American experience has been that any large influx of immigrants from any one country (or, presumably, language group or ethnicity) are, in the first generation - that is, the lives of those who were born abroad and came over here, likely to involve a good deal of "home style" justice, avoidance of the regular police and courts, and probably a degree of criminality or unorthodox ways of getting things done. However their children, born here, seem more acclimated to the American way and their grandchildren more so. So, while the first generation may have its own outlaws, their offspring are far more likely to be upright citizens.
