As part of a burgeoning interest in analyses of the colonial roots of contemporary state practices, scholars in the field of International Relations have sought to “decolonize” the study of security. To do so, they have examined how the methods of control and repression that were first developed in the colonies were brought back to the metropole to lay the foundation for the carceral security state. However, by framing the analysis around the concept of the colonial boomerang, they have largely undertheorized how racial and colonial violence historically also played out across the centers of the European metropole.
