Moot?!  Please.  In 2018 Apple gets handed a national security letter with a demand to backdoor all deployed iOS devices, with which they comply.  Users see a routine update (maybe even with some conveniently timed security fixes included too!), and... key in their PIN.  Everyone is now backdoored.  Not the specific situation you were thinking of?  Welcome to the world of security design: holes are everywhere and plugging them piecewise doesn&#x27;t work if the problem is fundamentally intractable.  Your theory would protect the San Bernardino shooters, but not you or me or anyone else.<p>Why do people (smart people, even!) continue to insist that this problem can be solved by technical measures?  <i>This problem cannot be solved technically.</i>  Stop it.  Please.  This misinformation is hurting all of us.<p>If you want snoop-proof encryption then the user needs to manage the keys herself, which I believe was MJG&#x27;s point in that blog post.  (And even then you&#x27;re trusting the hardware itself not to have a backdoor to pull off the pass phrase, etc...).
