In terrorism fight, government finds a surprising ally: FedEx

FedEx has opened the international portion of its databases, including credit-card details, to government officials. It has created a police force recognized by the state of Tennessee that works alongside the Federal Bureau of Investigation. The company has rolled out radiation detectors at overseas facilities to detect dirty bombs and donated an airplane to federal researchers looking for a defense against shoulder-fired missiles.
Moreover, the company is encouraging its 250,000 employees to be spotters of would-be terrorists. It is setting up a system designed to send reports of suspicious activities directly to the Department of Homeland Security via a special computer link.
