For decades, California's strict police privacy laws made it nearly impossible for anyone to find out basic information about police officer misconduct. A team of Los Angeles Times reporters spent months investigating the impact of this secrecy on the criminal justice system. They found that officers caught for dishonesty and other serious wrongdoing were able to continue testifying in court without prosecutors, defendants, judges and jurors ever finding out about their past. Countless defendants were convicted based on the testimony of these officers. Published at the height of a political debate over making police records public, the stories helped galvanize support to change state law and open up some records about officer misconduct, which had been kept confidential for 40 years.
