How 9/11 changed the way America surveils its citizens

Twenty-five years after the September 11 attacks, the surveillance systems built in their wake have folded into a much larger digital ecosystem capable of collecting and analyzing information at a scale unimaginable in 2001, according to independent reporting. Joint terrorism task forces and fusion centers expanded intelligence-sharing across federal, state and local agencies, while new laws widened the government's ability to obtain information and pushed national-security tools into everyday policing.

Experts cited in the report say the shift has accelerated: automated license plate readers, facial recognition, cellphone location data and commercial data brokers now feed into systems that artificial intelligence can search and connect in seconds. Civil liberties advocates warn these tools have been used to monitor protests, track immigrants and identify people seeking reproductive healthcare, while fusion centers originally built to stop terrorism have drifted into supporting investigations of lower-level crimes.

American Muslims and immigrant communities bore a disproportionate share of the post-9/11 scrutiny, the report notes, even as most Americans accepted expanded surveillance as a safety tradeoff. A quarter-century later, the tradeoff has outlived the original justification and kept growing anyway.
