"Chief William J. Bratton unveiled y a new and decidedly strange weapon in the LAPD's effort to halt high-speed pursuits. It is an air-propelled miniature dart equipped with a global positioning device. Once fired from a patrol car, it sticks to a fleeing motorist's vehicle and emits a radio signal to police. "Instead of us pushing them doing 70 or 80 miles an hour … this device allows us not to have to pursue after the car," Bratton said. "It allows us to start vectoring where the car is. Even if they bail out of the car, we'll have pretty much instantaneously information where they are."
