The Role of Evidence in the Criminal Justice System
I. Introduction
Evidence is the key element in determining the guilt or innocence of those accused of the crimes against society in a criminal court of law. But in order to understand magnitude and necessity of evidence as a it relates to the criminal justice system one must know what are the five (5) key issues and or points regarding evidence. The first is what truly is evidence is it written documentation, is it expert testimony, is it hearsay (oral uncorroborated statements) in a matter of fact way it can be all just mentioned, none just mentioned, or some just mentioned and others as well. After understanding what "truly" constitutes evidence one must realize how and were evidence can be gathered to have the correct overall view of what is and is not evidence. Third all things that may be evidence may be unusable either in defense or prosecution of the defendant. So it becomes essential to understand the ground rules set forth both on the Federal and State level with regards to what evidence is actually permissible in a court of law. Next, we need to analyze to major issues that have become prevalent in our time regarding evidence in the adversary system and the effect recent rulings have had in dictating what is evidence and more importantly evidence permissible in a court of law. Finally, what effect does the process of obtaining, collecting, and using evidence mean for our adversary model used in the criminal justice system?
II. What is evidence?
Evidence as stated by Neubauer, is "any kind of proof offered to establish the existence or nonexistence of a fact in dispute, for example, testimony, writings, other material objects, demonstrations" (536)....

The ruling handed down by the Supreme Court provided a strict interpretation of the fourth amendment, ": "The right of the people to be secure in their persons, houses, papers and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation and particularly describing the place to be searched, and the persons or things to be seized."

IV. What are the major issues facing the adversary system (prosecution v. defense) currently?
V. With our ever evolving society what effect does the process of obtaining and using evidence in criminal proceedings have on our criminal justice system?
Jurors will thoroughly inspect and weigh over the evidence provided, and process any and all possible scenarios through the elements of crime. If the evidence does not support the prosecutor 's argument and the elements of the crime beyond a reasonable doubt, the jury must pronounce the defendant not guilty. If questionable or irrelevant evidence is included in the criminal proceeding, it is the duty of the prosecutor or defendant 's counsel to object and insist that the evidence be excluded by the presiding

I wanted to look at the investigative and criminal procedures following the arrest of an alleged criminal and the powerful effects via testimonies and evidence (or lack thereof) it can have on a case.There is an importance of the courts in regards to crime that can’t be over looked. The primary function of the criminal justice system is to uphold the established laws, which define what we understand as deviant in this society.

Over the next 10 years the criminal Justice system could entirely change with the passing of a major law, epidemic, or failed service. Consequently, every since 9-11 our justice system has become much more open minded. Therefore, resulting in the strict enforcement of laws to protect its citizens. Nothing ever stays the same for too long. New developments related to science, technology, DNA analysis, and countless other tools and other factors are changing for the better in solving cases, prevention of crimes, and aiding in investigations. Where there is change there will be changes in the way we handle everyday processing. For example, booking a criminal, acquiring evidence, and interrogation. This also results in the field of criminal justice having no choice but to adapt to the slowly changing times or else be left behind.
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
...ng to the innocence project, the closed cases from 2004-2010 revealed that 22 percent of cases were closed because of lost or destroyed evidence. That can be a huge number today as it increases. We, as a society think that we are putting away the bad guys, but in reality, do we really know who is guilty and who is innocent? People who give false identifications or statements, people who break the law who are given the authority to uphold the law should be in more trouble than the people who they tried to convict. We are taking away potential victims from their families and homes. We destroy people quicker through the criminal justice system than we ever did in the social world. These are lives that can be saved from the brute and low grounds of prisons as we strip them from their freedom because we were too hasty to overlook the evidence and ask questions.
In criminal justice, detectives need many skills that help capture the suspect. One of the important skills is finding and presenting evidence. This is significantly important because according to the Criminal Justice
4). This is written in a negative tone implying that a change needed to happen in order for them to be more successful; this change being an increase in visual evidence. Expressing a very similar opinion is Michael Diamant, a business attorney. He states the following, “What I’m trying to do with the jury is to focus the issue so they can understand [it] in a clear graphic way, and take away all the noise around it” (INSERT, 2012, para. 6). This will allow the jury to focus solely on what’s important, influencing their decision in the way that the lawyers want it to. Speaking on the contrary to his previous statement, Carney argues, “Lawyers can get overenthusiastic about creating visuals. They forget they have to be directly connected to the evidence.” He then explains that the jury will get tired of it. The jury wants to be engaged and informed. This requires a balance between visual evidence and non-visual evidence. To put the summary of this article into perspective, it’s easy to use an example: the murder case of Susan Wright. Visual evidence will surely help the jury understand the actions that took place on the night of the murder. But what’s important and what’s superfluous? Some important visual evidence for the jury to see
Well written procedures, rules, and regulation provide the cornerstone for effectively implementing policies within the criminal justice system. During the investigational process, evidence collected is subjected to policies such as Search and Seizure, yet, scrutinized by the Exclusionary Rule prior to the judicial proceeding. Concurrent with criminal justice theories, evidence collected must be constitutionally protected, obtained in a legal and authorized nature, and without violations of Due Process. Although crime and criminal activities occur, applicability of policies is to ensure accountability for deviant behaviors and to correct potentially escalation within social communities It is essential the government address such deviant behavior, however, equally important is the protection of the accused which also must become a priority when investigating criminal cases.
The collection, custody and preservation of forensic evidence is a vital aspect of evidence integrity, without proper adherence to these procedures, crucial evidence that could potentially have great impact on a court case could be rendered useless. In the case of criminal proceedings, a skilled defence lawyer will look to scrutinise every step taken by forensic practitioners’ involved within the case in regards to the continuity of the evidence, in doing this they attempt to undermine the practitioner’s ability to properly carry out strict evidence collection, protection and preservation procedures and also look to find fault in the techniques they used to carry out these procedures.
New types of technology have made it easier to track down and catch criminals. Then also made it easier for prosecutors to gather and present more credible information. Some new technology that has made it easier to track down criminals or help provide more reliable and supportive evidence is things such as DNA testing, computer technology, fingerprinting, and GPS tracking devices. “The main strengths of technology in the criminal justice system lie in the provision of databases which allow better and more efficient records to be stored and retrieved” (Bean 370). Prosecutors now in sense have “…an infallible test of truth, a foolproof method, of determining the accuracy and reliability of evidence and hence of convictions” (Pallaras 72). These 4 technological advancement...
Evidence collection is a crucial part of forensics. Its reliability can be compromised by input bias from law
...n of legally obtained evidence and statements. Each and every person involved in the process of the evidence collection and processing must be available for trial. If one of these parties is not available, it may cause some doubt in the juror’s mind, as to what was done with that piece of evidence. The case must be proven beyond a reasonable doubt. In conclusion if any piece of this investigation is not followed by using established guidelines, the outcome will not lead to the successful conviction.
The process of gathering evidence largely depends on the role of discretion by the police. Once police have decided to pursue a reported crime, they then begin the process of gathering evidence. To ensure that the process of gathering evidence is lawful, the police must follow the procedure outlined in the Evidence Act 1995 (NSW), which describes the manner in which evidence can be collected. This act imposes certain limits on the way police can gather evidence and the types of evidence that can be used. The Act is able to protect the rights of citizens by making it a requirement for the police to gain necessary legal documentation, such as search warrants, in order to obtain some types of evidence and thus, protects the rights of ordinary systems. In more recent times, the use of technology has come to play a major role in the gathering of evidence and with this comes complications in the law. New technologies in relation to the criminal investigation process are mainly in reference to DNA evidence, genetic material that can place a suspect at the scene of a crime. The introduction of DNA evidence into the criminal investigation process has been extremely effective in achieving justice, as it is able to secure convictions. Initially, there were some setbacks to the use of DNA evidence
