Alison i'm not so sure life is so clear cut for that policy this was a real situation man on bus thrown off for abusing passengers... police called, urgent assistance call by the first police on scene put out to restrain man, ambulance called as they now want to section man. a switched on ambulance crew, who were taking loads of abuse at this stage, though something wasn't "right" did a blood glucose check. very very low. he was having a hypo IV glucagon given, man perfectly civil within minutes. not everybody abusing people are doing it willingly
