Well, we can't say that for certain, can we?
We can say that he wasn't convicted of rape. We can also say that the victim felt raped. And we can say that there was enough evidence of a rape that it was one of the only 1 in 10 reported rape cases that actually make it to court. From that, we could perhaps suggest that there may have been enough evidence to prove in a civil case that on the balance of probabilities he did rape her - though we can't be sure. And since we're unsure on that, perhaps it would be better that we don't stick such a person in charge of children. It's a shame for him, if indeed he did not rape the victim, but it would probably be more of a shame to put someone dangerous in a position of responsibility around children.
