    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).…

The lack of DNA evidence can help the prosecutors case in the event where an individual who admitted to the crime they have not committed wants to appeal his deal. By admitting to the crime, the court believes that this person has admitted to their wrong doing with no evidence to support the defenses appeal, most jury’s would say no innocent man would admit to something they did not…

    The cold case that I chose in which DNA played a crucial role was the Nicholas Yarris Case. The incident in this case took place in Pennsylvania in 1981(Innocence Project, 2016). The victim in this case was a woman that worked at a mall and was abducted after she got off from work (Innocence Project, 2016). She was then raped and murder; her body was left in a parking lot of a church (Innocence Project, 2016). Four days later Nicholas Yarris was stopped by the police for a traffic violation (Innocence Project, 2016).…

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…

    “Studies have shown that people are less able to recognize faces of a different race than their own (DNA).” In addition, false and/or forced confession is the biggest cause of wrongful sentencing in homicide cases alone. About 63% of homicide cases have been reopened and their “culprit” exonerated because of DNA testing. “Thirty-three of the DNA exonerees pled guilty to crimes they did not commit (DNA).” Occasionally, investigators will have informants in prison give testimony against someone they believe committed a crime.…

    Court systems have many layers, each one of them trying to filter out the innocent, but it is not enough. Something has to be done to stop the number of wrongfully convicted individuals from rising, and release all of the innocent citizens already in jail. DNA evidence can be unreliable and easily tampered with. DNA can become contaminated at a crime scene, or in a lab. This occurs when procedures are not followed correctly, or when the DNA is exposed to harsh conditions.…

    Many different things could go wrong while analysing DNA, such as cross-contamination. Ira Flatlow discussed in an interview that “sampling techniques are changing, so the standard for using DNA evidence should be changing, too.” At a crime scene, you could find fibers, hairs, and maybe even blood that has absolutely nothing to do with the crime that was committed. Someone could use things that has a person’s DNA to plant at a crime scene and have them framed. As crazy as it sounds, it happens.…

    DNA evidence has helped with the innocence of people on death row. Many people are falsely accused for crimes they haven’t committed due to lack of proof to support them. Once DNA evidence was found, many people were not committed for as many crimes and weren’t falsely sent to death row. Before DNA evidence was discovered people were accused for crimes based off of only an eyewitness. There was no real evidence to prove them guilty for the crime.…

    During my process of researching my topic about how bullied students are affected inside and outside of the classroom, I have came upon some amazing articles. One of the most interesting publications that I've found for my topic is an literature review article titled "The role of elementary school counselors in reducing school bullying". The literature review article was an overview of what actions can school counselors take to reduce school bullying. Some of the suggestions that the article give for school counselors is to do more to fight against bullying and become better advocates (Bauman, 2008). I would have to agree with this because some school counselors are not doing enough to help students that are being bullied.…

The author of this article used special Lexis that only the forensic science students, and people interested in that field can understand the overall meaning that is being applied. The author used the DNA sample as an example to show the differences between the time periods it takes in reality to perform the test, and the time period it is shown in the television. In show the DNA analyzes takes 48 hours, but in reality it takes one to two or more weeks for the result to come.…
