One huge bone of contention at our unit was the sudden introduction of road signs which declared "Police helicopter traffic enforcement", along with some speed camera signs, as if we were routinely airborne on patrol, with "nothing better to do than persecute motorists".
We on the unit saw this as hugely counterproductive with regard to how the general public saw the basic purpose of their police helicopter, not least because it was actually a false declaration of intent. We most certainly did not get airborne with the sole intent of checking the speed of motorists. Not to say we never noticed a speeding vehicle, but it would need to be very blatantly obvious speeding and probably connected to some other criminal misdemeanor.
