I've met Grampian police a few times. Mostly involving photography. I have a current plan to convert a 1/24 scale truck model into a skip lorry for which no commercial model exists, I have built flatbeds, box vans and cattle trucks along the same lines so I photograph a lot of trucks. I also build models of other things and rarely stick to the picture on the box.
Once I met them when reporting an attempted scam and once about a fatal accident I was neither involved in nor the cause of, but was there to support a witness. They were always courteous and careful with their words. I have never found anything in their manner to complain about. They have never arrested me and have never taken my DNA. Oh, and I have never permitted them to delete a single photograph on the grounds - which they agree with - that if there was a crime committed and they deleted the photo, they would be guilty of destroying evidence. So, no problem. Not even when photographing ships at the docks. We get some really impressive ones here. In recent encounters they even seemed wary of me which I thought odd, considering they are almost all twice my size and five times my level of fitness.
So I don't think the police are behind this. Someone higher up is running the show here. The police are being fed dodgy information from someone higher up the chain. The police are, in fact, being as duped as the rest of us by someone.
Someone with an awful lot of influence.
