TSA

The Transportation Security Administration (TSA) is a United States federal agency responsible for security within the nation's transportation system. It is part of the Department of Homeland Security and was created in response to the September 11, 2001 attacks, beginning operations in 2002. TSA's primary mission is to protect travelers and the U.S. transportation network by preventing dangerous items from entering secure areas. The agency conducts passenger and baggage screening at commercial airports and sets security standards for screening equipment, personnel, and procedures. It also oversees related programs such as the Federal Air Marshal Service and, where airports use them, private screening contractors under TSA oversight.

Organization and scope: The Administrator of TSA is a presidential appointee confirmed by the Senate. The agency operates under the Department of Homeland Security and coordinates with airlines, airports, law enforcement, and other federal partners to implement security measures across the aviation system and other transportation modes as needed.

Screening methods and programs: TSA employs technology such as X-ray and CT scanners, metal detectors, and Advanced Imaging Technology, along with canine teams and passive monitoring. It administers programs intended to speed trusted travelers through screening, notably TSA PreCheck, and maintains other risk-based screening initiatives. The agency also develops security policies, training, and incident response procedures.

Controversy and reception: TSA has faced criticism over privacy concerns related to screening methods, including body scanners and pat-downs, as well as concerns about wait times and perceived profiling. In response, TSA has introduced privacy measures, opt-out options, and faster screening processes to balance security with civil liberties and traveler convenience, while continuing to enforce screening requirements for air travel.
