In the context of police field notes, which statement best describes their role?

• A. They document observations for later investigation
• B. They are the sole legal document
• C. They replace all incident reports
• D. They are used only for training

Answer: (A)

Field notes are meant to capture what an officer observes and does in the field, serving as a memory aid and a factual base for later investigation. Their primary role is to document observations, times, locations, descriptions, statements, and actions so they can be reviewed when compiling reports, reconstructions, or ongoing inquiries. They provide detail that supports subsequent official documentation and investigative work, rather than standing alone as the final legal record.

They are not the sole legal document—the formal incident reports are the official records, and field notes feed into those reports rather than replace them. They’re also not only for training; while they may be used in training, their main purpose is to support investigation and accountability by preserving contemporaneous observations and impressions.
