Dear,
Go to CNN's website and see if you can find something to support your allegation. I certainly trust what you have said about what happened in Tibet.

What I don't understand is your allegation about CNN. You mean they never reported the violence caused by Tibetan people? That was not the case.
They did. If they did, would you change your points?

I think clear thinking and independent thinking are crucial in today's China.

Following the highly distorted "public opinion" is not wise.

Even if
CNN made a lot of mistakes on Tibetan issue, does it mean CNN making mistakes in all kinds of reports?

 Even if CNN makes mistakes in all its coverage, does it mean all American media should take the blame?

Even if all American media makes mistakes, does it mean all western media are anti-China?

I never know how Chinese people could go crazy to make this kind of quantum leap forward without any evidence.
I am glad that you know American media is probably the best or at leat the most important in this world.

Then I will ask you: what makes American media great? Did you ever think about this? They have much higher professional standard.

Under this kind of standard, it is much harder to them to make mistakes in a systemic way.

As a matter of fact, if CNN had made fundamental mistake, there would be a lot of blames within American media circle.

 Unfortunately, they did make such a mistake. All American media stands behind them. They support CNN.

Did you notice that CNN was invited by our government to cover the torch relay on Mt Everest? Few foreign media got the chance. 

Did you ever think about if CNN really infuriated Chinese government, would they still be invited?
Was our government crazy? No, it wasn't crazy.

 It was a way for our government to calm CNN down because of the unfair and distorted treatment on it. That's why CNN tried to stay quiet instead of making a lot of noises.

You have to go deeper to see the mechanism, dear.

On its website, CNN has used very fancy way to highlight the torch relay route. Very impressive. Even glorious.

Attach a friend's article about the CNN incident. See if you like it.
All governments want to control or influence media. US government is no exception. The truth is, in America, it is harder than other countries.

 Tell me about the whole thing you have seen on the CIA propaganda documentary.
The cause? The procedure? The consequence? Who told you the story? It is American media. Can you see the self-correcting way of American media?

Can you draw the conclusion that American media is also propaganda through one single isolated case?

If you have the time to go deeper, you will see the mechanism through which how American media fend off the interferrence from government. This kind of thing still happens.

 A couple of weeks ago, a bunch of military analysts on TV networks have been all fired because NY Times disclosed that they accepted instructions from the Pentagon.
For obvious reasons, the Pentagon and CIA have the strongest interests in influencing media.

You know the Pentagon Paper case in Vietnam War era? Find some materials about it and see why American media is great. In that case,
it was the NY Times and the Washington Post who fought the US government in a courageous way. It is one of the landmarks of American media.

I probably know much more about why American media is far from perfect. I like it not because I think it is perfect but because it is the best and
because it has the highest professional standard.
It will be more interesting if we can discuss specific reports. If it is hard for TV, you can try to follow the newspapers or magazines.
