If you go to the USA from Europe (and presumably other countries) you have to fill out a form to get a tourist visa which you usually do on the plane.
One of the question is: “Are you a terrorist?”.
Now this question is so obviously dumb that I find it hard to believe that they are doing this in hope the terrorists are totally honest. So I wonder if there is some legal or other good reason why they ask that. I have various wags:
To cover the airline company. They can’t legally carry terrorists so they need to make it clear they were officially unaware of the evil intentions;
To supply an additional crime, namely perjury, to charge the terrorists with;
To give someone who is perhaps having second thoughts the final nudge to fess up.
None of these have me totally convinced, though, so I’m hoping someone knows the actual reason.
