Secret Ratings of Airline Passengers and also ACLU No-Fly List Lawsuit
What's YOUR security rating? It could change every time you fly, and the goverment won't reveal how you rate.
Government officials say that the security rating will be based on credit information and secret law enforcement intelligence databases. Indications are that these shadowy collections of information could include personal data extracted from commercial and government sources. Could they include mistaken information? Sure. Who hasn't found errors in their credit reports and other commercial databases?
If you are given a yellow or red rating by mistake, it will be extremely difficult to clear your name.
