It is not the psychiatrists who figure out a potential for violence. It is instead staff who spend time with the patient, watch their behavior and document it. It is generally psychologists who do the report writing after participating in a group of mental health professionals of different types giving input. The symptoms Santiago displayed to the FBI are not indicative of PTSD. They would indicate a psychosis, most likely Schizophrenia. Of course any trauma would exacerbate the development and expression of it. New research shows mental illness is most likely secondary to childhood trauma in most cases. We have no mental health information, the state is protecting the facility which let Santiago go after four days. They will protect the APD, probably hiring their exonerator Greg Russell to write a report. I do agree that psych meds are health harming, in most cases the patient should not have to take them. A tiny percentage are a danger to others. Meds vs prison, which is worse.
