I wasn't about to sit there with this guy and say "well, actually officer you're wrong....". I simply listened to what he said, nodded at the right moments whist looking sheepishly at the footwell. I was caught bang to rights and had no defence whatsoever. So if he'd have told me black was white I would have agreed with him so as not to make the situation any worse. As a result, my overall countenence worked in my favour and I was let go without even a ticking off. I am no friend of the Police as in institution, but I'm not going to provoke them when I'm clearly in the wrong. This one copper wasn't full of the arrogance that I've experienced from others that choose that profession. Made a pleasant change.
+1 well said, no point in winding up someone who is being more than 'fair' in the circumstances.
