Eyewitness Speech Outline

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, for the most part, is considered reliable eyewitness identification by the courts as excellent evidence to proof crimes at trial. Yet, Bennett Barbour’s arrest revealed these inaccuracies as he was wrongly arrested due to an over-reliance on eyewitness identification. Barbour’s physique, specifically his

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

On the other hand, there are many situations where criminals go free because eyewitnesses were unable to identify them. With Dr. Brewer he had a different idea knowing that strong memory traces are easier to access than weak and mistaken ones, which is why he only gives his witnesses two seconds to make up their minds. Once they make up their mind he also asks them to estimate how confident they are about the suspects they identified, rather than insisting on a simple yes or no answer. With this version of the lineup he had a large boost in accuracy and the eyewitness performance ranged from 21%-66%. Dr. brewer learned that when it comes to the human mind that more discussion is often dangerous. Instead of simply evaluating our familiarity with a suspect’s face, we begin searching for clues and guidance. Sometimes this involves picking the person who looks the most suspicious, even if we’ve never seen him before, or being persuaded by the indirect hints of police officers and lawyers. As a result, we talk ourselves into having a memory that doesn’t actually exist. (Jonah Lehrer

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 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.

A defendant’s guilt is often determined in a single moment of fleeting emotion. A pointed finger, accompanied by the solidifying eyewitness statement “He’s the one!” is enough for a jury to make its final decision in a court case. Although it is understandable, when faced opposite of the individual creating the accusation, to place one’s belief in the accusation made, the credibility of the eyewitness’s account of events are rarely taken into consideration. Psychologists have taken part in research that recognizes the unreliable nature of eyewitness statements used to determine guilt because of the instability of long term memory acquisition and because of this, eyewitness accounts of situations should not be used before a jury in court.

However eyewitness misidentification leads to more wrongful convictions than any other evidence being that it plays a role in 70 percent of cases overturned through DNA testing (Grimsley, 2013). There are multiple factors as to why eyewitness identification is often inaccurate, one reason being that it relies heavily on memory which involves three processes: encoding, storage and retrieval, all of which are susceptible to errors (Costanzo and Krauss, 2014). There are other factors that can affect one's memory such as unconscious transference (e.g. when you unintentionally replace someone's face with what one you may have seen on television, etc.), suggestive or leading comments (i.e. administrators providing cues to eyewitness about which person to pick at a lineup), cross-race effect (cross-race bias) (i.e. we often misidentify others of a different race than our own race), and so forth (Costanzo and Krauss, 2014). Despite that eyewitness identification is often inaccurate, it is still commonly used within the criminal justice system. This has affected mostly Africans-Americans negatively being that they most often fall victim to eyewitness misidentification. This is shown in a study done by Scheck, Neufeld, and Dwyer (2000) where they studied eyewitness

Information is the lifeblood of a criminal investigation. The ability of investigators to obtain useful and accurate information from eyewitnesses of crimes is crucial to effective law enforcement, yet full and accurate recall is difficult to achieve (Stewart, 1985). Such elicitation of complete and accurate recall from people is important in many aspects of life; specifically, eyewitness recall may determine whether a case is solved. Principle advocates of the cognitive interview (Fisher, Geiselman, Holland & MacKinnon,

All of the above factors and causes for wrongful causes of eyewitness testimonies as well as factors such as: the lighting of the area where the incident happened, how long the victim was with the victimiser, how stressful the situation was and the amount of time between the crime and alerting authorities can have a huge impact on ones eyewitness testimony. Although the witness may seem adamant and confident in their testimony, the above factors should be assessed and taken into consideration when reflecting on the accuracy and reliability of the witness’s testimony.

“Wrongful convictions happen every week in every state in this country. And they happen for all the same reasons. Sloppy police work. Eyewitness identification is the most- is the worst type almost. Because it is wrong about half the time. Think about that.” (Grisham). Wrongful convictions can happen to anyone, at anytime. Grisham implies wrongful convictions happen for the same reasons, careless police work as well as eyewitness identification. An eyewitness identification is a crucial aspect in detective work because it essentially locates the person at the crime scene. This is the worst cause of wrongful convictions because it is wrong half the time.

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.

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

The results of the studied showed that stress induced SP participants recalled fewer items on test 2 than non-stressed SP participants, whereas there was not a difference in the RP group. Memory impairment caused by stress only resulted in the SP group. In addition, the stressed RP participants showed the performed equally to the non-stressed RP implying that stress has no affect on memory when retrieval practice is used to learn material. The researchers also found that stress had no immediate effect on memory for either group of

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.
