Answer:
National Incident-Based Reporting System (NIBRS)
Explanation:
NIBRS is used by the law enforcement agencies in the United States for collecting and reporting data on crimes. It is a way of categorizing or organizing the crimes committed throughout the United States.
The NIBRS records offences based on the category they fall in their classifications. The sole aim of the NIBRS is to improve the overall quality of crime data collected by law enforcement agents.
Since the NIBRS contains different categories of offences with details, it will be best for Wally to use the NIBRS in order to access the incident account and the information of the victim and offender.
