The Pros And Cons Of DNA Testing

493 Words2 Pages

Many people every year are charged with crimes they didn’t commit, whether they pleaded guilty or eye-witnesses claimed and testified in court that the defendant committed the crime. Before DNA testing in 1989, there was an error rate of 6% and now that rate has dropped tremendously because we focus less on the stories witnesses claim to be true and focus more on hard evidence. Between 1989 and 2003, there was estimated to be 340 people wrongly convicted and over the years investigators found that 4,000 people were convicted for crimes they did not commit. Even today with all the technology and resources we have to determine who committed the crime based on physical evidence, we still have many wrongful convictions still happening to this day. …show more content…

We’ve revamped our ways of tapeing these sessions, we’ve moved from tape recorders to cameras with audio files in order to capture as much evidence and details from the victims stories as possible. Even with taped interrogations and perjury laws there’s no way to force the truth out of a witness, especially if they have evil intentions. The closest we can get to the truth is through polygraphs, which can still be refused by the suspect because lie detector tests are not mandatory. People have been charged with crimes they didn't commit for a long time now. People may tell a false story, or lie under oath to favor one defendant over another. Perjury, lying under oath, has been an issue for along time. Perjury can lead to the wrong victim accused guilty for a crime they did not commit nor participate in. We can not do anything to fix the issue of lying because you can not force the truth out of someone, however, we have tried by inventing polygraphs and those don't always

Causes Of Wrongful Convictions In Australia

119 Words | 1 Pages

Wrongful convictions are a problem that most government officials won’t admit. The United States and other countries such as Australia have been susceptible to these miscarriages of justice. This can arise from a snowball effect of scenarios such as witness misidentification, perjured testimonies, coercive methods of interrogation, prosecutorial misconduct and ineffective counsel. These are some of the reasons that can potentially lead innocent people to be convicted of crimes they did not commit. The thousands of exonerations in the United States has caused concern for other nations to reevaluate their criminal justice system.

False Confessions: The Central Park Jogger Case

1374 Words | 6 Pages

While they all may not use deception, there are a decent amount who do. These individuals would need to adjust their strategies and ways to get a confession from a guilty suspect. This proposal does seem to be for the best of all the members of the community for a multitude of reasons. The first and ultimately main reason is because the ‘giant, looming cloud’ so to speak, is erased from the concept of interrogations.

False Confessions Case Study

1426 Words | 6 Pages

Research by Larmour, Bergstrom, Gillen, and Forth (2014) claims, “In twenty-two percent of trials with a false confession present, individuals were sentenced to death” (94). This number is not a joke, twenty-two percent of cases with false confessions actually had people that were put to death before they could be found innocent. Many cases call for reforms, but many of them are too little too late. According to Alan Hirsh (2014), “Juries may convict the false confessor even if they see the interrogation and hear the expert testimony, and too late because, even if the jury acquits, great harm will already have occurred”

The Salem Witch Trials In The Crucible By Arthur Miller

In the United States there is a law that states "Every person is presumed innocent until proven guilty,” Title II, Chapter 1, Article 29. This law it allows the people to fight for what they were accused of until either proven guilty or proven innocent. Unfortunately, this does not stop people from making up answers to crime that they accused just to get answers. People want the answers now, so they will believe anything that they hear. If someone is accused, but did not confess they will pressure them to confessing, even if they didn't do the crime.

Due Process Model And Crime Control Model In The Criminal Justice System

909 Words | 4 Pages

The principle in law that one is innocent until proven guilty has created much discourse. There are those who feel that the moment that one is arrested, there is reasonable belief that they committed the crime. However, there are those who feel that just as the principle states, one is, and should be taken as a victim and the outcome could be either way: guilty or not guilty. In fact, this argument is supported by the many cases of malicious prosecutions and mistaken identities.

Innocence Project Thesis

1227 Words | 5 Pages

Since the founding of our judicial system there have always been individuals claiming innocence to a crime that they have been found guilty of, traditionally, after their sentencing no matter how innocent they may or may not be would have to serve, live and possibly die by the decision of their peers. The Innocence Project, founded in 1992 by Barry C. Scheck alongside Peter J. Neufeld faces this issue by challenging the sentencing of convicted individuals who claim their innocence and have factual ground to stand upon. The Innocence Project uses the recent advances in deoxyribonucleic acid (DNA) testing to prove their client’s innocence by using methods that were not available, too primitive or not provided to their clients during their investigation,

The Importance Of The Fifth Amendment

480 Words | 2 Pages

The fifth amendment to the United States constitution should remain just as it is, meaning that no person should be forced to provide incriminating evidence against themselves. And to do so would go against the natural law of self preservation. But by not compelling a person to provide evidence against themselves offers one relief from perjury in order to preserve themselves. The speaker equates not answering to lying which is incorrect, the speakers strawman example of not answering a spouse is an untruth and is an unrealistic example.
