Commentary on: Thompson WC, Taroni F, Aitken CGG. How the Probability of a False Positive Affects the Value of DNA Evidence. J Forensic Sci 2003;48(1):47-54.
I read with alarm the discussion by Thompson et al., of the significance of DNA evidence in forensic casework. I was struck by the authors' description of a 1995 case in the jurisdiction in which I practice law. The authors state: "In 1995, Cellmark Diagnostics admitted that a similar sample-switch error had caused it to report, incorrectly, that a rape defendant's DNA profile matched DNA found in vaginal aspirate from a rape victim."
