Photo- journalism

This isn't really related to what we've been speaking about in class recently, but I think it does relate to some major concepts we've discussed.....
Last weekend I was watching a documentary on the role that photo-journalism plays on society- and I was kind of shocked. Although these are photo=journalist, who are in the midst of the event, and capturing the moment through their media, so much of their work was not being shown to the public. They interviewed so many who had the same story: "they could not get their work published." It's like our government is trying to blind us of the harsh realities in all that are happening in other countries. If we can't get accurate information from photo-jounralist then who are we going to get it from ? How censored are we? They all said they went into this dangerous profession because this was the only way to alert people of what was really happening, and yet the majority of their work is still not being published. How can we accurately judge a situation (such as Iraq) if we are only looking through the censored version our government wants us to see?
