A FISA Primer: The Rules for Foreign Intelligence Electronic Surveillance

Electronic surveillance represents the most important foreign intelligence collection tool available to the U.S. government. Correspondingly, the ability to surveil constitutes one of those activities most susceptible to abuse by a government against its citizens. In the U.S., the government’s use of electronic surveillance is highly regulated and can be conducted for only two purposes: law enforcement, which is undertaken by both federal and state governments; and foreign intelligence collection, which is an exclusively federal government function conducted pursuant to a single authority - the Foreign Intelligence Surveillance Act or “FISA.” 

FISA governs not only electronic surveillance but the use of physical searches, pen registers, trap and trace devices, and business records collection to acquire foreign intelligence. It permits surveillance and other intrusive activities in the United States both with, and in limited circumstances, without a warrant. It covers virtually every major intelligence collection effort used by the United States, and constitutes the most important intelligence authority available in the war against terror.

This course will tell you everything you didn’t know about FISA, and may change your mind about some things you thought you did know about this crucial statute.
