Opinion of the Court
officer conducted an inventory search of the car. Riley was arrested for possession of concealed and loaded firearms when that search turned up two handguns under the car's hood. See Cal. Penal Code Ann. §§12025(a)(l), 12031(a)(1) (West 2009).
An officer searched Riley incident to the arrest and found items associated with the "Bloods" street gang. He also seized a cell phone from Riley's pants pocket. According to Riley's uncontradicted assertion, the phone was a "smart phone," a cell phone with a broad range of other functions based on advanced computing capability, large storage capacity, and Internet connectivity. The officer accessed information on the phone and noticed that some words (presumably in text messages or a contacts list) were preceded by the letters "CK" — a label that, he believed, stood for "Crip Killers," a slang term for members of the Bloods gang.
At the police station about two hours after the arrest, a detective specializing in gangs further examined the contents of the phone. The detective testified that he "went through" Riley's phone "looking for evidence, because . . . gang members will often video themselves with guns or take pictures of themselves with the guns." App. in No. 13-132, p. 20. Although there was "a lot of stuff" on the phone, particular files that "caught [the detective's] eye" included videos of young men sparring while someone yelled encouragement using the moniker "Blood." Id., at 11-13. The police also found photographs of Riley standing in front of a car they suspected had been involved in a shooting a few weeks earlier.
Riley was ultimately charged, in connection with that earlier shooting, with firing at an occupied vehicle, assault with a semiautomatic firearm, and attempted murder. The State alleged that Riley had committed those crimes for the benefit of a criminal street gang, an aggravating factor that carries an enhanced sentence. Compare Cal.
