“One who invites another to his home or office takes a risk that the visitor may not be what he seems, and that the visitor may repeat all he hears and observes when he leaves. But he does not and should not be required to take the risk that what is heard and seen will be transmitted by photograph or recording, or in our modern world, in full living color and hi-fi to the public at large or to any segment of it that the visitor may select.” When Ninth Circuit Judge Shirley M. Hufstedler wrote these words in 1971 about surreptitious recordings made by newsmen, she probably had no idea that a global pandemic would give new meaning to her words.
