This is truly a sort of bandwagon issue. People join it because it's the in thing at the moment, and not realising what they're criticising or supporting.
Many of the people who have been killed in the riots are from both Chinese and Tibetan ethnic backgrounds, and the riots in Tibet last month was done by ethnic Tibetans. When these rioters kill people, it does not do their cause justice.
China's move to restore order is something any other government would do in the face of rioting. American troops were sent into the Los Angeles riots in 1992, for instance.
People think that most of the deaths were due to the Chinese 'crackdown' as in restoring peace and detaining the rioters. But, since foreign media isn't allowed in to investigate this accusation leveled at China by the pro-Free Tibet movement outside China, it goes unsaid by foreign media. Most of the reporting has been anti-China in tone and content.
The Free Tibet movement aims to use disinformation based on China's past deeds as justification. As spectators in the events, and subject to the interpretations that the non-Chinese media has placed upon the situation, you can see that the deaths of innocent Tibetans and Chinese by the hands of ethnic Tibetans is manipulated into being a "Chinese crackdown" because China is a Communist country, and it controls Tibet.
In a large part, the problem lies with the veracity of the reporting, and the inaccessibility to the region. Once the Olympics are over, the same problems will be there. Mr. Gere will return to being a small voice in the background noise of everyday life again, and the world moves on to another thing to occupy it's attention, maybe another 9-11.
