This document outlines the essentials of writing police reports. It defines different types of reports and their purposes, including initial reports, supplemental reports, and attachments. Good reports are factual, clear, complete, and concise. They answer who, what, when, where, why, and how. Key components include the date, time, location, kind of call, and descriptions. The goals are to organize a police department's records, aid investigations and prosecutions, and document incidents from the initial response through any court proceedings.
