Stephen B. Mercer Appears on CBS’ Sixty Minutes to Discuss DNA Issues In July, 2007, Stephen B. Mercer was a featured guest on a CBS News Sixty Minutes report entitled “A Not so Perfect Match,” an examination of the newly-emerging technique of familial searching of forensic DNA databases.
Forensic familial searching involves the use of partial, “near miss” matches of crime scene DNA samples with the DNA databank profiles of convicted criminals, thereby implicating relatives not included in the databanks because they were never convicted of committing any crimes. >> more
Genetic Surveillance for All
What if the FBI put the family of everyone who has ever been convicted or arrested into a giant DNA database?

Stephen Mercer was a guest on the Kojo Nmadi Show to discuss Forensic Science, Technology and the Courts
They're the building blocks of our criminal justice system: little pieces of evidence like fingerprints, hair and DNA samples. But a new report cites serious flaws in how this evidence is most commonly collected, analyzed and interpreted by law enforcers. Tech Tuesday explores the capabilities and limitations of forensic science, and how new technologies are likely to affect the rule of law. Hear the show at:

DNA Testing Expands to Lesser Crimes
DNA testing in the county is expanding from killings and rapes to less violent robberies, burglaries and drug deals. Prosecutors say this will lead to quicker convictions because defendants will cave and plead guilty. Defense lawyers worry that as more DNA samples are pushed through the county's crime lab, it will boost the odds of false matches. Dan Morse of the Washington Post interviews Stephen Mercer about the potential for the gold standard of forensic science to be undermined. Click here to view at Washington Post
DNA-Sample Collection Under the DNA Fingerprint Act of 2005
The Department of Justice has issued proposed regulations to implement the expansion of DNA collection to include federal arrestees and non-United States detainees under the DNA-Sample Collection Under the DNA Fingerprint Act of 2005 and the Adam Walsh Child Protection and Safety Act of 2006. On May 19, 2008, Stephen B. Mercer, Esq., and William G. McLain, Esq., submitted public comments on FR Doc # E8-08339, in which they requested clarification of the amount of force that agencies are permitted to use for the purpose of extracting DNA from persons who do not voluntarily surrender their DNA. Further, they requested that the regulations require that counsel be provided upon request before any DNA collection be permitted. Read more.
Familial Searching of DNA Databases: In a comprehensive article, the Washington Post reports on the emerging trend of searching DNA databases to identify family members as possible suspects, and the arguments for and against such an investigative technique. See Ellen Nakashima, From DNA of Family, a Tool to Make Arrests, The Washington Post (April 20, 2008). Stephen B. Mercer is quoted regarding the dual privacy concerns of persons becoming genetic informants on their family members, and innocent family members themselves coming under lifelong genetic surveillance.
