U.S. surveillance state continues to expand 25 years after 9/11

Twenty-five years after the September 11 attacks, the surveillance state established by the United States government continues to expand. Security measures, such as facial recognition at Transportation Security Administration (TSA) checkpoints and body scanners, have become deeply integrated into daily life.

These technologies are used to verify identities by comparing physical appearances with digital records, a process that has become a routine part of domestic travel and security protocols.
