I've had my own run-ins with police who were just "trying to help foreigners" (AKA pointlessly wasting their time) when I was in Malaysia a couple of years back. I also had my parents nearly get barred from entry into the US because they had forgotten to take down my sister's address when coming to visit her (she was waiting in the arrivals lounge).
Still and all, last night when I was speaking to a friend of mine in the US whose Korean girlfriend recently flew in to visit him who had an experience which shocked even me. Here's what the immigration officials at LAX said to this nice young woman from a respectable, influential Korean family before allowing her into the country:
"Who's your pimp?"
My friend put in a complaint, but the complaint went nowhere, and he was told that he was "lucky they even let her in the country". Yes, he was lucky that they let his girlfriend, someone with no prior convictions and no prior engagement in illegal activity, a talented young lady who works as a designer, into the country because they suspected her of being a prostitute based seemingly only on her ethnicity.
Seriously, is this what America is about nowadays? Being pointlessly rude, insulting, sexist, racially stereotypical and demeaning to foreigners visiting the country?
