For at least six years, law enforcement officials working on a counternarcotics program have had routine access, using subpoenas, to an enormous AT&T database that contains the records of decades of Americans phone calls parallel to but covering a far longer time than the National Security Agencys hotly disputed collection of phone call logs.
The Hemisphere Project, a partnership between federal and local drug officials and AT&T that has not previously been reported, involves an extremely close association between the government and the telecommunications giant.
The government pays AT&T to place its employees in drug-fighting units around the country. Those employees sit alongside Drug Enforcement Administration agents and local detectives and supply them with the phone data from as far back as 1987.
The project comes to light at a time of vigorous public debate over the proper limits on government surveillance and on the relationship between government agencies and communications companies. It offers the most significant look to date at the use of such large-scale data for law enforcement, rather than for national security.
The scale and longevity of the data storage appears to be unmatched by other government programs, including the NSAs gathering of phone call logs under the Patriot Act. The NSA stores the data for nearly all calls in the United States, including phone numbers and time and duration of calls, for five years. Unlike the NSA data, the Hemisphere data include information on the locations of callers.
Hemisphere covers every call that passes through an AT&T switch not just those made by AT&T customers and includes calls dating back 26 years, according to Hemisphere training slides bearing the logo of the White House Office of National Drug Control Policy. Some 4 billion call records are added to the database every day, the slides say.
The slides were given to The New York Times by Drew Hendricks, a peace activist in Port Hadlock, Wash. He said he had received the PowerPoint presentation, which is unclassified but marked Law enforcement sensitive, in response to public information requests to West Coast police agencies.
The program was started in 2007, according to the slides, and has been carried out in great secrecy.
All requestors are instructed to never refer to Hemisphere in any official document, one slide says. A search of the Nexis database found no reference to the program in news reports or congressional hearings.
The Obama administration acknowledged the extraordinary scale of the Hemisphere database and the unusual embedding of AT&T employees in government drug units in three states.
But they said the project, which has proved especially useful in finding criminals who discard cellphones frequently to thwart government tracking, employed routine investigative procedures used in criminal cases for decades and posed no novel privacy issues.
Crucially, they said, the data are stored by AT&T, and not by the government as in the NSA program. The data are queried for phone numbers of interest mainly using what are called administrative subpoenas, those issued not by a grand jury or a judge but by a federal agency, in this case the DEA.
Brian Fallon, a Justice Department spokesman, said in a statement that subpoenaing drug dealers phone records is a bread-and-butter tactic in the course of criminal investigations.
He said that the program was paid for by the DEA and the White House drug policy office but that the cost was not immediately available.
Jameel Jaffer, deputy legal director of the American Civil Liberties Union, said the PowerPoint presentation, evidently updated this year to train AT&T employees for the program, certainly raises profound privacy concerns.
Id speculate that one reason for the secrecy of the program is that it would be very hard to justify it to the public or the courts, he said.
Jaffer said that while the database remained in AT&Ts possession, the integration of government agents into the process means there are serious Fourth Amendment concerns.
Hendricks said the PowerPoint slides came from a major metropolitan police department. He did not want to be more specific.
He filed the public records requests while assisting other activists who have filed a federal lawsuit saying that a civilian intelligence analyst at an Army base near Tacoma spied on anti-war groups.
