Twenty-five years after the attacks of September 11, 2001, John Byrne sits down with Dennis Lormel, who led the FBI's Financial Crimes Program on 9/11 and stood up the Bureau's first Terrorist Financing Operations Section (TFOS) in its aftermath. Dennis shares his firsthand account from inside FBI headquarters that morning, the plan he wrote that night for a centralized financial investigation, and the unprecedented cooperation from banks and government agencies that followed. The conversation covers the warning signs that preceded the attacks, the three-week passage of the PATRIOT Act, the findings of the 9/11 Commission and its terrorist financing monograph, FATF's special recommendations, and the unintended consequences for charities. Dennis closes with an assessment of the threat landscape in 2026 and a call for the proactive, imaginative use of financial intelligence. As this episode marks both the 25th anniversary of 9/11 and the 25th anniversary of counter-terrorist financing, one theme carries throughout: never forget.
