I didn't say it was media's fault alone, but their share of responsibility is a large one. How else would the Bush administration have gained the support of the public? By transmitting their falsehoods through popular private media corporations such as CNN. And the media were all too happy to lap up the narrative fed by the administration without bothering to investigate deeper.

Not investigating deeper is different than outright lying for propaganda. "The President Said X" is newsworthy though maybe lazy reporting. If X is a lie it's on the president.
