Here are two "live" discussions by radical activists introducing the issues of movement security: u.s. activist and author J. Sakai & long-time Canadian organizer Mandy Hiscocks. Sakai gave a workshop about the politics of movement security, sharing the results of typical incidents of both the movement's successes and the movement's failures in combating the "political police" or state security agencies.Hiscocks provides an honest and sobering appraisal of the practical challenge of State infiltration, and of how subsequent decisions played out in regards to the anti-G20 organizing and the repression that resulted.
