Eric Lichtblau reports:
In the first public accounting of its kind, cellphone carriers reported that they responded to a startling 1.3 million demands for subscriber information last year from law enforcement agencies seeking text messages, caller locations and other information in the course of investigations.
AT&T alone now responds to an average of more than 700 requests a day, with about 230 of them regarded as emergencies that do not require the normal court orders and subpoena. That is roughly triple the number it fielded in 2007, the company said. Law enforcement requests of all kinds have been rising among the other carriers as well, with annual increases of between 12 percent and 16 percent in the last five years. Sprint, which did not break down its figures in as much detail as other carriers, led all companies last year in reporting what amounted to at least 1,500 data requests on average a day.
Read more in The New York Times and do consider the statistic concerning how while the number of requests increased significantly, the number of warrants provided to carriers decreased significantly.
