 Crime and population figures show that Jews in New York committed crimes at a rate far below the average for the wider society.As described by sociologist Stephen Steinberg, less than a sixth of the city's felony arrests were Jews during the 1920s, when Jews constituted nearly a third of the city's population.As the 20th century progressed, Jewish-American mobsters such as "Dopey" Benny Fein and Joe "The Greaser" Rosenzweig entered labor racketeering, hiring out to both businesses and labor unions as strong arm men.
