Local law enforcement agencies from suburban Southern California to rural North Carolina have been using an obscure cellphone tracking tool, at times without search warrants, that gives them the power to follow people’s movements months back in time, according to public records and internal emails obtained by The Associated Press.

Police have used “Fog Reveal” to search hundreds of billions of records from 250 million mobile devices, and harnessed the data to create location analyses known among law enforcement as “patterns of life,” according to thousands of pages of records about the company.

Sold by Virginia-based Fog Data Science LLC, Fog Reveal has been used since at least 2018 in criminal investigations ranging from the murder of a nurse in Arkansas to tracing the movements of a potential participant in the Jan. 6 insurrection at the Capitol. The tool is rarely, if ever, mentioned in court records, something that defense attorneys say makes it harder for them to properly defend their clients in cases in which the technology was used.

[...] “It’s sort of a mass surveillance program on a budget,” said Bennett Cyphers [eff.org], a special adviser at the Electronic Frontier Foundation, a digital privacy rights advocacy group.

[...] The documents and emails were obtained by EFF through Freedom of Information Act requests. The group shared the files with The AP, which independently found that Fog sold its software in about 40 contracts to nearly two dozen agencies, according to GovSpend, a company that keeps tabs on government spending. The records and AP’s reporting provide the first public account of the extensive use of Fog Reveal by local police, according to analysts and legal experts who scrutinize such technologies.
