Consensus has not been reached on whether a relationsip exists among violent crime, fear of crime, and firearms ownership. The questions addressed here are how, if at all, the neighborhood environments of urban blacks and whites affect their patterns and levels of gun ownership, what their attitudes are toward gun regulation, and whether there is a relationship between gun regulation attitudes and firearms ownership. Data collected through a mail questionnaire from white and black residents of high and low homicide risk neighborhoods in Detroit were used to test the questions. Results indicate, for the most part, that blacks and whites hold different attitudes toward gun regulation, that gun regulation attitudes affect gun ownership patterns, and that only in one instance did neighborhood environment explain gun ownership relatively well.
