Computer-aided dispatch records can show when a call was created, dispatched, acknowledged, updated, and closed. They are often useful when narrative reports provide only a summary.
What a CAD record may contain
Systems differ, but an event record may include call type, location, unit assignments, status changes, timestamps, dispatcher notes, and cross-referenced incident numbers. Codes may require an agency legend to interpret.
Ask for the event detail, not only a log
A daily call blotter may contain less information than the event-level CAD record. Identify the particular incident and request the event detail, unit history, comments, and code definitions when maintained.
Identify the system owner
The responding police agency may use a city, county, regional, or contracted dispatch system. If the department says it does not possess the record, ask which communications agency handled the event.
Use CAD data carefully
CAD entries reflect information entered during a developing event and may contain errors, shorthand, or later updates. Compare them with audio, reports, and other contemporaneous records before drawing conclusions.
