I wish I knew how to make it plain to the politicians and law enforcement officials who ask for this why it must not happen.

It would literally be less bad for all display and input devices to have a (password protected, randomly created at time of manufacture) police access mode, than to ban cryptography.

I talked to my local MP about the UK’s Investigatory Powers Act when that came up. I still don’t understand why the UK decided to allow the Welsh Ambulance Service in particular to access, without a warrant, the recent “internet connection records” of everyone except sitting MPs and certain protected professions.
