Uniting forensics, law, and social science in meaningful and relevant ways, Forensic Science and the Administration of Justice is structured around current research on how forensic evidence is being used and how it is impacting the justice system. This unique book—written by nationally known scholars in the field—includes five sections that explore the demand for forensic services, the quality of forensic services, the utility of forensic services, post-conviction forensic issues, and the future role of forensic science in the administration of justice. The authors offer policy-relevant directions for both the criminal justice and forensic fields and demonstrate how the role of the crime laboratory in the American justice system is evolving in concert with technological advances as well as changing demands and competing pressures for laboratory resources.

Since 1985, the adoption of DNA testing for forensic evidence has provided for a significant change in the landscape of forensic science and criminal justice. The individualizing power of DNA testing has placed it into routine use in forensic science and correspondingly has awarded it significant confidence in its power to inform. While professional and public confidence with DNA testing has grown, the technology has revealed problems and issues with other areas of forensic science. Eyewitness identification, serology, and hair analysis are examples of methods that have a diminished level of confidence because DNA testing has revealed problems or comparative limitations (Saks & Koehler, 2005). Hence the criminal ...
