The use of DNA evidence to convict or exonerate defendants in criminal cases has become increasingly common in recent years, as presented in the cases of the four men in Frontline. This is due to DNA’s ability to identify individuals with precise accuracy. In addition, DNA technology has been improved immensely and has changed the way criminal justice professionals investigate and prosecute crimes. The importance of DNA’s role in the criminal justice system is predominantly seen in criminal trials. DNA plays a significant role in criminal trials, firstly, because of its power to lead to the exoneration of innocent individuals. There are many instances in which wrongfully convicted individuals falsely confessed or made an incriminating
As the incoming brigade commander, LTC (P) Owens, I see the critical leadership problem facing the 4th Armored Brigade Combat Team (ABCT) is the inability or unwillingness of Colonel Cutler to lead and manage change effectively. In initial talks with Col Cutler and in reviewing the brigade’s historical unit status reports, the 4th ABCT performed as well as can be expected in Afghanistan, but as the onion was peeled back there are numerous organizational issues that were brought to the surface while I walked around and listened to the soldiers of the 4th ABCT, in addition to reviewing the Center for Army Lessons Learned (CALL) report. One of the most formidable tasks of a leader is to improve the organization while simultaneously accomplishing
As we learned this week, DNA databases are used by various governmental agencies for several different purposes. We all have seen new magazine shows such as, 20/20 or Dateline, that show the collection of DNA samples from suspects in a case that is compared to those collected at the scene of the crime. But what happens when the sample is an incomplete match, compromised, or contaminated? The answer is the wrongful conviction of innocent citizens. The case that I have decided to highlight, is the wrongful conviction of Herman Atkins. In 1986, Atkins was convicted of two counts of forcible rape, two counts of oral copulation, and robbery in the state of California. It was alleged that Herman entered a shoe store, and raped, beat, and robbed a
PBS’ Frontline film “The Wounded Platoon” reviews the effects the Iraq war has had on soldiers as they return home and transition back into civilian life, focusing particularly on the rise in post-traumatic stress disorder (PTSD) among American military members from Fort Carson Army base (Edge, 2010). Incidents of PTSD have risen dramatically in the military since the beginning of the Iraq war and military mental health policies and treatment procedures have adapted to manage this increase (Edge, 2010). In “The Wounded Platoon,” many military personnel discuss how PTSD, and other mental health struggles, have been inadequately treated (if at all) by military mental health services. Reasons and Perdue’s definition of a social problem allows us to see inadequate treatment of PTSD among returning United States military members as a social problem because it is a condition affecting a significant number of people in undesirable ways that can be remedied through collective action (Reasons & Perdue, 1981).

Deoxyribonucleic acid (DNA) is an acclaimed extraordinary discovery that has contributed great benefits in several fields throughout the world. DNA evidence is accounted for in the majority of cases presented in the criminal justice system. It is known as our very own unique genetic fingerprint; “a chromosome molecule which carries genetic coding unique to each person with the only exception of identical twins (that is why it is also called 'DNA fingerprinting ')” (Duhaime, n.d.). DNA is found in the nuclei of cells of nearly all living things.
In 1989 the National Research Council Committee on DNA Technology in Forensic Science was developed due to numerous scientific and legal issues (The Evaluation of Forensic DNA Evidence). The National Research Council’s key role was to analyze statistical and population genetic issues in the use of DNA evidence and review major alternative approaches to statistical evaluation of DNA evidence (The Evaluation of Forensic DNA, 50). Over the past fifteen years DNA profiling has made tremendous advancements and continuous improvements in the fight against violent

Crime is a common public issue for people living in the inner city, but is not limited to only urban or highly populated cities as it can undoubtedly happen in small community and rural areas as well. In The Real CSI, the documentary exemplified many way in which experts used forensic science as evidence in trial cases to argue and to prove whether a person is innocent or guilty. In this paper, I explained the difference in fingerprinting technology depicted between television shows and in reality, how DNA technology change the way forensics evidence is used in the court proceedings, and how forensic evidence can be misused in the United States adversarial legal system.
“Man O’ War was the kind of thoroughbred that brought you closer to divinity than most people had been before.” This quote by an unknown describes Man O’ War well; “Man O’ War was America’s legendary thoroughbred race-horse” (“Man O’ War 1917-1947”) and was the type of horse that taught his rider, the people around him, and the entire world that if you keep pushing you can reach any and all goals. Man O’ War was a loving horse that made many feel as if they were getting closer to God. To most people, Man O’ War was a work of art that was brought down to them straight from God because he was perfect; he was a gorgeous stallion that seemed to most as unbeatable. Man O’ War raced his heart out and dominated every race he was in, even the one race he lost. Man O’ War was an important figure in the 1920s American history because he changed the perspective of horse racing forever.
Deoxyribonucleic acid (DNA) has been used to analyze and prove innocence or guilt of suspects of crimes with great accuracy. DNA is part of everyday life. It is the heredity material in humans and almost all other organisms. While being part of an investigation. DNA has helped to solve crimes. There is a couple ways that DNA left behind can be tested to solve a crime. Either if the suspect has been caught and or had his or her DNA tested, or if he or she has left behind any biological evidence. Which then needs to be tested to see if it matches the DNA found in the crime scene to his or hers DNA. The result to this comparison may help establish if the suspect committed the crime.
Since DNA technology has been used there has been a high number of individuals convicted, linked or found innocent of a crimes. This technology has helped law enforcement catch suspects that may have never been found without the use of this technology. However, the research reflected that there is a need for clearer interpretations of the DNA results, better equality provided for all regardless of race or class and that errors should be reduced to prevent having cases that need to be exonerated.

Without DNA testing, an innocent person may go to prison for a crime they did not commit and a bad person walk free. DNA is the main part of an individual’s genetic makeup. DNA can be determined by saliva, blood, bones, and even teeth. DNA technology helps the criminal justice system put the right person in prison in a fair matter with proof.
DNA tests provide a foolproof way of proving the innocence of inmates and is an “improved version of fingerprinting”(“DNA”). A scientific lab can conduct tests as long as there is some biological evidence. This evidence may be skin, saliva, semen, blood or hair, which differs for each person, making it impossible to misidentify someone unless the evidence isn’t preserved properly (“DNA”). This evidence has provided those wrongly convicted with a second chance in front of a
