Yon's story doesn't get attention because it is humiliating.
It is humiliating because it is obvious that we media – and our allies in the state department, the legal trade, the NGOs, the Democratic Party, the UN, etc., - can’t do squat about such determined use of force.
Our words, images, arguments and skills can’t stop the killing. Only the rough soldiers and their guns can solve the problem, and we won’t admit that fact because the admission would weaken our influence and our claim to social status.
So we pretend Yon’s massacre – and the North Korean killing fields, the Arab treatment of women, the Arab hatred of Israel, etc. - doesn’t exist, and instead focus our emotions and attention on the somewhat-bad domestic things that we can ‘fix’ with our DC-based allies. Things such as Abu Ghraib, wiretapping, etc. When we ‘fix’ them, then we get status, applause, power, new jobs, ego, etc.
Please don’t be surprised. We media are an interest group not much different from the automakers, the unions, and the farmers.
The good news is that there is someone willing to admit it. The bad news is that it had to be admitted, and there's still not enough people willing to admit it.
