The Supreme Court seems a bit nervous about letting the police track you with your phone

Key Points:

• The Supreme Court is hearing Chatrie v. United States, a case addressing when police can use cellphone location data to identify individuals near a crime scene, with initial arguments suggesting skepticism toward strict privacy limits on government tracking.
• Concerns arose among justices about the potential for government overreach, such as tracking attendees of religious or political gatherings and accessing private emails or photos without warrants, indicating the Court may uphold Carpenter v. United States (2018) protections requiring warrants for cellphone tracking.
• The case involves "geofence" warrants, which allow police to obtain location data within a specified area and time frame; in Chatrie, police used such a warrant to identify suspects near a bank robbery, with Google providing anonymized data before revealing identities.
• Justices appear divided: some, like Thomas and Alito, favor easing warrant requirements for location data accessible via opt-in services, while others, including Roberts, Gorsuch, and Barrett, express privacy concerns about broad government access to sensitive data.
• The Court is expected to issue a nuanced ruling that maintains existing warrant requirements for cellphone tracking but may not impose significant new restrictions, leaving unresolved questions about the scope of privacy protections in future cases involving political or religious group tracking.
