Title 50 › Chapter 36— FOREIGN INTELLIGENCE SURVEILLANCE › Subchapter II— PHYSICAL SEARCHES › § 1821
Gives plain meanings for words used in this part. Several terms use the same meanings as in section 1801: "foreign power", "agent of a foreign power", "international terrorism", "sabotage", "foreign intelligence information", "Attorney General", "United States person", "United States", "person", "weapon of mass destruction", and "State". An "aggrieved person" is someone whose place, property, information, or stuff was physically searched. The "Foreign Intelligence Surveillance Court" is the court set up by section 1803(a). "Minimization procedures" are rules the Attorney General must create to limit collecting, keeping, and sharing nonpublic information about U.S. persons unless needed for foreign intelligence; they must also bar sharing identifying nonpublic info about a U.S. person without consent unless the identity is necessary to understand or judge the intelligence, allow keeping or sharing evidence of crime for law enforcement, and—for physical searches approved under section 1822(a)—require that U.S. person information not be used, shared, or kept longer than 72 hours unless a court order under section 1824 is obtained or the Attorney General finds a threat of death or serious bodily harm. "Physical search" means a physical intrusion inside the U.S. into places or property (including technical inspection) meant to seize, copy, inspect, or alter information or items where a person would expect privacy and a warrant would be needed for law enforcement, but it does not include "electronic surveillance" or certain foreign-intelligence collection from foreign communications systems done under other federal law.
