Chatrie v. United States: A privacy victory before the Supreme Court
The Supreme Court ruled in Chatrie v. United States on the constitutionality of geofence warrants, which compel tech companies to hand over location data for all devices near a specific place and time. The decision represents a significant moment for digital privacy rights and Fourth Amendment protections in the context of modern law enforcement tools.
Why this matters: Geofence warrants are a dragnet. Police define a location, a time window, and then demand data on everyone whose phone was there. You do not need to be a suspect to get swept in. This ruling sets a limit on that. It matters because the tool has been used in hundreds of thousands of cases, often against people who had nothing to do with anything. A court finally drawing a line here means location data is not a free pass for law enforcement just because a tech company already has it.
