The discussion focuses on research in eight areas: (1) high-profile police activity, (2) aggressive law enforcement, (3) high-risk persons and places, (4) the police effect on guns and drugs, (5) problem solving case studies, (6) the police response to domestic assault, (7) police and communities, and (8) neighborhood crime watch programs. Findings suggest that unqualified conclusions about any police intervention in any area are premature. The most consistent findings are that efforts to achieve a strong police presence in communities are likely to result in some fear reduction but not necessarily in crime reduction. In addition, efforts to police aggressively through the enforcement of minor disorder and incivilities and through interrogations of persons that appear to be suspicious seem to be associated with lower crime rates. Findings suggest possibilities for efficacious and proactive prevention-oriented policing. However, further research and a debate about the proper role of police are needed. Notes and 77 references
