What is the purpose of using a legend in a crime scene sketch?

The purpose of using a legend in a crime scene sketch is to explain any symbols used in the sketch. A legend is crucial as it provides clarity regarding the representation of various elements depicted in the sketch, such as the location of evidence, the position of victims, or any other pertinent details that may not be immediately recognizable. By defining symbols, the legend ensures that anyone reviewing the sketch can accurately interpret the information presented, which is vital for investigations, legal proceedings, and understanding the layout of the crime scene. This clarity can significantly aid law enforcement officials, investigators, and legal professionals in their work, ensuring that critical details are communicated effectively.
