The CIA released their "family jewels" yesterday, a series of documents detailing abuses of power. You can read it at the CIA’s Freedom of Information Act Electronic Reading Room, but it’s over 700 pages long, so you might want to download it from The National Security Archive to peruse at your leisure. The CIA also released the CAESAR-POLO-ESAU papers, which is a detailed (11,000 fucking pages detailed) analysis of Soviet-Chinese relations and internal politics during 1953-1973.
In related news, the US Senate has issued a subpoena for documents relating to (possibly illegal) surveillance of US terror suspects.
