Failed Evidence: Why Law Enforcement Resists Science

Professor David A. Harris of the University of Pittsburgh has published an interesting book entitled Failed Evidence: Why Law Enforcement Resists Science.  His 2012 book looks at problems with the traditional investigative tools in order to understand why wrongful convictions occur.  Harris asks why law enforcement and prosecutors are resistant to changing the techniques they have long relied on, including interrogations and eyewitness identifications. He describes techniques that scientists use to ensure valid results and discusses how they could be applied to forensic examinations and why law enforcement resists applying techniques like blind verification and proficiency testing.

Because this book examines the barriers to adopting new techniques, it is important for anyone working to improve forensic practices. The first chapter can be downloaded for free here. Professor Harris also has a blog where he posts regularly on issues related to forensic evidence, wrongful convictions, and improving police practices.

Attorneys can access training on this topic by following the link to free recorded webinars. The resource page also contains information about how to access current scientific articles on this topic and a link to case law compiled by the North Carolina Conference of District Attorneys. For assistance with understanding medical records and reports, the page has links to two online dictionaries that define abbreviations and medical terminology commonly found in medical records.

Free Online Forensic Training

If you are encountering an issue of forensic science for the first time or if you’re looking for an in-depth training on a specific topic, online forensic trainings are a great way to access the knowledge of national experts from the comfort of your home or office.

I’ve compiled over 100 of these free trainings and put them in the training section the IDS Forensics website. Topics include crime scene investigation, DNA evidence, child abuse, toxicology, working with experts, and many more.  Some of the training organizations require you to register before you take the training, but it just takes a few minutes to sign up.

These online trainings are sponsored by the National Institute of Justice, the National Clearinghouse for Science, Technology & the Law, the Women’s Information Network and local organizations – RTI International, and the UNC School of Government. Check them out!

Texas court upholds exclusion of unreliable scent-lineup evidence

A Texas appeals court affirmed the exclusion of evidence that a dog identified a defendant’s scent in a “scent-lineup” in State v. Dominguez. The trial court found that human scent identification by a canine is not sufficiently reliable to be admitted in evidence in a criminal trial, based on the defendant’s motion to suppress and the testimony of a state and a defense expert. The appeals court affirmed that finding.

It may be worthwhile to take a look at the defendant’s arguments regarding reliability, especially in light the recent North Carolina legislation. Session Law 2011-283 makes several changes to the Rules of Evidence, including new tort limits, but the changes to G.S. 8C-702(a) apply to expert testimony in criminal cases as well. The rule requires for expert testimony, as a condition of admissibility:

(1) The testimony is based upon sufficient facts or data.
(2) The testimony is the product of reliable principles and methods.
(3) The witness has applied the principles and methods reliably to the facts of the case.
