The NSA does not target Americans' location data by design, but the agency acquires a substantial amount of information on the whereabouts of domestic cellphones "incidentally," a legal term that connotes a foreseeable but not deliberate result.
One senior collection manager, speaking on the condition of anonymity but with permission from the NSA, said "we are getting vast volumes" of location data from around the world by tapping into the cables that connect mobile networks globally and that serve U.S. cellphones as well as foreign ones. Additionally, data are often collected from the tens of millions of Americans who travel abroad with their cellphones every year.
In scale, scope and potential impact on privacy, the efforts to collect and analyze location data may be unsurpassed among the NSA surveillance programs that have been disclosed since June. Analysts can find cellphones anywhere in the world, retrace their movements and expose hidden relationships among the people using them.
See? The Phantom is never wrong. They really do track cell phone location, and have been doing so for some years now.
