Public demonstrations seem largely pointless. I mean, when a dozen people gather in a circle somewhere in California to protest China's treatment of Tibet, which Tibetian monk is really going to benefit? When a thousand or so people gather outside a soundproof building to chant slogans in protest of the business practices of the people inside the building, what decisions are really affected? When a few hundred UAW workers gather outside the gates of a closed auto plant in Michigan to protest NAFTA, whose mind in Washington, D.C. gets changed?
