The U.S. Supreme Court is set to decide the circumstances in which police may constitutionally search an arrestee’s cell phone without a warrant. On April 29, 2014, the Court heard arguments in two companion cases—Riley v. California and United States v. Wuriewhich occasion the Court to define the scope of the Fourth Amendment in the digital age and strike a balance between an individual’s interest in the privacy of his cell phone contents and law enforcement’s interests in police safety and preservation of evidence. In Riley, police seized David Leon Riley’s smart phone during a traffic stop for an expired licensed plate. Using photos, videos, and call logs obtained through a warrantless search of his phone, along with two hand guns found during a search of his car, police identified Riley as a member of a gang and placed him near the scene of a gang-related shooting that occurred a couple of weeks before his arrest. At trial, although no witness positively identified Riley as a participant in the shooting, the circumstantial evidence from the phone gave the jury enough evidence to convict him of shooting at an occupied vehicle, attempted murder, and assault with a semi-automatic weapon. In Wurie, police arrested Brima Wurie near the scene of a drug transaction and took him to the police station. While there, police seized two cell phones from Wurie. Police observed that one of the cell phones—a flip phone—was repeatedly receiving calls from “my house.” Without a warrant, the officers flipped open the phone, reviewed the call log, and traced the phone number to Wurie’s apartment. Police obtained a warrant to search Wurie’s apartment, where they found crack, marijuana, and other evidence of a drug crime. Wurie was convicted of distribution and possession with intent to distribute crack, and being a felon in possession of a firearm and ammunition.
