Berger took the after action report for the millenium bombings, specifically certain drafts of the report.
the issue of the "notes in the margin" has become one of those "folklore" things now. The left claims the archives has copies of everything, they were submitted to the 9-11 commission, there are no "secret notes", that Berger essentially did nothing wrong because he destroyed copies of documents, he wasn't trying to hide anything. But other articles I have read note that Berger sifted for specific drafts of the report at the archives, that some specific draft had the notes in question, and this is what he grabbed.
that story makes the most sense - after all, why would you steal and destroy documents you knew there were exact copies of (like the final official version of a report) - what's the point.
Question .. any chance these original draft documents would have been scanned through microfiche??
Or more precisely: Why would you keep going back to steal multiple copies (versions) of the same document if they were really the same?
