That no doubt expresses the final outcome. But no doubt there were contemporary reports which were deliberaterately ignored because Sinister Cyril was a 'distinguished Liberal politician'. Just as the matters your thread raises were ignored with the excuse of fears of accusations of racism.

As to the grooming gangs, I think a lot of the lack of invetsigation was not just because of fears of accusations of racism but also active misogynism, and other biases.
