Normally I would agree with you, but the ability to pull this kind of thing off hinges on there being enough shadows that the Eye doesn't look at for prolonged periods of time. And the overall trajectory of technological advance lately is such that those shadows are rapidly shrinking. First it was the street cameras (and UK is already one of the most enthusiastic adopters in the world). And now comes AI which can automatically sift through all the mined data, performing sentiment analysis etc. I feel that the time will come pretty soon when "a guy" will need to be so adept at concealing the tracks in order to avoid detection that most people wouldn't have access to one.
