Criminal law expert Ken Strutin’s article addresses how DNA forensics is about information, privacy and the presumption of innocence. It has become the determinant for identification, solving cold cases and exonerating the innocent. Strutin describes that at its core, it is an inestimable library of personal data. Due to the increasingly important role of Personally identifiable information (PII), courts and legislatures have been attempting to balance the interests of the individual in protecting their genetic information with the usefulness and necessity of that same data for criminal investigation. Strutin notes clearly that any DNA or forensic database is a composite of intertwined informational and legal values that pose competing and conflicting questions about the analytics (accuracy, reliability and validity) of the data and the lawfulness (constitutionality) of its gathering. His article collects recent notable decisions and scholarship appearing in the aftermath of Maryland v. King.
