suraj.sun writes "If Americans aren't disturbed by phone carriers' practices of handing over cell phone users' personal data to law enforcement en masse — in many cases without a warrant — they might at least be interested to learn just how much that service is costing us in tax dollars: often hundreds or thousands per individual snooped(http://www.forbes.com/sites/andygreenberg/2012/04/03/these-are-the-prices-att-verizon-and-sprint-charge-for-cellphone-wiretaps/). ACLU revealed in a trove of documents it had obtained through FOIA requests to more than 200 police departments around the country.
They show a pattern of police tracking cell phone locations and gathering other data like call logs without warrants, using devices that impersonate cell towers(http://redtape.msnbc.msn.com/_news/2012/04/03/10986778-pricey-stingray-gadget-lets-cops-track-cellphones-without-telco-help) to intercept cellular signals, and encouraging officers to refrain from speaking about cell-tracking technology to the public, all detailed in a New York Times story(http://www.nytimes.com/2012/04/01/us/police-tracking-of-cellphones-raises-privacy-fears.html?pagewanted=1&_r=3&partner=rss&emc=rss?).
But at least one document(http://www.scribd.com/doc/87852551/Tucson-Police-Dept-Guide-to-Cell-Tracking) also details the day-to-day business of telecoms' handing over of data to law enforcement, including a breakdown of every major carrier's fees for every sort of data request from targeted wiretaps to so-called "tower dumps" that provide information on every user of certain cell tower."
