• 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.

One-paragraph order

One such warrant seen by the Guardian shows that they do not contain detailed legal rulings or explanation. Instead, the one-paragraph order, signed by a Fisa court judge in 2010, declares that the procedures submitted by the attorney general on behalf of the NSA are consistent with US law and the fourth amendment.
