What is not a reliable source of information at the scene of an active shooting?

Descriptions of suspects can be problematic in an active shooting situation for several reasons. Witnesses may be panicking, overwhelmed, or not paying close enough attention to details due to the high-stress environment. Their recollections might be influenced by their emotional state, leading to inaccuracies in the physical attributes or actions of the suspect. This can result in misleading or erroneous information that may complicate the response efforts or create confusion among law enforcement and responders.

In contrast, videos from the event provide visual evidence that can be analyzed for real-time information and detail. The numbers of victims, though fluid in rapidly evolving situations, are typically reported by medical personnel or officials who are equipped to handle and assess such information. Law enforcement radio communications are a reliable source as they are often coordinated and verified by trained personnel overseeing the incident. These sources are integral in shaping a clear and accurate understanding of the situation on the ground.
