EFF – “Americans have the right to expect that digital records of their daily travels—when they left home, where they went, and how long they stayed—is private information, the Electronic Frontier Foundation (EFF) said in an amicus brief filed with the Supreme Court of the United States. Weighing in on one of the most important digital privacy rights cases of the year, EFF is asking the court to hear arguments in Davis v. U.S., a federal criminal case from Florida that examines whether police need a search warrant to obtain historical cell site location information (CSLI). These records show law enforcement which cell phone towers your phone has connected to in the past. In this case, police obtained 67 days of records about defendant Quartavious Davis without a warrant and used them to implicate him in various robberies. In the brief filed Monday, EFF and other advocacy groups argue that the ubiquity of cell phone use in this country—along with a clear increase in law enforcement demands for cell site records and conflicting court rulings about the need for search warrants—means the U.S. Supreme Court should grant review in Davis’s case.”
