I think questions at a border don't really fall under the fifth, as you're submitting to them voluntarily because you want to get in the country. You can refuse to answer any question, of course, but then the border agents can refuse to let you into the country.

I'm not sure if the goal is solely to stop "truly bad guys" who want to bring down a plane from getting on it, but rather make a note of anyone who might be traveling under false pretenses for any number of reasons.

This is what I'm afraid of. Is travel on a plane now squarely reserved for the honest or those with nothing to hide? There are plenty of very legitimate reasons to travel under false pretenses, including it would seem, hiding from one's own government because of some irrational administrator who decides to use air travel restrictions to carry out a grudge. The restriction on travel, especially within the US as applied to US citizens is very disturbing as it represents a fundamental erosion of our freedoms. Take a look at this case as just one example:

Not at all. They'll still let you on the plane after grilling you. They just want to know that you're hiding something. For future reference.

It's hard to tell sarcasm over this medium, but are you suggesting that being asking someone questions about their travel plans and retaining notes derived from to the answers is not an appropriate power to give the TSA? Is there any country in the world where airport security doesn't have this power, and is it practically feasible?
