DNA Evidence In Criminal Justice

The technology advancements alone have led to several cold cases freeing the wrongfully convicted. What are some of the contributing factors wrongful convictions? There is no way to make a right for the justice system can do for those wrongfully convicted. The loss of time however, there have been some initiatives about compensation for the errors that have happen. The public opinion is so strong when it comes to catching these criminals.

Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime. 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.

The main special case to this is identical twins. Scientific researchers in forensic cases can use DNA profiles to recognize criminals. A DNA profile is similar to a genetic unique fingerprint. Get data sheet: DNA profiling The outcomes from DNA profiles may be used as a part of court. like if the samples gathered from a crime scene may give a positive results with the DNA of a suspect.

Furthermore, everything should have been labeled and placed on an evidence log to ensure that it was the DNA from the actual crime scene. Although, it could have been Mr. Simpson DNA if the proper protocol had been followed they may have been able to get a guilty verdict on the double murder as well as a life sentence. I feel that given all of the fact and evidence in the case that the court did make the right decision. Unfortunately, if the evidence has been contaminated it cannot be used in court and that makes a big difference in a case. Therefore, this case showed the nation that if the evidence does not fit the crime than there is no possible way to find someone guilty of a crime because there is no physical evidence to prove that they actually committed the

Entrapment is used by officers to persuade and lure suspicious civilians to commit a crime that they have not been proven guilty of. This article talks about entrapment and explains positives and negatives of they system. The article focuses on the holes and unclear frame work in the entrapment tactic. Entrapment is a useful tactic in catching suspicious criminals before they commit a crime that could possible hurt someone. This is a good and efficient tactic for officers, it keeps the innocent safe.

Thus, preserving crime scene evidence is often one of the first ‘fast- track’ action which the police would normally perform straight after the crime unless, there is an injured victim, as then that would be a much critical task for the police, as preserving life means securing important eyewitnesses. In good practice, the police usually access and collect as much information as possible right after the incident, which is also referred to the ‘golden hour’. This is to ensure that valuable evidence is collected with minimum chances of being tampered or destroyed (Stelfox, 2012: 152), in particularly forensic samples, which are prone to contamination when the crime scene is at outdoor (UNODC, 2009:

The case indicates that some bodies had undergone decomposition leaving skeletons while another was partially decomposed. It is not possible to prove the identity of the victims without the use of forensic biology, and in particular DNA matching. Matching DNA profiles of the crime victims with DNA profiles of people who have lost their loved ones under mysterious circumstances will help in establishing or excluding paternal relationship, and thus the identity of the victims (Kayser, 2017). It is highly possible that the crime scene contains DNA samples of the person who committed the

While it is true innocent people have been exonerated while on death row and some may have even been executed, new technology provides greater evidence to proof either one’s guilty or innocent ( “Wrongful Convictions Overturned in Death Penalty Cases Due to Advances in DNA Testing”). The advancement in DNA testing allows future cases and past cases to obtain justice, ensuring that the innocent will not have to worry of wrongful convictions and victims families can gain closure. There are other factors that can tie into wrongful convictions these are the jurys, courts, and police. Bias based on race or religion does occur, prosecutors have been found to sometimes target individuals using the death penalty as a trophy to show off (“Wrongfully Convicted Louisiana Man Asks Justice Department to Investigate New Orleans Prosecutors”). In 2010 exonerations for black males were 71, higher than white males which were 53 (“Capital Punishment: Cruel and Unusual?”).

Initiatives against human trafficking are proving effective because trained citizens know how to identify a trafficker or victim and traffickers can’t hide from the law as easily. The first reason that initiatives against

intro Cognitive psychology is one of the very important areas in psychology. It is concerned with mental processes, such as how people think, learn, perceive and remember. In certain situations, an individual’s memory can seal someone’s faith. If a person has been present to a crime, their perception and their memory are seen as crucial to identifying the person who has committed the crime. Before DNA analysis found its way into courtrooms in 1986, eyewitness testimony was seen as the most persuasive form of evidence.

In a study, 77.2% of profiling reports provided by the FBI was indeed considered useful in providing an outside perspective on a case and in helping to focus on the investigation. Criminal profiling may be misused by several law enforcement officials but you can not deny that has been a legitimate investigation tool for many years. With the progression of criminal profiling there is going to be misuse and misconceptions however, you can’t discredit the beneficial analysis that profiling brings. It’s efficiency in providing insight to the investigators showcased how a setback like racial misuse won’t interfere with getting the crime solved at the end of the

Stories about the use of DNA evidence to convict offenders or exonerate defendants in criminal cases have become increasingly common in the recent years. Forensic DNA technology is transforming the way law enforcement officers investigate crimes, especially violent ones. DNA has an extremely important role in criminal trials due to its power of exoneration of innocent individuals. Many wrongfully convicted individuals, but later exonerated by DNA evidence, falsely confessed or made an incriminating statement. This can be seen in the Earl Washington case as presented by Frontline.

It is also important for the media to note that crime is everywhere and it is unfair to view Anonymous Community as one fool of criminals. By taking the time to analyze the community, the media will realize that the members of the community are not ignorant of crimes since they also fall victims to the

Others may claim that DNA evidence isn’t sufficient to convict someone for a crime or prove others innocent. But, DNA evidence from crime scenes has helped solve many more cases and found the criminals than those cases where people were wrongly convicted. Penal code 1405 gives convicted felons the chance to submit a written motion to the court to request forensic DNA testing. Penal code 1405 should remain a law because it gives incarcerated
