What do we actually know and can agree on about this issue?
Well, firstly, that it's wide-spread, that it's been going on a very long time, and that (forget the "accused" bit in the OP) the "police, schools, councils and social services" have repeatedly failed to properly investigate the abuse.
Can anyone explain this almost universal long-term cover-up? People on the left usual profess higher moral standards than the rest of us, and yet most of the local councils where the abuse has been most rife have been Labour run, most people in the social services are left-leaning, as are most members of the teachers' unions. On the other hand the police force has often been portrayed as "systemically" racist, in which case accusations of the gang-rape of under-age girls by Pakistanis would have played directly into the hands of some coppers, wouldn't it?
And yet the abuse was allowed to to continue. As one poster lamented: "Failures of almost unbelievable scale, so many let down".
I'm trying to get myself into the minds of the many hundreds (perhaps thousands) of people who had to remain silent in order for these crimes to continue with impunity for so long. I cannot imagine myself being in the know and not speaking out. Nor can I imagine what pressures could be put on me, by whom and for what reason to keep me quiet.
One poster wrote "All abusers should be uncovered and given lengthy prison sentences......... regardless of colour or creed". Yes, so they should. Can that poster think of a good reason why that didn't happen?
