Jason Sokol, professor of history at the University of New Hampshire, talks about his book "THE HEAVENS MIGHT CRACK: The Death and Legacy of Martin Luther King Jr.”. In it he gives context to how Americans, and others around the world, grappled with King’s death in the days, weeks, and months afterwards. He reveals how the consequences surrounding King’s assassination shaped not only his legacy, but the course of the Civil Rights Movement, and race relations in America.
