"It is not just a concept that indulges protesters, it is a device that stabilizes government, promotes order rather than chaos, and productively ameliorates the tensions of pluralism. Most directly, civil disobedience constitutes a stabilizing or corrective device, allowing a democratic system to rectify its mistakes. By standing on the border between legal protest and rebellion, civil disobedience serves as a firebreak preventing the disaffected from inching toward rebellion. To illuminate this same concept, envision civil disobedience as a safety valve, drawing off dissent before that unrest boils over into more severe law breaking."
