So many good posts on this topic. Those of you who have basically said, "no big deal, that information is already out there" should consider this: yes, the info is already out there. But for now, at least for the most part, it is not consolidated. Those of you old enough to remember, think of doing research papers before the internet. You had to go to one library, find the reference book, copy the stuff by hand (they didn't let you check out the reference volumes), then go to another library to see if they had another reference you couldn't find at the first library. Then you had to go through, assemble the information, footnote the credits, etc. etc. etc. Then you typed it out on your newfangled IBM Selectric. Now, with the internet, you do a google search, select 10 or 20 of the tens of thousands of hits, save the pages, cut & paste into Word, index a few keywords, and click "print."
As for the reference to the blue-eyed, blonde-haired lady who ended up on the "watchlist," funny thing that... those watchlists are created by an archaic technology called "soundex." Do a google search on that one sometime. The technology by itself is not that frightening, but the way that the results generated by Soundex are put to use is just mind-boggling.
As I have pointed out elsewhere, the drivers license with smartcard technology linked to national ID databases should terrify every red-blooded patriotic American. Any one situation where your ID is currently requested would be linked to every other situation. I certainly do not want my library reading choices or my Wal-Mart purchases to affect my auto insurance or my ability to board an airplane. Oh, and your voting record would probably also be tied in there. Careful, you could become an "enemy combatant" without realizing it. Then they can lock you away indefinitely, without any charges, without counsel, and without notifying anyone. With the Patriot Act in place, Amendments IV, V, and VI are about as useful as the little curlicues & serifs adorning the letters of the original Constitution - they look good, but do absolutely nothing.
