What characterizes a primary caller in an active shooter situation?

A primary caller in an active shooter situation is characterized by their direct experience of witnessing the incident. This firsthand account is crucial because it provides law enforcement and emergency response teams with immediate and reliable information about the situation. Witnesses can give specific details about the shooter's location, behavior, and the number of potential victims, which can significantly affect the response strategy. Their observations help to confirm the authenticity of the threat and can guide responders in ensuring the safety of individuals in the vicinity.

While others may relay hearsay or reports from second-hand sources, the information provided by the primary caller is generally viewed as more credible and urgent. This clarity is vital during chaotic situations where accurate and timely information is necessary for effective action. In contrast, those who are uncertain about the situation or who have merely heard rumors do not offer the same level of actionable intelligence.
