What is one use of the outer perimeter?

The outer perimeter in a crime scene context serves an essential purpose, primarily related to maintaining the integrity of the scene and preventing contamination. One key function of the outer perimeter is to establish a controlled area where equipment and personnel can be organized effectively, which includes logging the equipment and materials used during the investigation.

While creating a log of equipment assets is a vital activity, it is primarily conducted within the secured area to ensure that all tools and items, such as evidence collection kits and forensic tools, are accounted for. Documenting these assets is crucial for maintaining chain of custody and for tracking the resources applied throughout the investigative process.

The other options, while they may pertain to various aspects of an investigation, do not align as closely with the primary functions of the outer perimeter. For instance, accommodating forensic technicians or providing a break area for officers focuses on personnel management rather than the direct purpose of the perimeter itself. Meanwhile, documenting witness interviews typically occurs within more confined areas, such as an interview room or a designated section of the crime scene, rather than at the outer perimeter.
