"Judging from exonerations, innocent black people are about seven times more likely to be convicted of murder than innocent white people. A major cause of the high number of black murder exonerations is the high homicide rate in the black community—a tragedy that kills many African Americans and sends many others to prison. Innocent defendants who are falsely convicted and exonerated do not contribute to this high homicide rate. They— like the families of victims who are killed—are deeply harmed by murders committed by others."

7x more murders per capita, 7x higher rates of false conviction. It's simple scaling. That means the system is being perfectly equitable.
