> I don't think it's nearly that simple. Do you want the same for other techniques? If someone says in good faith that a fingerprint matches and it turns out it was a false positive it should be slander? Shoeprints? DNA? Every technique you listed have problems that prevents them from deciding in good faith if there is a match. Sometimes we can find out probability of match but most of the time even that is out of reach, we just don't know.
