We should probably just have one thread given the regularity with which it happens.
In today's fun and games, a gunman has opened fire in a high school in Colorado, 10 miles from Columbine. There were reports of injuries, currently it looks like the shooter is injured and the school is being evacuated.
Update: shooter is dead from a self-inflicted injury. Was a student.
Further update: one student seriously injured with a gunshot wound, another not so serious. Shooter was apparently after a specific teacher.
