Yeah, I was researching things at the Washington Post, did a search, and the article came up. All I saw was the April 1 date and completely misssed the fact that it was 2005.
According to Bill Sammon's new book, Strategery, the documents stolen by Berger were drafts of a critique written by Richard Clarke of the Clinton administration's response to terrorist threats at the time of the millennium.
Sammon writes that Clarke's lawyer told the Washington Post that Clarke had written a "tough review" (p. 69).
