The nation's wireless carriers reported a sharp increase in demand for data from law enforcement agencies in 2011, reports the New York Times.
The carriers received 1.3 million demands for subscriber information from law enforcement during the year that included text messages, caller locations, and other data during investigations.
The carriers frequently rejected requests they considered legally questionable or unjustified. The data indicates that agencies are shifting away from wiretaps to other forms of cell tracking, reports The Times.
