Newly disclosed internal documents have confirmed the Roman Catholic Archdiocese of Los Angeles deliberately hid evidence of child molestation for more than a decade. The now-retired archbishop, Cardinal Roger M. Mahony, and other high-ranking clergy officials made extensive efforts to transfer abusive priests out of state to avoid prosecution and to stop them from confessing to therapists who would have been forced to inform police. The church reached a $660 million settlement with 500 victims in 2007, the largest of any Roman Catholic diocese. In reaching the deal, it spared top church officials from having to testify in court. A Los Angeles judge is set to rule next month on whether two church officials will face new depositions in a civil lawsuit over the abuse.
