The challenge is that we don't have, right now, a declassification program. In those cases we were talking about earlier, sometimes historical national security documents are still classified as secret or top secret and the process of going through an access request when those documents are considered sensitive is even harder for the analysts, and it's harder for our investigators because we have to demonstrate that the information is public or is already out there or that the sensitivity is not there anymore. It doesn't mean because it's classified it cannot be disclosed. It just adds that level of complexity.
