Police in Dallas, TX are kicking themselves in the ass after the GPS functionality of a "bait car" has failed and their baited criminal has gotten away, scott-free, with a new car. Bait cars are cars prepped for the purpose of being stolen. They have GPS tracking, cameras and other remote sensors. Once a thief takes the car, the police just use the GPS to track down the criminal and make an arrest.
In this case it is a bit of a problem, because the GPS functionality on the bait car failed entirely. So the Dallas PD basically gave a car away to a criminal. Sure, the thief could have disabled the GPS somehow, but I think I'll call it a user-error.
