Hack might have helped to facilitate the leak of the photo's, but someone leaked the report to the press to go along with the pics. Joe Scarborough was complaining the night before 60 Minutes II was going to air the pics, about the fact that he had the report, yet the DoD didn't.
I think I can smell a crusty pantsuit involved in the leak of this report, See this thread below
Did Hillary reveal who leaked report in her questioning of Rumsfeld today?
This onion has many layers and it goes back to the strategy uncovered in "memogate".
