It's been 54 years since Dr. Martin Luther King Jr. was assassinated on April 4, 1968 on a balcony of the Lorraine Motel in Memphis, Tenn, where he had gone to support sanitation workers on strike for equitable pay and safer working conditions.

In the passing years, it seems King and other stalwarts of the civil rights movement have faded into distant memory, their work, their sacrifices, their lives and accomplishments fading into the past, too.

Have we "gotten over" them? Have we "moved on?"
