There both pros and cons to the National Incident-Based Reporting System, NIBRS, which is way for police to report crimes.
Two positive aspects of this system include the collection of vast amounts of incident based data about crime, and the ability to examine the data in a variety of ways. Fifty-three data elements are amassed for crimes that fall into twenty-two categories. Officials can look at the nature of different offenses, study the characteristics of both the victim and the offender, and examine the value of stolen items. In addition, they can determine characteristics of those arrested for specific types of crimes.
There are also negative aspects to the NIBRS. One of those is that it only collects information about crimes that are known to the police, and another is that it only collects information on crimes that are included in the NIBRS list of serious criminal offenses.
