This is a one-hour lesson in which the dispatcher will listen to a 9-1-1 call where a caller reports an imminent fight at a restaurant.  Someone draws a gun and the scene quickly becomes chaotic.  Dispatchers will use a computer to read through the lesson and learn best practices in interrogating callers reporting such an incident.  The lesson addresses: determining the exact location of the person with a gun; ascertaining the weapon type and a description; remaining professional; controlling the interview; addressing scene safety, and determining how many people are present.
