Its there attitude that winds me up some of em think they are nuts and can speak to you like abit of sh#t but they dont like it when you talk back to em like it or they just come out with ill nick ya what for arguing my point. I have met a couple who are okbut most of em have been knobs.
....If the Police go as far as stopping you it's invariably for one (or more) of these reasons : -
1 - Your driving - which includes behaviour and/or speed.
2 - The state of your car raises a question of safety or legality.
3 - To check your car/driver/insurance etc details. Might be ANPR generated.
In other words, they will 999 times out of 1,000 be totally justified in stopping you. If you are displaying the same sort of attitude towards them as the tone of your posted words, it shouldn't surprise you how you get treated in response.
And so, regarding the "Poor Bloke" subject of this thread, I don't care what he was driving - He'll have been stopped for good reason, of that there can be very little doubt - Even if it was only to inform him a door wasn't properly closed.
