I was a bit shocked 20 years ago walking through Livingston police station, they had a wall of screens of live feeds from all over the town. You kind of expect that in a city-centre especially now, but I hadn't ever spotted a single camera in that small town.
The top cop there had a chat with me about them trying to bribe a student activist to spy on their student politics, the student of course exposed them in the media, and the cops attitude was telling, "If we can do it we will do it". No regard for morality or legality, just give them a tool and they'll use it to beat you with.
A very decent young man emerged from their training and complained to me bitterly about human rights legislation stopping him doing his job. And expected my sympathy.
