No. Violence is too emotional and it only causes others to respond by violence. Proper communication is the key.

Not ever!! The violence becomes the focus, rather than the message. It is a self-defeating method of protest.

I am of two minds on this. On the one hand my philosophy in life is that violence begets violence and that one should abstain from being a source of violence, the other hand demonstrates that there is a point where violence is the only way to communicate that will be heard. Unfortunately governments are mostly deaf, and some times it requires a big stick to get their attention before they will listen. In the case of China - the people revolt against their government because they dislike its policies. This is a step in the direction of a form of democracy. Democracy should never, ever be handed to any people without their desire for that. Instead a true democracy is best won through the blood and martyrs who sacrificed their lives to bring about a revolution. Countries that won their own democracies in their own blood tend to keep those democracies longer than those who have some other nation come in and kick but and hand it to them. A people who are free should be more than willing to take up arms and oppose those who dare to take their freedom from them. Thus if the US government should make the mistake to take away the constitution and our freedom, then we are, but the nature of the dire threat, called to duty to rise up and by opposing - violently - the threat, end it and restore that constitution and the freedoms that we all enjoy. I would rather that all people wake up one day and find themselves free, and find that all would be tyrants have died in their sleep. Thus peace could be maintained and no man would need to rise to violence to win his rights. But I am a realist, I understand the reasons behind violent protests.
