Digital Privacy and the Future of the Fourth Amendment with Anne Voigts of Pillsbury
In this episode of The Business of Information, Chris Mohr sits down with returning guest Anne Voigts, Partner at Pillsbury, to unpack one of the most complex and consequential legal questions in the digital age: how the Fourth Amendment applies when law enforcement uses massive datasets to identify suspects after the fact. At the center of the conversation is United States v. Chatrie, a case involving geofence warrants that sweep in location data from potentially hundreds of millions of devices before narrowing to a suspect—raising urgent questions about privacy, surveillance, and constitutional limits in a world of pervasive data collection.
Chris and Anne break down how these warrants work, why courts are deeply divided on whether they even constitute a “search,” and how doctrines like the third-party rule are being stretched to their limits. They explore the tension between privacy and property-based interpretations of the Fourth Amendment, the risks of dragnet-style data collection, and the real-world implications for both individuals and tech companies. The conversation also examines how AI, data abundance, and evolving legal frameworks are reshaping expectations of privacy—and why this case could redefine the balance of power between government, platforms, and citizens.
In this conversation, you’ll hear:
* How geofence warrants work—and why they flip traditional search logic on its head
* Why the third-party doctrine is increasingly at odds with modern digital life
* The legal fragmentation across courts—and what it signals about future rulings
* The risks of large-scale data sweeps, including false arrests and privacy exposure
* How tech companies may respond if the government’s position prevails
* What this case reveals about the future of AI, data ownership, and constitutional protections
