Newsweek: The Feds can track you via your cell phone.
It's not enough that they can access your credit card spending, bank account information and email content... no... not enough. They want to know more.
excerpt: "How many of the owners of the country's 277 million cell phones even know that companies like AT&T, Verizon, and Sprint can track their devices in real time? Most "don't have a clue," says privacy advocate James X. Dempsey. The tracking is possible because either the phones have tiny GPS units inside or each phone call is routed through towers that can be used to pinpoint a phone's location to areas as small as a city block. This capability to trace ever more precise cell-phone locations has been spurred by a Federal Communications Commission rule designed to help police and other emergency officers during 911 calls. But the FBI and other law-enforcement outfits have been obtaining more and more records of cell-phone locations—without notifying the targets or getting judicial warrants establishing "probable cause," according to law-enforcement officials, court records, and telecommunication executives. (The Justice Department draws a distinction between cell-tower data and GPS information, according to a spokeswoman, and will often get warrants for the latter.)"
