I would be a dollar to a doughnut hole that Sandy Berger copped documents that had comments about Able-Danger written in the sidebars.
The press was quick to say that copies of the documents he stole were still within the National Archives. What they did NOT say, was that the originals, with hand-scribed commentary were stolen and never to be seen again.
Probably Bill Clinton saying "We can't respond to this Able-Danger stuff, it violates the separation of FBI and CIA clause written by our staff..."
There is absolutely no doubt in my mind that the documents Sandy the Burglar stole were directly related to Able Danger.
