What are some steps that schools and communities can take to minimize bullying in schools?

There has been a lot of talk about bullying in the media as of late, Obama held a White House conference on bullying prevention a few months back and various campaigns against it and I was just wondering what do you think would be some good ways to go about reducing bullying within schools here in America.

Do you agree or disagree with the general trend of increased involvment with law enforcement for cases of bullying or do you think that bullying should be handled by the schools unless there are severe circumstances?

Do you think that more stringent speech codes similar to what is seen in some universities would improve the situation or make things worse?
