“The victims of this Headmaster’s assaults will now be circa 30 – 35 years old, and I just wonder what would be the impact of a few of them walking into a local police station with a view to having proceedings initiated against him.”
The police have recently become more willing to investigate complaints of historic child abuse so it’s quite possible they would take action against the Headmaster Justin referred to. Strictly speaking, they do not need a complaint from the victim(s), anyone who knows what happened can inform them. With luck, that Headmaster could be having his collar felt in the not-too-distant future.
