> Most airports worldwide, including in the U.S., don’t scan passenger luggage for cash, a costly undertaking in equipment and personnel. I think this is false. Anytime I've flown with cash in my checked in luggage, it was always stolen and it was obvious someone went through my suitcase. Then I stopped doing that obviously. (happened in U.S. and Indonesia)
Airport security, the world over, is a magnet for criminals to self-organise, or be replaced by those who do.
