This 2010 certification from the Director of National Intelligence and the Attorney General asserts that procedures are in place to ensure foreign intelligence gathering stays within the boundaries of the law by targeting people “who are reasonably believed to be outside the United States.” The breadth of the authority is, however, very wide, allowing surveillance of communications “about” 193 countries and other entities specified in a separate document: see the Washington Post article Court gave NSA broad leeway in surveillance, documents show, 30 June 2014.
This NSA Staff Processing form from 6 September 2006 describes some of the problems relating to the expansion of the raw FISA information made available to NSA field offices. Referring to different classes of FISA information being stored together the memo concludes that “it is possible that there are already FISA violations resulting from the way data has been stored in these databases”: see the New York Times article How a Court Secretly Evolved, Extending U.S. Spies’ Reach, 12 March 2014.
This 20 August 2002 memo from US Attorney General John Ashcroft refers to the “modified minimization procedures” now in operation following the FISA Court’s “Raw Take” order of 22 July 2002 and expands on that order by allowing the sharing of information with foreign governments without the need for authorisation to be sought: see the New York Times article How a Court Secretly Evolved, Extending U.S. Spies’ Reach, 12 March 2014.
A Memorandum of Understanding (MOU) between the NSA and the Israeli SIGINT National Unit that allows the NSA to share “raw SIGINT data” with Israel.
