The school hasn’t merely confirmed the allegations’ existence. It attests those inappropriate relationships did indeed happen. That’s far closer to being facts than your “we may never know.” Do you have a pony in this, which accounts for your skewed view?
But in a Metoo era, so many are willing to confess for an organization, just to try to get on the politically correct side. These things are mostly alleged to have happened about 40 years ago.
Just how would people at the school know?
It seems unlikely that there were official records kept, or that the accused confessed to the school.
It could be.
I would like to know more about the alleged details. Maybe more will show up.
I have just seen too many situations where people jump on the bandwagon, only to find that a lot of alleged things really did not happen.
Remember all the day-care satanist sex-cult hysteria of the 80's and 90's? Lots of false testimony there.
