A Leading Cause for Wrongful Convictions: Experts Overstating Forensic Results

More than 150 men and women in American prisons were exonerated in 2018, according to a recent report by a registry that tracks wrongful convictions. Combined, these individuals spent more than 1,600 years in prison, a record for the database, which has data back to 1989.
The leading culprit in convicting innocent people was official misconduct, according to the report by the National Registry of Exonerations. Nearly one third of these cases involved a police corruption scheme in Chicago through which a police officer framed individuals on drug charges.
