His real crime is probably that he didn't fly first class.
Certainly the cause for the arrest - too much money for a worker.
4700 is a lot of money - more than I've ever had in my hand at one time (though it's been four digits before, easily) - I can *see* why someone would ask (if they happened to know. I've certainly never yet been asked to open my wallet at an airport.
) I can then *see* why he might be arrested if he behaved the way cops - and especially US cops by the way they're portrayed in books and films - don't like to be behaved to. Such as telling them they have no legal right to know or something. Which doesn't make it *the right thing to do*.
So yah, in between the Blue&Yellow Avatars on the one side, and Verily on the other.
