DNA Profiling Used in Courts
DNA profiling is a technique often used to identify criminals or the
biological parents of a child through the analysis of their
deoxyribonucleic acid (DNA). The technique is very successful as it is
based on the fact that every person possesses their own individual set
of DNA, which is unique to them with the exception of identical twins.
DNA found in materials such as blood, semen, bone and hair is
extracted for analysis. There are issues involved in its application
as it can be seen as an invasion of ones privacy through the use of
DNA banks. Recently there has been some speculation about the accuracy
of DNA profiling leading to concerns regarding the potential for
criminals to have been falsely convicted. The cost of DNA profiling is
very expensive making it inaccessible to some people. There is also
potential for the misuse of DNA profiling.
There are several different techniques of DNA profiling currently used
today. I have chosen to investigate the most common type of DNA
profiling, restriction fragment length polymorphism (RFLP). The first
part of the process is called restriction digest. Firstly the DNA is
broken into pieces using an enzyme called Hinfl. This enzyme, which
comes from the bacteria Haemophilus influenza, is able to recognise
and break DNA whenever a sequence of GANTC appears. GANTC stands for
the bases that are found in DNA (Guanine, Adenine, Cytosine and
Thymine). The N stands for any nucleotide (phosphorus and sugar). The
pieces of DNA are then sorted by size using electrophoresis. DNA
particles are placed into an agarose gel and an electrical charge is
applied to gel. A positive charge is applied to the bottom and a
negative charge to the top of the gel, which is able to conduct
electricity. The negatively charged DNA particles are attracted to the
bottom of the gel. The smaller fragments of DNA move quicker so they
will be found at the very bottom of the gel. Heat or chemicals are
used to break the DNA into single strands, which involves breaking the
Did you know that almost everything you do on the internet is being tracked and recorded in some way? In the Article, George Orwell… Meet Mark Zuckerberg, by Lori Andrews, Andrews talks about how behavioral advertising, which is the tracking of consumer’s online activities in order to bring custom-made advertisements, is a topic that is concealed to many people and can cause damage. Search engines like Google store the searches you have made and in 2006 there were search logs released which had personal information that people were judged by (Andrews 716-717). Data aggregation is the main way Facebook makes its money. Andrews believes that it’s an invasion of privacy and is not known well enough by the public. This article is aimed at young and new internet users that are ignorant of the possible dangers on the web. Lori Andrews is successful at informing novice users about the dangers of behavioral
. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a large number of individuals released or convicted of crimes based on DNA left at the crime sceneDNA is the abbreviation for deoxyribonucleic acid. DNA is the genetic material found in cells of all living organisms. Human beings contain approximately one trillion cells (Aronson 9). DNA is a long strand in the shape of a double helix made up of small building blocks (Riley). There are four types of building
..., websites and online marketers do find ways around users’ precautions to gain personal information. There are many people out there who want to use personal information like credit card numbers or addresses to cause harm to others. These cases are the extremely negative ones that people want to and should avoid. The case of companies and third parties tracking browsing history and other information for advertising purposes hover over a finer line between good and bad. For some people, tracking can be considered convenient in terms of shopping for what they are interested in, and others may be uncomfortable with the thought of being tracked without knowing. As stated in the beginning, complete privacy is unlikely, but being informed about the tactics of the Internet can help one protect themselves and others in their care to be as careful and private as possible.
It is the way of life in this age, to search the internet for leisure, research and general amusement. When you are not able to communicate with someone face to face, you pick up the phone. When you venture out of your house for any reason and into populated areas, you are recorded by businesses, photographed by red light cameras, and recorded by traffic cameras. The government has the capacity to watch all of this use. Last year, Edward Snowden’s leaked documents proved it that Big Brother is indeed watching. (Orwell 1)
Abstract; This paper explors the effects DNA fingerprinting has had on the trial courts and legal institutions. Judge Joseph Harris states that it is the "single greatest advance in the search for truth since the advent of the cross examination (Gest, 1988)." And I tend to agree with Judge Joseph's assertion, but with the invention and implementation of DNA profiling and technology has come numerous problems. This paper will explore: how DNA evidence was introduced into the trial courts, the effects of DNA evidence on the jury system and the future of DNA evidence in the trial courts.

Privacy is a complex concept with no universal definition as its meaning changes with society. Invasion of privacy occurs when there is an intrusion upon the reasonable expectation to be left alone. There has been a growing debate about the legitimacy of privacy in public
The personal connection Americans have with their phones, tablets, and computers; and the rising popularity of online shopping and social websites due to the massive influence the social media has on Americans, it is clear why this generation is called the Information Age, also known as Digital Age. With the Internet being a huge part of our lives, more and more personal data is being made available, because of our ever-increasing dependence and use of the Internet on our phones, tablets, and computers. Some corporations such as Google, Amazon, and Facebook; governments, and other third parties have been tracking our internet use and acquiring data in order to provide personalized services and advertisements for consumers. Many American such as Nicholas Carr who wrote the article “Tracking Is an Assault on Liberty, With Real Dangers,” Anil Dagar who wrote the article “Internet, Economy and Privacy,” and Grace Nasri who wrote the article “Why Consumers are Increasingly Willing to Trade Data for Personalization,” believe that the continuing loss of personal privacy may lead us as a society to devalue the concept of privacy and see privacy as outdated and unimportant. Privacy is dead and corporations, governments, and third parties murdered it for their personal gain not for the interest of the public as they claim. There are more disadvantages than advantages on letting corporations, governments, and third parties track and acquire data to personalized services and advertisements for us.
This paper explores deoxyribonucleic acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore, the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell, Krauss, Liberman, Miethe, 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is collected, the effects that is has on a juror and the pros and cons of DNA collection in the Forensic Science and Criminal Justice community.

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.
Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem repeats are also the same for all people, but the number of repetitions is highly variable. Before this discovery, a drop of blood at a crime scene could only reveal a person’s blood type, plus a few proteins unique to certain people. Now DNA forensics can expose a person’s gender, race, susceptibility to diseases, and even propensity for high aggression or drug abuse (Butler, 2011). More importantly, the certainty of DNA evidence is extremely powerful in court. Astounded at this technology’s almost perfect accuracy, the FBI changed the name of its Serology Unit to the DNA Analysis Unit in 1988 when they began accepting requests for DNA comparisons (Using DNA to Solve Crimes, 2014).
Millions of people resent the government for being somewhat of a Big Brother, making accusations of spyware programs and hacking, supposedly regulating our every move, yet freely share exceedingly personal information publicly. It has become common practice to post about your family members, location, phone number, email address, workplace, political affiliations and so much more, reaching far beyond the simple question “what are you doing now?”. Although many sites like Twitter and Instagram have a delete button, your postings are in actuality never erased permanently, but instead are gone from your so-called timeline. Daum notes in her essay that, “in a world without boundaries… privacy as a cultural or even personal value has been going out of style for quite some time now” (233). It is almost hypocritical in a way how our society pretends to value secrecy and discretion, yet people of all walks of life exhibit very little self restraint when it comes to filtering the kinds of information they post about
There has always been surveillance of the general public conducted by the United States government, the usual justifications being upholding the security of the nation, weeding out those who intend to bring harm to the nation, and more. But the methods for acquiring such information on citizens of the United States were not very sophisticated many years ago, so the impact of government surveillance was not as great. As a result of many technological advancements today, the methods for acquiring personal information - phone metadata, internet history and more - have become much simpler and sophisticated. Many times, the information acquired from different individuals is done so without their consent or knowledge. The current surveillance of people by the United States government is unethical because it is done so without consent and it infringes on a person’s rights to privacy and personal freedom.
As technology penetrates society through Internet sites, smartphones, social networks, and other modes of technology, questions are raised as the whether lines are being crossed. People spend a vast majority of their time spreading information about themselves and others through these various types of technology. The problem with all these variations is that there is no effective way of knowing what information is being collected and how it is used. The users of this revolutionary technology cannot control the fate of this information, but can only control their choice of releasing information into the cyber world. There is no denying that as technology becomes more and more integrated into one’s life, so does the sacrificing of that person’s privacy into the cyber world. The question being raised is today’s technology depleting the level of privacy that each member of society have? In today’s society technology has reduced our privacy due to the amount of personal information released on social networks, smartphones, and street view mapping by Google. All three of these aspects include societies tendency to provide other technology users with information about daily occurrences. The information that will be provided in this paper deals with assessing how technology impacts our privacy.
