Sparked by the brutal police murder of George Floyd, the second wave of the #blacklivesmatter protest movement has surged across more than 100 US cities, spilling into Brazil, South Africa, Paris and London - to name a few of the primary sites of active resistance. This is a new movement, international in scope, with a disproportionately large section of young people - Black and white - using their own language and tactics to fundamentally challenge the whole range of racist institutions governing today's globalised world. Matt Clement's No Justice, No Police? The Politics of Protest and Social Change chronicles this movement as it continues to deepen and broaden.
