Radical criminology, closely linked to critical criminology, is a Marxist approach to crime that looks at criminality in its full social context and specifically considers how the ruling class uses crime to further its own interests. Radical or critical criminologists are interested in the creation of laws, the criminal acts themselves, the societal reaction to the acts, and the long-term consequences of both the acts and the reaction. For example, Stuart Hall carried out his famous study Policing the Crisis in which he investigated black muggings in the UK in the 1970s. He concluded that a moral panic was deliberately created in order to divide the working class and encourage people to blame immigrants and black people for unemployment rather than blame capitalism and the ruling class.
