Double Loop Podcast

Glenn and Eric review the new article by Henry Swofford in the Journal of Forensic Identification, The Emerging Paradigm Shift in the Epistemology of Fingerprint Conclusions. They discuss the article, different approaches of reporting, the benefits of these different approaches, and the discussion of this article from the CLPEX message board.

Glenn returns from the ASCLD/LAB conference and brings a report on a workshop put on by Dr. Itiel Dror focused on bias, verification, and other human factors concepts.

Glenn and Eric bring in Carey Hall, Penny Dechant, Heather Conner, and Sean Conner for an extra large Double Loop Podcast that begins talking about presentations to lawyers and testing a new AFIS system. The main topic comes in as Carey and Glenn share experiences from their workshop at the ASCLD conference on managing errors and how to break the news of an error to an examiner.

Glenn and Eric review a couple of email responses. The first addresses AFIS hit frequencies from a listener working at a federal agency that never uses a local search and goes straight to an NGI search. The second email comes from an attorney questioning the idea of a higher threshold for AFIS-generated candidates. Finally, Eric talks about reaction to 'inconclusive with similarities' from a group of attorneys.

Glenn and Eric review the latest article from Matthew B. Thompson and Jason M. Tangen in PLOS One: "The Nature of Expertise in Fingerprint Matching: Experts Can Do a Lot with a Little". These psychology researchers found that experts are more accurate than novices in declaring matches and non-matches.

Glenn and Eric review a recent article by Dr. Tom Busey, Arch Silapiruti, and John Vanderkolk from Law, Probability, and Risk titled "The relation between sensitivity, similar non-matches and database size in fingerprint database searches".

Eric has returned from Virginia and Glenn has returned from Taiwan. This episode they share travel stories including historic neighborhoods and epic sword fights.

Eric is out in Virginia while Glenn is travelling to Taiwan. After some travel stories, Glenn and Eric answer a listener email about technical review. How much influence should the tech reviewer have in changing decisions or documentation?

Eric and Glenn and Carey Hall go throgh a review of the recent Miami-Dade study on accuracy in fingerprint comparisons.

Eric and Glenn are joined by Carey Hall for an interview with Igor Pacheco and Brian Cerchiai, the authors of "Miami-Dade Research Study for the Reliability of the ACE-V Process: Accuracy & Precision in Latent Fingerprint Examinations".

Glenn and Eric first preview some of their upcoming IAI presentations. They then move into discussions of three recent court cases. Eric updates everyone on his "inconclusive with similarities" case, Glenn talks about a QD case where a limited decision was precluded. The last court case is the overturned BC case from a previous episode. Glenn then updates everyone on an upcoming conference in Chicago.

Eric and Glenn continue their discussion of a recent email about how to structure a latent print training program. They review which articles to read, which classes to take, and other topics to focus on.

Glenn and Eric open up the mailbag by first revisiting a previous discussion on ridge tracing. They then move into the larger topic of how to develop a latent print training program.

Glenn asks Eric some more questions about the recent OSAC meetings before Eric tells Glenn about a recent admissibility hearing on a latent print comparison that resulted in an inconclusive decision that still noted similarities between latent and known.

Eric brings back info from the first OSAC meeting and discusses with Glenn upcoming plans for the Friction Ridge Subcommittee.
