 Anarchist violence appears as the violence of an individual against the state. It is easy to see why such violence would be characterized as terroristic and criminal. For an individual to declare war against the state and take action to disrupt the state is criminal. And thus anarchists have also been interested in a critique of crime and criminality—arguing that it is the law and the legal system that creates and produces crime and criminality. This critique was advanced by Kropotkin as early as the 1870s, when he called prisons “schools for crime”. Similar ideas are found in Foucault and in more recent criticisms of mass incarceration. Contemporary anarchists will argue that mass incarceration is an example of state power run amok.
