In this article, it goes over the famous OJ Simpson case and what went wrong throughout it. The evidence was never kept up very well and the chain of custody was broken a few times with some evidence. This allows it to not be able to be used in court. Even the body of Nicole Brown was contaminated throughout the investigation. With all of these problems brought many people to believe that some of the evidence was planted and that some of the people involved were lying. This connects to our unit about evidence and the importance of the chain of custody. Without a properly maintained chain of custody, lots of evidence that can be used in order to find someone either innocent or guilty cannot be used in the court of law. With this in mind, that is where the OJ case went wrong.
This article not only goes into how forensics fails and what evidence is wrong, but it goes into something more than that. This one takes a step further and explains how people can protect innocent people from the use of faulty forensics. It also explains what certain groups are doing in order to combat the wrongful use of faulty science in criminal cases. It explains how the two groups, NCFS and OSAC are looking at the causes of many errors that result in faulty science. This relates to our topic of DNA testing. It goes over how there are many ways that the tests can go wrong and how these wrongs can lead to innocent people getting in trouble for crimes they did not commit. This is just like how we went over false positives in DNA swabbing tests like potatoes and bleach.
An innocent man spent eight months in jail after being accused of murder following a police DNA test. This article explained how criminal justice can sometimes be too reliant on science. It gave an example of a man who had been put in prison for many months following a DNA sample that was positive in his case. The article went into detail on how forensic analysts sometimes ask the wrong questions in the case and assume things while searching for DNA evidence to put someone away. It also went into how many pieces of cases are never connected since the evidence is split up among multiple teams. This article related to our semester of forensics by going into detail how the teams look for and use evidence in cases. This mainly highlighted the downfall of these factors, but it still went into how there are multiple teams that do different jobs in order to help a case come to a close.
From fingerprints to bite marks, not all evidence is backed up by rigorous research. This article goes into seven common types of forensics and how they stand up in court. Of these seven, it mentioned DNA, fingerprints, bite marks, ballistics, arson evidence, drug testing and hair. It went into each specifically explaining how each can and cannot be used in court. It also showed how many forms of evidence cannot stand alone to prosecute someone in court. Scientific backup was missing in many types of the evidence mentioned. This relates to our year by mentioning all of the types of evidence. In each unit we went into different types of evidence and how they can and cannot be used in court. This article summarized seven of the main types of evidence that we covered throughout this semester. It leaves many questions though, as to which evidence is the best to use and also how these types of evidence do in fact hold up in court.
Forensic evidence is not nearly as accurate as we once thought. Throughout this video, it goes into many specifics on how certain types of evidence can go wrong throughout a case. It also explains how many types of evidence have no back-up in court, yet many people have been convicted of them; as seen in suspects found guilty through hair morphology. There are many types of evidence that may help a case, yet most of it does not solely have the ability to find a person guilty of a crime. This video hit on many of the types of evidence that we covered in class. It mentioned bite marks, hair morphology, ballistics, fingerprinting, and many more. It explained the shortcomings of each of these types of evidence. The video also went into specific cases that had either successfully or unsuccessfully committed people due to certain types of evidence.
This article began with a brief introduction explaining how a man, named Christopher Tapp, was pushed to confess to a murder that he stated later he did not commit. The jury decided he was innocent due to his confession eve tho there was lots of other evidence that proves other men being present during the crime. The article continues on and introduces the biologist, Greg Hampikian, and explains what he does in cases. It explained his background in forensics and it then went into detail of how DNA is used to help solve crimes with wrongfully committed suspects. Hampikian is shown in helping in multiple cases including Christopher Tapp's. The article ends with a hope for Tapp's release from prison in the near future. This article related to a few topics covered this year. The first being how DNA is used in crimes in order to help find the correct suspects. It explained, in some detail, that DNA can be used to help wrongfully committed suspects go free. The second way is how evidence holds up in court. Even though evidence was found at the scene that did not match Tapp, the jury still found him guilty since he confessed. This connects back to when we studied the CSI effect and types of evidenc in court.
