Once upon a time...
In a land not too far away law enforcement officials couldn't eavesdrop on the dastardly plans of criminals unless the could personally overhear what was being said.
It seems to me that those times have simply returned and attempting to remove the privacy that we previously could assume is no longer possible.
Big brother simply needs to understand that (or possibly put Siri/Alexa etc. to listening to every inch of the planet).
