In 1967, Martin Luther King, Jr. spoke of “the giant triplets of racism, economic exploitation, and militarism.” 52 years later, every day still feels like Groundhog Day when it comes to injustice. To talk about the progress, or lack thereof, we're joined by NBC news analyst and current Fair and Just fellow at Brooklyn Community Foundation, Heather McGhee. Then, to talk about the case that led to the complicated copyright conundrum that makes it very challenging and expensive to use any of MLK's speeches, we're joined on the phone by author and historian David J. Garrow.
