The key is that SG is a different school today and this could NOT happen. After failures of previous administrations to examine the abuse, the current head and board are working hard to expose these acts and most importantly to support survivors.
A school that is confidently working to repair prior mistakes is in a much better place than a school that is not examining its past.
