Which of the following is the purpose of the crime scene walk-through? To diagram and make necessary adjustments to scene layout To identify evidence to be protected and collected To provide context for other investigative procedures To isolate and interrogate suspects at the scene

The purpose of the crime scene walk-through is primarily to identify evidence to be protected and collected. During a walk-through, investigators conduct an initial survey of the scene to understand its layout, identify potential evidence, and determine the best approach for processing the scene. This step is crucial for ensuring that evidence is not overlooked or contaminated. While providing context for other investigative procedures can also be a part of the walk-through, the main focus is on identifying and protecting evidence.
