I suspect that, rather than sending an s172, the standard procedure would be for the RK to get a knock on his door at 6.00 the next morning.
I think the standard procedure might also be for the RK to say "Oh my gosh officer my car's been stolen, it was on the drive when I went to bed last night!"
And if anything like our local force, they would believe him as well. My wife runs the cemeteries for a local authority and had a call one Sunday morning letting her know that a car had entered the cemetery via a method usually seen in the Dukes of Hazard, smashing through gates, hitting a small hill and clearing the first sets of headstones.
Their CCTV showed it coming down the road, attempting to pull the kerb without slowing, clipping a car and losing control before ending up where it did. Her office cameras showed a man stumble out, lock the door before making off across the road.
Now despite all this and the RK only living around 50 yards from the Cemetery, the police said they had no evidence to refute his claim of the vehicle being stolen. They didn't even consider compiling some awkward questions for him, like why didn't he report it as soon as he realised it was in the middle of the Cemetery opposite him, they just left it as NFA.
