There's millions of people in the country, and quite a few in the city where they filmed. Interview all day and get a few hundred, and then show the dozen or so that didn't know anything. Instant cross-reference of America.
it is sad hope they expose americans like that. and true they could have got like 100 or more and show only the stupid answers, i think they should say . we interviewd 100 persons of that 60% knew 30% were wrong and 10% didn't know what we were talking about. some thing like that.
