Devil's Advocate — in the entire history of US law, if police can convince a judge that they have a good enough reason, judge can give the cops permission to break into your house, your bedroom, your diary, your safety deposit box, the safe you buried in your shed ... a judge always had the choice to decide whether or not cops get to invade your privacy.<p>For the first time, ever, strong encryption changes that paradigm. Personally, I'm still in favor of it, but it really is a very fundamental game-changer.
