New submitter FarnsworthG writes A news story about the capture of a kidnapper mentioned that he was caught because a car dealer had secretly installed a GPS device on his car. Apparently this is becoming common for "buy-here-pay-here" dealers. The devices are sold by Spireon, among many others. Raises interesting privacy questions. FarnsworthG also points to this Jalopnik article condemning the practice, when it's done without disclosure. The kidnapping itself, of Philadelphia nursing assistant Carlesha Freeland-Gaither, was captured by a surveillance camera.
