Modern policing has changed a lot since I was in uniform (and, without doubt, it has been required to change), but the requirement to assess any situation and deal with it in the most efficient manner has not.
So, unless there is absolutely no alternative to reporting any matter/issuing a notice or the person concerned is giving some measure of grief then, in the vast majority of cases, advice, a warning or the opportunity to rectify faults (in the case of vehicle detections) will all go a very long way to keep the essential compact between the police and the public alive and well.
Yes, it does appear to be a bit harsh, sadly, but given the performance targets issued by the gutless cadre of middle management which seems to be infesting the police at the moment or the over-zealous individual who delights in sticking it to someone (have known a few of that sort), I’m not at all surprised that such incidents occur.
I've said this many times - keep oppsing about with the people you depend on to make the system work i.e. the public, and you'll eventually get bitten by them and when you are, can you really complain?
