After the tragedy at Sandy Hook Elementary School, PBS continues to analyze and illuminate the issues of access to guns and the politics of gun laws, mental illness in young adults, the science of detecting violent impulses and how communities react to unspeakable tragedy and begin to heal. The special brings together the resources of the PBS NEWSHOUR, FRONTLINE, WASHINGTON WEEK, NEED TO KNOW and NOVA. Gwen Ifill anchors the broadcast, which will include studio interviews and insightful discussion with regular contributors to WASHINGTON WEEK.
