Nothing to worry about if you're innocent.

What next, mandatory DNA database submission?

K and R

Why-why back (60's or so) , if you filled out a card at your local B&R's ice cream store with you child's birthday on it, the kiddies got a free ice-cream cone on that special day. Family fun - right? You and the kids eating your cones in the glow of something special. Well, not so special. The U.S. government got ahold of these cards, formed a database and made sure when the kid became draft eligible , they were called up.
Program stopped when the shit hit the fan. They still have the birthday cards, but cut their strings to the Selective Service. Yes, I know there are probably a dozen or maybe a hundred ways to make sure Johnny got his gun and got called up to serve as cannon fodder, but B&R's didn't need to help.

It was only a matter of time.

The goal of wholesale surveillance, as Arendt wrote in “The Origins of Totalitarianism,” is not, in the end, to discover crimes, “but to be on hand when the government decides to arrest a certain category of the population.” And because Americans’ emails, phone conversations, Web searches and geographical movements are recorded and stored in perpetuity in government databases, there will be more than enough “evidence” to seize us should the state deem it necessary. This information waits like a deadly virus inside government vaults to be turned against us. It does not matter how trivial or innocent that information is. In totalitarian states, justice, like truth, is irrelevant.
