This guide is intended to be a primary resource for law enforcement officers who play a large role in helping to educate and support children and adults about the problems resulting from bullying, teasing, and all forms of bias; ways to prevent and intervene in bullying situations; and how to break cycles of bullying and transform student behavior. Also featured are anecdotes from the Not In Our School campaign, an ongoing commitment to empower students to create safe and inclusive environments. The background information and strategies presented apply to young people from all ethnic groups, genders, and ages, from preschool to high school.
