"Among the various classes of protests—pro-life, anti-war, environmental, and now tea parties—the most destructive are the anti-globalization marches. So when cops clashed with anti-globalization demonstrators at the Pittsburgh G-20 summit in September, it was easy to assume that most of the altercations represented justified police responses to overzealous protesters. But a number of disturbing photographs, videos, and witness accounts told a different story. Along with similar evidence from other recent high-stakes political events, they reveal an increasing, disquieting willingness to smother even peaceful dissent." - Alex Scrivener
