Jewish-American organized crime was a reflection of the ethnic succession among gangsters, which has tended to follow the immigrant waves in the United States: English, German, Irish, Jewish, Italian, Asian and Latino. Ethnic involvement in organized crime gave rise to alien conspiracy theories in the US law enforcement community, in which the conception of organized crime as an alien and united entity was vital. The involvement of a small percentage of recent immigrants in organized crime created a lasting stereotype of devious immigrants corrupting the morality of native-born Americans.
