From the early 1920s the Boy Scouts kept confidential files on adults barred for credible information of sexual misconduct toward children. University of Virginia researchers given the whole archive described three purposes: identifying offenders, recognizing them if they re-registered, and preserving evidence for litigation defense. The files reached the public through a 2010 Oregon trial, and the episode closes on the researchers' warnings.
A widely repeated 1919 origin date for the files could not be confirmed, and the page count of the 2012 release is disputed. The counts in the study do not measure total harm, and no comparable archive exists elsewhere to judge Scouting against other organizations.
