National Security Surveillance - Constitutional Tension and Post-Snowden Reform
National security surveillance pits the president's Article II powers against Article III judicial limits. FISA (1978) balanced both. The PATRIOT Act loosened limits; the Snowden leaks (2013) drove reform, including the USA FREEDOM Act (2015) ending Section 215 bulk collection and the Judicial Redress Act (2016).
National security searches create a constitutional tension: Article II makes the president commander-in-chief with broad foreign-affairs power, while Article III vests judicial power in the courts. Katz emphasized judges' role but reserved the national security question; the Keith case left undecided the president's power over foreign-power surveillance. FISA (1978) gave supporters a statutory authorization for foreign-intelligence wiretaps and gave critics checks and balances.
The PATRIOT Act (post-9/11) added flexibility; later disclosures of warrantless surveillance led to the FISA Amendments Act of 2008. The 2013 Snowden leaks reinvigorated the debate, prompting the President's Review Group and PCLOB recommendations.
Reforms included the USA FREEDOM Act (2015), which ended bulk collection under Section 215, and the Judicial Redress Act (2016), which extended U.S. Privacy Act protections to certain non-U.S. persons.
National security exceptions vary by statute: HIPAA permits PHI disclosure to authorized federal officials for lawful intelligence and national security under the National Security Act; GLBA's exception is vaguer ("an investigation on a matter related to public safety"); COPPA makes no mention of a national security exception. The encryption "going dark" vs "Golden Age of Surveillance" debate (Apple v. FBI, 2016) illustrates the underlying tension.
