A riveting primer on the growing trend of surveillance, monitoring, and control that is extending our prison system beyond physical walls and into a dark future—by the prize-winning author of Understanding Mass Incarceration “James Kilgore is one of my favorite commentators regarding the phenomenon of mass incarceration and the necessity of pursuing truly transformative change.” —Michelle Alexander, author of The New Jim Crow In the last decade, as the critique of mass incarceration has grown more powerful, many reformers have embraced changes that release people from prisons and jails. As educator, author, and activist James Kilgore brilliantly shows, these rapidly spreading reforms largely fall under the heading of “e-carceration”—a range of punitive technological interventions, from ankle monitors to facial recognition apps, that deprive people of their liberty, all in the name of ending mass incarceration. E-carceration can block people’s access to employment, housing, healthcare, and even the chance to spend time with loved ones. Many of these technologies gather data that lands in corporate and government databases and may lead to further punishment or the marketing of their data to Big Tech. This riveting primer on the world of techno-punishment comes from the author of award–winning Understanding Mass Incarceration. Himself a survivor of prison and e-carceration, Kilgore captures the breadth and complexity of these technologies and offers inspiring ideas on how to resist.
