“How the surveillance state co-opted personal technology”
“Big Brother has been outsourced. The police can find out where you are, where youve been, even where youre going. All thanks to that handy little human tracking device in your pocket: your cellphone.”
“The phones communicate via a nationwide network of nearly 300,000 cell towers and 600,000 micro sites, which perform the same function as towers. When they are turned on, they ping these nodes once every seven seconds or so, registering their locations, usually within a radius of 150 feet. By 2018 new Federal Communications Commission regulations will require that cellphone location information be even more precise: within 50 feet. Newer cellphones also are equipped with GPS technology, which uses satellites to locate the user more precisely than tower signals can. Cellphone companies retain location data for at least a year. AT&T has information going all the way back to 2008.
Police have not been shy about taking advantage of these data. According to the American Civil Liberties Union (ACLU), U.S. law enforcement agencies made 1.5 million requests for user data from cellphone companies in 2011. And under current interpretations of the law, you will never find out if they were targeting you,” quoting Ronald Bailey from the January 2013 issue of Reason.com.
