[email protected]. The Fourth Amendment's National Security Exception: Its History and Limits L. Rush Atkinson 66 Vand. L. Rev. 1343 (2013) Each year, federal agents conduct thousands of "national security investigations" into suspected spies, terrorists, and other foreign threats. The constitutional limits imposed by the Fourth Amendment, however, remain murky, and the extent to which national security justifies deviations from the Amendment's traditional rules is unclear. With little judicial precedent on point, the gloss of past executive practice has become an important means for gauging the boundaries of today's national security practices. Accounts of past executive practice, however, have thus far been historically incomplete, leading to distorted analyses of its precedential significance. Dating back to World War II, national security investigations have involved warrantless surveillance and searches-conduct clearly impermissible in the traditional law-enforcement context- authorized under the theory of a "national security" or "foreign intelligence" exception to the Fourth Amendment.
