Functions[ edit ] Crime analysis can occur at various levels, including tactical, operational, and strategic. Crime analysts study crime reports, arrests reports, and police calls for service to identify emerging patterns, series, and trends as quickly as possible. They analyze these phenomena for all relevant factors, sometimes predict or forecast future occurrences, and issue bulletins, reports, and alerts to their agencies. They then work with their police agencies to develop effective strategies and tactics to address crime and disorder.
In the most general sense, it is the polar opposite of reactive policing, which is characterized by randomized patrol, rapid response to calls for service, and retrospective investigations.
Instead of waiting for a crime to transpire, proactive policing entails striving to prevent crime before it ever comes to fruition. Strategically, the police can go about accomplishing this goal in a number of ways. Several of the most prevalent philosophies are described below. In the sections that follow, key readings are presented that highlight the evidence for and against both models.
From there, the discussion turns to hot spots policing—a proactive philosophy that certainly aligns with the problem-oriented approach but worthy of separate consideration. As proactive policing strategies have gained momentum throughout the last few decades, technology has become more sophisticated, which facilitates inter- and intra-agency communication as well as identifying problems within a community.
Consequently, a section is devoted to advances in technology and software. The growth and evolution of intelligence-led policing and the CompStat managerial model are presented in the sections that follow. Finally, a pair of techniques that encourage proactivity and have become very popular in recent years are offered: The models and techniques presented here are not meant to be an exhaustive list of proactive police strategies.
Instead, they represent some of the most prevalent approaches. Collectively, this research makes it abundantly clear that proactive policing is a broad concept that includes a variety of different approaches. No one approach is superior to the others—what works for one agency may not work for the next.
Nor should the police feel as though they are limited to selecting one philosophy or strategy; rather, many of them can be used together to complement one another.
On the whole, proactive policing is the antithesis of traditional policing methods. Rather than reacting to crime as it comes to their attention, the proactive movement calls for the police to do everything they can to try to prevent crime from occurring in the first place.
Walker agrees that the police should target minor offenses but suggests this would represent an altogether new model of policing rather than a regression to previous strategies, as Wilson and Kelling contends. Recently, Clarke and Stockdale, et al. Along these lines, Skolnick and Bayley recommends that the police get away from reactivity and, instead, come up with innovative strategies to reduce crime in neighborhoods that suffer from the highest rates of crime.
On the other hand, it can mean seeking to better understand crime problems in the community and coming up with innovative ways to address them. The following readings present these different orientations. Standing on the shoulders of community-based policing. Police Practice and Research 7.
Restoring order and reducing crime in our communities. The authors provide an in-depth discussion of what they believe to be the shortcomings of previous policing strategies. The new blue line.
They examine a number of police strategies used around the United States at the time, and they conclude that the police must develop innovative strategies that proactively deploy officers to specific neighborhoods suffering from chronic disorder. Applying economic evaluation to policing activity.PredPol has a precise definition of predictive policing.
For us and our customers, it is the practice of identifying the times and locations where specific crimes are most likely to occur, then patrolling those areas to prevent those crimes from occurring. In November , the National Institute of Justice, in partnership with the Bureau of Justice Assistance and the Los Angeles Police Department, held a Predictive Policing Symposium to discuss this emerging idea and its impact on the future of policing.
Law is change. People tend to think of the law as slow-moving, immutable and disconnected from daily life. And lawyers have a reputation of being cautious and resistant to change.
Crime mapping is used by analysts in law enforcement agencies to map, visualize, and analyze crime incident patterns. It is a key component of crime analysis and the CompStat policing strategy. Mapping crime, using Geographic Information Systems (GIS), allows crime analysts to identify crime hot spots, along with other trends and patterns.
