Agree with Toots.
Frankly it would be negligent to not thoroughly investigate this. Even if the parents parted with her willingly, she was living in squalor, being forced to dance/beg for money and possibly used in a sex ring. The videos and photos do not show a happy child to me.
Plus why the need to dye her hair and try to conceal her identity if there was nothing dodgy going on? Why the faking of the bedroom set up?
It's nothing to do with rascism. It's about child abuse being hidden by a closed community. People would be reacting the same way if it was a religious group, gated community or anywhere else that community members share this type of secret.
