The Supreme Court is set to make a decision on the legality of ‘geofence warrants’ soon. The case, Chatrie v. United States, stems from a 2019 bank robbery using such a warrant to identify and arrest Okello Chatrie. Geofence warrants, used by police, involve collecting data from large tech companies like Google to identify any individual within a certain location during a crime to find suspects. The case raises privacy concerns for cellphone users regarding the extent to which location data is protected.
In Chatrie’s case, police used Google Maps’ Location History to pinpoint Chatrie’s whereabouts to within three meters, requesting data on persons near the robbery scene. Once identified as a key suspect, Chatrie contested that this amounted to unreasonable search and seizure, claiming a Fourth Amendment violation. A District Court initially agreed but later sided with the government under a “good faith exception,” and a federal appeals court found no constitutional violation as Chatrie had shared his location with Google voluntarily.
The Supreme Court will rule soon on the matter. Although Google’s 2024 decision to stop storing location history in the cloud questioned the necessity of the case, the implications remain significant, touching on similar practices by companies like Uber and Lyft. The case will affect how police conduct digital searches, particularly in situations without a known suspect or device.
As police initially received anonymized data from 19 users and narrowed down to Chatrie via additional requests, the process itself raised concerns about the randomness and potential intrusiveness of such warrants. Despite some judicial skepticism, some Justices, like Brett Kavanaugh, viewed it as diligent police work.
The case delves into whether accessing geofence data without a warrant constitutes a search and probes the line between property interests and privacy expectations. While some justices opposed the property argument that individuals “manage” their data, the Katz test brings into question if such practices breach a privacy expectation.
The Supreme Court’s decision could draw from past rulings like Carpenter v. United States, which required warrants for cellphone tower location records. Despite changes in the Court’s composition since 2018, the decision will clarify the scope of digital privacy and government reach. It questions the extent to which personal digital data, when stored by companies, remains protected from warrantless searches, thus influencing future privacy rights interpretations.
