Why are we suddenly so convinced it's not true? Sure, it might not be, but just because she doesn't want it pursued by police doesn't mean she was lying.
No, but it does massively increase the probability that's she's lying, and this shouldn't just be ignored.
How many women don't pursue abuse claims because it's all too difficult?
Raising postulations about the unknowable is irrelevant in any argument. If we can't know the number, then there's no use raising it. It might be a lot closer to zero than you will ever admit, and if we can't prove one way or the other, then you're just wasting everyone's time with useless crap. Grow up eh?
It's two years down the track; it would be traumatic for her to relive it all in detail and the chances are nothing would come of it anyway. Not to mention the unwanted attention she would be receiving from schoolmates, etc. Don't leap to entirely unfounded assumptions.
By accepting her story without question, you are leaping to unfounded assumptions as much as I am. How about getting off the high horse a little and coming back to reality? Reality number one - Kids lie ALL THE TIME for attention. This is a well known fact. I won't let my judgement be affected by unknown facts, especially when they complainant acts suspiciously about it. I will err on the side of caution and assume they are lying. At least that way I won't look stupid when the truth comes out. I might look like a bit of an arsehole now, but that's a small price to pay. I am simply requesting facts, and there's nothing wrong with that. Got any facts to share, or just mere conjecture?
Too many people get hurt in silence already 
Correct! This is exactly why Kyle within his rights to discuss it. Why should a child being raped be taboo? Does this not make the situation worse? Does this not make the child feel even worse for something they aren't even responsible for? Just because we as adults are unable to accept the filth of our behaviour, it does not mean that the sufferring of the innocent should be increased to accommodate this. Two sides to every argument

The more we talk, the better it is for society and for victims. Experts will agree. Idiots who cannot accept the distasteful aspects of humanity will not. Please, don't ruin it for the rest of us. You've done enough damage already.
