Here's Shen Tong, one of the organizers of the Tiananmen Square protests in 1989, from his book "Almost a Revolution." This is just after one of the first student marches...
"We have completely achieved our goal today... Being here is a victory in itself. We walked past five universities over a long distance and reached Tiananmen Square. What we wanted to do was to use nonviolent means to protest the beating of patriotic students in front of Xinhuamen this morning, and to ask the government to reevaluate Hu Yaobong's ouster from the Party. We have not disrupted society, we have not halted traffic. We have done this in a very orderly way." (p. 182)
Here's Wael Ghonim, one of the facebook organizers for the Egyptian revolution, in his book "Revolution 2.0:"
This is rule Guideline #1 of 8 protesting guidelines:
"The protests are peaceful. We are peace advocates and not advocates of violence. We are demanding our rights and must uphold the rights of others. We will not respond to any provocation from security forces and lose control. This is what they want us to do. One of the security forces' main goals is to portray the protesters as thugs who want to destroy the country. We must discipline ourselves and refrain from foolishness or any violations of the law, and we must not endanger any person's life or cause harm to any public or private property. If you see someone behaving violently, please circle around this person and take him out of the protests." (p. 157-8)
