I want to know your source for this because the last two cases in my archdiocese, one of which WAS true pedophilia, were made public less than a week after the archbishop was contacted. Both men were fast-tracked to laicization and both are in prison. One case, the victim was actually a teenage girl, was last year. The source, please, because the actual cases defy your statement.
