I'm quoting this one but I could have picked any of the comments! There has been a lot of publicity on this issue via Charles Spencer and his recent book on boarding, and the sexual abuse inflicted upon him, also via the BBC presenter Nicky Campbell, I think his was Fettes College, and some kind of sexual abuse inflicted upon him and others... they have been trying to extradite the accused who is now living in South Africa.
There is a kind of omertà - a code of silence - on this issue.
It is interesting given the number of ex-public school types who go on to attain power in Westminster, Boris Johnson most famously. If they haven't been abused themselves, or been the abuser, they must have learned how to turn a blind eye to those unlucky enough to have had it done to them, a classic thing of the right hand not knowing what the left hand is doing. You get this in State organisations a lot, say, in the Church or the Police, or local Councils, why, it's on an AIBU thread about the state of the NHS currently active.
I went to a nominally public school but not like that, I found when I went to Bristol Uni there were a lot of these types who took to uni like a duck to water, in particular the being away from home aspect, because they'd already had that baptism of fire at the age of 8 or 10, whereas other normal kids will have found themselves away from their family, their home, their home town etc for the very first time at the age of 18, and even if you've been looking forward to it, it can knock you back a bit.
