Policing immigrants or policing immigration? Understanding local law enforcement participation in immigration control

As the United States has expanded its immigration control strategies, police participation in immigration enforcement has increased in scope and intensity. Local law enforcement agencies contribute to immigration enforcement in three key ways: through the direct enforcement of immigration law, through cooperation with federal immigration authorities, and through the everyday policing of immigrant communities. These enforcement approaches have consequences for unauthorized immigrants, and for the agencies and officers tasked with providing them police services. This article reviews local law enforcement practices and argues that future research should move away from an exclusive examination of police policies towards immigrants, to consider how the policing of immigrants actually occurs on the ground. Moreover, we argue that as long as discretionary arrests funnel removable immigrants into the deportation system, some immigrant communities will perceive policing as fundamentally unfair and discriminatory.
