Anyone who's actually paid any attention to the many documented failings of the child protection services in those cases knows the answer to that question is "yes".

The problem with that argument is that, IIRC, there is direct evidence that one reasons that the abuse was covered up was that authorities were afraid of being accused of racism and/or of stirring up ethnic tensions. I don't think that, to accept this, you need believe that CPS is always perfect when this issue is absent.
