The law was tested on this point a couple of years ago and the Police
and CPS lost. The radar detector is used to detect the signal is there,
not to listen to the contents of that signal. There was a landmark
ruling on this and the judge rules that is was legal to use one of these
detectors.

I didn't know this. I suppose it fits in with the modern ruling that speed
cameras should be made highly visible so they act as a deterrent, on the
lines that it's better to slow cars down than simply to penalise the drivers
after the event for speeding.
