Crimmigration at the Local Level: Criminal Justice Processes in the Shadow of Deportation

In recent decades, authorities have adopted a number of programs that tether the criminal and immigration enforcement apparatuses in novel ways. This mixed methods case study assesses the impact of such programs on local criminal justice processes and outcomes in King County, Washington. Although the empirical research on the effects of such programs is scant, the emerging literature on legal hybridity suggests that the enmeshment of the criminal and immigration systems is likely to enhance the state's power to detain and punish. The quantitative results support this hypothesis: non-citizens flagged by immigration authorities stay in jail significantly longer than their similarly situated counterparts. Qualitative focus group interviews with prosecuting and defense attorneys identify four key mechanisms by which Immigration Customs and Enforcement detainers alter the incentive structure, impact decisionmaking, and extend jail stays for non-citizens. Together, these findings suggest that immigration law and the threat of deportation now cast a long shadow over local as well as federal criminal proceedings, and enhance penal pain for non-citizens. Implications of these findings for the crimmigration literature and research on the effect of citizenship status on criminal justice outcomes are discussed.
