Civil disobedience is an important form of democracy. Maybe in the future, when all of our calls, messages and identities are monitored in full by our benevolent overlords, we won't be able to practice it anymore. Right or wrong, faraway anti-Western countries have served as counterweights against the West for Snowden, Assange and Elbakyan.
Do you mean by suppressing the action before it occurs? I thought that one of the points of civil disobedience was to get caught, so as to increase visibility of the problem and become a catalyst for change.
