For better or worse, the notion of censoring or controlling the media has fallen by the wayside in the modern world. First - a government is only capable of applying its laws to the media that resides with in its own borders. Second - today the average interested citizen obtains a mere fraction of their information from the traditional media, be that newspapers, periodicals, the radio or national network television. In the last 5 years The Druge Report, Aljazeera and the blogg community have blown the lid off the major media oligopoly. Today the corporately controlled media sector is just passing on what has already made it out into the public domain via other channels. I disagree that the media was controlled by the government for the first year or so of the Iraq war. I really don't think the U.S. government is that sophisticated. I think what was seen in the media was a combination of two things; the bias of the media outlets, some were more pro-war than others, and a race to grab ratings by giving the public what they wanted to see, and in the early stages with a generally pro-war public, that was good news stories about how well the war was going.
And one final point, if military secrets are so poorly guarded that the media can get to them, do you not think the enemy could get the same information? Are the media not performing a due dillegence role for the military by letting them know that they have a leak somewhere?
