The psychological costs to children when bullets fly in Baltimore, plus activist Shirley Sherrod on healing from injustice.

When violence breaks out in neighborhoods, how do you address the psychological damage to young witnesses? We spoke with a Stanford University child psychiatrist who studied links between community violence and PTSD, and with a Baltimore public-school social worker.

Plus, it's been four years since Shirley Sherrod was fired from her federal agriculture job over an inaccurately reported speech. Sherrod told Tom Hall what lessons she took from that incident, and how a lifetime of witnessing inequality taught her how to fight it.
