answer:Stuff that comes to mind. * All forms that require or collect needless data such as address, phone number, SSN, birth date. * TSA body scanners, and trivia databases (see the recent question about the kid who forgot his ID but could identify himself to TSA by answering weird trivia about aunt’s job, or whatever). * The need to provide lots of personal information in order to receive insurance and medical care. * Computer chips inside passports. * Audio sensors designed to recognize and report explosions and gunfire. * Attachment of tracking devices on (foreign) cars crossing the border into the country. * The forests of electronic scanners at border crossings. * The 1984-like networks of security cameras in Chicago. * Databases kept by police and other government agencies on citizens who have not been convicted of crimes, and police equipped with networked computers which can look them up by car license plate number. * There have been Defense Department “requests for proposals” which are looking for ways to program computers to automatically analyze wiretap and other data from spying on the population, to determine who might be good targets to proactively eliminate because they might be likely to be hostile.
