 In 2012, Marshalltown, Iowa launched a proactive Not In Our Town Anti-Bullying Campaign.The model rests on several core assumptions, namely that cross-constituency engagement gives everyone a voice and leads to great inclusion; bystander behavior must be addressed and that any single person can become an "upstander" to support victims; and that positive stories can offer solutions and help shift community norms.To help equip communities, the project provides specific films, resources and training for these key stakeholders.
