The Debrief with Eric Immesberger Transistor (https://transistor.fm) https://feeds.transistor.fm/the-debrief-with-eric-immesberger What really happens behind the scenes of the investigations you hear about in the news? Hosted by retired ATF Special Agent Eric Immesberger, The Debrief goes beyond headlines to explore the decisions, psychology, preparation, and lessons behind some of the most dangerous investigations in America. With more than 35 years in law enforcement, Eric spent his career infiltrating violent criminal organizations, posing as a hitman, investigating firearms trafficking, explosives, bank robberies, home invasion crews, and murder-for-hire plots. He also responded to Ground Zero after 9/11 and spent months assisting in the recovery effort. Each episode breaks down real cases, interviews the investigators who lived them, and examines the mindset, tactics, and human behavior that determine success when the stakes are highest. Along the way, Eric shares practical insights anyone can use to improve awareness, decision-making, and personal safety. Whether you’re fascinated by true crime, interested in law enforcement, or simply want to become harder to fool and better prepared, The Debrief gives you the lessons most people never hear.
