Introduction

The study of law and the judgment in the criminal case, especially with respect to the DNA evidence in the United States, the United Kingdom and Australia also other countries, the study guides in terms of the pros and cons of the DNA evidence in proving the criminal justice system. Consequently, the using the DNA evidence will benefit greatly with the Thai and Portuguese Criminal Justice.
In the process before trial, the step of seeking, collecting DNA evidence and the act listening to the statements and weighting the DNA evidence has to be carried before a Thai court can make any considerations. This is true not only in the terms of laws but also in the usage of discretion when deciding which evidence should be employed. The current trend in Thailand, scientific evidence which surrounds an incident is the most important in terms of weight and credibility of DNA evidence.
However, several murder cases have different issues, the issue of the facts and issue of the law which needs to be set up to the standard. Now the judge 's discretion has difficulty summarizing the rules. Therefore, it is necessary to find a way for the corrective practice. In order to compare the laws and duties of legal officers, this study will examine whether Portugal has the same problems as in Thailand. If not, what solution does Portugal use to tackle this …show more content…

Because of the growth of the population, world social have committed many crime offences as well. The law needs to control the social order and bring peace to human society. Commonly, science has helped to solve the legal problems in communities. As Simon A. Cole and Michael Lynch stated that “Forensics is the “silent witness,” it “never lies,” and it cannot misremember or be biased or bribed.” “Forensic science is often seen as an applied science used in criminal investigations and criminal trials.” Not only, a minor crime but also serious crimes, the DNA technology can help to identify criminal problems of the United States and the world such as transnational crime, terrorism , and illegal migration.
In Thailand, the DNA technology has shown a major role in important events in the country. On25 December 2004, the tsunami occurred in Phuket and Phang Nga province, where is a favourite tourist attraction in Thailand.This tragedy led to loss of many people and foreign tourists who came to relax during Christmas holidays. At that time, DNA evidence led to the identification of missing people and dead people but at that time there was no DNA collecting record like DNA Database in

Alan Crotzer—DNA Exoneration In the United States, there have been a total of 321 DNA exonerations to date, with twenty of these exonerees having served time on death row (“The Innocence Project,” n.d.). Alan Crotzer was not one of these twenty, however he was sentenced to 130 years in prison for a crime that he didn’t commit. Charged and convicted of sexual battery, kidnapping, burglary, aggravated assault, robbery, and attempted robbery, it wasn’t until 24.5 years later, on January 23, 2006, that Crotzer was released from prison after post-conviction DNA testing proved his innocence (“The Innocence Project,” n.d.).

It is hard to believe that over seventy percent of convictions overturned through DNA testing were based on false eye witness testimonies. Due to conflict and hesitation in eye witness’s long term memory, testimonies from them are frequently inaccurate and give distorted information on the crime. The demanding process of encoding, storing, and later retrieving memory all takes place during a rather rapid and stressful period of events, making the procedure all the more tedious for the witness. For this reason, eye witness testimonies are now seen as unreliable for giving flawed results and have been slowly replaced with more modern means of finding evidence such as DNA testing.

We know that DNA testing is giving hope to the hopeless in prison. Margret Berger (2006) comments, “Even though the number of inmates released as a consequence of DNA testing is minuscule in contrast to the two million persons incarcerated in the United States, the DNA exonerations have had an enormous impact on the fundamental assumptions about the American criminal justice system and how it operates.” Changes like the desirability of the death penalty, the growing concerns on how forensic laboratories operate alongside the increasing interest in forensic science overall. For instance, as the number of exonerations continues to rise, the number of people being placed on death row is decreasing thanks to Supreme Court rulings that juveniles under the age of 18 and the mentally ill cannot be sentenced to death. The death penalty is overall losing its appeal to society, not just because of the DNA testing, but people become aware of the wrongful convictions of other crimes as well.

Although, in our lab report, suspect ones DNA matched the crime scene when cut with enzyme one, this can be explained by how closely related the two suspects are. Therefore two enzymes were used to cut the DNA; the suspect has to match both. Moreover, the limitation to DNA fingerprinting is, if a person were to have an identical twin. This is because identical twins have the same DNA because they come from the same egg. If a suspect’s DNA matched that of the one being tested, and they had an identical twin, a farther investigation would need to be done.

For example, on account of R. v. Jama (Victoria, 2008), the suspect, Jama, was wrongfully sentenced assault in light of flawed DNA prove. Following Jama 's full absolution, Milanda Defeat of "The Australian" (third October 2009), considered this adventure as an, "unfortunate premature delivery of equity". Moreover, as per Adam Bennet of SMH, second October 2009, DNA prove is imperfect, "since it experiences a few hands and a few phases". Accordingly, even though the application of technology in the criminal examination process has aided the explaining of numerous cases, it has its issues. The criminal examination process neglected to keep an unsuccessful labor of equity, and thus, for the suspect, who was denied of his entitlement to freedom, the casualty, who neglected to see equity on her part and society, who imprisoned a pure man, it must be considered that the criminal examination process has neglected to accomplish equity for the privileges of casualties and suspects, mirroring its

DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
