We have not had this form of privacy for a long time, and I doubt we will regain it unless we would like to do away with DNA evidence altogether.<p>If anything we should be pushing for more precision in the use of DNA samples as evidence. The standards required for identification are incredibly low and result in large numbers of false positives. These poor standards cause harm. The correct use of DNA evidence can clarify crimescene events and has had the power to exonerate many falsely-accused people.
