    Although homicide and robbery share a lot of ethical consideration they also have different elements for the investigator to follow to obtain a successful investigation and prosecution. The elements of an unlawful homicide is called the corpus delicti which is the basic facts collected establishing that a crime has been committed and someone is responsible for that crime. In order for the judge to hand the case over or for the prosecutor to obtain an indictment each element the investigator must provide evidence for each element of the corpus delicti. There are two elements for unlawful homicide which are; ruling out suicide, natural causes, and accident, by establishing it was a homicide and there is a person responsible for the homicide. This must be obtained and in the knowledge of the investigator, evidence technician, and criminalists.

    Bus 1203B-03: Law Enforcement Operations And Report Writing

    There are many different ways that the media can affect the way crime is looked at. Many of the media companies will talk about increases in crime, but will only target the few specific crimes that have slightly increased but will not touch base on all the crime statistics that show decreases in other areas. The media has a very smooth way of focusing on violent crimes above all others. Homicides and violent crimes receive a much higher amount of attention than any other crimes. If there was a bunch of minor traffic violations and a few tickets given out for minor things and one assault charge the only thing that would be brought up in the media is the assault charge.…

    The search for physical evidence at a crime scene must be done thoroughly and followed by the protocol. How the criminalist will decide to execute the crime-scene investigation depends on the size and the locale of the area, as well as on the actions of the suspect(s) and victim(s) at the scene. It must be considered that physical evidence can be anything, from a massive object to a microscopic trace, however, some evidence are clearly visible but others need to be examined in the laboratory in order to be detected. Physical evidence must be processed in a way so as to prevent any change from happening between the time that was collected on the crime scene and the time it is received by the laboratory. When collecting physical evidence from a scene, any criminalist must be aware of the fact that recovery of one type of evidence can destroy another.…

    Court Report

    The basic division in the structure of criminal courts is between the lower criminal courts – the local courts, Children’s court and Coroner’s court – and the higher criminal courts – the District Court and the Supreme Court. In observing proceedings at the Local, District and Supreme Courts over a period of three days a number of aspects of the criminal justice system were made apparent. The administration, processes and practices of the criminal trial are extremely varied dependent upon the level of criminal court being observed. The distinctions between the workings of the two courts revealed a number of the differences between summary proceedings and trial upon indictment. The cases observed served to provide evidence for the “two tiers of justice” argument. Also the role of the judiciary was perceived as being particularly interesting especially the high level of discretion that they held in the Local Courts and even to an extent in the District Court primarily when there was no jury present.…

    Synopsis of the New Police Report Manual

    A Field Training Officer (FTO), Rutledge (Author), is on patrol with a patrol officer. He has to type his first police report and is not doing a good job. His officer was disappointed at what he had read in his report; he’s going to show the rookie how it’s done. The officer’s report was not only 50% longer, but full of jargon. The rookie cop stated, “Why do we write like that?” “Because that’s the way we’ve always done it,” replied the officer. After years of being a cop and writing real police reports, Rutledge became a prosecutor. After numerous trails, Rutledge was still boggled at the way police reports were written. So he decided to ask other people in the field of criminal justice and the explanation was the same, “that’s the way we’ve always done it, and no one has bothered to ask why.” The problem is the style is all wrong and everyone is trained to write this way. Rutledge states, “Police reports should be written in the way that you would normally communicate information.” Police reports need to be correct, unclouded and believable otherwise law enforcement personnel will undoubtedly lose the case. During a trial police reports are designed to help the officer out not the criminal; consequently, the court has trouble understanding the reports due to the style, too much jargon, excess big words, and awe and not enough communicating what you know. Rutledge states, “Work smarter not harder.”…
