As the world becomes ever more unequal, people become ever more 'disposable'. Today, governments systematically exclude sections of their populations from society through heavy-handed policing. But it doesn't always go to plan. William I. Robinson exposes the nature and dynamics of this out-of-control system, arguing for the urgency of creating a movement capable of overthrowing it. The global police state uses a variety of ingenious methods of control, including mass incarceration, police violence, US-led wars, the persecution of immigrants and refugees, and the repression of environmental activists. Movements have emerged to combat the increasing militarization, surveillance and social cleansing; however many of them appeal to a moral sense of social justice rather than addressing its root - global capitalism. Using shocking data which reveals how far capitalism has become a system of repression, Robinson argues that the emerging megacities of the world are becoming the battlegrounds where the excluded and the oppressed face off against the global police state.
