We cover three aspects of violence in Baltimore: Sun reporter Andrea McDaniels discusses her recent three-part series on the long-term effects of violence on victims' families; social worker Megan Leschak talks about her efforts to identify criminal defendants who have themselves been victims of violence and suffer from PTSD; and we meet James Timpson, director of Safe Streets Park Heights, on the role of "interrupters" in keeping young men from killing each other.
