This is a one-hour lesson in which the dispatcher will listen to two 9-1-1 calls. In the first call, a car was driven into the front of a bar. In the second call, a person reports an armed home invasion robbery.  Dispatchers will use a computer to read through the lesson and learn best practice in interrogating callers reporting such incidents.  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.
