In March 2013, activist Bob Offer-Westort sued San Francisco to stop warrantless searches of arrestees’ cell phones. The parties put the case on hold until the U.S. Supreme Court ruling on June 25, 2014, in which the court held that searching an arrestee’s cell phone generally requires a warrant. Yesterday Offer-Westort dismissed his case in exchange for the San Francisco Police Department’s agreement to stop conducting warrantless searches of arrestees’ cell phones.
Even after the Supreme Court ruling, however, law enforcement agencies can still demand that cellphone carriers provide subscriber information, including text messages and caller locations. In 2012, cellphone carriers reported that they responded to 1.3 million such demands from law enforcement agencies in 2011. They turned over records thousands of times per day in response to police emergencies, court orders, law enforcement subpoenas, and other requests. According to a New York Times article dated July 9, 2012:
Under federal law, the carriers said they generally required a search warrant, a court order or a formal subpoena to release information about a subscriber. But in cases that law enforcement officials deem an emergency, a less formal request is often enough.
