Mayor Vincent C. Gray announced the creation of an anti-bullying task force Wednesday that intends to take an in-depth, comprehensive approach against bullying throughout the District.

The announcement was made minutes before a screening of “Bully,” a documentary that depicts such strong language among teenagers that the Motion Picture Association of America warned that the film might not be appropriate for children under 17.

The task force, which will include the heads of the school system, the city’s police department, the parks and recreation and the Office of GLBT Affairs, is expected to create best practices for teachers and adults on how to monitor and deal with bullying. The task force was part of an even larger “anti-bullying action plan,” which Gray said he hopes will lead to awareness and sensitivity training for city workers who interact with children.
