This talk will cover the state of vigilante action around the world; what they fight with, who their targets are, how they stay anonymous, and how they organize. Without condemning or condoning any single act, these radically unique responses to crime and corruption deserve our attention. How much power are they wielding? Is nonviolence winning out over violence? Is anonymity giving way to irresponsible action? And what should we expect as these networks deepen? There's a growing list of options being explored, and these explorers have dramatic and largely unknown stories to tell.
