I think there's an insurance problem or something with police transporting a patirnt. As part of training in a previous job I spent a day out in a police car. We got called to a mentally ill person who'd smashed a window in his flat. When we arrived he was calm and wanted to go to the local mental health respite hospital as he knew he was having an episode and it would be safer for him. The landlord didn't want to press charges so he was not to be arrested. He had no money for a taxi and couldn't get any money out. The police were not allowed to transport him as he was not arrested. They didn't want to call an ambulance as its not an emergency and they would probably have to take him to A&E not the place he needed to go. Eventailly the police officer managed to get authorisation to take him, but it had to go up to the highest officer on duty that night. All because they're not insured to carry him or something. Was a total waste of hanging around to get this permission. If he'd been left he knew we'd probably be out there again in a few hours..
