The race issue is a sideshow here - the failure is much more serious than unwillingness to single out one ethnic group.
The police ignored three reports during 2002-06, suggesting either (a) the police were colluding in some sense with the abusers or (b) they couldn’t be bothered protecting these kids. Rather than see a conspiracy where simple mendacity is a good enough explanation, I’d go for (b). These are kids on the margins (the most vulnerable in society as so often derided around these parts). Many of those who reported rapes to the police were not believed. Their parents were ill-equipped to deal with the situation: in two cases fathers tracked down their daughters only to be arrested themselves when they tried to force entry. These kids were let down because they were from certain strata of society and because some of them were ‘difficult’ cases. The real story in this report is about 1400 kids being abandoned by the system.
I’d report them but without much hope that charges would be brought unless one of their victims was prepared to testify.
