An investigation revealed over the weekend that the American Transportation Security Administration (TSA) is secretly monitoring and tracking hundreds of American citizens. They’re not on any kind of watchlist — the TSA just deems their flight patterns worthy of suspicion.

This program, called “Quiet Skies,” requires the TSA to keep an eye on certain US citizens when they’re in the airport. These citizens haven’t been accused of any crime, and they appear to have been selected for surveillance based on details in their movements that no one’s been able to adequately define.
