The existence of the Boy Scout files – known as the "perversion files," listing scoutmasters or troop leaders accused of sexual abuse – has been known since a 2012 court case in the state of Oregon. But Anderson said a court case this year in Minnesota had revealed numbers of victims and perpetrators that were higher than previously known. He said the new figures came from an audit performed by Janet Warren of the University of Virginia, who has been working with the Boy Scouts of America. "She says there are over 12,000 victims identified in those files," Anderson said.
