The book blends discussions of settler colonialism, policing and surveillance, with a detailed exposé of current security practices that targets Indigenous movements. Using the Access to Information Act, the book offers a unique view into the extensive networks of policing and security agencies. While some light has been shed on the surveillance of social movements in Canada, the book shows how policing agencies have been cataloguing Indigenous land defenders and other opponents of extractive capitalism, while also demonstrating how the norms of settler colonialism structure the ways in which police regard Indigenous movements as national security threats. The book examines four prominent case studies: the long-standing conflict involving the Algonquins of Barriere Lake; the struggle against the Northern Gateway Pipeline; the Idle No More movement; and the anti-fracking protests surrounding the Elsipogtog First Nation. Through these case studies, we offer a vivid demonstration of how policing agencies and the criminal justice system are central actors in maintaining settler colonialism. The book raises critical questions regarding the expansion of the security apparatus, the normalization of police surveillance targeting social movements, the relationship between police and energy corporations, and threats to civil liberties and collective action in an era of extractive capitalism and hyper surveillance.
