The President’s DNA Initiative has released Principles of Forensic DNA for Officers of the Court, a CD-ROM that addresses the use of DNA in judicial proceedings. This resource is designed for prosecutors, defense attorneys, and judges, and provides a simple overview of DNA technologies and the issues that arise when DNA evidence is presented in court. The topics are covered in short paragraphs accompanied by illustrations, and links to other resources are included. Some of the areas covered by the CD-ROM include the biology of DNA, DNA laboratories and quality assurance in testing and understanding lab reports, forensic databases, victim issues, presentation of DNA evidence at trial, and postconviction DNA cases. This resource was produced by the National Institute of Justice as part of President Bush’s initative to ensure that the science of forensic DNA reaches its full potential in solving crimes, protecting the innocent, and identifying missing persons. Copies of the CD-ROM are available through the National Criminal Justice Reference Service at https://www.ncjrs.gov/ or by calling 1-800-851-3420 (those calling should ask for NCJ 212399). An online version of this resource is available at http://www.dna.gov/training/otc/. See Resources and Innocence.
