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

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.

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
