Dna Testing And The Criminal Justice

Well, in nearly 25 years since post-conviction DNA evidence has been used to demonstrate criminal innocence, even in cases that landed defendants on death row or in prison for life. Eyewitness misidentification, forensic science errors, false confessions, government misconduct and bad lawyering are many of the reasons wrongful convictions occur. Eyewitness being the most common. Sometimes it can be done by error and other times it is actually done intentionally. In seventy-seven percent of the DNA exonerations, eyewitness misidentification led to wrongful convictions (The Innocence Project- How wrongful conviction happen).

DNA exonerations are very common. So much so that in the United States alone, there have been “317 post-conviction DNA exonerations” (2014). The very first DNA exoneration dated back to 1989. The Innocence Project examined these DNA exonerations and found that “8 of the 317 people exonerated through DNA served time on death row. Another 16 were charged with capital crimes but not sentenced to death” (2014). More so, the average time served was about 13.5 years, and the average age was 27 (2014). This means that before the age of

In addition to undeserved charges, DNA testing has exonerated hundreds of people for crimes in which they were convicted over the past few years. When DNA testing became readily available to the criminal justice system, crucial flaws began to surface. It was realized that people were serving hard-time for felony crimes they didn’t commit.

investigations both past and present. It can be used to identify criminals when there is evidence

DNA’s certainty is dramatized in today’s society, which gives lay people the impression that DNA is infallible; however, in the case of Wayne Butler and others, the fallibility of DNA is exposed. Wayne Butler was accused of sadistically murdering Natasha Douty who was found beaten to death on Brampton Island in 1983. Wayne Butler was vacationing on Brampton Island during the timeframe of the murder; however, claimed to be jogging during this time. After submitting a blood test, Butler was eliminated as a suspect. However, Butler was arrested in 2001 for this murder because semen, which was found on the towel at the crime scene, was found to be a match. The John Tonge Centre performed a DNA test on the evidence on the towel. Butler was found innocent after it was identified that the John Tonge Centre mislabeled the test tubes containing the crime scene evidence. (“DNA Evidence”) This case proves that DNA testing may not be as reliable as we think.

With the number of DNA exonerations growing in the recent years, wrongful convictions reveal disturbing trends and fissures in the justice system. It shows how broken the system is, and why it needs urgent fixing. According to Huff (1996), over ten thousand people are convicted wrongfully for serious crimes each year. This study established that factors leading to wrongful convictions are false eyewitnesses, a prejudiced jury, incompetent prosecutors, and suspects’ ignorance. Where DNA evidence clears a suspect, array of reasons emerge; misconduct, mistakes, to race and class factors. It is important to make DNA data available to attorneys in order to enable them mount a strong

DNA is considered an individuals genetic fingerprint, thus it is exclusive to each and every individual. Since this exclusivity exists, DNA is a tool used for identification purposes. It has been utilized for investigations of serious crimes, identification of individuals killed in mass disasters, wars and paternity uncertainties1. Since the inception of the use of DNA in the 1980’s thousands of criminals have been caught and prosecuted with the help of DNA evidence2. Additionally, countless victims of mass disasters have been identified through DNA and returned to their loved ones. Although, there are various benefits to employing DNA it does not come without a sundry of ethical and legal concerns. The ethical concerns that have presented themselves are questions involving scientific reliability, DNA evidence in court, human rights, and finally the other uses of the DNA database.

With the initiative of the innocence project, many of these convictions are being overturned, allowing families to be reunited. There are many reasons why these wrongful convictions happen. The most common among them is false eyewitness identification, which has played a role in more than 75 percent of wrongful convictions overturned by the Innocence Project initiative. Once presumed to be incontrovertible, the ever growing body of evidence now tells that eyewitness identifications are unreliable (please see image A2 for the trending of exonerations year by year). In approximately, 25 percent of DNA exoneration cases, innocent people were coerced into making false confessions. Of the 292 people freed by the Innocence Project, 28 actually pled

DNA evidence is extremely helpful in criminal trials not only because it can determine the guilt of a suspect, but also because it can keep innocent people from going to jail. The suspect must leave a sample of their DNA at the crime scene in order for testing to occur, but DNA can be found in the form of many things such as semen, blood, hair, saliva, or skin scrapings. According to Newsweek, "thousands of people have been convicted by DNA's nearly miraculous ability to search out suspects across space and time… hundreds of innocent people have also been freed, often after years behind bars, sometimes just short of the death chamber" (Adler ). Though some may think it is a waste of time to go

The Innocence Project was established in the wake of a landmark study by the United States Department of Justice and the United States Senate with help from the Benjamin N. Cardozo School of Law (Schneider, 2013). This study found that there were numerous reasons why people are wrongfully convicted including, but not limited to eye witness identification, perjured testimony, improper forensic science techniques, and government misconduct (Roberts & Weathered, 2009) The original Innocence Project was founded twenty two (22) years ago as a part of the Cardoza School of Law of Yeshiva University in New York City, New York (Davis, 2012). The Innocence Projects primary goal is to exonerate those whom have been convicted of a crime when there is DNA evidence available to be tested or re-tested (Mitchell, 2011). DNA testing has been possible in five (5) percent to ten (10) percent of cases since 1992 (Risinger, 2007). On the other side, other members of the Innocence Project help to exonerate those have been convicted of a crime where there is no DNA evidence to test. A goal of the Innocence Project is to conduct research on the reasons for wrongful convictions, how to fix the criminal justice system, as well as advocate for those who have been wrongfully convicted (Steiker & Steiker, 2005). The members of this organization strive to teach the world about the dangers of wrongful convictions. To date, this non-profit legal organization, has freed three hundred eighteen (318)

In the science text “DNA analysis: The key to solving crimes” by Richard Platt describes the key to solving crimes with DNA. DNA can be extracted from every cell in the body and evidence can help prove someone’s innocence.

The use of the DNA testing has been problematic in many ways. There is a chance of errors and mistakes in the DNA testing as well. These tests may also be infallible. These tests may also produce the wrong results. So, In this case, this is against the individual rights as the person who wants the exact result of the DNA testing will be subjected to lie. So, this is like hurting the rights of the people. Furthermore, the risks of attaining a match in the DNA test is also high that can also be misleading at times. This has been proved by many Councils and research. So, the innocent people are misleading in these cases. The false results occur when there is a cross contamination of the samples. In many cases, laboratories also mistype the results.

There are often mistakes made that falsely determine an individual’s sentence. Sloppy police work and loss of documents are examples of careless errors. There is also some room for error with determining the results of a DNA sample that do not fall under the human error category. Many times there may not be ample DNA samples at a crime scene. Only a fraction of crimes reveal DNA. Drive-by shootings and bombings often do not provide DNA for investigation purposes. “There is a public perception that DNA is the cure-all for these kinds of mistakes. DNA is not the whole answer.” (Dieter, Richard) Eye witnesses cannot solely and accurately determine a person’s fate 100 percent of the time. There are numerous amounts of cases in which those found guilty were indeed later found innocent. Many times, these individuals have already served time in jail. Many argue that the time inmates spend in

Over the course of time, numerous techniques in DNA analysis have resulted in wrongly accused individuals in court cases. It is significantly important that the techniques used are highly accurate in order to prevent these accusations in the legal system. In addition, there is always the fear that evidence may be contaminated by time it is reached, this is another reason why it is important to have time efficient, accurate techniques. In the past, restriction fragment length polymorphism (RFLP) has been used in the testing of DNA. The process required a small amount of cells either gathered from strands of hair or dried bones and teeth. Today the most common form of DNA analysis is polymerase chain reaction (PCR).
