He was arrested because the police resented that he did not immediately 'respect my authoritah'. He was not interfering with paramedics. He was a safe distance away.
He got put on psychiatric hold by the police as retribution for insisting it is reasonable for him to have the right to see a doctor for medical treatment.
Medical treatment which was only required because the police physically assaulted him.
It's very hard to imagine a retelling of his story which doesn't involve substantial police misconduct.
