A historical marker honoring Arthur Lee McDuffie, a 33-year-old Black man whose 1979 death at the hands of white Miami-Dade police officers sparked violent protests, has been knocked down near the Design District of the county’s Overtown area.

A new documentary called "When Liberty Burns" takes us back to the painful time National Guard troops on the streets of Miami. "It wasn't one death, it was so many things that caused it to explode all at once," he said. Many of Jones' black supporters felt the charismatic Dade County School Superintendent had been targeted. And so, the police beating death of McDuffie, the cover-up and the acquittal would be the tipping point. The documentary premiered at the Miami Film Festival and has already won awards.
