Database normalization

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…

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, unique makeup and the fact that it is stored in a database. The consideration for all members of society is still a struggling issue as the rights and freedoms of criminals are still at risk within the boundaries of the law. It is questioned whether DNA…

The past decade has seen great advances in a powerful investigation tool: DNA. Being DNA is found in every human being, every person's DNA pattern is one of a kind and except for identical twins, no two people can share the same DNA pattern. During a criminal investigation when biological evidence exists, DNA evidence can be used to identify criminals with incredible accuracy. Likewise, DNA can also be used to dismiss suspects or exonerate individuals mistakenly convicted of a crime. Ultimately…

What are the benefits of forensic science? Why is the application of forensic science in courtrooms beneficial? Can forensic science further lead to less cases where innocent people are put into prison for something they did not commit? It is said that "Since 1989, there have been tens of thousands of cases where prime suspects were identified and pursued—until DNA testing proved that they were wrongly accused" (Innocence Project, 2016). It is time, at last, to speak the truth about forensic…

Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of which relate to ethical, emotional, economic and practicality issues. Research states that an increasing number of criminal investigations have used DNA…

This is because the technology has enhanced the quality of evidence collected through increased credibility and reliability. The DNA databases have for example enhanced the manner in which investigators connect crimes with perpetrators.These new developments have made it easier for those in the field to track down criminals and help provide better evidence to support their cases. In some…

DNA databases store profiles of the DNA of those who have been suspects in investigations or convicted of crimes and are useful in matching samples taken from crime scenes. Many people believe that the DNA databanks are an invasion of privacy because it is such personal, genetic information. People are afraid the DNA could possibly end up misused, while others believe that the databanks are a completely useful and practical source for DNA profiling in crimes. The US would benefit greatly from…

When his [Franklin’s son] DNA was entered into the database of convicted felons, detectives were alerted to a partial match to evidence found at the "Grim Sleeper" crime scenes,” (ABCNEWS). It took several weeks of undercover police work to officially determine Lonnie Franklin was the probable culprit in…
