Yet another reason not to fly. Just watched a show where they talked about how your entire life could be mapped. Every keystroke, call, email and text could be recorded and your footsteps could be trace electronically to show exactly where you went and what you do. By analyzing samples in San Francisco they could determine what people were most likely to suffer from diabetes, heart disease, alcoholism, etc. This is of course contingent upon you giving permission for said tracking.
This morning saw an article on how the IRS is tracking social media like facebook, ebay auctions and betting houses to find tax cheats. Sort of like the data mining done by marketers to target spending habits, but with access to social security numbers, bank accounts and all personal data.
Wonders why people are so upset about spy drones.
