 Scott told "Newsweek", "...principals and teachers always need to be on the lookout for that kid who's isolated, or that's quiet, who always stays to himself, because that's typically the type of kid who ends up exploding.They also need to create an atmosphere in the school where students share with someone if they ever hear or see a threat.We know there have been numerous school shootings prevented because a student saw another student writing that he wanted to kill someone or something like that.
