Canter argues that information about location of a crime scene represents their personal experience of their environment. Therefore, the location of the crime scene can be used to infer; where the offender is based and the offenders interests, employment and relationships. There are a number of cases which have successfully demonstrated the use of geographical profiling. For example, the case of John Duffy the railway rapist was successful. They began to plot the rapes and then the murders and then used geographical information to try to work out where he was based.
Black Hat or White Hat There are multiple examples of people convicted of major crimes working with law enforcement to help convict other people doing similar crimes. In fact, the perpetrator of the ZZZZ Best case was released from his sentence because of all the good he was perceived to have done against subsequent frauds. Is using convicted criminals to fight future crimes a good idea? Explain with an example. Disc7 Accounting Black Hat or White Hat Student Name: Institution Name: Abstract A criminal investigation involves seeking, collecting, and gathering evidence for a criminal case.
Ucas personal statement draf 1 Criminology is a subject that will always be relevant in society because Criminology looks at the different aspects such as why criminal offences are committed within society. Could it be the impact of primary and secondary socialisation on each individual? Another question that I feel is important is the criminal justice system effective? In my opinion I feel that these two vital questions are fundamental to understanding why crimes are committed. My interest into the study of crime emanated from the television series “The Bill” I understand the hyper reality and fictionalization of television programmes but this became the starting point of my curiosity.
Offender profiling is the establishing of a hypothesis to identify a criminal via examining the evidence accumulated from a crime scene, this helps authorities narrow down searches for individuals with traits that correlate with signatures of the crime, one such noted profiler was Robert Ressler. In discussing the FBI approach to offender profiling, it is essential to draw focus on the methodology developed by Ressler and how it is utilised by authorities in addition to its strengths and limitations. In this context offender profiling is used when examining crimes involving serial murders of a sexual nature. The FBI profile emerges from stages, the process begins with what is termed the Assimilation Stage. Evidence of the crime scene is obtained, this would include photographs or an in person examining of the scene, a profile of the victim (including their pathology reports), witness statements and DNA analyses of the victim and the offender.
The book does a great job of identifying the underlying issues that this family suffers from. It does an even better job of showing how criminal behavior can be passed down from generation to generation along with how ones environment can affect their criminality. This violent and criminal cycle is not just limited to the Bosket family but is seem as well as repeated in many poverty stricken areas around the world daily. My hopes are that since the underlying issues of the Bosket family were brought to the surface, maybe this information can be used to help future individuals who are plagued with the same
Investigative notes are a permanent written record of the facts of a case to be used in further investigation, in writing reports and in prosecuting the case (Hess, 2010). Taking notes is no stranger to police officers at a crime scene; many officers find this strategy to be very helpful determining the guilt or innocence of an individual. Gathering notes from witnesses as soon as possible after receiving a call to respond and continue recording information as it is received throughout the investigation, “witnesses are important sources of information regarding crimes committed in their community” (Hess, 2010). Note taking is supposed to benefit the investigation, but how information is obtained—whether the officers establish good rapport or not—can greatly influence investigative success. When taking notes officers must learn to keep it short and abbreviated, and at the same time understandable for not only you to read, but if you become ill, injured or deceased, others must be able to read and understand your notes.
Here we will be discussing the potential advantages of using Raman spectroscopy and fluorescence spectroscopy, compared to the current destructive techniques being used in body fluid analysis. Introduction The ability to detect body fluids at a crime scene is very important in the field of forensic science. Body fluids give insight into the nature of the crime, as well as identify those present at the crime scene. Further DNA analysis of these fluids helps authorities identify the victim and assailant, and provides evidence that can be used to convict the perpetrator. The most common types of body fluids found at crime scenes are blood, semen, and saliva (Virkler and Lednev, June 2008).
Criminal Profiling: Serial Killers Starsha Brown Walden University The Nature of Crime & Criminology August 4, 2015 Introduction Criminal profiling is vital when researchers are trying to identify the key characteristics of a serial killer. Profiling will assist investigators with identifying the types of serial killers as well as decreasing the numbers of victims. The more information that is gathered about the serial killer, the quicker the apprehension of the offender will be. In criminal trials, criminal profiles paint a clear picture of the dynamics that surround serial killing and the intense fantasies that provoke serial killers. In this paper, I will discuss the fundamental behaviors and factors of serial killers (Paul Rowles and John Wayne Gacy) that criminal profilers should be aware of in future serial killer cases.
It highlights differences between the behaviours of criminals and consistencies within the behaviour of individual offenders. Ainsworth also points out that the US ‘crime scene analysis’ has been very influential as it has been successfully used in other countries e.g. Canada and the Netherlands. It helps the police predict the level of violence and the timing of future crimes. Douglas (1981) conducted a review for the FBI on the costs and benefits of profiling.
Deception Deception is used by law enforcement to help them gather facts or the truth about a crime committed. Deception is one of the most used tools in investigation, interrogative, and the testimonial process and some believe that telling a little “white lie” to catch a criminal is not a problem. Criminal activities are increasing at a fast rate in the United States and law enforcement needs some type of help in catching a criminal and sometimes saving a life. One of the questions posed by some not in law enforcement could be if it is ethical to lie to obtain the truth. This paper will discuss that topic along with if it is a conflict between the code of ethics and how law enforcement is conducted.
