DNA In Forensics

HOW HAS THE USAGE OF DNA IN FORENSICS AFFECTED THE COURT SYSTEM? DNA use in forensic science has made significant impact in criminal justice system over the past decade. DNA does not only play the role of a prosecution toll in the criminal justice system, but it is also used in forensic science as part of the post-conviction review that offers great help in the investigation process (Hauck, 2005). There has mixed feelings about the use of DNA in forensic in relation to the criminal justice system; some people feel that the use of DNA in forensics has helped find more evidence and prosecute criminals while other believe that in some cases DNA might be biased and indicate that the criminal was not involved in the crime because of lack of evidence …show more content…
Based on the existence of biological evidence, DNA tests is vital in ensuring that the criminal justice system is fair and accurate (justice.gov, 2014). DNA in Forensics can be used to identify criminals in cases where the suspect is known and also in cases where the suspect is not known. For example, DNA sample from a suspect who has been arrested can be directly compared with DNA sample from the crime scene; on the other hand, DNA samples from the crime scene can be matched with DNA samples archived from other crime sense and already prosecuted cases. Although the DNA collection and analysis system needs great improvement, the system has been used successfully used to prevent the most heinous and violent crimes form taking place and has also helped convict most dangerous criminals involved in a series of different crimes (justice.gov, 2014). In cases of aggravated assaults, the use of DNA in forensics has helped provide evidence for most cases that had no witness available. For example, according to research conducted, most aggravated assaults are committed by criminals in enclosed environments and large percentages involve cases of domestic violence and sexual assault; these cases involve the victim and the suspects and whether they result in fatalities or the victim survives it is the suspects word verses the victim 's word. In such …show more content…
For example, cases where DNA is used as evidence to help convict the suspect; there are higher chances that the suspect will be convicted at a trial level compared to cases where there are different witnesses involved in providing evidence for the case (Smith & Mann, 2015). Comparing the use of DNA in criminal justice system and use of witnesses to provide evidence indicates that most cases that are free from biases depend on DNA forensics findings to determine the truth in the

    To see how well a suspect’s blood or any bodily material is closely related to evidence that may have been found on the crime scene, DNA fingerprinting allows investigators to evaluate just how well they match. Established in all states, there are DNA fingerprint databases, which all states require the collection of DNA from convicted felons. In order to insure that the information is accurate, there is a procedure that has to be completed in order for it to be a reliable forensic…

    Such evidence includes figure prints, hair, and other forms of DNA. They use this evidence in help to create a psychological profile of the criminal. Criminal profilers would also often time interview serial killers in jail to find other unique patterns between different serial killers. The more criminals criminal profilers study, the more easy it will be to find patterns between serial killers, robbers, and serial rapists will be. One of the many different areas criminal profiling covers includes not just the criminal but also the victim in victimology.…

    The criminal justice system works together in many branches such as police, forensic scientists, and jurors. This was illustrated “Forensics on Trial” in the O.J. Simpson case, when police officers ruined evidence that could have incriminated O.J. and made it impossible to convict him. But forensic scientists themselves have also given forensic science a bad rap.…

    Discovering little details about the killer will help them identify them, and determine why they committed such a horrific act. Criminal profiling is a very effective way to catch criminals involved in violent crimes. The profiling technique has been used by behavioral scientists and criminologists to examine criminal behavior, and to evaluate as well as possibly predict the future actions of criminals (Twisted Minds). Criminal profiling has proven to be a useful tool in law enforcement in solving violent, apparently motiveless crimes. The process has aided significantly in the solution of many cases over the past decade.…

    As regards to The Innocence Project, they state that forensic science resulted in "147 true suspects and/or perpetrators identified. Those actual perpetrators went on to be convicted of 146 additional violent crimes, including 77 sexual assaults, 34 murders, and 35 other violent crimes while the innocent sat behind bars for their earlier offenses." Not only can forensic science acquit the wrongfully accused but it can also help in finding the real perpetrator. As the statistics show, 147 of the real perpetrators have been put into prison so they don 't commit any other crimes which is another benefit forensic science provides. While acquitting the accused, the same forensic evidence allows to find the real suspect.…

    Forensic evidence is evidence obtained using scientific methods including but not limited to, ballistics, blood analysis, and DNA testing. This evidence is extremely important and is used to establish the guilt or innocence of suspects. There are so many tiny parts that go into solving a case. When one thing during an investigation is done wrong, or not found a case can go unsolved very easily. Without the right amount of evidence it is hard to convict a suspect of the crime in question.…

    Not only can genetic databases be of use in the medical field, but also for FBI purposes. With the help of a national genetic database, the FBI would be able to quickly identify missing persons, cadavers, and criminals. The intention of obtaining a genetic database is to solve murders and identify other victims that could only previously be identified as Jane or John Doe. The International Homicide Investigators Association claims that nationally there are more than 40,000 unidentified cadavers. Thomas Callaghan, director of the FBI 's national DNA database program stated that a genetic database would improve the FBI’s capability in solving crime (Willing, 2006).…

    With the provided assumption that the outcome of DNA profiling is this accurate, creating a national database would be a positive thing to the country and even internationally. If all criminals DNA was taken and one of them happened to re-offend, it would be a quick process to find out who committed the crime because the DNA is already on file. Having the DNa on file may persuade the criminals not to reoffend once being released as there is a high chance will get caught. Another positive attribute of having a national database is that it will be an accurate process of analysing DNA at a crime scene. When done correctly, DNA profiling can be up to 99% accurate with only a few sources that error can come from (Australian Law Reform Commission, 2015).…
