Episode 169 – Simon Cole Interview

Simon Cole Interview

Simon Cole Interview

Eric Ray sits down for an interview with Simon Cole from the University of California Irvine. Simon explains how he first became interested in forensics and in latent print comparisons in general, and then outlines the history of his criticisms of the field. Glenn Langenburg later joins Eric for a review of the interview and some of Glenn’s perspectives on how Simon’s criticisms and the latent print response have both evolved over time.

Episode 165 – Categorical vs. Probabilistic

Categorical vs. Probabilistic

Categorical vs. Probabilistic

Glenn Langenburg and Eric Ray tackle two articles in one fantastic episode. First, “Lay Understanding of ‘Identification’: How Jurors Interpret Forensic Identification Testimony” by Henry Swofford and Jessica Cino from the Journal of Forensic Identification. Secondly, the guys tackle a paper from the Journal of Forensic Sciences, “Comparing Categorical and Probabilistic Fingerprint Evidence” by Brandon Garrett, et al. The big question is: should we say “identification” or should we express the same conclusion in a probabilistic manner?

Anja Einseln Interview – Part 1

Glenn Langenburg and Eric Ray first revisit a couple of additional aspects of our previous discussion on defense interviews in Illinois before diving into the deep end of accreditation. Anja Einseln joins the Double Loop Podcast as our guest expert on ASCLD/LAB, ANAB, and all things accreditation. In the first half we talk about some of the changes that will be coming with the recent merger of ASCLD/LAB and ANAB and what it means for latent print units in accredited labs.

“It’s an acknowledgement even in Section A of 5.10.1.1 that you may just do a partial analysis on the submitted items. You may not analyze some things because again once you’ve identified that Jane Brown’s fingerprints were found on at least one of the beer bottles then the investigator has the information that they need. So again, the intent is moving away from the how and focusing on the what. So the what is the lab has to have a procedure and you need to decide at a minimum what’s going to be reported for all the items received so in some instances it might be processed but not evaluated.”

Episode 131 – Weight of Evidence

Weight of Evidence

Weight of Evidence

Glenn and Eric listened to the online recordings of the NIST Technical Colloquium Quantifying the Weight of Forensic Evidence. The presentations brought up lots of questions on how forensic scientists should be presenting evidence to juries and the court. Can juries understand complicated models or even nuanced levels of association? Is the search for a mathematical model to express the weight of evidence just a fool’s errand?
