Incident report

An incident report is an agency's written record of a reported or investigated event. It may describe statements, observations, actions, and classifications available when the report was prepared. A report documents information received or developed by the agency; it does not, by itself, establish that every allegation is true or that someone is guilty.

What readers may find in a report

A report commonly organizes information about when and where an event was reported, what people said happened, and what the responding or reporting officer did. Structured fields can identify an event type or alleged offense, while a narrative supplies context that the short category cannot convey.

The FBI's NIBRS manual describes the incident report as a common starting point for collecting crime-reporting facts. This explains why selected report fields may later appear in statistical files. It does not mean that every incident report is a criminal offense or that the public receives the complete underlying report. FBI manual, section 2.

An incident report does not always follow an in-person response. Honolulu, for example, provides a process for certain nonemergency reports initiated online and completed with police contact by telephone. The department's eligibility conditions are local, but the example shows why report counts and dispatch counts can differ. Honolulu police reporting process.

Example

Hypothetical example: A resident discovers that a bicycle is missing from a shared storage area. An officer records the resident's account, the time the bicycle was last seen, its description, and the fact that the exact time of disappearance is unknown. The report receives a case number.

Three days later, the resident finds a receipt containing the serial number. The agency adds that information in a supplemental report. The original report and supplement concern the same reported loss, rather than two separate thefts.

A public summary might show only “theft” and the report date. That abbreviated entry does not reveal the uncertain occurrence time or all the information added later. The full narrative and supplements, where available, provide a more complete account.

Common confusion

A dispatch log records coordination of the response. An incident report provides a separate account of the event. Some calls end without a report, and some reports are created without a dispatch.

A report is not a court judgment. An allegation, suspect identification, arrest, charge, and conviction represent different stages. Naming someone in a report does not establish the final result of any prosecution.

An initial report is not always the complete case file. Later witness interviews, corrections, and supplements can change the available account. An early summary may remain accurate about what was reported then while being incomplete about what was learned afterward.

Reading dates, status, and availability

Distinguish the occurrence date from the report date. A theft discovered on Tuesday may have happened during an earlier interval, while the report itself may be submitted Wednesday. Grouping by each date answers a different question.

Also distinguish the report's classification from its case status. A theft report can remain recorded as a theft while the investigation is open, inactive, or closed under local rules. Status alone does not explain whether the offense was statistically cleared.

Access depends on the relevant agency's disclosure process. Honolulu's records page, for example, distinguishes obtaining releasable reports from receiving a verification letter in certain circumstances. A searchable public summary and a requestable report are therefore different forms of access. Use the issuing agency's current records instructions to identify the document, available versions, and release conditions.
