A student at Virginia Tech in Blacksburg, Va., opens fire in a dormitory and classroom building, killing 32 people. At the time, it is the worst mass shooting in modern U.S. history. The college was fined by the U.S. Department of Education for delaying notification of students. The shooting started at 7:15 a.m., but an email notification was not sent until 9:26 a.m. Forty-seven more people were shot after the notification. About 25 minutes later, another warning was sent by email, phone and loudspeaker. A jury later found Virginia Tech was negligent for delaying notification. Proposed gun-control legislation after the massacre goes nowhere.
