Revealed: the top secret rules that allow NSA to use US data without a warrant - Guardian

Document One.

Document Two.

If we stumble upon your data "accidentally", well, it's fair game...

• Keep data that could potentially contain details of US persons for up to five years;

• Retain and make use of "inadvertently acquired" domestic communications if they contain usable intelligence, information on criminal activity, threat of harm to people or property, are encrypted, or are believed to contain any information relevant to cybersecurity;

• Preserve "foreign intelligence information" contained within attorney-client communications;

• Access the content of communications gathered from "U.S. based machine[s]" or phone numbers in order to establish if targets are located in the US, for the purposes of ceasing further surveillance.

"The broad scope of the court orders, and the nature of the procedures set out in the documents, appear to clash with assurances from President Obama and senior intelligence officials that the NSA could not access Americans' call or email information without warrants.
The documents also show that discretion as to who is actually targeted under the NSA's foreign surveillance powers lies directly with its own analysts, without recourse to courts or superiors – though a percentage of targeting decisions are reviewed by internal audit teams on a regular basis."

From Truthout: Indefinite Surveillance: Say Hello to the National Defense Authorization Act of 2014 

NDAA 2014 builds on the powers granted by both the Patriot Act and FISA by allowing unrestricted analysis and research of captured records pertaining to any organization or individual “now or once hostile to the United States”. Under the Patriot Act, the ability to obtain “any tangible thing” eliminated any expectation of privacy. Under NDAA 2014 Sec. 1061(g)(1), an overly vague definition of captured records enhances government power and guarantees indefinite surveillance.On May 22, 2013 the Subcommittee on Intelligence, Emerging Threats and Capabilities, one of several Armed Services Committees, met to discuss the National Defense Authorization Act (NDAA) for Fiscal Year 2014. The main subject of the hearing was Sec. 1061, otherwise known as Enhancement of Capacity of the United States Government to Analyze Captured Records. This enhancement provision of NDAA 2014 would effectively create a new intelligence agency, one with the authority to analyze information gained under the Patriot Act, FISA, and known spying programs such as PRISM.Sec. 1061(a) authorizes the Secretary of Defense to "establish a center to be known as the 'Conflict Records Research Center'" (Center). The main purpose of the center, according to the bill text, is to create a "digital research database," one with the capability to "translate" and facilitate research on "records captured from countries, organizations and individuals, now or once hostile to the United States." The authorization also says the Center will conduct research and analysis to "increase the understanding of factors related to international relations, counterterrorism and conventional and unconventional warfare, and ultimately, enhance national security."
