Alicia Garza, co-founder of Black Lives Matter and a community organizer, talks about Martin Luther King's legacy, the fight for racial justice today and why she doesn't look forward to Martin Luther King Day.

Vincent Harding was Martin Luther King's longtime friend and advisor. They first met in 1958 when King was laid up in bed, recovering from an assassination attempt. Harding said King's death made some people in the civil rights movement wonder if the country was worth fighting for.

Clayborne Carson, the director of the King Papers Project, says Martin Luther King Jr. was an "accidental" civil rights leader. Carson argues we created another King -- someone he never was -- the moment he died.
