The new film "Crown Heights" depicts the story of Colin Warner, an African American man who spent 21 years in prison for a murder he didn't commit.
His story isn't uncommon. A study conducted by the National Registry for Exonerations, which is hosted at the School of Social Ecology, found that nearly 47 percent of the 1,900 people exonerated as of October 2016 were black, a rate three times higher than their proportion in the general population.
"Judging from the cases we know, a substantial majority of innocent people who are convicted of crimes in the United States are African Americans," the report says.
The report was quoted in Think Progress.
