*Under both Section 702 and Executive Order 12333, various rules require the government to redact or delete any information about Americans (minimization procedures or masking) “incidentally” acquired during the warrantless surveillance. However, there are several exceptions. For instance, information about Americans that is necessary to understand foreign intelligence or that is evidence of a crime may be kept and shared. Moreover, once the government has collected the communications, it may search them for information about Americans, which (in the case of information obtained under Section 702) can be used in ordinary criminal cases as well as national security investigations. | *Under both Section 702 and Executive Order 12333, various rules require the government to redact or delete any information about Americans (minimization procedures or masking) “incidentally” acquired during the warrantless surveillance.
