nope!!! simple, there is no need for that!!! those culprits are being brought to the justice, slowly, as long as they are still in china!!! that would be more effective than 示威 on the streets of china.
outside of china, it was the time to show the unity of people of china to the assholes of your kind that tibet would be a a part of china, forever!!!
those protests show the wrath of the silent majority of oversea chinese: "you kind has gone too far and too nasty, it is the time to hear our voice".
