Dear Ms. Dallaglio," in a dangerous situation", as you describe in your story, what your husband, his colleague, and the other women helped themselves AND the man in some type of psychiatric distress. The intervention was escaping to the other car giving space to the person in distress. I share this from three perspectives; a SPED professional whose last cohort was 18-24 year olds, the teacher who provided refuge for a colleague and her students who had to immediately escape a similiar situation, and just last month on an LA METRO train was among a train car of travelers who froze-in-place while a tall ( 6ft.plus) blond young and athletic man ranted to a 'group' of invisible friends, tore off one outer layer of clothes, and jumped on-and-off our car until we reached our final destination.
