Berger was caught stuffing "hand written notes" into his pants/socks/jacket.
What is not made clear is if these were his own notes or was he stealing the comment notes made by others that were attached to the documents during their circulation.
He also stole entire documents, maybe because they had been commented in the body of the work instead of by attachment.
This makes sense to me, he appears to have been sanitizing the report by stripping out anything derogotary to the clinton regime.
The hand written notes were the dodge, if he got caught well they were just my notes. Figuring the people wouldn't have even noticed the extra papers stuffed in the briefcase. Second, why is he even allowed to bring an attache case into a secure room like that. Makes no sense, no notes allowed, can't take anything out, etc. Another case of two sets of rules
