So, when Coleman came to the microphone before the Brookings-blue logos of the stage, I was curious to see how her presentation of the social dynamics of Anonymous might be perceived. She described the group's birth on 4chan and the turn that some groups within the larger mass took to engage in activist politics in 2008, changes that came in the process of griefing the Church of Scientology in Project Chanology. Through that experience, various Anons developed the digital and physical moves that they'd later use on other organizations.

She covered several other notable Anonymous and AnonOps (separate group) exploits. What was fascinating about her talk was the way that it gave the impression that -- much as people would like to -- it is very difficult to separate out the different kinds of activities that define Anonymous' do-ocracy. Anonymous, a bit like Occupy Wall Street, is as much a platform for action as anything else, and individual efforts are largely separate from any other effort. This massive decentralization of power makes it difficult for Anonymous to stand for any one thing or even to ask that question of itself as an institution. It wouldn't make sense to say, "What are Anonymous' politics?" even if it seems clear that, in inchoate, intuitive form, there are some.

Coleman also highlighted the way Anons follow a strictly enforced "no fame" policy in which those members who seek celebrity are shunned. But inside the group, individuality is encouraged. The whole enterprise is "evasive, shifty, and nomadic," but not necessarily in a bad way.

That style is also a strategy. As Richard Forno, the graduate program director of University of Maryland, Baltimore County's cybersecurity program, explained, for those trying to defend their organizations an Anonymous attack, the very fact that no one controls the operation makes it difficult to strike back. Beyond any technical resilience the hackers build into an operation, the anonymity and decentralization create a social resilience. There's no one person to apprehend, no organization to strike, nothing to hit.

The last speaker was Paul Rosenzweig. Rosenzweig has a classic Washington resume: University of Chicago JD, lecturer at George Washington Law School, visiting fellow at the conservative Heritage Foundation, various posts at the Department of Homeland Security, and a bow tie.

I have to admit that he did not strike me as likely to understand or feel much sympathy for Anonymous. But Rosenszweig did a fantastic job of framing the group's activities for the policy crowd. "I offer the comments with a great degree of uncertainty and trepidation," he began, and then used the nominal title of the panel, "Hacktivism, Vigilantism and Collective Action in a Digital Age," as a way of illuminating different aspects of Anonymous and how policymakers might respond to it. Far from the befuddled establishment lawyer that I expected, Rosenszweig's sensitivity to the multivalence of Anonymous impressed me. We can only hope that other people whispering into lawmakers' ears are as intellectually curious as he is.
