If we trust journalists to do it then we're trusting in something that never was. Journalism's always been about profit, not truth, to think it was ever otherwise is charming, idealistic, and completely contrary to objective reality. To trust in journalists really *is* an instance of trusting people who often have no idea what they refer to and are writing this to keep their companies in the black. To expect a profit-driven industry to be truthful is also to misunderstand the nature of profit.

So in short if the idea is unbiased journalism, then you might as well give it up because it'll never exist and the idea of non-profit information gathering is one that requires several leaps of technology and a complete redefinition of morality on a societal scale.
