I thought the armchair legal experts had been quiet too long....
Oh well, here we go.
He pleaded guilty to Dangerous driving. Therefore (ST4), why on earth you are gibbering on about a defence to S2, I have no idea. A plea of guilty means that any defence has been waived.
Moving on, the more literate ones of you would have seen this was a 'special reasons hearing'. I suppose I am now going to have to explain it, aren't I?
Special reasons isn't a defence as such, it's where a defendant (any defendant, not just police officers), pleads guilty, but as part of his mitigation gives valid reasons for committing the offence. So, for example, there one of you is, at 2am, on an empty motorway, doing 130mph, but in the car you have a child with an arterial wound who you are taking to Hospital, and the ambulance service have told you that they will be there a week next Tuesday.
You have no defence to speeding, there are no circumstances where you exceed a speed limit and are not guilty as a member of the public. But you can use Special Reasons, in those or similar circumstances.
All he has done, is the same as you would, and the result is likely to have been the same, so (ST4), no, the Police Officer has not been treated any differently to anyone else.
Was his driving S2? Seen the full video have you? No, thought not, so the opinion it is S2 is worth nothing what so ever. The opinion of the training Sgt? Not worth much either to be honest. Most driving trainers I ever met spend exactly no time doing operational driving. In any case, the last one that went to court and said that had a jury disagree with him (Hants officer was acquitted at Guilford Crown Court). I have spend a great deal of time on the wrong side of the road, and been perfectly happy it was safe, if it wasn't, I wouldn't have been there. Driving on the wrong side of a dual carrigeway in a bloody big Landrover, with the outside car, disco and sound system blaring would be no danger at all to anyone looking beyond the end of their bonnet, if you can't see that a long way off and act, then you shouldn't be on the road!
I also refer you to the Magistrates Comments, that she recognized his plea. I suspect that meant, "OK, you pleaded to it, but as I have seen all the evidence (as opposed to the usual internet 'experts', who almost never do!), and if you have gone to trial on it, I would have acquitted you". That option wasn't open to her, but in any case, as a result of the special reasons hearing, she gave the sentence she did. He does though still have a conviction for dangerous driving.
I think St4, this is more about sour grapes because you were not bright enough to look at that big round dial in front of you. He's trained, practiced and in a vehicle that is safe to drive fast in. Were you?
