ARLINGTON (CBS) – Ninth graders from Arlington High School are the stars of a new anti-bullying documentary. On Friday, students got to see their hard work first hand with a screening of the film.

The short documentary looks at ways of reducing violence in our communities.

It examines differences and discrimination, whether it’s through name-calling, teasing, pushing, scapegoating, bullying, or hate-crimes.

Students learn how to build more peaceful communities by studying the experiences of survivors and perpetrators of the Rwanda genocide.

The documentary comes as people around the country reflect on how to respond to the massacre in Newtown, Connecticut.

The film is part of a campaign launched by Coexist, a Boston-based educational documentary film project.
