The point is you want journalists working in an environment where it is expected people stay neutral. Whilst one person will have a bias, you always have other people who read the piece and edit it to keep that in check. That sort of person, even if they are just as biased as independent reporter X, will produce much more balanced work. It's all well and good to say "Oh everybody has a bias" but everybody's bias is not as large as anothers, and doesn't affect their writing in the same way. I would much rather read pieces by a reporter like Greenwald that makes it clear where he stands, than a journalist that pretends - maybe even to himself/herself - that there is an objective truth they can report. That's fine- as I said, you can read what you want. I'm just explaining why a lot of people see it differently.
