This is a good point and well taken, Ursus. This happens to be a great example, because one of the MBA investigation findings is that MBA failed to report a child rape. This is an enormous problem, and it is a crime.
We still don't know if the child reported a rape that occurred prior to her enrollment at MBA, or if she was raped by another attendee or staff member right on the premises. In either case, MBA failed to protect this child. The staff to whom this was reported and all staff subsequently informed of it and the decision maker who judged this should not be reported all should be in prison. It's plain and simple.
If this occurred at a public school, there is no way it would have escaped detction by the proper authorities. In this case, the child was prevented from telling the authorities. That would never happen at a public school.
