A US Marine is wounded and a Reuters photographer captures what happened.  Years later, both are still alive, both are back home, and both are struggling to transition to something different from combat.  Thomas Brennan, the former platoon sergeant and Finbarr O’Reilly have written a fine book SHOOTING GHOSTS about how their friendship helped change their lives.  We talk about 2 questions never asked on the battlefield: “Why are we here?” and “Whose lives are we making better?”
