There are approximately 500 million airline passengers annually (see http://www.faa.gov/apa/speeches/031298spjg.htm, in which Jane F. Garvey, FAA Administrator says "The number of passengers carried on commercial aircraft will nearly double over the next 15 years, reaching one billion by 2015.") If a dozen of these passengers try to hijack or blow up planes annually, this system will identify 50,000,000 people (or about 100 per minute or 1 out of every 10 passengers on each flight) as potential criminals. Of these, 9 (75% of the actual 'criminals') will be actually intending to commit criminal acts. Then what? How do you separate the wheat from the chaff? And don't forget that this system missed 3 passengers who presumably went on to commit the criminal acts they intended.
