On January 6th, a mob stormed the US Capitol to try to stop the certification of the presidential election results. Many of the insurrectionists will be tracked down and charged with crimes, in part, because their cell phone placed them in the Capitol Building during the attack. The case of Carpenter v. United States is the closest the Supreme Court has come to weighing in on the matter of historical cell phone data, but the decision didn’t not offer an opinion on law enforcement’s use of a location specific cell phone tower data dump without an individual suspect in mind. This brings up questions about the way warrants usually work under the Fourth Amendment.
