Which of the following is true about the function of the HSIR?

The function of the HSIR (Homeland Security Intelligence Report) primarily revolves around highlighting threats and alerts to authorities. This aligns with its core objective of ensuring that relevant information regarding potential risks to national security or public safety is communicated effectively to the appropriate entities involved in responding to such threats. By focusing on threat awareness and timely alerts, the HSIR ensures that decision-makers and law enforcement authorities have the critical information necessary to protect the public and prevent security incidents.

In contrast, while reporting traffic incidents, providing intelligence assessments, and supporting legal procedures might be functions of other agencies or reports, they are not the primary focus of the HSIR. The HSIR is specifically designed to concentrate on significant threats and facilitating an appropriate response, making option C the most accurate representation of its function.
