Apparently, a few teenagers in Kansas decided they would celebrate the anniversary of the Columbine shootings by killing a bunch of their classmates. The plot was foiled because one of them talked about it in a MySpace.com post. A fellow student read the post and notified the police, who arrested the would-be murderers, and found guns and knives in their bedrooms.

I heard about this yesterday in the waiting room of a doctor's office (they had CNN running on a TV in the room). An older couple was sitting behind me and when the story ran, she turned to her husband and said, "See? The Internet causes all sorts of trouble."

All she heard was "kids planning to kill classmates" and "Internet." Some folks will never learn...
