However I also agree that charges like this demand a high standard of evidence, and the testimony of only the 7-year-old girl should be taken with a grain of salt.
If there is physical evidence that matches the girl's testimony, then that helps substantiate the charges. But (even inadvertently) false memories are easy to implant in children.
This should not get bogged down in arguments about the truthfulness of little children, women not being believed, black versus white, when the issue should be, did the alleged incident really happen or not.
I tend to doubt it really happened since the news article would (OK, "should") have mentioned physical or circumstantial evidence if that was part of the case.
I bet this didn't happen, and will get quietly dropped. The Board Member would have to move out of the state, in any case.
