Suggested film: 13th
From Wikipedia: 13th is a 2016 American documentary by director Ava DuVernay. The film explores the "intersection of race, justice, and mass incarceration in the United States;" it is titled after the Thirteenth Amendment to the United States Constitution, which freed the slaves and prohibited slavery, with the exception of slavery as punishment for a crime.
DuVernay contends that slavery has been perpetuated in practices since the end of the American Civil War through such actions as criminalizing behavior and enabling police to arrest poor freedmen and force them to work for the state under convict leasing; suppression of African Americans by disenfranchisement, lynchings and Jim Crow; politicians declaring a war on drugs that weigh more heavily on minority communities and, by the late 20th century, mass incarceration of people of color in the United States. She examines the prison-industrial complex and the emerging detention-industrial complex, demonstrating how much money is being made by corporations from such incarcerations.
13th has garnered acclaim from film critics. It was nominated for the Academy Award for Best Documentary Feature at the 89th Academy Awards, and won the Primetime Emmy Award for Outstanding Documentary or Nonfiction Special at the 69th Primetime Emmy Awards.
