Gothmund, a lot of pictures are photoshopped. I need only point at Playboy.
But, as I already stated... Did this photoshop alter the message, or even the whole situation? Nope. It made the picture more dramatic, but it still captured the reality: "US soldier is being approached by Iraqi man with child".
I trust the media to be reasonable in their editing, precisely because there are other media outlets that have different points of view, and might expose deception. Think about it: suppose CNN showed doctored footage of Iraqi troops executing innocent civilians, to make the Iraqis look bad. The very next day, you'd see an exclusive on BBC World showing the real deal. CNN would lose all credibility, and would lose loads of money...
No news outlet is "fair, honest and unbiased", that's just a myth. Journalists have egos, commercial news has a bottom line, government news has a message to spread. I trust other media (with opposite views) to keep the balance. No media source can go too far, because losing your credibility kills you: it's all you have.
