Nearly two decades since its initial passage in the aftermath of the 9/11 attacks, the Patriot Act has continued to linger in our collective memory. Though few Americans probably remember much about its provisions or specifics, the Bush-era legislation long ago entered into general usage as an synonym for heavy-handed domestic surveillance and institutional overreach — the words “Patriot Act” now being practically synonymous with secrecy, eavesdropping, and the rolling back of civil liberties under the intentionally broad guise of “national security.”

Given the law’s contents and implications in practice, this reputation is well deserved. Passing the Senate with only a single dissenting vote, the Patriot Act dramatically expanded the power of federal authorities to spy on ordinary Americans with minimal oversight: enabling the FBI to obtain detailed information about citizens’ banking history and personal communications without having to seek judicial approval and even allowing “sneak and peek” searches of homes and offices. “The Patriot Act,” in the rather blunt words of a brief prepared by the ACLU, “[turned] regular citizens into suspects.”

Predictably, a great deal of law enforcement activity resulted from the ludicrously titled law (USA PATRIOT was a backronym for “Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism”). According to data released by the Department of Justice, the FBI made hundreds of thousands of incursions into personal phone, computer, and financial records in the years immediately following its passage — the utility of these searches in identifying or preventing actual terrorist activities being debatable, to say the least.
