“If the police arrest you, do they need a warrant to rifle through your cellphone? Courts have been split on the question. Last week the Obama administration asked the Supreme Court to resolve the issue and rule that the Fourth Amendment allows warrantless cellphone searches. But as the storage capacity of cellphones rises, that position could become harder to defend. Our smart phones increasingly contain everything about our digital lives: our e-mails, text messages, photographs, browser histories and more. It would be troubling if the police had the power to get all that information with no warrant merely by arresting a suspect.”
