Why wasn't this headline at the time, why isn't it headline news now?

This piece from the excellent Craig http://isthebbcbiased.blogspot.com/2018/11/had-you-heard-of-this.html should be a must read for every politician, journalist and citizen of the UK.

Here's the key part 

'Nazir Afzal:..." back in 2008 the Home Office sent a circular to all police forces in the country saying "as far as these young girls who are being exploited in towns and cities, we believe that they've made an informed choice about their sexual behaviour and, therefore, it's not for you police officers to get involved in". That's the landscape coming from the top down in 2008. Rest assured, all agencies are going to listen to it. It only changed because of the work we did and the work the Times newspaper did in 2010-11. The fact that we were able to bring the prosecution in Rochdale led to this investigation in West Yorkshire opening...it  only opened in 2013. And the series of prosecutions that have followed indicate to me that the agencies are getting it right now but the reality, of course, is that we've lost a generation of young girls who have been left behind and abused."

So if Mr Afzal, who knows as much about this as anyone, is correct, then why hasn't this been picked up on by mainstream journalists? Why didn't this PM interview spark a nationwide clamour to investigate that 2008 Home Office circular, and the behaviour of the Home Office under Gordon Brown's government? Surely, if, as Mr Afzal alleges, it played a part in keeping the grooming gangs operating with impunity for a few years more then it's a massive scandal, isn't it?'

Seems like a scandal to me but the Labour Party's propaganda arm, the BBC, isn't going to in any way ask awkward questions to the Labour Party or indeed of any parts of the Muslim community.
