The idea of free press is not to get a completely accurate and unbiased press, the idea is to get biased press from all sides, so the lies and bias kinda cancel eachother out. it's not a perfect system, but it's the best we've got (actually the internet blogging 'culture' is a new form of 'press' it would seem).

What's dangerous is one organization, or one person controlling all the media, then you have something to worry about.
