The investigation centered around our discovery that at least seven California law enforcement agencies were using controversial high-tech cell phone tracking technology without the public's knowledge and no judicial oversight. They uncovered police from San Diego to Sacramento have been using fake cell towers, known as "Stingrays", for years and in complete secret. In fact, Sacramento judges and prosecutors had no idea the technology was being used until we approached them about the story. Grant applications obtained during our investigation showed law enforcement agencies used terrorism as the justification for purchasing Stingray technology, when in reality they were using the device for people suspected of far more routine crimes, including drugs and robberies.
