Did you read my account of the experience my son, his friend, and the friend's elderly auntie and uncle had when they were going to Vietnam? I'm quite sure that it wouldn't have happened if they had been white. (Not the TSA people aren't ever asses toward white people; they are. But in the context of the situation, I'm pretty sure this had to do with their being Asian.) It made me really worried about what might happen when my son and his friend (both U.S. citizens) came back into the country, but that went smoothly.
