Inside Cartel Conflict and the Reality At The Border | Oscar Hagelsieb | Ep. 435

Oscar Hagelsieb is a Mexican-American law enforcement professional known for his lengthy career in U.S. federal service focused on border security, organized crime and cartel infiltration. He grew up in a tough neighborhood on the outskirts of El Paso, Texas, the son of undocumented immigrant parents. His upbringing gave him firsthand insight into both sides of the border and influenced his decision to pursue a career in federal law enforcement. Hagelsieb began his federal service as a U.S. Border Patrol Agent, where he worked in frontline enforcement along the U.S.–Mexico border. In that role he encountered families and migrants crossing for economic opportunity as well as experienced cartel-linked smuggling activity.  Building on his effectiveness and his deep understanding of local culture and language, Hagelsieb transitioned into undercover work, infiltrating narcotics and human smuggling networks tied to major Mexican drug cartels. His appearance and background were strategic assets in these operations, allowing him to navigate criminal subcultures and gather actionable intelligence that led to prosecutions.  Over time, he rose through the ranks to become the Assistant Special Agent in Charge (ASAC) of the Homeland Security Investigations (HSI) office in El Paso. In this senior leadership position, he oversaw complex investigations into transnational organized crime, cartel logistics, and cross-border smuggling operations, and managed both domestic and international law enforcement efforts.  His work and perspective were featured in the documentary Kingdom of Shadows, which examines the human realities of the drug war and cartel influence along the border, providing rare insight into the lived experience of agents operating within these conflicts.    Today's Sponsors:  Black Rifle Coffee: https://www.blackriflecoffee.com Brunt:  https://www.bruntworkwear.com For a limited time, our listeners get $10 off at BRUNT when you use code "Clearedhot" at checkout.
