Molly T. O'Brien (Australian National University) has posted Exploring the Group-Identity Function of Criminal Law on SSRN. Here is the abstract:
In every country where the question has been studied, incarceration rates for members of some minority groups greatly exceed those for the majority population. The problem of disproportionate incarceration is not therefore a problem of one ethnic group or one set of historical circumstances. It is a human problem that is fundamentally connected to social group identity. This essay conducts a preliminary exploration of the role that criminal law serves in group-identity formation. It suggests that building a common or super-group identity may be necessary to achieve greater justice in increasingly multi-ethnic and mobile societies.
