This document discusses principles of police report writing. Reports can be written by hand, typed, or filled into a form and will be read by supervisors, prosecutors, attorneys, reporters and officials. Reports provide information for further investigation, record details of incidents, demonstrate professionalism, build legal cases, and supply statistics. When writing, officers must reconstruct past events, consider different witness accounts, remain objective, and document evidence collection attempts factually without guesses. Good report writing requires skills like orienting oneself, pacing distances, and accurately describing appearances, interviews, and details.
