Which of the following is a task officers typically perform at a crime scene?

Officers at a crime scene are primarily responsible for documenting evidence and compiling reports. This task involves meticulously collecting physical evidence, taking photographs, sketching the scene, and recording witness statements to ensure that all relevant information is preserved for investigation and potential prosecution. Accurate documentation is crucial for maintaining the integrity of the evidence, which can directly impact the outcome of a criminal case.

In contrast, launching public relations campaigns does not typically occur on the scene of a crime; this activity is more aligned with department outreach efforts. Conducting traffic safety checks occurs in a different context and is focused on enforcing traffic laws rather than crime scene management. Issuing warnings for minor offenses is also unrelated to the specific duties involved in processing a crime scene, as this task deals more with minor infractions outside of the scope of criminal investigations. Understanding the primary duties of officers at a crime scene highlights the importance of careful evidence handling and reporting in the law enforcement process.
