From my experience, many of the problems can be solved by spending time on extended introspection. The problem with authorities is that they often don't have a firsthand experience of the problems itself.
The question here is whether the paper supports the idea that it's worth looking into. Your parent comment suggests that it doesn't (or at least, doesn't strongly).
> many early "stealth" radar detectors were equipped with a radar-detector-detector-detector circuit, which shuts down the main radar receiver when the detector-detector's signal is sensed, thus preventing detection by such equipment.
Well if the hidden camera can be shut down by turning on a hidden camera detector, then the hidden camera detector becomes a hidden camera jammer! All the better.
