The annual Denver Marade in honor of Martin Luther King Jr. is meant to be a peaceful event to remember a man who promoted non-violence. But more than 25 years ago in Denver things went terribly wrong. Jonthan McMillan was a security guard at the annual event in 1992 when Ku Klux Klan members rallied at the state Capitol. McMillan says the Klan's presence that day sparked violence between Marade marchers and police.
