Here are in a few points the situations in China and in Tibet on the eve of 2008 Beijing Olympics, if they take place. To end with the phrase: “we didn’t know”, to better understand the Tibetans’ revolt and that of Human rights’ defenders in China and all around the world, don’t forget these few elements:

Beyond more than a million dead after the Chinese invasion during the XXth century,

In these times of protest upon the 2008 Beijing OG, Human Rights’ defenders are regularly attacked. They are reproached a partial and anti-Chinese attitude. We can read and hear, for instance: and what about the invasion of Iraq?
You have to know that the invasion of Iraq is far from winning unanimity in the US; that the American book-shops are full of extremely virulent books against G.W.Bush and his politics; that since the beginning of the invasion, not one week elapses in the United States without anti-Bush demonstrations and that France was opposed to the invasion from the start (even if it was because they had huge investments in process there).
Don’t be doubtful about the fact that European and American streets would have been overcrowded with demonstrators in case the US would have been appointed to organise the 2008 Olympic Games, particularly in France, an a priori anti-Bush country.
Concerning Robert Ménart, his association is called “reporters sans Frontières” and is devoted to the denunciations of the exactions committed against journalists.
Some people expose Mr Ménart as being an anticommunist (China is a communist country?? Oh, well!! And the Olympic Games, a commercial operation led by sponsors like Coca cola, Mac Donald’s, EDF, Française des jeux, Adidas etc…, are the expression of the Socialist International?!); journalists are muzzled in China and banned from circulating freely in Tibet; that’s all.
Given the repressive politics of the CCP in Tibet, even if journalists had the right to circulate, any Tibetan who would talk to a journalist, or simply with a tourist, would be for it!
