dunno how that works in the US, but i think in most of Europe, at airports, if customs spot fake gear on you(watches , designer clothes,fake perfum), or in your luggage, they will confiscate it...
they are especially watchfull for folks coming back from say China... it's actually an offence of some sort to buy counterfit goods...

don't ask me how they enforce it , and how far they will take it, but i know for fact that in Schiphol they go after these sort of things...
