The Center for Prosecutor Integrity (apparently there is such a thing) has just issued this press release, announcing the the receipt of a grant to establish a Registry of Prosecutorial Misconduct.
In it, it states:
The Registry will eventually catalog thousands of cases of prosecutorial misconduct around the country. This information will allow policymakers to pinpoint priorities for reform.
The Registry will report the prosecutor’s jurisdiction, type of crime, type of misconduct, whether the case was referred to an ethics oversight body, whether sanctions were imposed, and other information.
Determinations of misconduct will be based on holdings of trial courts, appellate courts, state supreme courts, and legal disciplinary committees.
Maybe the next step can be to establish buffer zones for repeat offenders: you can’t get within 500 feet of a file without adult supervision.
