Also known as COMParative STATistics
CompStat is a process, not a computer program.
It is a process of applying four key principles that use
technology such as mapping, charting, and statistical analysis, as a tool for
targeting crime and applying officer resources based on the intelligence
gathered through the technology.
Principle 1: Timely, Accurate Intelligence
Intelligence must be accurate and timely to be effective.
Officers at all levels of the organization must have a precise
understanding of when types of crimes are occurring, how and
where the crimes are being committed, and who the criminals are.
Traditional policing tactics are directed at apprehending the
suspect. While criminal apprehension is an important part of
ComStat, it does not stop there.
ComStat requires the police to give attention to the social
and environmental situation that may be adding to or creating
Principle 2: Effective Tactics
Effective tactics must be developed after studying and
analyzing the intelligence. In order to bring about
permanent change these tactics must be comprehensive
flexible and adaptable to changing crime trends.
Solutions, as often as possible, should be collaborative,
including support units, other agencies and the public.
ComStat tactics encourage thinking outside the box and
mandate that every resource, both internal and external, is
considered when police respond to a problem.
Just employing tactics that displaces the crime problem
from one area to another is not acceptable.
Principle 3: Rapid Deployment
For decades, police departments have been driven by calls for
service and responded with limited resources in a reactive
manner. With ComStat, the police department is now armed with
vital information regarding emerging crime trends or patterns
that allow for a proactive strategic police response.
tactical plan is developed it is necessary to organize and put
into operation an assortment of personnel and resources.
By being able to quickly organize and deploy resources in the
field in a timely manner, the department is able to control the
crime problem before it becomes a crisis
Police can respond to problems using many forms, including
traditional uniformed or plainclothes officer response as well
as nontraditional stings and decoys.
By breaking down the barriers among the operating units, a
new spirit of cooperation and working together materializes and
enables the rapid deployment of resources.
Principle 4: Relentless Follow-Up and Assessment:
An essential element in any crucial operation is the need
to critically assess past tactics and review what worked and
what did not. One of the main differences between private
enterprise and the public sector is the bottom line of
positive returns. If a business implements an unsuccessful
strategy or provides an unacceptable level of customer
service, it is not long before it becomes a failed business.
Much like a business, the bottom line with ComStat is
To properly implement ComStat it is essential to record
data before and after the tactics have been deployed in
terms of reports of crimes, arrests made, and results
achieved. It is necessary to assess the results from the
establish the validity of the tactic;
know how the tactic worked and state clearly which elements
worked best, thereby allowing for the design of tactics
addressing future crime problems
