You're doubling back to something which makes no sense.Originally you claimed that DNA can be used to prove guilt and then reversed when the science improves.So the case we are talking about is *exactly* that case where DNA is *already being used* In that case you know who the suspect is, you have their DNA.To *prove* that the DNA test was the result of a lab mixup, you then test their sibling, parent, etc. That is the case of which we are speaking.  Not any other. -----Original Message----- From: McDonald, J Douglas <jdmcdona@illinois.edu> To: genealogy-dna@rootsweb.com <genealogy-dna@rootsweb.com> Sent: Thu, Nov 29, 2018 12:38 pm Subject: [DNA] Re: Use of familial search by law enforcement That's absurd. We're talking samples which are unknown ... you know, the unknown rapist. There's no problem with the suspect's DNA once a search warrant for it is issued.
