Interesting point. Where does "obvious" recording stop and "covert" recording begin? Can you break the law by simply having a high-sensitivity microphone? And

Interesting point. Where does "obvious" recording stop and "covert" recording begin? Can you break the law by simply having a high-sensitivity microphone? And note the recent case of a man being charged with indecency for being nude in his own kitchen - but visible from a public place. So if anything conceivably visible/audible from a public place is now classed as "public", a laser mike on a window, or a zoom camera recording mouth movements (which can be reliably decoded into speech) might arguably be permissible.
