Do You Know How Your Phone Works?
Summary
Hosts Roman Mars and Elizabeth Joe analyze *Chatri v. United States*, a Supreme Court case ruling that geofence warrants constitute a Fourth Amendment search. They explain how the decision protects users’ location history, even when voluntarily shared with Google, by rejecting the "third-party doctrine" for digital data. The episode connects this privacy precedent to broader surveillance issues, including license plate readers and lobster boat tracking, illustrating how constitutional law adapts to modern technology.
