discuss the evolution of police communication by developing a narrative timeline of milestones and the introduced auction of new technology. Your response should be at least 150 words long​

Answer:

When you call the police department on 9-1-1 you feel confident they will know the telephone number and address from which you are calling.

Explanation:

The Public Safety Dispatcher will ask questions and determine the priority of the emergency using the computer based telephone system. That information will then be entered into a computer aided dispatch (CAD) system. Using this computerized information the dispatcher will relay your need to the police officer in their vehicle. The police officer will receive this either on a PC based police radio or a mobile data computer located in their car. The Dispatcher will then locate the nearest officer by means of a GPS based vehicle locating system situated in the communications center. This system tracks the location of the field personnel throughout the City. The dispatcher can scan the map and locate the police officer closest to the location of the emergency. When the officer arrives he will determine if additional assistance is needed, such as the fire department or paramedics. The officer can then obtain that assistance via his hand held radio. All of this technology provides for a quicker response by emergency personnel, however it wasn’t always that way.Communication is vital to effective public safety. The first documented police communications was in Old England where the constable carried a hand bell or rattle, sometimes referred to as a ratchet. If the constable required assistance he would sound the ratchet to alert others in the area of his need. This was a very primitive type of communication with obvious limitations.In the late 1800’s when police officers started using vehicles in the United States, the only means of communication was a red signal light placed near major intersections. When an officer saw one of the lights on, they knew to call into the station for an assignment. Did you know that there used to be a light on the top of the Hotel Laguna in Laguna Beach for that exact reason?The Chicago Police Department updated their signal lights in 1870 with “Call Booths” called “Private Boxes”. Only an officer or “reputable citizen” would be issued a key that would grant them access to the private box. Inside was a telegraph that was set up with a device that looked like a clock with a bell on top. The officer would move the pointer on the telegraph to one of eleven specific choices (arson, thieves, forgers, riot, drunkard, murder, accident, violation of city ordinances, fighting, testline, fire) and pull a handle. This would send a message to police headquarters alerting them of the officer’s activity. In 1880, they added telephones to the call booths that linked the officer with the police department.The Detroit Police Department was the first city to utilize an “on the air” voice communication in 1928. Of course, they only had one police vehicle that had a radio; so all transmission went to “Cruiser Number 5”. While this facilitated the arrest of suspects, sometimes as the crime was being committed, there was a drawback. It was a one-way radio. The police department could talk to the officer, but the officer had to contact headquarters via a telephone or call booth. Even with its limitations, this new radio was truly a modern miracle.California joined the group in 1929. Police cars in San Francisco, Berkeley and Pasadena began to equip their vehicles with radio receivers. Again, these were one-way radios. The first two-way radio was used in Bayonne, New Jersey in 1933. This connected the Police Department to nine of their patrol vehicles.The next year the Federal Communications Commission (FCC) told the police departments that they could not use their radios for communications between departments. The FCC stated they must use the telephone or telegraph. This was definitely a blow to the progress of effective communications. However, in January of 1935, the FCC met with representatives of public safety and rescinded their decision.Now was the time for private vendors to realize the profits. General Electric, RCA and Motorola began manufacturing police radios. The cost for a police radio was approximately $735. While that doesn’t sound like much in today’s economy, it was more than the cost of the police car in 1937.It wasn’t until 1940 that the first statewide radio system was implemented by the Connecticut State Police. California also installed the first unattended repeater station in Contra Costa County.While the police radios were being fine tuned, agencies realized they still had a major officer safety problem. Beat cops did not have radios, and still had to use call boxes or telephones. When an officer left their vehicle, they were basically incommunicado.

To give officers meaningful direction and settle personnel disputes, police administrators must communicate clearly. Effective communication skills are crucial for accurately communicating the findings and conclusions of police research.

The fight against crime is also benefiting from facial recognition technology. By comparing suspects' faces to a database of hundreds of thousands of known offenders, law enforcement has used facial recognition to locate people wanted for crimes at large events, for instance.

The use of the telephone and telegraph in the late 1870s, the installation of police call boxes, the creation and use of the Bertillon system of criminal identification in the 1880s, and the creation and use of fingerprinting systems to aid in criminal investigations at the turn of the 20th century were all examples of technological advancements.
