I'm glad the govt was able to use this stuff to find Atta. Too bad the info was not used, in time to stop 9-11.
But the point remains, this sword can easily be pointed inward at us, and not only at foreign enemies.
Potential misuse of data by the gov't can be dealt with via laws. I'm not so sure what laws cover private corporations and data, particularly if that data is processed, stored, etc. overseas at some off-shored facility. Remember, once data becomes a commodity it can be purchased by anyone off the street or around the world.
