Criminal law expert Ken Strutin guides us through the critical facets that comprise the backbone of investigative forensics in the 21st Century – the database. Ken states that of all information gathering techniques, genetic databanking has become the holy grail of prosecutions and the last resort for exonerations. It is both the cause of and solution to many problems in the administration of justice. Thus, DNA forensics highlights the longstanding tension between scientific understanding and legal reasoning. While DNA’s scientific reputation is very near to magic, its forensic applications are subject to the faults and limitations of every kind of evidence offered as proof in a court of law. Ken’s article collects research on the law and science of genetic evidence at the pre-conviction stage. It focuses on the role of DNA in identification, investigation and prosecution of crime, social and privacy issues, and to some degree exculpation or evidence of third party culpability.
