(Originally broadcast June 24, 2010)  Last week we looked at youth violence as a structural and criminal justice issue. This week, we return to the topic of youth violence but will explore the issue through the prism of spiritual, mental, community, and public health.  Our panel: Phillip Martin, senior investigative reporter, WGBH Radio; Clementina Chery, president and CEO of the Louis D. Brown Peace Institute; Dr. Chidi Achebe, executive director of the Harvard Street Neighborhood Health Center; and Gary Bailey, associate professor of social work, Simmons College.
