What Are The Causes Of Dna Crimes

In McClure, Weisburd and Wilson (2008) summary article arguing that in addition to bench science, field experimentation involving forensic methods is key to assess the utility of various methods to solve crimes. The study reflected that there is a need for more research into many aspects of forensic science, criticizing the strength of scientific evidence that’s collected at a crime scene and interpretations of most forensic methods while omitting DNA testing. McClure et al’s (2008) explains that in sexual cases and homicides, the presence of DNA evidence actually increased the likelihood of prosecution and a conviction. According to the article “…the case of convictions, the odds-ratio for the presence of DNA evidence was 33.1 for sexual offenses and 23.1 for homicides” (McClure et al., 2008). Subsequently, the research shows that there was a consistent gradual decline in the national homicide rates that began in the 1900s and continued through into the 21st century. The decline of homicides in the US has dropped by from more than 90% in the 1960s to 62% in 2003. Even though this significant drop has occurred during the introduction of the new DNA testing

If a wrongful conviction occurs nowadays, our greatest chance to prove that it is a wrongful convictions is with DNA

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

Abstract: Over the past twenty years, advancement in DNA technology has directly led to the exoneration of nearly 300 people in the United States. In addition to these scientific advancements, a growing body of literature has focused on the significant roles eyewitness misidentification, so-called “jailhouse snitches,” and false confessions have played in contributing to wrongful convictions in U.S. courts. The aim of this paper is to examine the occurrence of wrongful conviction in criminal trials and the effect of DNA testing on bringing attention to the alarming frequency of these unjust judicial outcomes. Through an examination of previous wrongful conviction research and appellate court rulings, this paper will also explore the extent to which permitting wrongful convictions to be upheld constitutes a violation of civil liberties. Finally, this paper will discuss an important contradiction that advancements in science have exposed within our criminal justice system; while DNA technology and other advanced forensic techniques are increasingly being relied upon to secure criminal convictions, the justice system seems to be correspondingly reluctant to consider these forms of evidence for the

Every time an innocent person is exonerated based on DNA testing, law enforcement agencies look at what caused the wrongful convictions. There are many issues that contribute to putting guiltless lives behind bars including: eyewitness misidentification, false confessions, imperfect forensic science, and more (Gould and Leo 18). When a witness is taken into a police station to identify a suspect, it is easy for their memories to be blurred and their judgment influenced. This can lead the witness to identify a suspect who is actually innocent. Flawed forensic science practice also contributes to wrongful imprisonments. In the past, analysts have been inaccurate due to carelessness, testified in court presenting evidence that was not based

Maryland. Raynor was convicted of rape after the police swabbed his skin cells from an armrest of a chair. Originally he agreed to take part in the police investigation but he refused to supply his genetic information. So, when the police considered his DNA evidence, he argued that his Fourth Amendment rights were violated. However, the court, with a 4-3 decision, decided that this collection was constitutional and the police can collect any DNA evidence as they come across them. Unfortunately, this case was denied of review by the U.S. Supreme Court. Meanwhile, DNA collection laws exist in over half of the states and vary greatly on when DNA samples can be taken and when the samples can be

The first DNA-based conviction in the United States occurred shortly after in 1987 when the Circuit Court in Orange County, Florida, convicted Tommy Lee Andrews of rape after DNA tests matched his DNA from a blood sample with that of semen traces found in a rape victim (Calandro, 2005). It was two years later that DNA was again ruled admissible in a Virginia state ruling. In the years that followed the use of DNA in trial proceeding was not disputed. It was not until the technique of obtaining the evidence was more largely used did the practice become questionable.

“In 1984, a British geneticist named Alec Jeffreys stumbled upon one of our most important forensic tools: DNA fingerprinting. Since his “eureka moment,” the scientific technique has been used successfully to identify perpetrators of a crime, clarify paternity and exonerate people wrongly convicted” (Jones). DNA evidence, specifically simple-mixture, is the most accurate type of forensic evidence we currently have at our disposal, but even it is not infallible. Other types of forensic evidence are much less accurate, but unfortunately their use is still permitted in U.S courtrooms. Jurors may be misled by experts within the courtroom as well. These misconceptions about the accuracy of forensic science and the field in general lead to many problems in the courtroom.

In order to properly discuss this topic, the paper has been separated into three main parts which include: DNA evidence, death row, and the Innocence Project. The section regarding DNA evidence starts out with what exactly is DNA and why it is so important to science, forensic science, and then gets further into detail of how it became completely admissible in court cases. The second section being discussed is the death penalty in the United States and has one subsection. It begins with basic information on the death penalty and statistics of conviction, wrongful and not, and what causes people to be wrongfully convicted. The subsection for the death penalty section discusses just a few wrongful conviction cases; what went wrong that these people were wrongly convicted and did they ever get a chance to plead for their innocence after being sent away to death row. The third and final portion discusses the newer and very important program called the Innocence project, explaining what it is they do and how it has helped people.

Lawton, I would like to first say that I enjoyed reading your forum. The incident that occurred to Ayers was unfortunate. However, there are many cases that occur just like his. The Innocence Project was established to help those individuals who were falsely accused. According to Mangan (2004), “The program is an offshoot of the Innocence Project, a national nonprofit legal clinic that handles many cases in which DNA testing of evidence can conclusively prove the innocence of some prisoners” (p. 26). However, it takes more programs to help those such as Ayers who have been falsely accused. In his case, he was proved incident. However, many individuals do not have that happen and are locked up for years, if not executed. The investigators and

The scary truth about the criminal justice system is it does have errors. For every seven executions, one death row prisoner is found innocent. Before DNA testing, they could not match a blood sample to just one person, only a blood type. In the late 1990’s DNA testing revolutionized the accuracy of verdicts. Every person, besides identical twins, has their own unique DNA sequence. They can match hair, skin tissue, blood or any genetic material to one individual. (“DNA Testing and Capital Punishment”). Now that this new technology is released, many inmates who were convicted before this technology was introduced want the opportunity to be exonerated. Along with DNA testing, there has been a push to set general guidelines for the attorneys appointed

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)

Forensic science is defined as the practice of utilizing scientific methodologies to clarify judicial inquiries. The field of forensic science contains a broad range of disciplines and has become a vital aspect of criminal investigations. Some forensic disciplines are laboratory-based; while others are based on an analyst’s interpretation of observable patterns (Kourtsounis, 2009). According to the Innocence project’s website; in greater than fifty percent of wrongful convictions, the use of invalidated or improper forensic techniques played a role in cases; which were later
