Teaching people to use common sense. Teaching teachers and students to listen. Work on compassion.

The issue of violence is the schools is not new. Check history books, it has been going on for decades. Do you honestly think the schools are more violent today than they were when you were a student? Yes, we can see instances of copycat killings and the media intensity has highlighted issues, but the times have not changed that much. Slapping band-aid terms like "zero tolerance" and creating unmanageable programs has not proven anything.
