The first question to be asked by dispatchers in call analysis is location of the crime or incident. After initial assessment and based on dispatcher training and experience with similar incidents, dispatchers may take steps to advise callers to take immediate action to protect themselves from injury. Specific, detailed information must be obtained from callers that will be required for responding units to plan their approach to the crime or incident scene and minimize dangers to responding officers and other public safety personnel. Dispatchers must immediately advise callers regarding the importance of not disturbing evidence. If dispatchers have time to communicate with callers, they may obtain additional information such as caller feelings and fears. Appropriate dispatcher procedures will facilitate criminal apprehension and prevent injury to responding officers, victims, and suspects. Specific types of information to be obtained by dispatchers are identified for many emergency situations, including car accidents, assault and battery, burglary and theft, abandoned children, child abuse, child molestation, criminal impersonation, homicide, arson, kidnapping, obscene phone calls, shoplifting, suicide, and vandalism.
