Forensic Evidence

Improved Essays
This week’s case study requires that we analyze and discuss the 2009 survey of forensic evidence published by the National Institute of Justice (NIJ), in which 2,000 state and local law enforcement participated. (Walker & Katz, 2013, p. 300). This survey revealed that between the years 2002 through 2007, law enforcement had not submitted forensic evidence to a crime lab for analysis for a number of valid reasons; on the other hand, the one reason that I found a bit concerning was that “some police may not fully understand the value of evidence in developing new investigative leads.” (Walker & Katz, 2013, p. 301). I found this reason to be quite surprising as it is in the best interest of law enforcement to use any and all methods of investigation …show more content…
301) Nevertheless, sending forensic evidence to a laboratory may not only confirm the presence of a suspect at a crime scene, it may also serve to identify one that may have been overlooked initially, or just recognize a suspect who has not been identified as such. Another surprising finding from the survey is that: “Three in 10 said they did not submit evidence because they were uncertain of its usefulness.” (Walker & Katz, 2013, p. 301) This response reflects that some law enforcement agencies do not fully understand how they can support the three goals of the criminal justice system that are: “doing justice, controlling crime, and preventing crime.” (Cole, Smith, DeJong, 2013, p. 91) Our textbook says that: “evidence can potentially identify a suspect in a so-called no suspect case.” (Walker & Katz, 2013, p. 301) which goes to support the number one goal of the criminal justice system that is doing justice, in which “we want to investigate, judge and punish fairly.” (Cole, Smith, DeJong, 2013, p. …show more content…
This can be accomplished by the Combined DNA Index System (CODIS) or the latent print database, which are maintained by the Federal Bureau of Investigation (FBI). (“Laboratory Services”, n.d.) By doing this, we continue to build upon the existing evidence databases currently in existence, in addition to sharing that information, which may lead to the discovery of a connection to unsolved crimes around the country. Some of the other reasons noted in the survey for law enforcement agencies not to send evidence to a laboratory included: “the lab’s inability to produce timely results, and not accepting new evidence due to backlog.” (Walker & Katz, 2013, p. 301) In my opinion, these are not sound or valid reasons not to send evidence to a laboratory for processing, and they just fall short of an excuse not to follow through with a thorough

    Despite all of the good that using science in criminal investigation has done. Like all things there have been some hiccups. DNA testing has both enhanced and eroded the status of forensic science in criminal cases. Conventional forensic disciplines were unable to identify a perpetrator with any true discrimination. For instance, conventional serology (the study antigen or antibodies) field analysis of blood group substances was largely used in sexual assault cases during the 1980s (Mosby's Medical Dictionary 8th edition, 2009).…

    Their “goal was to determine if there was any empirical evidence behind the commonly held beliefs that juror expectations for forensic evidence […] are linked to watching law-related television shows” (Shelton). They found that, out of all of the prospective jurors that they surveyed, the CSI viewers had higher expectations of evidence, both scientific and nonscientific, in generally all crimes to be possibly committed. However, contrasting the idea of the “CSI Effect”, the researchers also found that there was little evidence to conclude, “that CSI viewers were either more or less likely to acquit defendants without scientific evidence”…

    Evidence Based Policing

    Introduction Over the years, much has been done in order to improve law enforcement decision making. As a result, evidence-based policing was developed. Evidence-based policing (EBP) is defined as "the use of the best available research on the outcomes of police work to implement guidelines and evaluate agencies, units, and officers"(Schmalleger, 2015). This means that there is research being conducted about police procedures in order to allow police officers to better understand what they are doing right and wrong, which then leads to more effective police work. In other words, evidence-based policing uses research into everyday police procedures to evaluate current practices and to guide officers in future decision making (Schmalleger, 2015).…

    The “CSI Effect” which is the effect of crime television shows on the verdicts made in court cases or on other aspects of the criminal justice system. The perceived rise in acquittals can also plausibly by explained without any reference either to watching CSI or to view crime drama more generally. Tyler (2006), stated, “With an ever-increasing number of crime television programs in which forensic tests are used to solve a case in the course of a single episode. Many criminal justice officials have begun to worry that the public may believe that forensic evidence is easy to obtain, quick to test, and free of potential flaws” (pp. 1050-1085).…

    Evidence Interpretation Over the years, there have been several cases that have been resolved with a false guilty plea or cases where a guilty party was not convicted of a crime. There are various elements that play a role in solving cases; evidence is a one of these key elements. Many factors can determine if the evidence submitted before a court of law is accurate such as how the evidence is collected, if proper protocell was followed before the laboratory’s handling of the evidence, and if the evidences was accurately processed by the crime scene laboratory by various forensic scientists. Furthermore, with the advances in technology in today’s society, various pieces of evidence such a DNA analysis have been considered a crucial element…

    In a homicide investigation, there are many factors which may impact the likelihood of a successful case. In order for a suspect to be convicted on trial, investigative processes must be followed that involve several imperative elements. However, sometimes these procedures aren’t followed and it is in these circumstances that major errors and flaws in the inquiry process are exhibited. It is then due to this that recommendations and frameworks must be created in order to avoid such weaknesses in future cases. Although, sometimes extrinsic factors, such as the influence of the media, may also impact the outcomes of such cases.…

    While the Uniform Crime Reports were ground breaking for tracking crime data nationally, there were many flaws with the system. The Federal Bureau of Investigation would send out paper reports for the local agency to fill out and return. This system leaves a lot of room for human bias, as well as honest mistakes, when reporting crimes. These reasons alone are enough to question whether the reports were an accurate account of crime in the country. Uniform Crime reports also had several other shortcomings that lead researchers to question their validity.…

    It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts’ (Holmes, 2009). Criminal Investigation is a very critical aspect of the Justice System and the wider society in general. For a number of years now, the international media have been criticizing severely the handling of criminal investigations. Some of the issues that have been highlighted are flawed police investigations, which has led to miscarriages of justice (Rossmo, 2009).…

    This is why science such as DNA should be strongly considered to help prove the guilt or innocence of the defendant; it’s essential. In order to fix this issue, there has to be improved police training, video recordings, and provision of expert witness testimony in order to have clearer evidence and confessions. Police reports can be also be sloppy if the officer does not get complete and accurate…

    For Gould this was the most surprising result of his research because he and his team expected strong prosecutorial cases to result in wrongful convictions since the evidence was compelling for the prosecutor to seek conviction but instead the study revealed the contrary. This led the team to look at weak defense counsel, poor explanation/presentation of forensic evidence, and police practices that could trigger the course of events spiraling out of control to a wrongful conviction because the weak prosecution case in turn is not adequately challenged by the defense attorney and the prosecution for one reason or the other may fail to disclose exculpatory evidence- a Brady violation (NIJ…
