“The court released a landmark decision in the case of Riley vs. California, forbidding warrantless police searches of the contents of arrestees’ cell phones. The ruling opinion notes that cell phones have in fact become tiny computers in Americans’ pockets teeming with highly private data, and that gaining access to them is now fundamentally different from rifling through someone’s pockets or purse. The court also rejected prosecutors’ notion that the ability to remotely wipe or lock a phone required police to search the devices immediately upon arrest before evidence could be destroyed–an ironic argument given that police pressed for those same remote ‘kill switch’ abilities.”
