I agree. I think the story is in the handwritten notes that were on some of the draft copies of the Millenium report, which Berger has now apparently destroyed. These notes could have been from Clinton officials, or even Clinton himself which showed Clinton's culpability for 9/11. It's not just about image management. Berger would not have committed such a serious crime for that. They are covering their guilt.
Probably they were thinking it was necessary in order to have Bush lose the election. Dirty tricks. Watergate. Sloppy break-in.
Great points!
