The Supreme Court has come down on the side of privacy and ruled that police can't look through your cellphone without a warrant.
The court's decision to keep your cellphone private is particularly important. The ability to carry information on your person means that you'll have more information on-hand at all times.
Police have used the photo albums and text histories on cellphones to make cases without cause or evidence. Chief Justice John Roberts just put a stop to that.
Modern cell phones are not just another technological convenience. With all they contain and all that they may reveal, they hold for many Americans "the privacies of life," Boyd, supra, at 630. The fact that technology now allows an individual to carry such information in his hand does not make the information any less worthy of the protection for which the Founders fought. Our answer to the question of what the police must do before searching a cell phone seized incident to an arrest is accordingly simple - get a warrant.
The constitutional right to privacy now extends to our cellphones.
Remember, though, not everybody needs to get inside your cellphone to spy on you. Here's how to protect yourself from the NSA.
