Telecommunications giant AT&T is spying on Americans for profit and helped law enforcement agencies investigate everything from the so-called war on drugs to Medicaid fraud—all at taxpayers’ expense, according to new reporting by The Daily Beast.

The program, known as Project Hemisphere, allowed state and local agencies to conduct warrantless searches of trillions of call records and other cellular data—such as “where a target is located, with whom he speaks, and potentially why”—for a massive range of investigations, the Beast‘s Kenneth Lipp reports. In one case examined by the news outlet, a sheriff’s office in Victorville, California used Hemisphere to track down a homicide suspect.

Hemisphere was first revealed by the New York Times in 2013, but was described at the time as a “partnership” between AT&T and drug enforcement agencies used in counter-narcotics operations.

Neither, it turns out, is entirely true.

Lipp writes:

The details were revealed as AT&T seeks to buy out Time Warner in a mega-merger that media watchdogs are warning would create “dangerous concentrations of political and economic power.”

Evan Greer, campaign director at the digital rights group Fight for the Future, said Tuesday, “The for-profit spying program that these documents detail is more terrifying than the illegal [National Security Agency] surveillance programs that Edward Snowden exposed. Far beyond the NSA and FBI, these tools are accessible to a wide range of law enforcement officers including local police, without a warrant, as long as they pay up.”
