Ah, but the elements of this case remain that, the victim is not a child niece, daughter, granddaughter and so on of an adult, but a child that was raped by another child.
With that said, I could think of a lot of reasons why a child would be traumatized and even block out an incident like this happening.
Still not the issue, really.
I do think an assload of what goes on behind the scenes in the legal system takes far place before the court room, so there is much we'll never know...
In any case, I would hate to be that child - after all that time with "hell" in her head, then having her "demons" disregarded...
