They can't NOT get the truth, they're living it.
As for media coverage, if think that over in Iraq, they get even more pro-US bias due to the fact that the US monitors all media channels and censors the ones who are too explicitly anti-American.
However, while we rely only on media (well, most people for the most part), they have the advantage of being there. They talk to people on the streets, their friends and family and they gather and discuss and generally they can get first or second hand information much better (obviously) than we can. This is more valuable than any media source, since you can't spin reality.
