Police Chief William J. Bratton unveiled a strange new weapon in the police department's strategy to halt high-speed pursuits -- adhesive darts with a global positioning system that are fired at fleeing cars by police.
I think this is really cool, though I find it funny that the police will be using the equivalent of high-powered paintball guns ("A small number of patrol cars will be equipped with the compressed air launchers, which fire the miniature GPS receivers in a sticky compound resembling a golf ball.") to catch hi-speed drivers.
What happens if they miss and hit a different car?
