I completely sympathize with where you're coming from, Curr. I used to think more of your way. But you're also acting a bit naive about what defines "news".
Body counts aren't the only way to measure a tragedy (I give enough crap to people who use body counts as a dick-measuring stick to "brag" about whether their genocide was worse). And body counts are not entirely a way to measure news either.
"News" is just that -- the "new" part. Unfortunately we don't hear about 15 people getting blown up in Iraq because it's such a routine occurrence that it technically does not fall high on the "news" category. People getting blown up at an internationally-renowned sporting event is.
To put this another way, if Saddam Hussein executed 15 of his citizens, that would not be news. But if George W Bush executed just one U.S. citizen, hell yeah that would be a much bigger news story. It's not a judgement of whether those 15 were "worth less" than the one American.
