I have no opinion on this case at all. I will say the in the case of a father sexually abusing his daughter, almost always there is no evidence until the child talks. By that time any evidence is long gone.
It's not really evidence in the sense of "the jury is there at the crime scene". Children are very susceptible to adult influence, including the influence of crusading adult prosecutors and child psychologists looking to make the headlines, which bring the promise of both fame and fortune. That's not even factoring in the reality that children can be remarkably amoral and downright wicked, which is why they have featured as key players in large scale genocides like the Cambodian Holocaust and the Sierra Leone massacres. Sticking it to an adult via a child abuse accusation is child's play compared to the atrocities mentioned, and eminently plausible.
