It seems like it's the parents' position to monitor the actions of their children on social media, not the school. What if they had been planning a fight from the public park. Should the school or police monitor their communication there? What if they had been planning a fight from their front yard. Should the school or police monitor them there? What about by phone? What about in their bedroom? "Planning a fight" is just communication. I don't think the school or the police should be monitoring children's communication (outside of the school premises, in the case of the school).
