Communities and police face numeruous ever-changing challenges in fighting crime. By sharing and learning from other cities experience, police/community partnerships will be better able to successfully deal with these challenges. In this project, advanced algorithms from computer science research in Case-based Reasoning (CBR) are used to identify for police officials and citizens similar communities in terms of economics, crime, police resources, etc., helping them develop colleague networks. Increased support of information flow among police departments will help them learn from each others experiences, leading to: 1. provide a pool of innovative strategies; 2. help to avoid previous failures; 3. make proactive measures more likely by helping officials to anticipate new problems and trends; and 4. encourage strategic, long-range thinking and planning, rather than mere tactical planning.
