Racial disparities have long been evident in the U.S. criminal justice system, but a new report drilling into statistics on wrongful convictions points up exactly how nefarious the problem is. African Americans are much more likely to be wrongfully convicted of a murder, sexual assault or drug offense than whites. The report, by the National Registry of Exonerations, found that "innocent black people are about seven times more likely to be convicted of murder than innocent white people," and thus also account for a disproportionate share of the growing number of exonerations. African Americans who were convicted and then exonerated of murder charges also spent four years longer on death row than wrongfully convicted whites (and three years longer for those sentenced to prison). According to the report, African Americans convicted of murder "are about 50% more likely to be innocent than other convicted murderers," and that such wrongful convictions, even when later corrected, expands the impact of violence on African American communities.
