Right, but if there is a system to access your machine without your usual creds and that system gets hacked, that's backdoor access. You can say - the system for US intelligence is like 'another account' or a 'second root' and is known to Google and so it is not a backdoor - but is that really within the spirit of the discussion?

If you didn't understand that this was a separate system with separate access data, specifically for law enforcement requests, then that should clear it up.

If not we can go over semantics a ton but I don't like those games (everyone loses [time]).
