From The Washington Post: A disgruntled 20-year-old student walked into a classroom at the Northern Virginia Community College campus in Woodbridge on Tuesday afternoon and fired at least two shots from a high-powered rifle at his math teacher. The teacher saw the gun, yelled for her 25 students to duck and then hit the floor. The student's shots missed. He put the gun down, sat on a chair in a fourth-floor hallway and calmly waited for police. Jason M. Hamilton was charged with attempted murder and discharging a firearm in school zone.
