In When Riot Cops Are Not Enough, sociologist and activist Mike King examines the policing, and broader political repression, of the Occupy Oakland movement during the fall of 2011 through the spring of 2012. King’s active and daily participation in that movement, from its inception through its demise, provides a unique insider perspective to illustrate how the Oakland police and city administrators lost the ability to effectively control the movement. Drawn from King’s intensive field work, the book focuses on the physical, legal, political, and ideological dimensions of repression—in the streets, in courtrooms, in the media, in city hall, and within the movement itself—When Riot Cops Are Not Enough highlights the central role of political legitimacy, both for mass movements seeking to create social change, as well as for governmental forces seeking to control such movements. Although Occupy Oakland was different from other Occupy sites in many respects, King shows how the contradictions it illuminated within both social movement and police strategies provide deep insights into the nature of protest policing generally, and a clear map to understanding the full range of social control techniques used in North America in the twenty-first century.
