………AT&T is profiteer in support of the modern surveillance state.
Hemisphere is a secretive program run by AT&T that searches trillions of call records and analyzes cellular data to determine where a target is located, with whom he speaks, and potentially why.
“Merritt was in a position to access the cellular telephone tower northeast of the McStay family gravesite on February 6th, 2010, two days after the family disappeared,” an affidavit for his girlfriend’s call records reports Hemisphere finding (PDF). Merritt was arrested almost a year to the date after the McStay family’s remains were discovered, and is awaiting trial for the murders.
In 2013, Hemisphere was revealed by The New York Times and described only within a Powerpoint presentation made by the Drug Enforcement Administration. The Times described it as a “partnership” between AT&T and the U.S. government; the Justice Department said it was an essential, and prudently deployed, counter-narcotics tool.
However, AT&T’s own documentation—reported here by The Daily Beast for the first time—shows Hemisphere was used far beyond the war on drugs to include everything from investigations of homicide to Medicaid fraud.
Hemisphere isn’t a “partnership” but rather a product AT&T developed, marketed, and sold at a cost of millions of dollars per year to taxpayers. No warrant is required to make use of the company’s massive trove of data, according to AT&T documents, only a promise from law enforcement to not disclose Hemisphere if an investigation using it becomes public.
While telecommunications companies are legally obligated to hand over records, AT&T appears to have gone much further to make the enterprise profitable, according to ACLU technology policy analyst Christopher Soghoian.
“Companies have to give this data to law enforcement upon request, if they have it. AT&T doesn’t have to data-mine its database to help police come up with new numbers to investigate,” Soghoian said.
AT&T has a unique power to extract information from its metadata because it retains so much of it. The company owns more than three-quarters of U.S. landline switches, and the second largest share of the nation’s wireless infrastructure and cellphone towers, behind Verizon. AT&T retains its cell tower data going back to July 2008, longer than other providers. Verizon holds records for a year and Sprint for 18 months, according to a 2011 retention schedule obtained by The Daily Beast.
The disclosure of Hemisphere was not the first time AT&T has been caught working with law enforcement above and beyond what the law requires.
Once AT&T provides a lead through Hemisphere, then investigators use routine police work, like getting a court order for a wiretap or following a suspect around, to provide the same evidence for the purpose of prosecution. This is known as “parallel construction.”
“This document here is striking,” Schwartz told The Daily Beast. “I’ve seen documents produced by the government regarding Hemisphere, but this is the first time I’ve seen an AT&T document which requires parallel construction in a service to government. It’s very troubling and not the way law enforcement should work in this country.”
Sheriff and police departments pay from $100,000 to upward of $1 million a year or more for Hemisphere access. Harris County, Texas, home to Houston, made its inaugural payment to AT&T of $77,924 in 2007, according to a contract reviewed by The Daily Beast. Four years later, the county’s Hemisphere bill had increased more than tenfold to $940,000.
Increasing the data that they can collect through mergers and acquisitions is not good for the rest of us.
