How the NSA Is Using Cell Phone Data to Drone Civilians (In Pakistan) - Atlantic Wire
By September 2004, a new NSA technique enabled the agency to find cellphones even when they were turned off. JSOC troops called this “The Find,” and it gave them thousands of new targets, including members of a burgeoning al-Qaeda-sponsored insurgency in Iraq, according to members of the unit.
At the same time, the NSA developed a new computer linkup called the Real Time Regional Gateway into which the military and intelligence officers could feed every bit of data or seized documents and get back a phone number or list of potential targets. It also allowed commanders to see, on a screen, every type of surveillance available in a given territory.
