You say that, but I've seen my fair share of news articles about chalky Brits being sent back home; usually for stuff like offensive content found on their phones (the one that comes to mind, was someone being rejected entry because he had the fat Vance meme saved in his images automatically by a WhatsApp chat).

I suppose Americans wouldn't even be aware that foreigners are liable to these checks prior to entry, or that governments like Germany and the UK have put up travel advisories warning against visiting. Crazy to think about given it's such common knowledge the world over... Some NK level of public deception.
