This is a one-hour lesson in which the dispatcher will listen to a 9-1-1 call where a fight is occurring at a popular bar in their city.  As a result of the fight at least one person is stabbed, and the scene is chaotic.  Dispatchers will use a computer to read through the lesson and learn best practice in interrogating callers reporting such an incident.  The lesson addresses the need to determine the exact location of the victim; transferring the caller to a secondary PSAP for Fire/EMS if within agency guidelines; caller, responder, and scene safety; ascertaining if weapons are present; obtaining a suspect description and travel route; and controlling the interview.
