The global resurgence of the Black Lives Matter movement following the police murder of George Floyd in May 2020 has led to a rising demand for the abolition of the police. It follows years of deaths of black men and women at the hands of the police. But it is not just the police as individuals and as an institution that is responsible for these killings—there is a wider context for this situation that needs to be explained. Drawing not only on new data about police violence, interviews with leading voices in Black Lives Matter and beyond, as well as more than a decade of organising against police brutality, A World Without Police is the first book-length analysis of arguments for abolishing the police. It locates policing in its long-term historical context—particularly the relationship between policing and white supremacy and by binding the two—racism and policing—together, we can begin to imagine a world without either. ‘A World Without Police’ responds to a series of misconceptions: that police really do protect us, that the real problem is the militarisation of police, that the system is somehow ‘broken’, and that body cameras or ‘community policing’ schemes offer a silver bullet solution to police violence. Against such partial solutions, Ciccariello-Maher turns to equally concrete, real-world experiments in building communities without police, and communities in which police are no longer necessary, in both the US and beyond.
