Assess The Difference Between Simultaneous And Sequential Line-Up

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.

The participants seated themselves around a table, these confederates were not known to each other, and most important concept of this experiment relied on the fact all of the participants were working together, but for one. They took turns in a fixed order to call out publicly which of three comparison lines was the same length as a standard line on the left card. In reality only one person was a naive participant who answered second to last, the rest were experimental confederates instructed to give erroneous responses.

While the cognitive interview does prove to be effective in increasing the amount of accurate information elicited from witnesses of crimes, it does not necessarily increase the credibility of eyewitness testimony by reducing memory error and confabulations. The cognitive interview has been shown to elicit more information than the standard interview, but the two types do not differ on incorrect information or confabulations

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.

Eyewitness misidentification can pose a serious threat in forensic evidence. Eye witness testimony can easily be tampered with due to words or phrases used. Bias is a major issue in identification especially if the police officer uses suggestive tones to portray whom they believe is the suspect. Some witnesses will change their opinion when they hear new information of the suspect. A study has shown that words can play a major impact in the witness' mind and cause them to recall false information. False information can also stem from human memory, age, distance, and how long it took before a witness could recall the information. It has been shown that due to the confidence that a witness may have, it could impact the court systems' reliability on the witness; however, there are several solutions that can be done to prevent misidentification in the court of law. Some examples that can be done are blind administration, lineup composition, instructions, confidence statements, and

Eyewitness identification are considered to be the most powerful evidence against a suspect. There are numerous reasons for this to occur which includes stress, human memory, and the focus on weapons which leads for the eyewitness to focus less on the perpetrator. When an individual is in a position with high stress, their ability of remembering what actually occurred won't be easy to prove. It leaves the eyewitness unable to recall what occurred at the tie of the scene. This has been a huge problem over the years. According to “Carla Stenzel” eyewitness misidentification will occur because our memory is dynamic. It is very impossible for our brains to perform everything we see. Our memories take in pieces of information and processes the most important information. When a witness is asked by a police officer to give certain details of a suspect, they won't be able to remember how exactly they looked like but will be able to give out certain details like their height, race, and hair color. When a crime is being committed witnesses usually testify that there focus was more on the perpetrator's weapon. All they can focus on would be the size and shape of the weapon and focus less on the actual suspect. Another contribution would be the way the investigator presents the operator to the witness. The investigator prepares a lineup which includes a six pack of people. The use of a six pack lineup has

According to the Innocence Project, the misidentification of eyewitness is the most common causes of wrongful conviction in which approximately 75% of the cases has been overturned because of this case. There are several causes of eyewitness misidentification, which includes the types of lineup, post-identification feedback effect, and does the instructions given. The lineup is a process which the suspect is identified by the witness as the perpetrator. The main reason that the

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

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

There are many different factors that play a part in the increased chance of a witness correctly identifying a suspect. Such factors should be brought to the attention of the jury and the judge to help in properly assessing whether a witness is correctly identifying a suspect. A study by Magnussen, Melinder, Stridbeck, & Raja (2010) found that of the three different types of people: judge, jury, and general public, that for the most part all where fairly ill-informed on the reliability of eyewitness testimony with judges having the most. Judges only had about an 8% difference in knowledge when compared to jurors. With this information it is very clear that education on the reliability of eyewitness testimony needs to become more of a general knowledge information for the everyone, especially people who are involved in upholding the law. Another factor to look into when evaluating the accuracy eyewitness testimony is the role that memory plays. Memory is divided into three processes: perceiving, remembering, and recalling information (Simmonsen, 2013). There is plenty of room in all three of those stages to forget or falsely remember something. Some factors that play a part when a person perceives an event is the amount of time they are exposed to the event and the suspect. A study conducted by Horry, Halford, Brewer, Milne, & Bull. (2014) found that witnesses were increasingly more likely to correctly identify a suspect if they had been exposed to the suspect for sixty

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.

Two hypotheses were presented in this article. Both of them focus on how unfair lineups are more likely to cause witnesses to make false accusations about who actually committed the crime. Does the lineup cause subjects to
