Eric Ray and Glenn Langenburg discuss last year's article, Using the PCAST Report to Exclude, Limit, or Minimize Experts by Eric Alexander Vos published in Criminal Justice. We note the extreme bias of the article to exploit the emotions of the judge and jury instead of logic, reason, or data, and we find the serious flaws in many aspects of the paper.

Glenn Langenburg and Eric Ray follow up from last week's discussion of Glenn's recent Daubert hearing with a 2016 article from Jonathan Koehler entitled, Intuitive Error Rate Estimates for the Forensic Sciences. As Glenn suspected, the findings of this article are suspiciously close to the center of the group of choices that participants were presented with. Although there are some larger themes that are interesting, the exact values of the error rate estimates from potential jurors do not match personal experience or even some of the cited prior works.

Glenn Langenburg and Eric Ray return after another hiatus to share travel stories and then to discuss a Daubert hearing that Glenn recently testified in. Short version: having all this new research is way better than when we didn't have it.

Glenn Langenburg and Eric Ray continue their interview with Anja Einseln regarding the merger of ASCLD-LAB and ANAB. Validation of methods and reasons for labs to choose accreditation are some of the many topics covered this time around.

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.

Eric and Glenn tackle a topic that will be a major concern of labs across the country in the next few years, the merger of ASCLD-LAB and ANAB. Some of the changes include the elimination of Latent Print Appendix, the elimination of the Administrative Review requirement, and slight wording changes that may result in huge changes to latent print reports and notes.

Glenn and Eric continue to discuss the 2017 International Conference on Forensic Inference and Statistics. This time Glenn tells about some troubling trends emerging from Illinois where forensic scientists are refusing to answer questions related to the foundational validity of the discipline. He also touches on new work on a different type of Likelihood Ratio approach from Cedric Neumann and colleageus.

Glenn discusses the recent 2017 International Conference on Forensic Inference and Statistics that was held in Minnesota. Specifically, Glenn helped lead a project that looked at how lay people from different backgrounds interpreted different types of forensic results and how those interpretations were used in a courtroom setting.

Glenn and Eric catch up on how things went at the 2017 IAI Educational Conference in Atlanta, Georgia. Glenn covers a panel discussion on the appropriate use of identification, a new workshop of the PCAST calculations, and discussions about what our error rates should be vs. what juries think our error rates should be.

Eric sits down with Amanda, Harres, Vanessa, Jack, and Judith from the Austin Exclusionology class to talk about latent print topics and to ask questions back at the Double Loop Podcast. Glenn later joins Eric in commenting on how the discussion went and to give his own comments on conclusion language, GYRO, and how juries interpret our results.
