Do you actually think that this officer was parked there in such an obvious place for no real reason.
The car was off the main highway as much as possible and not blocking the pavement, so no real issue to anyone apart from the usual cop haters who comment without knowing the full story.
Yes if there was no reason and it was just gratuitious thats fair enough; but I would suspect that the officer was responding/dealing with a situation. In such circumstanes it is legal to park an emergency vehicke in such a way. The only road signs that emergency vehicles dint have an exemption for are double white line systems and keep left bollards. All actions in contravention if signs however must be safe and justified if questioned.
Contact the police and question the parking if you feel the need to but dont go around with part of a story trying to discredit those that are in the main working hard to keep you safe. Such reports only suggest you have been the wrong side of the law and bear a bitter grudge otherwise.
They might have made a mistake. Best to just stay behind until traffic is slower and closer, then filter. Your life is more important than getting ahead.
