US terrorist watchlist "galloping toward the million mark"

The USA Today reports that the US anti-terror watchlist has grown to more than 755,000 people, growing at a rate of more than 200,000 people per year. As Slashdot notes, "Adding about 548 people daily every day of the year does not seem to lend itself to a manual process with careful deliberation given or double checking being done for each person added."
"They are quickly galloping towards the million mark – a mark of real distinction because the list is already cumbersome and is approaching absolutely useless," said Tim Sparapani of the American Civil Liberties Union.
