The correct response focuses on the premise that supervisors should not always be granted access to a crime scene. While it's essential for supervisors to be kept informed about the situation, allowing unrestricted access can compromise the integrity of the scene. Crime scenes are often cordoned off to secure evidence and to maintain the proper chain of custody. Consequently, only individuals who are directly involved in the processing or investigation of the scene, such as first responders and designated investigators, should be given access until the scene is declared safe and secure.

Access to the crime scene is typically restricted to prevent contamination of evidence and to protect the scene from onlookers or unauthorized personnel. First responders are trained to collect evidence as part of their initial response, making their role crucial in maintaining the integrity of the scene before more specialized teams arrive. Witnesses may be asked to leave or remain at a designated safe area to make sure they are not influenced by outside factors or by the actions of others at the scene, which provides clarity and accuracy when gathering statements or evidence later on.
