I think you are confused about this katy_did, and that is why you think Massei's logic is "garbage." There is nothing wrong with Massei's logic here. Massei never recognized---even for the purpose of discussion---that those six loci "don't match," as you understand what it is not to match. He was only willing to recognize---for the purpose of discussion--- that it hasn't been confirmed that the loci match. But in that case, it would not have been confirmed whether the loci match or not match. That's why those loci are called "disputed" loci.
This is what Machiavelli was trying to say in discussing the lottery ticket mis-analogy. In order for the lottery ticket example to be genuinely parallel to the Raffaele DNA case, some of the numerals on the lottery ticket would have to be missing or obscured in some manner. NOT a case in which some of the numerals on the lottery ticket "don't match" the numerals in the winning number, but a case in which it can't be confirmed whether those "disputed" numerals match, or don't match.
And understood in this way, Massei is right in thinking that more than six loci used in a test is preferable to using only six.....even if some loci remain disputed.
