Some commentators have characterised so-called ‘no-go’ areas as sites in which the
exercise of authority is prevented. Here we suggest that many such spaces are produced by
state, policing and citizen repertoires that aim to minimise the costs and risks of engaging,
supporting and servicing such spaces and their populations. In this article we locate
strategies of public spending, policing and political action that offer a governing logic in
which neighbourhoods are essentially subtracted from the constitution of the city. During
such designations the assurances of citizenship, vitality of civic institutions and presence of
policing may be partially or wholly suspended. We present a framework for the
identification of such strategies in which these forms of social, political and spatial exiting
are described as being autotomic in nature – spaces that are ejected in order to avoid losses
or further damage to the body politic of the city in ways akin to the response of certain
animals that protect themselves from predation by shedding a limb or body part. This term
adds force and depth to assessments of the ways in which both temporary and more
sustained exits by policing, management and state servicing are designed in order to avoid
responsibility over, or engagement with, spaces that are deemed a threat in order to
maintain the integrity of the remaining, included city
