I think it's more people than people think... 10% of people living in america are not citizens. 90% of people are. If their definition of 'foreign' is 'non-citizen' and they only have to be 51% certain that someone is foreign, that is a 49% error rate, which means (at a maximum) 90% of the people they have in their databases and are tracking are american citizens. If they had to be 91% certain, that's a 9% error rate, and they would have a database that 52% are american citizens...
