Nobody is required to listen to anything, Flaxmeadow, so if you don't want to, don't. "The Rochdale case" is shorthand for the first successful prosecution of a grooming gang in 2012, which Afzal brought to court as chief prosecutor - that's what the fuck he did. It's common knowledge that this is an ongoing problem (and not just in the north of England), but that case was a watershed moment in legal history, and is shorthand for bringing the issue to national attention.
Like I said, if you don't think his expertise has anything to say to you, don't listen; but don't complain if nobody else listens to him and others like him either and nothing gets done, because he is actually advocating for the police and other agencies to pull their fingers out and pro-actively help these girls, and doing so from a place of knowledge of what should have been actioned following the work done 10 years ago.
What are you doing about it?
