A gunman opened fire at Virginia Tech after being pulled over in a traffic stop today, killing a police officer and another person on the same day university officials were in Washington, fighting a government fine over their handling of the 2007 bloodbath on campus. It was the first gunfire on campus since 33 people were killed in 2007 in the deadliest mass shooting in modern U.S. history.
