Is Forensic Science Reliable

The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination

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

Forensic science can be defined as the relationship between law and science; it answers the questions of how, why and who committed the crime, with the input of multiple actors. However, there are currently problems with

Many people continue to languish in jails all over the word while others have since faced capital punishment as a result of wrongful convictions. It is from this premise that innovation through DNA analysis has come to provide the much needed relief in correcting these errors. While there are many factors related to wrongful convictions, miscarriage of justice stands as the main culprit with many of these cases being faced with lack of conclusive or efficient investigations. There are several factors that come out as the main factors in contributing to miscarriage of justice such as false confessions, eyewitness misidentification, outdated evidence collection methods, snitches, incompetent lawyers and government misconduct among others.

In some cases, such as murder there are some people that have been wrongfully accused. Due to wrongful practices, people have been convicted of circumstantial evidence. ``DNA is a very powerful tool . . . but it is circumstantial evidence like other pieces of circumstantial evidence and a proper investigation still has to take place,'' she said. (Matthew, n.d.).

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

The definition of forensic science is any scientific research, method, or theory used to analyze evidence in an attempt to solve legal cases (Cho). In recent years, there has been growing public interest in forensic science, arguably because of the numerous television programs that glamorize its practices. This phenomenon is part of what is known as the CSI effect, or the process through which devoted fans of popular crime dramas develop unrealistic notions of forensic science methods, practices, and their applications in real life cases (Mancini 544; Stevens 37; Ley, Jankowski, and Brewer 52). The CSI effect has had more negative impacts on forensic science and society than positive impacts, especially in regards to what goes on in the

“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.

There have been many incidents where cases have needed a solid prosecution in order to convict the defendant in a murder or rape case. This is where DNA Testing comes in to help. By taking a DNA test, a person can be found guilty or not guilty. If a person claims they have been raped there can be a sperm sample taken from the suspect in order to prove that he is guilty or not. In addition, in a murder case there can be blood taken from the suspect so they can tell of his innocence. There are several ways to determine whether a person is guilty or not by this method. Many cases have begun to use this method saying that it is foolproof. People say this is the method of the future of crime

One of the most common issue forensic technicians deal with convicting of innocent people, and how jail time is a big part in that. Firstly, dealing with reasons for this issue would be DNA and how the DNA can be wrong on the victim and cause the case to be affected. In this article highly supports and says,“Testing and analysis of DNA is considered the most reliable of all of the forensic tools”(Lecher). DNA can also be a problem when a scientist is working on a victim as if a scientist messes up during their works causing an effect to that person's body and totally ruining the case because if your DNA being on them. Another reason for this would be innocent people are wrongly convicted of crimes. For this could happen in many ways known

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

A segment of the Forensic Science in the Criminal equity organization that the vast majority acquainted with these days, however, few individuals know how this particular science came to be. Overall, legal science is intended to utilize experimental standards to clarify obscure parts of a wrongdoing. Through the utilization of uncommon tests and lab gear that permits researchers to recognize decisively different parts of a bit of confirmation in an illegal behavior. On the off chance that you occupied with finding out about how this procedure came to fruition, you have to peruse the recorded data underneath. Here is a brief history

It is indisputable that the progression of forensics technology and knowledge has greatly improved the capability to catch criminals. Forensics of the past did not include the tools or knowledge that we now have. Forensics is not a perfect science nor has it ever been; however, we are closer to perfecting it than ever. Every criminal leaves behind some traces of evidence; it is up to the professionals to find and analyze it to solve cases. Looking at the timeline of forensic technology of the past to the present it is evident that it has evolved dramatically and will continue to do so.

Forensic science is a broad term that refers to the use of science or technology in a court room environment. Forensic science plays an important role in modern popular culture; the police procedural is highly dependent upon cutting-edge forensic science. Moreover, many people are aware of the impact of DNA testing on the modern criminal justice landscape. However, forensic science actually predates many modern scientific advances; almost as long as there have been controversies, there has been some type of forensic science.
