Neither the CIA nor the Department of Homeland Security will confirm or deny whether their government agents monitor the website Public Intelligence, invoking what's called the 'Glomar response'. The website, which posts regular updates about military and police actions and sensitive government documents, is a treasure trove of information about government spying. According to the site, DHS denied its request on the basis of protecting intelligence sources and methods, writing that it "neither confirms nor denies that such records may or may not exist." The CIA denied the request citing the National Security Act of 1947.
