The Role Of Eyewitness Testimonies On The Criminal Justice System

Eyewitness evidence has always been considering critical information when it comes to court trials and convictions. But how reliable are eyewitnesses? Scientific research has shown that eyewitness’s memories are often not accurate or reliable. Human memory is very malleable and is easily changed by suggestion. Relying on eyewitness evidence instead of scientific data often leads to wrongful convictions. Scientific evidence is much more reliable, and should be more important in court cases than eyewitness evidence.

According to “The Science Behind Eyewitness Identification Reform” there are two main variables that affect eyewitness testimonies “Estimator variables: are those that cannot be controlled by the criminal justice system. They include simple factors like the lighting when the crime took place or the distance from which the witness saw the perpetrator, and the degree of stress or trauma a witness experienced while seeing the perpetrator” and “System variables: are those that the criminal justice system can and should control. They include all of the ways that law enforcement agencies retrieve and record witness memory, such as lineups, photo arrays, and other identification procedures”. Eyewitness misidentification has led to 75% of false convictions that were overruled by modern DNA testing according to “The Innocence

Eyewitness testimony has long been viewed as important evidence in court cases. The general population believes eyewitness identification more than any other evidence, even if the witness account is conflicting with the other evidence presented. Studies show that eyewitness testimony is unreliable, and yet it is still considered the most important form of evidence. People think that if a person says they saw something then it must have happened. Currently there are no universal guidelines on how to obtain and present such evidence. The purpose of this paper is to explain why eyewitness testimony is unreliable, and discuss the proposed guidelines on how law enforcement agencies should gather identifications, as well how

An eyewitness testimony is unreliable because of many different things. Sometimes when witnesses see something they don’t see the whole crime, but only parts which could cause the wrong people to be in trouble. When it’s a serious crime the trial could take years and when asked to stand trial against the perpetrator the witness’s memory could not be fully correct anymore. You could forget important things or get mixed up with things you’ve seen somewhere else, like in a movie. Another reason they are unreliable is Because individuals with certain psychological disorders, like antisocial personality disorder and substance dependence, are at high risk for criminal involvement, they are also at high risk for false identifications by eyewitnesses.

There has been considerable interest and study in the accuracy or inaccuracy of the use of eyewitness testimonies in the current criminal justice system. Results collated by several studies add to the bulk of literature suggesting that the current usage of eyewitness testimony by the legal system is far from ideal. Currently, high emphasis is being placed on reviewing and reconsidering eyewitness accounts (Leinfelt, 2004). In particular, recent DNA exoneration cases have substantiated the warnings of eyewitness identification researchers by showing that mistaken eyewitness identification was the largest single factor contributing to the conviction of innocent people (Wells & Olson, 2003). In this essay, the use of eyewitness testimony in the criminal justice system will be explored, with a particular focus on the impreciseness of this practice.

In the past decade, eyewitness testimonies have cast a shadow on what is wrong with the justice system in today’s society. Before we had the advanced technology, we have today, eyewitness testimonies were solid cold-hard facts when it came to proving the defendant was guilty. However, time has changed and eyewitness testimonies have proven to be the leading causes of wrongful convictions due to misidentification. The Thompson and Cotton case is a perfect example of how eyewitness testimonies can put an innocent man behind bars.

In Canada, the leading cause of wrongful conviction is due to the factor of eyewitness account. It has been proven that individual’s minds are not like tape recorders because everyone cannot precisely and accurately remember the description of what another person or object looks like. The courts looks at eyewitness accounts as a great factor to nab perpetrators because they believe that the witness should know what they are taking about and seen what occurred on the crime scene. On the other hand, eyewitness accounts lead to a 70 percent chance of wrongful conviction, where witnesses would substantially change their description of a perpetrator.

As time goes on, eyewitness testimony has become more and more of a disputed topic due to many different factors. The first study I was exposed to was in an introductory psychology class which sparked my interest into the topic. For this reason, I chose to look at different demographics such as, gender and major, and see if those factors had any impact on the perception of eyewitness testimony. My main issues remained the same throughout this research project.

Eyewitness identifications is a noteworthy topic. Victims see their attackers from time to time, but

According to Scheck, Neufeld, and Dwyer (2003), the majority of convictions overturned by DNA evidence involved mistaken eyewitness testimony. The Innocence Project estimates that around 70% of the convictions due to eyewitness misidentification have been overturned by DNA evidence (2015). A main factor in this occurrence is that eyewitness memory is unreliable (Wright, 2007). Eyewitness identification in a line-up is an important tool in criminal investigations. The eyewitness evidence that results from these line-ups has an impact on the subsequent investigation and prosecution procedures (Wells, 1984). Furthermore, according to Wright, it is not just about witnesses making errors when identifying, misidentifying, or not identifying, a suspect

First, the human memory does not record all information like a video recorder. Mistaken eyewitness testimony is one of the major causes of wrong conviction. Events of crimes, will have so much stress or focus on a weapon, than the face of criminal (Wrongful Convictions , n.d.). The victim’s or eyewitness’s memory can be changed with an easy simple suggestion. Police procedure dealing with key witnesses by a “show up”. This is showing the suspect in a physical or a picture line up. The confidence of accuracy of identification and exhibited by the witness is a “crucial determinant of believability” by jurors (Furman, 2003). The best result of eyewitness testimony is taken identification immediately. The

The impact of eyewitness testimony upon the members of a jury has been the subject of various research projects and has guided the policies formed by the federal government regarding its competent use in criminal matters (Wells, Malpass, Lindsay, Fisher, Turtle, & Fulero, 2000). Therefore, eyewitness studies are important to understand how

A lawyer may use the research that shows eye witness’s memory for details of crimes contains significant errors when evaluating their testimonies to show that they may be confused or lying. Eye witnesses are unreliable because when they are held under pressure they tend to forget the important details. “When a criminal perpetrator displays a knife or gun, a witness pays less attention to other details of the crime making them less likely to recall what actually occurred.” (pg. 223) This means the lawyer could state that the eye witness was too distracted by the danger of their life rather than watching what actually happened. “One reason eyewitnesses are prone to memory-related errors is that the specific wording of question posed to them by

Eyewitness identification and testimony play a huge role in the criminal justice system today, but skepticism of eyewitnesses has been growing. Forensic evidence has been used to undermine the reliability of eyewitness testimony, and the leading cause of false convictions in the United States is due to misidentifications by eyewitnesses. The role of eyewitness testimony in producing false confessions and the factors that contribute to the unreliability of these eyewitness testimonies are sending innocent people to prison, and changes are being made in order to reform these faulty identification procedures.

Word count: 807 Eyewitness testimony is an account given by a person who was present at an event for example a robbery and they give a recollection of the event in front of the court of law. The testimony can include a description of the perpetrators, details of the crime scene and other factors which could help determine the defendant’s guilt or innocence. An eyewitness testimony is relevant in the criminal justice system because it’s one of the main forms of evidence used in court. Eyewitness testimony can be unreliable; an example of this could be discussion by witnesses which will be discussed later on the essay. There are measures that the Criminal Justice system (CJS) can put in place to increase the reliability of the testimony in turn
