The literature on the criminal victimization of immigrants is less voluminous than that about immigrants as criminals; yet, it leaves no doubt that immigrants everywhere suffer a broad array of physical, financial and psychological injuries. Immigrants are victims of every kind of crime: murder, rape, robbery, assault, theft, fraud, and scams. They suffer at a higher rate of victimization than natives for major crimes. Their victimizers are usually other immigrants, co-ethnics who live similar life styles in the same communities. Several theories of criminal victimization fit well with these facts. Both routine activities theory and life-style theory explain the pattern of immigrants victimizing other immigrants. Immigrant enclaves may protect them from inter-group victimization (often hate crime) but not so much from intra-group victimization (the dominant pattern). The campaign to establish a global prohibition regime against human trafficking is not having substantial success because of the nature of the problem it is addressing. A fundamental problem with regard to the anti-sex-trafficking part of the campaign is that many countries permit legal prostitution.
