The Boy Scouts of America has long kept an extensive archive of secret documents that chronicle the sexual abuse of young boys by scout leaders over the years. The "perversion files", a nickname the Boy Scouts are said to have used for the documents, have rarely been seen by the public, but that could change in the coming weeks in an Oregon courtroom. The lawyer for a man who was molested in the 1980's by a scout leader has obtained about 1,000 Boy Scout sex files and is expected to release some of them at a trial that began Wednesday. The lawyer said the files showed how the Boy Scouts have covered up abuse for decades. The attorney for the Boy Scouts said the that the files helped scouting leaders weed out sex offenders, especially repeat offenders who may have changed names or moved in order to join another local scouting organization.
