Your Location Data Gets a Shield, but the Backdoor Stays Wide Open

The Brief

The Fourth Amendment Reclaims Your Location Data

In Chatrie v. United States, the Supreme Court ruled that citizens hold a reasonable expectation of privacy in their physical location history.

Justice Elena Kagan, writing for the majority, compared this digital trail to private papers and photographs, effectively ending the era of warrantless virtual sweeps. The case began when Virginia police swept up Okello Chatrie's location data during a 2019 robbery investigation, a technique that quickly ballooned to represent 25% of all warrants submitted to Google by 2021.

While civil liberties groups celebrated the decision, federal agencies are already finding ways around the courtroom. For instance, the Bureau of Alcohol, Tobacco, Firearms and Explosives recently admitted to conducting over 300 warrantless searches using Webloc, a commercial tool that harvests location data from everyday consumer apps.

Although the ATF canceled its Webloc contract under congressional pressure, the FBI and DHS continue to purchase commercial geolocation data from private brokers. This commercial data laundering allows the state to buy its way around the Bill of Rights, rendering the Supreme Court's latest shield only as strong as the next loophole.

By the numbers

• The Supreme Court ruled 6-3 in Chatrie v. United States on June 29, 2026.
• Geofence warrants grew to represent 25% of all warrants submitted to Google by 2021.
• The ATF admitted to conducting over 300 warrantless searches using the commercial tool Webloc.
• The original 2019 Richmond warrant covered a 150-meter radius, sweeping up data from hundreds of millions of Google users.
• The FBI and DHS continue to purchase commercial geolocation data from private brokers to bypass warrant requirements.

"Users have a 'reasonable expectation of privacy' in location history." — Justice Elena Kagan, writing for the majority in Chatrie v. United States

This ruling chips away at the outdated "third-party doctrine," which historically stripped your constitutional protections the moment you shared data with a private company. If the government can simply buy your entire movement history from a private broker, the Fourth Amendment becomes a paper tiger.

True digital liberty requires closing the commercial loophole so federal agencies cannot purchase the very information they are barred from seizing.

The government cannot legally track your phone without a warrant, but it can still buy your entire movement history from a private data broker.

What happens next: The battleground shifts to Congress, where the bipartisan Government Surveillance Reform Act seeks to permanently block federal agencies from purchasing commercial location data without a warrant.
