I think this maps onto schools, classrooms too. Often the disruptive behaviour is a sign to everyone else: ‘what are you going to do about it?’ If nobody does anything (worse, if the teacher doesn’t) then the disruptor gets a status boost. ‘No one f*cks with me.’ This is, of course, terrifying for other students in the room, who want to avoid the penalty of being the one who calls them out. So, most decline. Which is why it is crucial the adult in the room occupies the role of law giver and adjudicator, not just advocate or counsellor.
