The Crime Analysis Unit falls under the Operations Division and is primarily responsible for the identification, analysis, and dissemination of crime and offender information to patrol and other divisions of the department to assist in the goals of crime prevention, criminal apprehension, and resource allocation. Incident data is studied to determine “who is doing what to whom” and to assist in the identification of any existing crime pattern(s) or series. This type of information is distributed to all members of the department by means of crime bulletin notifications, crime series forecasts, wanted flyers, and hot sheets. Geographic Information Systems (GIS) is used to display a visual of the incident locations and aids in the identification of hot spots and/or denser crime areas which is oftentimes useful in determining where to focus extra patrol efforts.
CAU also works closely with the Detective Bureau by providing a list of possible suspects that match certain criteria on a case-by-case basis in order to clear cases involving homicide, robbery, burglary, aggravated assault, grand theft, sex crimes, and identity theft. Some of these factors include but are not limited to a suspect’s physical description, vehicles owned/associated with, parole/probation status, prior criminal history as it relates to the investigation, and probable locations for contacting the individual.
The Crime Analysis Unit also conducts intelligence analysis for the gang and narcotics units by focusing on the relationships between subjects and the criminal organizations they affiliate with. The analysis of statistics is also an essential role of this division. The unit provides regular updates to command staff regarding changing trends in violent and property crimes, response times, traffic data, etc. This information is used by staff in consideration of personnel deployment changes as well as special projects/operations when targeting areas of concern.
The Rialto Police Department subscribes to the concepts of "evidence-based policing." "Evidence-based policing" is the use of the best available research on the outcomes of police work to implement guidelines and evaluate agencies, units, and officers. It suggests that just doing research is not enough and that proactive efforts are required to push accumulated research evidence into practice through national and community guidelines. These guidelines can then focus in-house evaluations on what works best across agencies, units, victims, and officers.
