Unofficial investigators should not: • Allow intermediaries to become involved in the investigation beyond their mandated roles and capacities; • Provide intermediaries with more information than necessary; • Allow intermediaries to intimidate or coach victims/witnesses; or • Work with former members of the military or individuals of the same ethnicity as the perpetrators (if possible). 72 2.2.6 Logistics of Documentation Although not always possible, it is important to try to be prepared when arriving at a crime scene and documenting information. Without the necessary equipment and expertise, an information-gathering exercise may result in missed opportunities and compromise the investigation. Therefore, plan and prepare all activities to the greatest detail and extent possible. With regard to the logistics of documenting a crime scene, it is important to: 1. Know the area: determine whether the area is known for the prevalence of kidnapping, land mines or other dangers, determine food and water sources, and whether certain health issues affect the area. 2. Map landmarks, plan routes and determine points for contact. 3. Be self-sufficient. This includes carrying food and water, as well as essential basic equipment: • Consent forms; • First aid kit; • Flares; • Flashlights and extra batteries; • Paper bags; https://www.icc-cpi.int/en_menus/icc/legal%20texts%20and%20tools/strategies-andguidelines/Documents/GRCI-Eng.pdf. 72 Foreign and Commonwealth Office, International Protocol on the Documentation and Investigation of Sexual Violence in Conflict, 44 (2014). 55
