“The purpose of the 4th Amendment is to protect against govt. intrusion.”
That’s a penumbra of the Fourth, as the SC said in Roe V Wade, but the Fourth is in the BOR to require the federal government to respect the balance of their power to compel evidence that was enshrined in centuries of the English Common Law: a judge’s warrant.
At the time there was fear they would not.
That balance is clearly upset by cheap, convenient encryption.
I believe, until we come to a new way to balance the rights of suspects and seekers of justice, the Fourth can only survive if encryption is not absolute.
Really? You’re citing penumbras from Roe v Wade? Didn’t you state you were an originalist and loved Scalia?
