In order to understand how to compile evidence for criminal cases, we must understand the most effective types of evidence. This topic is interesting because there are ample amounts of cases where defendants have gotten off because of the lack of forensic evidence. If we believe forensic evidence is so important and it affects our decisions, then maybe we need to be educated on the reality of forensic evidence. If we can be educated, then we may have a more successful justice system. If we have a more successful justice system than the public could gain more confidence that justice will be served. In order to do this, we must find what type of evidence is most effective, this can be done by examining different types of evidence. One type of …show more content…
For this study forensic evidence can be considered DNA evidence and/or trace evidence of any kind, included to but not limited to tire tracks, bullet casings, glass shards, fingerprints, and hair samples. Although this study proposes the idea that forensic evidence is more important it currently is not used frequently in the justice system. A study found that out of the cases they examined forensic evidence was collected in 37% of cases but only 18% of those cases were examined (Peterson, Hickman, Strom, Johnson, 2013). Another study found that 38% of participants said forensic evidence was hard to come by while 62% said they had spent time on victim credibility (Menaker, Campbell, Wells, 2016). This shows us that forensic evidence is not used frequently, and more time is spent on making a victim credible instead of finding evidence. It is the purpose of this study to determine if forensic evidence is more important than circumstantial evidence and eye witness testimony. If this can be determined than less time can be spent on things like victim credibility for testimonies, and more time can be spent on analyzing forensic …show more content…
The CSI Effect is the idea that criminal shows and movies give viewers an inaccurate representation of forensic evidence and how it is used. If the CSI Effect is a confounding variable in this study, we can control for it by not letting the participants know the true meaning of the study until debriefing. It has also been found that not every crime drama talks about forensic evidence (Rhineberger-Dunn, Briggs, Rader, 2017). If not every crime drama talks about forensic evidence there is a chance that the drama the participants may watch does not talk about forensic evidence. If the participant watches a crime show that is about the FBI than they are less likely to have seen forensic evidence in that show (Rhineberger-Dunn, Briggs, Rader, 2017). This also helps control this confound. Though the CSI Effect and some of these studies are not directly related to the study being proposed, they do explore the various types of evidence that can be used in criminal cases. They also explore topics related to forensic evidence and their uses in popular social media outlets, because of this they are worth

- Forensic Science In The Real CSIexplanatory essayCrime is a common public issue for people living in the inner city, but is not limited to only urban or highly populated cities as it can undoubtedly happen in small community and rural areas as well. In The Real CSI, the documentary exemplified many way in which experts used forensic science as evidence in trial cases to argue and to prove whether a person is innocent or guilty. In this paper, I explained the difference in fingerprinting technology depicted between television shows and in reality, how DNA technology change the way forensics evidence is used in the court proceedings, and how forensic evidence can be misused in the United States adversarial legal system.

Many of forensic methods have implemented in research when looking for evidence, but the methods that are not scientific and have little or anything to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011). Defense experts are required to help the defense attorneys defend and breakdown all of the doubts in the prosecutors scientific findings in criminal cases. Scientific information is integral in a criminal prosecution, and a defense attorney needs to have an expert to assist he/she in discrediting the prosecution (Giannelli,

1206 wordsRead More - In the criminal justice system, the best chance of a fair trial and justice lies within cases that include physical evidence. Physical evidence, whether fibers, fingerprints, or DNA, can give a jury proof beyond a reasonable doubt. Physical evidence can convict a criminal, or it can free an innocent man. It can bring closure to families and to the law enforcement that work the cases. The following cases will show what physical evidence does in a criminal trial and the vast impact it can make. For each case I will examine how the physical evidence was important to the case and whether or not it could have made more of a difference if the presentation of the evidence were different. The five cases are: the Mosley case, the Warren case, the Chandler case, the Frediani case, and the Swift Case.

When crimes are done, criminals frequently leave behind evidence at the crime scene. Crime Investigators (AKA- CSIs) and Medical Examiners (MEs) the inspect the evidence left at the crime scene for leads to who did what. They try and rebuild the scene using the evidence and proof that they have. Forensic science has played a great role in finding evidence for crimes in history because it helps find the person who did wrong, the perpetrator, and it helps bring justice to the case. Forensics now are better than before because technological advances like DNA testing has been made, which takes forensics to a whole new level.

626 wordsRead More - Using Forensic Science to Identify Criminalsexplanatory essayRape, murder, theft, and other crimes almost always leave a devastating mark on the victim. More often than not, it would be impossible to identify the perpetrator a crime without forensic science and the technology it uses. Forensic science allows investigators to unmask the secrets of the crime scene. Evidence gathered at the crime scene helps to identify the guilty party, murder weapon, and even the identity of the victim (Harkawy, 1991: 276). The new technologies enables the forensic experts to have better and faster access to accumulated information, to be more accurate in the identification of victims or delinquents, and minimizes the possibility of wrongful accusations. New technology has improved the methods and techniques that forensic scientists and law enforcement investigators use, in order to provide a safer environment for other people. Information technology is one of the most important aspects in forensic science. It is very important for the forensic experts to receive the undisturbed evidence, such as fingerprints left at the crime scene, as quickly as possible, for more accurate readings. Thus using space technology, such as satellite communication, enables the forensic experts to "gather and digitize evidence at the crime scene, enter it into an on-site computer, and beam the data to a crime lab for swift analysis" (Paula, 1998: 12). Therefore, due to the use of this technology, forensic experts in laboratories can examine the evidence in short time, and the possibility of damage or unlawful manipulation of the evidence before the trial is minimal (Paula, 1998: 12). More often than not, "criminals" wear gloves at the time of the crime, thus to obtain a fingerprint...

When Forensic Experts are hired they may be called upon to give expert advice, give a third opinion on the evidence presented or serve as an expert witness. Regardless of whoever hires a forensic expert, the expert must be made available to make a testimony in court over their findings. This is due to the fact that in 2009 the U.S Supreme Court ruled that forensic scientists who test evidence must make a testimony in court. Nonetheless, whatever the purpose that the Forensic Expert is hired to serve they must go through a specific process which involves testing the evidence, but while doing so they must follow lab protocol. Once they have done so they must turn their findings into a r...

Evidence of a crime that detectives and law enforcement discover is as equally important as a good trial on part of the prosecution. If detectives aren’t able to find good solid evidence – that case usually isn’t bothered in being pursued. Several years ago, in the late 80’s, there was a murder case in Southeastern Oklahoma which now serves as a tragic example to the need for honest, constitutional work in the criminal justice system. Disreputable investigative procedures, fraudulent sources, and bad evidence were the foundation of this case that shattered innocent lives.

914 wordsRead More - Forensic Evidence Essayopinion essayForensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.
