- Crime reports
- Field Interview cards

- Computer Aided Dispatch data
- Statewide Integrated Traffic Reporting System (SWITRS)
800.3 CRIME ANALYSIS FACTORS
The following minimum criteria should be used in collecting data for Crime Analysis:
- Frequency by type of crime
- Geographic factors
- Temporal factors
- Victim and target descriptors
- Suspect descriptors
- Suspect vehicle descriptors
- Modus operandi factors
- Physical evidence information
800.4 CRIME ANALYSIS DISSEMINATION
For a crime analysis system to function effectively, information should be disseminated to the appropriate units or persons on a timely basis. Information that is relevant to the operational and tactical plans of specific line units should be sent directly to them. Information relevant to the development of the Department's strategic plans should be provided to the appropriate staff units. When information pertains to tactical and strategic plans, it should be provided to all affected units.
