Last summer here in Nashville, there were 8 neo-Nazi marches. What is social media’s role in fueling — or even enabling — political violence? How do algorithmic echo chambers, disinformation loops, encrypted organizing platforms, and the erosion of trust in institutions converge to create real-world harm? And what can be done to hold systems and actors accountable before the spiral becomes irreversible? To guide that conversation, we’re honored to have Timothy J. Heaphy with us. His vantage is rare: He’s been on the front lines of investigating two of the most consequential episodes of recent American unrest — Charlottesville in 2017 and the January 6, 2021 Capitol siege — and in his new book Harbingers: What January 6 and Charlottesville Reveal About Rising Threats to American Democracy, he tells both the story of how these events unfolded and the deeper dynamics behind them. Timothy Heaphy’s career spans decades of legal, prosecutorial, and public service work, giving him deep institutional insight and investigative experience. A graduate of the University of Virginia (B.A. and J.D., 1991), he spent over a decade as an Assistant U.S. Attorney in Washington, D.C., and later in the Western District of Virginia, handling a range of federal prosecutions. After moving into private practice, he was nominated by President Barack Obama in 2009 to serve as U.S. Attorney for the Western District of Virginia, where he oversaw major investigations into corruption, fraud, civil rights, and national security. Following his tenure, Heaphy returned to private practice and later became University Counsel at UVA. In 2017, he authored Charlottesville’s independent report on the “Unite the Right” rally, and in 2021, he was appointed chief investigative counsel for the House Select Committee investigating the January 6 attack on the U.S. Capitol, directing its investigative and legal teams. He also founded The Fountain Fund, a nonprofit supporting reentry for formerly incarcerated individuals. Throughout his career, Heaphy has combined legal expertise, public service, and investigative leadership in some of the most consequential inquiries of recent years. In his book, Harbingers, Heaphy brings that rich background to bear on two momentous acts of political violence: the 2017 Charlottesville rally and the January 6 Capitol attack. He doesn’t just rehash the facts — he shows how he built investigative teams, how he sifted through communications, how he probed decision-making failures in law enforcement and government, and how social media and digital networks played roles in planning, mobilization, and escalation. In today’s episode, we’ll use Harbingers not just as narrative backbone, but as a portal into deeper inquiry: How did social media architectures and incentives — content moderation policies, recommendation systems, coordinated groups — intersect with extremist organization and violence? Where did institutions (local government, law enforcement, federal agencies) fail to anticipate or respond — and why? What are the paths forward for accountability, reform, civic resilience, and prevention? So let’s dive in, first by asking: when does online grievance cross the line toward violence — and what makes that line blur in 21st-century politics?
