I would just add that what paragraph 6(1)(d) talks about cannot be excluded. That's where the difference comes. The data bank advisory committee, as you've heard, has some international experts on this.
My understanding--and every time I talk about the science, Dr. Fourney winces--is that each loci has two, so there are 26, and when you get around 18 or 20, the geneticists will tell you those are going to be brothers or sisters, that sort of thing. But if one or two of them are off, they're simply not allowed because that person has been excluded. So they could not tell the police they're probably looking for the brother of Joe Blow.
