How does local law enforcement, with the aid of city and county governments, respond to racialized immigrant threat through policy implementation, namely, through adoption of intergovernmental agreements? More specifically, how is this response tailored for Latino immigrant communities, particularly in new destination communities? Across the country, scholars, activists, and politicians note the increasing use of local law enforcement to implement federal immigration enforcement measures through intergovernmental agreements, emphasizing the disproportionate impact on the Latino, more specifically the foreign-born Mexican, population. One such intergovernmental partnership is the 287(g) agreement between local law enforcement and Immigration and Customs Enforcement. Yet little is known about the process through which counties adopt, implement, and maintain such intergovernmental partnerships and the state actors that make it all possible.
