Weiburd emphasizes that place-based policing relies less on the characteristics of individuals that are related to their criminal behavior than upon the characteristics of small areas that facilitate opportunities for the commission of various types of crime. The police then work with members of the community in developing strategies that address crime-related factors associated with the defined area. Weisburd emphasizes that police strategies in place-based policing should not involve the police becoming an occupying force in the community. Police-community relations is advanced by working with community leaders in interpreting data and developing strategies to address community-based crime factors through crime prevention and mitigation. In discussing research on displacement of crime to adjacent areas, Weisburd notes that not only was there no evidence of displacement, there was evidence that crime also decreased in areas adjacent to the "hot spots." Possible reasons for this are discussed. Among the types of crimes discussed in place-based policing are street prostitution and street drug sales.
