Rhode Island Security Guard Practice Exam

When dealing with a crime scene, a security guard's primary responsibility is to secure the area and protect the evidence until the proper authorities arrive. This includes not touching anything, as any disturbance to the scene may compromise the evidence. Additionally, the security guard should not allow anyone besides the proper authorities to enter the scene in order to maintain the integrity of the crime scene. Therefore, all of the options listed (A, B, and C) are correct and the best course of action for a security guard to take when dealing with a crime scene.
