This document discusses the importance of properly gathering, managing, and preserving evidence. It defines evidence as any material that can prove or disprove a matter under investigation. Evidence includes direct evidence like testimony, real evidence, documents, photos/videos, and expert testimony. Statements should be clear, concise, relevant, accurate, and attributable. Exhibits must be correctly labeled and their chain of custody documented to show they have not been tampered with. The integrity of evidence is critical, so it must be handled as little as possible.
