The Surveillance State

How 9/11 transformed domestic surveillance, from the PATRIOT Act to the Snowden revelations.

The Architecture of Surveillance

The USA PATRIOT Act, signed six weeks after 9/11, dramatically expanded the government's surveillance authority. It lowered the bar for obtaining surveillance warrants through the Foreign Intelligence Surveillance Court (FISC), allowed 'roving wiretaps' that followed individuals across devices, and enabled the collection of business records (Section 215) with minimal judicial oversight.

The National Security Agency (NSA) went further than even the PATRIOT Act authorized. Under programs with codenames like STELLARWIND, PRISM, and UPSTREAM, the NSA collected bulk metadata on virtually every phone call made in the United States, tapped directly into the servers of major tech companies, and intercepted internet communications flowing through fiber optic cables.

These programs operated in secret for over a decade, overseen by classified FISC rulings that reinterpreted the law in ways that the law's own authors said they never intended.
