Senators Push To Reform Police's Cellphone Tracking Tools

Civil rights lawyers and Democratic senators are pushing for legislation that would limit U.S. law enforcement agencies' ability to buy cellphone tracking tools to follow people's whereabouts, including back years in time, and sometimes without a search warrant. From a report: Concerns about police use of the tool known as "Fog Reveal" raised in an investigation by The Associated Press published earlier this month also surfaced in a Federal Trade Commission hearing three weeks ago. Police agencies have been using the platform to search hundreds of billions of records gathered from 250 million mobile devices, and hoover up people's geolocation data to assemble so-called "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. Panelists and members of the public who took part in the FTC hearing also raised concerns about how data generated by popular apps is used for surveillance purposes, or "in some cases, being used to infer identity and cause direct harm to people in the real world, in the physical world and being repurposed for, as was mentioned earlier, law enforcement and national security purposes," said Stacey Gray, a senior director for U.S. programs for the Future of Privacy Forum.
