Re: imagine if they had been....
Asian,
We probably would not have heard about the story unless maybe we lived in Asia and they reported it in the Asian press, never having been there I assume they have newspapers and the like.
I'm not sure why you'd expect to hear about incidents involving Americans and Asians in the European press?
Similarly, I had a friend who mentioned that during the reporting of the Costa Concordia incident that the numbers breakdown mentioned Spanish, British, Italians etc. the rest of them were apparently Asian.
I would expect the Asian press to break it down similarly, so there were Chinese, Korean, Indian etc., the rest were from somewhere else.
I think you may be a British with Asian origins or an Asian living in Britain who's a bit disgruntled about the lack of Asian reporting, don't take it so personally, it's just a different part of the world.
