I echo TTH's sentiments, having read the thread on ARRSE. The ball is firmly in the Headmaster's court and he is the only one now who can prevent this from exploding into something much bigger with all the bad publicity for the School and education system. Indications are that the head is handling this well.
Mazur has apparently handled the situation in a very mature fashion and is a great advert for his generation. Well done from the light blue!
