"You didn't hear the evidence," Totten says. "The original allegation was that both of these crimes were forcible. But then you have to believe that although she was forcibly raped twice, she continued to come back and have a social relationship with Austin Clem and his family—until he told her that he was going back to his wife and child and would not have a relationship with her. And a week later he was charged. There's always two sides to the story."
The girl was 13 when the first two rapes occurred, which as I understand the law means it doesn't matter whether the sex was consensual or not.
The reasoning above would seem to be more suited for the trial phase, whether he was actually guilty of rape or not, rather than the sentencing phase.
The jury already decided guilt or innocence. The judge isn't supposed to then issue a lenient sentence because he seems to think the convicted isn't "really" guilty of the charge.
The girl should find this guy and shoot him dead. See what a jury thinks about that.
