To not be hassled at the airport? The last time I checked, airports aren't actually known as the places where people expect reasonable and fair treatment.

And having read an article about Eric Duncan in the German "Stern" about how his case had been mis-handled by the U.S. agencies, I cannot blame anyone trying to take it into his own hands, even if I can see why this could be even more irresponsible.
