1.1 Background of the Study
The word Police is derived from the Greek word “Polis”, meaning that part of non-ecclesiastical administration having to do with the safety, health and order of the state. The Greek politeria, meant the art of governing and regulating the welfare, security needs and order of the city-state in the interest of the public. Although Police is derived from the Greek, it was the Romans who perfected the system. The Roman politia meant the same thing as the Greek Politeira. It was a symbol of power residing in central Authority (Nigerian Constitution, 2012).
During the duration of the Roman Empire, Police in Rome was organized from the ranks. There was the Roman Prefect which had under his control fourteen Magistrates, each responsible for a district and assisted by vigils who patrolled the streets, lictores who were law enforcement officers and station who were residents of the city blocks.
In Britain, Policing developed as a local affair with a role which has remained till now. That it is the responsibility of every person to maintain law and order. This role is rooted in history and common law tradition of Britain that each citizen had a duty to suppress crime and disorder within his area. Failure to do so entailed the payment of fines (Nigerian Constitution, 2012).
The burden of policing was placed on every adult citizen. It was an avocational obligatory policing, manifesting itself in the forms of thing man of the Saxon Police, the frankpledge in the South and East of England after the Norman conquest 1066 and later as the Parish Constable system after the enactment of the Statute of Winchester 1285 (Ojibah, 2016).
Before describing these systems in brief, it is relevant to observe that policing and police work did not start as a paid profession. It started as a noble, incorruptible profession with considerable responsibility and distinction. It was the Justices of the Peace system, which corrupted the Parish Constable System. When the first paid professional police force was proposed in Britain, it was strongly opposed by those who feared that such force would lead to repression and threat to the freedom of the individual and to democracy (Nigerian Constitution, 2012). The Police Force as we know it today went through three distinct stages before it became a profession. As Hewitt, W.A. puts it. At first the populace, though small was responsible for maintaining law and order. Then Justices of the Peace emerged on the scene to provide both the law and order and Justice at the bar. Then, in the present era, paid professional police were established to maintain law and order (Jerome, 2014).
Prior to carrying out this study, the criminal investigation department of 9th mile police station 9th mile area command are still using the manual system to handle criminal cases and other paper works which are prone to errors that cumulated to the followings:
More so, these problems made absolutely impossible for the law enforcement agency to contact crime to its barest minimum. Therefore, the problems is what should be done in order to create so much needed crime free society rather to contact crime to benefit from the potentialities of the law enforcement agency.
1.3 Aim and Objectives of the Study
The aim of this study is to design and implement a computerized Crime management system. The aims and objectives are;
1.4 Significance of the Study
The essence of Crime management system is to examine crime reports to see the rate of crime in the society. The analysis is used to determine how to manage the people in the police station. At any time during the fiscal year, Police officer may analyze the trends in the report to determine the best course of action.
1.5 Scope of the Study
This project is designed to support operation policing by providing crime related information investigation analysis, capabilities for deleting and apprehension offenders. It encompasses the relevant aspects of information management system such as data handling storage of data and cases, updating of information.
