We should be focusing on why thousands of vulnerable girls were blamed for being victimised. These men preyed on them because they could, they acted with impunity for decades.
The victims were let down by every agency put in place to protect them: the care system, the police and social workers. We need to know what changes are being put in place to make sure this doesn't happen again.
I think that you should be prosecuted if you don't act on child abuse and I think that these agencies need to be overhauled if they're not effectively protecting children. Focusing on the ethnicity of the perpetrators, isn't particularly helpful.
