Attorneys for the United States "can and must" build a criminal case starting from "reasonable suspicion", through "probable cause", all the way to "beyond reasonable doubt", without violating at any step the Constitutional protections put in place for the express purpose of limiting the government's power to reshape or destroy the society it purportedly serves. We say not to roll your own encryption, but it's one thing to build a lock that is easily picked, and quite another to build one that instantly and silently opens to a key held by a stranger, outside your supervision.
