That report's really long. Is there any suggestion that, besides using validated techniques, the forensic investigators themselves be cross-validated -- where they don't know if they're getting cases from the "training set" or the "test set"? (And neither do the people they're directly in contact with.) If it's justified for machine learning for ad systems, I fancy that sort of check is justified for justice, too.
