Obviously the taking home bit isn't good, but there could be more to this. When we used to go for a "mooch around" hi visibility patrol, dogging sites had rich pickings for drunk and drugged drivers. We had one car investigated with an 80yr old man getting a chewie whilst drinking a bottle of finest red. He had driven there and blew 100+ at the station. Fish in a barrel.
The locals also constantly complain about the police not patrolling dogging sites
