BLACKSBURG, Va. (April 19) — Students fell silent, restaurant patrons cringed and mothers turned their children away from the television. Two days after the worst killing spree in modern U.S. history, videos and photographs of an armed Cho Seung-Hui stunned the university community where he killed 32 people before committing suicide Monday. In the photos and recordings mailed to NBC midway through his rampage, the 23-year-old student delivered a snarling, profanity-laced tirade about rich "brats" and their "hedonistic needs." "You had a hundred billion chances and ways to have avoided today," he says in a harsh monotone. "But you decided to spill my blood. You forced me into a corner and gave me only one option. The decision was yours. Now you have blood on your hands that will never wash off."
