Offender profiling

DNA is used to determine paternity test, figuring out deformities in human beings, and even figuring out someone’s ancestry background. But, in the criminal justice field they use DNA for identifying criminals or victims with accurate biological evidence (2014). I do feel DNA testing should always be mandatory. I believe this because when DNA is collected during an arrest this could help take a criminal off the streets and placed in prison or jail. Every crime committed can provide the right…

diseases. DNA is an example of what forensic use for evidence in a crime. Using regions in the DNA you can determine a “fingerprint” for an individual that can help in a crime, with this many forensic sciences has helped law enforcement keep track of offenders. During DNA fingerprinting just, a sample of blood or hair from the crime scene can be used to extract DNA from. Polymerase chain reaction is used to make copies of that STR region because they are being analyzed. Another…

scientist is Sir Alec Jefferys because he developed techniques for DNA fingerprinting and profiling. He's a British geneticist and was knighted for his work. DNA fingerprinting showed variations of the genetic code to identify people. DNA profiling was made more sensitive, compatible with duplication and can be amended to a computer. This scientist is interesting because his method became the standard in DNA profiling. Another person I would enjoy interviewing is Katie Brigance. When I was…

Forensic science still has a long way to go before it can be considered as a science of high degree of certainty. Although it has been beneficial to a certain extent especially with regards to DNA forensics technique which, I will be discussing further in this essay. It nonetheless, has significant implications, forensic science is prone to errors due to analytical and structural defect. Furthermore, most crime labs are not accredited, although there is a choice of being accredited it is not…

One of the advances in fingerprint evidence since Dr. King’s murder has been further study of the ridge comparisons (Saferstein, 2015). A person’s full fingerprint averages 150 ridge characteristics providing plenty of comparison for an identity match (Saferstein, 2015). There have been arguments made that prints collected at a crime scene are not complete, full prints and that could subject the comparison to be invalid because an incomplete fingerprint may only allow for a very limited number…

Fingerprint evidence is highly accurate in the identification of suspects, because the likelihood of two different people possessing the same set of fingerprints is estimated to be one in 64 billion (Hall, 2015). Therefore, state and federal courts universally accept fingerprint evidence during a criminal trial due to the validated science behind the analysis of fingerprint characteristics (Hall, 2015). Next, as with everything else in law enforcement, computers have advanced fingerprint…

My primary interest of study lies in the field of forensic anthropology, in which I will analyze human remains while using a variety of techniques based on forensic chemistry to solve criminal cases. Moreover, forensic chemistry is a field of study that inspires my passion for science, while readying me for a future career as a forensic anthropologist. Ultimately, being an attendant at the Summer Pre-College Forensic Chemistry program at UMass Amherst will allow me to study a field that…

During the 10 through 24 weeks of gestation , ridges form on your epidermis, which is the outermost layer of skin on your fingertips. This pattern on your epidermis is known as your fingerprint. Fingerprint patterns are static and don’t change with age so an individual will have the same pattern from infancy to adulthood. Your fingerprint never changes over time, they will get bigger over time , but will not change. Fingerprints can be very helpful in identifying people. The FBI and many…

Technology has made a major impact on the world we live in today keeping it both current and informative. It serves a great purpose providing various benefits. However, the use of technology can also raise some controversy. The advancement of DNA technology is imperative and it has significantly changed the legal system in the way cases are questioned, investigated and solved. On the other hand, DNA sampling raises issues involving privacy and the violation of human rights due to its personal,…

In modern times, racial profiling is recognized as an important public matter that has drawn and continues to draw the attention of many people, governments, and the world as a whole. Some consider the practice of racial profiling as morally wrong as the division of races and ethnicities seemingly promote racism and supremacy sentiments. Some promoters believe that racial profiling is a healthy contributor to public safety. Others promote its use in all levels of security and law enforcement…
