Which of the following is NOT a responsibility of the first officers at the scene?

The responsibility of conducting a full forensic analysis falls outside the duties of the first officers at the scene. Their primary role includes securing the scene to prevent contamination, aiding in the preservation of evidence, assessing the situation, and ensuring that no evidence is disturbed. While they are involved in figuring out if a crime has occurred, locating and interviewing witnesses, and protecting the integrity of the scene, the in-depth forensic analysis of evidence is reserved for specialized CSI personnel and forensic experts who arrive later in the investigation. The first officers must ensure the scene remains intact for these professionals to conduct their thorough analyses without interference, highlighting the critical importance of their protective and preliminary investigative roles.
