This chapter focuses on community policing, a multifaceted innovation adopted by numerous police departments in the 1990s. Community policing involves proactive crime prevention; enhanced collaboration between police officers and neighborhood residents; and the acknowledgment that problems of social order (e.g. graffiti, vandalism, and public drunkenness) can make neighborhoods vulnerable to criminal elements and thus should be a priority for problem-solving collaborations between police, neighborhood residents, and other city agencies. Community policing is one of a number of urban programs ostensibly aimed at mobilizing citizens for civic engagement. However, there is scant evidence that community policing has the intended effect on civic engagement. There is also little evidence that community policing helps build social capital in terms of trust in neighbors or indeed trust in police.
