In this episode, Alma Guillermoprieto discusses her article “Mexico: The Murder of the Young,” in which she follows the story of 43 students from a teacher's college in the Mexican state of Guerrero who disappeared last year at the hands of corrupt police and a local drug gang. She describes how the search for their bodies revealed that much of the state is a gravesite, and reflects on what distinguished this event from the many thousands of murders that preceded it.
