More information released by Edward Snowden and reported over the weekend by The New York Times shows that the NSA is tapping into "material from public, commercial and other sources, including bank codes, insurance information, Facebook profiles, passenger manifests, voter registration rolls and GPS location information, as well as property records and unspecified tax data." That information is added to our e-mails and phone call "metadata." From all these sources, the Times reports, is created a "portrait of an individual, one that is perhaps more complete and predictive of behavior than could be obtained by listening to phone conversations or reading e-mails, experts say."
