False Positives Galore

Yesterday NPR's Morning Edition reported that the U.S. had 300,000 people on its "watch list," probably most of these gathered from tourists visiting the U.S. The focus was the legality of the uses to which this data has been put. But consider the effort required to correct a credit report in the U.S. Can you imagine the effort that would be required to remove misinformation that had been collected and put to untold uses? This calls into suspicion the underlying strategy, or rather the lack of same.
