Crime science is multidisciplinary and recruits every possible skill towards its cause. Within crime science, crime scientists look for patterns in crime in order to find ways to disrupt it. Today, the application of crime science is seen as having the potential to create new tools to make problem-oriented policing (POP) possible. To tackle crime intelligently and be less reactive to crime, police or crime analysts will become more important requiring the qualities of application, skepticism, and persistence. This manual is intended for police/crime analysts who are accustomed to providing information needed to support police operations. The manual builds on the analyst’s experience to prepare them for a different analytic role as a key member of a problem-solving team. The manual prepares the analyst for this new role by offering a basic knowledge of POP and the related fields of environmental criminology and situational crime prevention which are encompassed by the new discipline of crime science. The manual presents 55 steps in becoming a problem-solving crime analyst divided into 8 sections: (1) prepare yourself; (2) learn about problem-oriented policing; (3) study environmental criminology; (4) scan for crime problems; (5) analyze in depth; (6) find a practical response; (7) assess the impact; and (8) communicate effectively.
