Michael Fay was an American who was sentenced to caning by the Singaporean court. The United States felt this practice archaic. One of Singapore's senior ministers responded: "If you like it this way, that is your problem. But, that is not the path we choose"
Most importantly, there were plenty of Americans, I'd bet a majority, that agreed with Singapore. Not necessarily that we want caning in the US, but more that this boy didn't deserve any special treatment just because he was American.
To me it felt like the media (and, in fairness, the boy's parents) were really trying to play this up because it had the elements of a good story.
Essentially US cultural standards mark certain behaviors as horrible in the same way Muslim countries think women wearing a bikini is a crime. Very hard to change the way we think and arguably maybe we shouldn't change the way we think.
