A Superior Court in Ventura County, California, ruled that police in that state can search the contents of an arrested person's cell phone. The ruling allows police in California to access any data stored on an arrestee's phone: photos, address book, Web browsing history, data stored in apps (including social media apps), voicemail messages, search history, chat logs, and more. According to Catherine Crump of the American Civil Liberties Union, "The police can ask you to unlock the phone -- which many people will do -- but they almost certainly cannot compel you to unlock your phone without the involvement of a judge," she said.
