Dallas County District Attorney John Creuzot ran for office on a platform of ending mass incarceration and reforming the county's criminal justice system. Last April, Creuzot announced steps his office was taking toward that goal. Among other changes, Creuzot declared that he would no longer prosecute misdemeanor marijuana cases for first-time offenders or cases involving people arrested for possession of trace amounts of drugs, driving with a suspended license or stealing necessary items. It's too early to say how effective these changes will be, but it's always good to see an elected official walking the criminal justice reform talk.
