Bloody Sunday and "The Bridge Crossing Jubilee"

Hosted by

On "Bloody Sunday," John Lewis and other civil rights marchers were brutally attacked by police and soldiers on the Edmund Pettus Bridge in Selma, Alabama.

Tomorrow — just 50 years later -- President Obama and former President George W. Bush will be among the huge crowd that's expected to attend the "Bridge Crossing Jubilee" in Selma. It's a reminder of progress toward civil rights in America — and a reminder of failure.
