Gangs got away with abuse for years in large part because those who were supposed to protect them saw the victims as trash. AND in many (not all) cases the abuse was hushed up in .
It's too simple, and might make future abuse more likely, to see only the cover up as the problem. And those on the fringe who seem to believe that only or mainly Pakistani/muslims commit CSE make the world less safe for all young people.
Of course we should enquure into and understand what happened around the grooming gangs in Rotherham, Rochdale, Oxford etc in order to prevent future abuse and bring people to account where appropriate. Most people are sensible enough to understand an enquiry into grooming gangs is going to report on grooming gangs without saying all CSE is done in this way. (I am an optimist....)
