The phrase “Minneapolis police reform” may bring to mind the events of 2020. The murder of George Floyd that year made the city the center of worldwide calls to change policing. It led the city to enter a process of court-ordered reforms that are still taking shape.

A new documentary looks back much further. In “Paradox: Echoes of Reform & the Minneapolis Police,” historian Yohuru Williams traces local politics, community activism and police union organizing over 150 years of Minneapolis policing history. The film by Twin Cities PBS premieres Tuesday night.

Yohuru Williams, along with the film’s executive producer Daniel Bergin, joined MPR News host Nina Moini to discuss the documentary.
