South Carolina, Alabama and other states are taking another look at the Confederate Flag and the history it represents. In the meantime, another kind of memorial is being proposed. Is it time to formally recognize the history of lynchings of black Americans? Bryan Stevenson is a Harvard-educated lawyer, who's argued cases before the US Supreme Court. He's also the grandson of an American slave, and founder of the nonprofit Equal Justice Initiative. This year, its research revealed that there were 3,959 lynchings of black Americans Between the end of Reconstruction in 1877 and 1950. That's 700 more than previously reported.
