Dick Cheney's security clearance

Dick Cheney has been asking the Obama administration to release certain pages of certain classified documents, in order to "prove" that torture works. Here's a question: How does a 68 year old man remember specific pages of specific documents when he left his job over three months ago and, presumably, presumably lost his access to those documents at the time he left the White House? Did Cheney take copies of classified documents with him? Is someone leaking Cheney information about classified documents? Did Cheney takes notes on classified documents, which would themselves be classified?

Consider the amount of paperwork the vice president of the United States sees on a daily basis. Then consider that Cheney held the job for 8 years. We're to believe that he can remember specific pages of specific documents well enough to request in writing that those specific pages and documents be declassified? I smell a leak.
