Well, you DID google "Haditha massacre." Hence, it's only natural that the sources you'd get are all those which are so inflammatory that they would call it a "massacre." Even if accurate, "massacre" just has an explosive tone. What does this mean then? That AP, UPI, Reuters, and the major newspapers aren't calling it a massacre, or aren't presuming that their audience knowns what Haditha is so as to place the words closest to each other.... or they've moved on.
Googling just "Haditha" got me Reuters, Bloomberg, Daily Telegraph, Chicago Tribune, Fox News, CBC, ABC, CBS-5, NPR, Washington Post, Washington Times, and NY Times. I would also not be surprised if there were some less hystrionic news sources which simply moved on already.
Of course, that still doesn't mean Google isn't Satanicly evil.
I know it's a chore to actually read the thread, but all of your (obvious and errant) points have been previously addressed.
Don't go getting all logical.
