LA Cops Fight Car Chases With GPS Devices
The Los Angeles Police Department (LAPD) will become the first law enforcement agency to outfit cars with a device that propels and sticks a Global Positioning System (GPS) onto a fleeing car.
The department will mount the StarChase LLC device in the grill of some squad cars in the fall. “Officers in the car would control a green lazar light, similar to an aiming device that fixes on your target,” said LAPD Lieutenant Paul Vernon on Friday. “A small dart-like device is propelled from the officer’s car.”
