Communication is a four way process. It involves the encoding section of the message to be communicated; the sending of the encoded message; the reception of the message (which should involve decoding of the message form and appearance); the feedback from reception (which at times is regarded as part of the reception point). When officers in a dispatch network are communicating to each other, the process may become a little more client oriented. An example of this is the ERMI process for communicating emergency incidences to a fire department. The following steps may represent the whole process and are likewise applicable to a law enforcement department. They include: Sense, Reach and Care (Sharpe & Sharpe).
For officers to act on an incidence they need to sense the incident and in so doing, they need platforms through which they can get information from external sources on incidents that have occurred. Telecom Switch having an Automatic IVR facility and Call distribution. When a victim in an emergency dials Emergency Response Centre; the call lands on Nortel Switch (PBX), which is the telecom switch (EMRI, 2011). Nortel Switch routes this call to the idlest officer. After this the fire response unit may need technology for reaching out to the affected victim of the incident. An example of such technology is the Computer Telephony Integration. CTI software helps in generating unique incident I.D. with the help of caller line identification wherever available and retrieves related information from Telephone directory database which pops up on the a screen (Sharpe & Sharpe).
Finally the fire department may choose to act on this information either by going to the scene of the incident with necessary equipment or identifying the incident as a fake call for action. Technology that can be used to refine information processing during interviews and interrogations in the criminal justice system may include remote access lie detecting machinery that can attempt to remotely read the same physical signals that are normally used to establish whether someone is lying or not during an interrogation. Another tool could be a tablet on which an interviewee can fill in important details about a criminal incident by manually writing on the tablet which is connected to a database that shall assess possible crime profile that relate to the data and sends this information to all relevant officers that are running the case. Generally we can see from the above examples that there is clearly room for immense innovation in this field towards delivering high standards of efficiency in the system (EMRI, 2011).
