The government is about to test a new risk-detection system for air travelers. It would assign a threat level to everyone who buys an airline ticket.
Delta Air Lines will try it out at three undisclosed airports beginning next month. The system -- ordered by Congress after the terrorist attacks -- is called Computer Assisted Passenger Prescreening System or CAPPS-Two. Advocates say it will weed out dangerous people. Critics say it will lead to unconstitutional invasions of privacy and could lead to innocent people being branded security risks.
