I worked with a girl about 10 years ago whose brother had raped her when she was 10 (following years of molestation)
They did not sentence him because he had a scholarship for sports and they didn't want to 'ruin his career'.  FWIW, he is black.
I think if he had been an adult at the time of the crime, it might have been a very different outcome.
The worst part for her was that he was allowed in the family home - and all was forgiven.  She had no interest in doing that and was a mess.  I got her out of the home, but that further stigmatized her 
 
Anyway, I'm not familiar with the stats on this - it would be good to see the numbers.  They are out there, I'm sure 
 
I think - looking at this case - these young girls will face the same problem as my client.  They are trying to 'treat' the boys in the community (though I don't see evidence of it- I don't see a treatment order, but it might exist).  So, the girls will be forced to accept them back into the home/community.  What do the girls get out of this?  They will not feel safe
