Interrogation Techniques: A Historically Bad Idea, Scaring Suspects with a Skeleton
In 1930, inventor Helene Shelby patented a bizarre police interrogation device—a life-sized talking skeleton with glowing red eyes, designed to scare criminal suspects into confessing. Hidden cameras and microphones recorded the suspect’s reaction as the skeleton "spoke," creating what Shelby believed would be a foolproof confession tool. Though never used, this eerie interrogation tactic highlights a strange chapter in the history of confessions and coercive police technique

5 Lessons I Wish I Knew Earlier About Interview and Interrogation
If I could go back and talk to my younger self as a new police officer, I'd have some words of advice: Slow down. Listen more. Police work is all about the interview (especially then!). When I started out, I wanted to chase and catch the bad guys. I wanted to clean up the mean streets and I was lucky enough to work in the same Patrol Bureau where I grew up. That meant something to me. If I am able to apprehend sufficient offenders and bring them into the county jail, I will h

AI Stinks! Why Science-Based Interviewing Must Come First
Science-Based Interviewing (SBI) must come before Artificial Intelligence (AI) in policing. Pseudoscientific lie detection and accusatory tactics feed garbage into investigations, and AI will only amplify those errors. Evidence-based SBI—rapport, active listening, open-ended questions—produces reliable, information-rich statements. That’s the data AI can actually use to strengthen cases and build trust in the information age of policing.

Miranda v. Arizona: Why the Fifth Amendment Still Shapes Modern Interrogation
Miranda v. Arizona reshaped modern interrogation by recognizing that custodial questioning creates psychological pressure that can compel statements. The Supreme Court held that the Fifth Amendment requires suspects to be advised of their right to remain silent and to an attorney before custodial interrogation. These protections safeguard voluntary statements, reduce coercion, and preserve the integrity and reliability of evidence obtained during interviews.

Red Teaming in Action: Strengthening Investigative Thinking and Countering Confirmation Bias
Red teaming is a structured approach investigators use to challenge assumptions, counter confirmation bias, and strengthen investigative decision-making. Rather than reinforcing early conclusions, red teaming introduces disciplined skepticism, helping teams test working theories, evaluate evidence more critically, and explore alternative explanations. When applied intentionally, red teaming improves accuracy, reduces risk, and supports more defensible investigative outcomes.
