<http://villagevoice.com/issues/0230/baard.php>Buying Trouble In which the Village Voice discusses the use of commercial databases including supermarket discount cards in hunting terrorists. One useful piece of advice: Don't but pizza with a credit card: Oddly enough, "one of the factors was if you were a person who frequently ordered pizza and paid with a credit card," Ponemon says, describing the buying habits of a nation of college students. "Sometimes data leads to an empirical inference when you add it to other variables. Whether this one is relevant or completely spurious remains to be seen, but those kinds of weird things happen with data." Course all those terrorists buying their pizzas with cash get away clean.
