'US not come to terms with racial history'
One hundred and fifty years ago, the first shots of the US Civil War were fired in Charleston, South Carolina.

Speaking at Boone Hall Plantation outside Charleston, Powers says the US has still not come to terms with its racial history and suffers because of it.
