to his own family. Everyone saw this. In Seoul, South Korea, where Seung-Hui Cho grew up, his mother agonized over his sullen, brooding behavior and empty face.
