From busting drug lords to leading the Pentagon task force charged with bringing the 9/11 terrorists to justice, Mark Fallon has spent his career on the front lines of U.S. national security.

Former NCIS Special Agent in Charge Mark Fallon is a national security consultant, scholar, and expert in counterintelligence and counterterrorism who’s been involved in some of the most significant terrorism investigations in U.S. history. Mark served more than thirty years in government—twenty-seven with the NCIS and two as a Senior Executive within the Department of Homeland Security. He received numerous awards and medals for his service, including the Department of Defense Counterintelligence Award for Outstanding Achievement and the U.S. Secret Service Director Honors Award.

In the wake of the 9/11 terrorist attacks, Mark was appointed Deputy Commander and Special Agent in Charge of the Pentagon task force, responsible for investigating terrorists for possible trials before military commissions. His critically acclaimed book, Unjustifiable Means: The Inside Story of How the CIA, Pentagon, and U.S. Government Conspired to Torture (Regan Arts) offers a gripping account of the leadership challenges he faced while trying to bring terrorists to justice — without compromising his oath to protect and defend the Constitution.

As an NCIS Special Agent, Mark operated undercover in some of the most dangerous places in the world

Mark opens up about what it takes to lead under pressure, the duty to disobey an unlawful order, and why interrogators make the best first dates. He shares leadership lessons that extend far beyond national security—tools for navigating crisis, conflict, and high-stakes decisions in any field.

We also talked about the interview and interrogation techniques that actually work (hint: they involve rapport and, occasionally, French fries), and the moment his wife discovered details of an undercover operation. And he takes us inside his undercover operations—describing his strategies for successful missions.

“We told them: You may not, you must not—you have a duty not to obey an unlawful order.”

Pulitzer Prize–winning investigative reporter Bill Dedman calls Mark Fallon “the Serpico in the war on terror,” and high-ranking officials call him an American hero who’s made the world safer. Listen to the podcast—and you’ll understand why.
