But surely it can't be long before someone decides to sue because they have been injured while mentally incapacitated and they argue that the NHS should have sedated/restrained them before they hurt themselves further? I'm not suggesting they should sue, just that management maybe should be taking into account the possibility that at some point someone might? Could they argue that while they were temporarily a 'vulnerable adult' appropriate treatment to prevent further harm was witheld? or is there some protection under the law to prevent that?
