The dramatic increase in both lawful and unauthorized immigration in recent decades produced a groundswell of research on two questions: (1) Does immigration increase violent crime? and (2) What policy responses are most effective at addressing unauthorized immigration (e.g., sanctuary policies, deportations, etc.)? For the most part, these bodies of work have developed independently, and thus we know little as to whether the insights from one inform the other. This Article fills this gap by first reviewing both areas of research and then triangulating shared findings between them. In doing so, we focus on three contemporary immigration policies: (1) increased deportation; (2) “sanctuary” policies, and (3) “amnesty” laws. Our review provides little evidence to suggest that immigration increases the prevalence of violence. For this reason, policies aimed to enhance public safety by reducing immigration are unlikely to deliver on their crime reduction promises.
