Anonymity, masks, and accountability

A man was convicted by his own heartbeat — and that's just the beginning of our digital dystopia.

About the Guest

Andrew Guthrie Ferguson is Professor of Law at George Washington University Law School and a national expert on surveillance technologies, policing, and criminal justice. He is an elected member of the American Law Institute and the author of the PROSE Award–winning The Rise of Big Data Policing. His new book, Your Data Will Be Used Against You: Policing in the Age of Self-Surveillance (NYU Press, March 2026), examines how smart devices and digital surveillance are transforming criminal prosecution — and what the law must do to catch up.

About This Episode

Following yesterday’s conversation with Christopher Mathias about doxxing and the ethics of unmasking, Andrew Keen turns to the legal side of the same question: what happens when the data we generate about ourselves becomes evidence? Andrew Guthrie Ferguson joins the show from Washington, D.C. to discuss his new book — a deeply researched investigation into how pacemakers, smartphones, smart cars, and doorbell cameras are being used to convict people in court, and why the law has almost nothing to say about it.

The conversation moves from a man convicted by his own heartbeat to AI-powered real-time crime centres, from Eric Schmidt’s infamous privacy defence to masked ICE agents in Minneapolis, and from Bentham’s panopticon to Ferguson’s proposed “tyrant test” — a framework for designing data protections by imagining the worst leader with access to your most intimate information.
