My initial reaction is a longing for a judge to declare, "baliff, kick these two nuts in the butt".
As for protocol, Spain can kiss it. As for their airline, nobody needs it.
As for profiling, I'd love to see tons more of it, but to grill suspicious Arab men, not to spare royalty. Sparing people is not why I'd profile, catching people is.
Unlike the other royal families of the present and of history, the royal family of Spain have been paragons of virtue and would never stoop (ala Billy-Goat Clinton, et al) to snorting something up their noses.
