Well, to be perfectly honest, I have no way of telling how biased the stories on the news are, unless I actually go to Iraq and do some investigation of my own.
I beleive (again, I don't know for sure) that both FoxNews and NPR report accurate facts when it comes to their stories. I think the liberal bias in NPR is exaggerated, and the conservative bias in FoxNews is greatly exaggerated.
The bias that does exist primarily manifests itself in which stories the media chooses to cover. A lot of news happens every day, but who decides what should be reported on, and what shouldn't? The media, of course...this is how they function as 'gatekeeper'--they have influence over which issues get public attention, and how much. For example, as I said in another thread, during the war NPR may choose to take a lot of time covering the looting of museums in Baghdad. Meanwhile, FoxNews might spend more time covering a unit of American troops and their progress in the invasion. Both stories are accurate, but the people in the media have to decide which one to focus on, and to do that they have to rely on their own opinions/biases.
