Just outside the historic Brown Chapel AME Church in Selma, Alabama, Amy Goodman had a chance to speak with the civil rights pioneer C. T. Vivian, a close friend and adviser to Dr. Martin Luther King Jr. Fifty years ago, Vivian was punched in the face by Dallas County Sheriff Jim Clark on the courthouse steps in Selma as he tried to escort a group of African Americans inside to register to vote. The punch was so hard, Clark broke his own hand. Vivian speaks about the power of nonviolence and the continued fight for voting rights.
