From veterans returning from Iraq, to survivors of mass shootings, to those putting together the pieces after a hurricane--we know that the emotional and psychological scars of violence and tragedies sometimes last even longer than physical wounds.

But what is the psychological toll on those who help victims of traumatic experiences?

We talk with Dr. Megan Berthold, professor of social work at UConn, about the often-unrecognized "secondary" trauma that first responders, journalists, and aid workers, among others, sometimes experience in working closely with victims of trauma.

We also sit down with Michael Kehoe, the former Police Chief of Newtown, Connecticut, whose department responded to the school mass shooting at Sandy Hook Elementary School. We hear how the experience of that tragedy has led him to start a national conversation about mental health in police departments around the country.

And we hone in on the trauma journalists encounter covering tragic events, as well as the responsible ways media should report on trauma in their communities.

Do you work with people who have experienced trauma? How has that affected you?
