Organizing Crime in New York, 1930-50

Based on primary source documents, this historical study establishes the interconnections between private violence and political, social, and economic life in New York from 1930-1950. By describing and analyzing both the social world and social system of organized crime, Block provides a new perspective, one based on racial and ethnic stereotypes. The book provides a penetrating look at one of the most misunderstood aspects of American society, important for historians, criminologists and sociologists.
