merging in regular use being deployed in various applications such immigration border control, forensic systems and payment authentication. The use of biometrics for people identification is considered as a vital tool during forensic investigation. Forensic science can be defined as the method of gathering, analysing and interpreting past information related to criminal, civil or administrative law. This includes the perpetrator identity and the modus operandi [30]. Forensics involves several processes including: investigation, evaluation, forensic intelligence, automated surveillance and forensic identity management [39]. Forensic analysis is performed in order to conclude further evidence to exonerate the innocent and corroborate the identity of the perpetrator through …show more content…

Many biometric features can be used in forensic analysis such as face, ear [2], speech and gait [8]. However, the availability of biometric features for identification is limited to forensic experts depending on the nature of the crime scene and perpetrators. Expert witness is usually based on a body of knowledge or experience provided by an individual who is formally qualified and broadly experienced in a particular domain. There are considerable factors contributing to establish the credibility of an individual acting as an expert including educational qualifications and relevant experience. However, qualitative and descriptive-based expert opinions are argued to be insufficient and less credible [6, 36, 16] in contrast to empirical-based statements which are gaining wider acceptance. The admissibility of forensic evidence is administered by the court juries or the legal system depending on the juridical framework of the country. In the United States, the Daubert standard was conceived in 1993 [17] when the Supreme

    Therefore, the criminal justice system relies on other nonscientific means that are not accepted or clear. Many of forensic methods have implemented in research when looking for evidence, but the methods that are not scientific and have little or anything to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011). Defense experts are required to help the defense attorneys defend and breakdown all of the doubts in the prosecutors scientific findings in criminal cases. Scientific information is integral in a criminal prosecution, and a defense attorney needs to have an expert to assist he/she in discrediting the prosecution (Giannelli,

    Forensic science has paved the way to a new world of technological advancements in solving crime, through DNA analysis, new technology such as M-Vac, improving systems such as CODIS and other investigative methods. As forensic science technology advances, the chance of an individual being able to commit a crime and walk away free without leaving any trace of evidence will lessen.

    Overall, though, I believe that Stein is the closest scholar here-mentioned to have accounted for the explanation behind these controversies. The main mistake made by many modern scholars lies in the planning and the research – too much effort is spent on seeking to explain this opposition between the Proculians and the Sabinians in terms of two internally coherent law schools which differ entirely and have held controversies stemming from a specific occurrence. I have personally, as a student of the Roman law, found it difficult in reading the sources and differing theories from scholars to do just this – because, as Scarano Ussani stated, nowhere, in the mass of research that has been done, have any definitive results been reached. As afore-mentioned, I ruled out the political explanation for the purpose of answering this question, and the social explanation does not add a great deal to the debate for me. The theories supporting the social standpoint as addressed in this essay are among the worst for choosing to ignore many of the hard facts in order to make their theory fit better. This leaves only the philosophical and methodological explanations. The philosophical explanation is a reasonably sound one, although as explored above, I do believe that its significance has been largely exaggerated. There is no doubt over the fact that philosophy has played an influential role - even if you only look at Gaius’ ius gentium which contains a certain level of Stoic influence, but as mentioned above there are major differences which have been overlooked slightly in those arguments. The methodological explanation is another seemingly logical one, and the most reliable of all theorems explored in this essay, in my opinion, as it i...

    The 20th century was a pivotal time period for psychology. During this time period many sub-disciplines of psychology were created which in essence contributed to the growth and further development of psychology. One of those sub-disciplines of psychology that seems to constantly grow and has gained momentum over the years has been forensic psychology. Although Munsterberg was not the first to suggest that psychology should be applied to the law, instead it was Freud in 1906 during a speech to an Australian judge that there are factors within psychology that should be applied to the law. Although he was the man behind the discovery of forensic psychology and several other sub-disciplines of psychology.

    In order to understand how to compile evidence for criminal cases, we must understand the most effective types of evidence. This topic is interesting because there are ample amounts of cases where defendants have gotten off because of the lack of forensic evidence. If we believe forensic evidence is so important and it affects our decisions, then maybe we need to be educated on the reality of forensic evidence. If we can be educated, then we may have a more successful justice system. If we have a more successful justice system than the public could gain more confidence that justice will be served. In order to do this, we must find what type of evidence is most effective, this can be done by examining different types of evidence.

    Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.

    As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
