AMERICAN EXPERIENCE’s The Riot Report presents the story of the Kerner Commission and its first-of-its-kind 1968 government report that identified systemic racism as the cause of massive civil unrest in Black communities. But the results of the report were quickly buried by an administration afraid of potential political fallout. The film premieres on GBH 2 at 9pm on Tuesday, May 21, when it will also be available for streaming.
