None whatsoever, actually! Quite apart from being unable to see the screen clearly through tired eyes I don't feel there is a lot I can add!
Incidents like this are often dealt with best by popping down to the police station. Checks can be completed on the index, and the matter resolved one way or another.
IMHO it is entirely plausible that the original poster was misinformed about the write-off category of the car in the first place and it has been returned to the road legitimately.
I will try to have a brief look tomorrow to see if there is anything more that needs looking into.
I cannot see a police officer acting in this way, but I do not think the "impersonation" route is really going anywhere.
