Supreme Court says police need warrants for 'geofence' searches to track cellphones near crimes

The Supreme Court's decision mandates that police must secure warrants for geofence searches, where they track cellphones near crime scenes by requesting telecom companies' location data. This ruling underscores the need for judicial oversight in modern surveillance methods, balancing law enforcement's investigative needs with individual privacy rights. The ruling sets a significant precedent, clarifying the legal landscape for digital tracking technologies and reinforcing the Fourth Amendment protections against unreasonable searches.
