"Actions by police officers, including witness tampering, violent interrogations and falsifying evidence, account for the majority of the misconduct that lead to wrongful convictions, according to a study released Tuesday by the National Registry of Exonerations that focused on the role police and prosecutors play in false convictions in the U.S. Researchers studied 2,400 convictions of defendants who were later found innocent over a 30-year period and found that 35% of these cases involved some type of misconduct by police. More than half – 54% – involved misconduct by police or prosecutors. The findings by the National Registry of Exonerations, a project that collects data on wrongful convictions, come as protests over racial injustice and police brutality spread across many cities for several months following the May 25 death of George Floyd in police custody.... Misconduct that leads to wrongful convictions rarely comes to light and doesn't usually lead to mass protests and a racial reckoning, although they involve the same reliance on secrecy and deception"
