Final answer:
The answer is C. Foreign Intelligence Surveillance Act (FISA). It is a U.S. law that governs the surveillance and collection of foreign intelligence information, including espionage or terrorism.
Step-by-step explanation:
The answer to the question is C. Foreign Intelligence Surveillance Act (FISA).
The Foreign Intelligence Surveillance Act (FISA) is a U.S. law that prescribes procedures for the physical and electronic surveillance and collection of "foreign intelligence information" between foreign powers and agents of foreign powers. This may include American citizens and permanent residents suspected of espionage or terrorism.
FISA allows the government to collect intelligence information on individuals who are suspected of being agents of foreign powers and engaged in espionage or terrorism. It establishes a specialized court, called the Foreign Intelligence Surveillance Court (FISC), to oversee requests for surveillance warrants.
The aim of FISA is to strike a balance between protecting national security and civil liberties by providing a legal framework for electronic surveillance in cases involving foreign intelligence and national security. It is an important tool for law enforcement agencies in their efforts to prevent terrorism and protect the country.
