Example Of Criminological Science

DNA forensics is a division of forensic science that focuses on the use of genetic material in criminal investigation to answer questions pertaining to legal situations, including criminal and civil cases. Through DNA testing, law enforcement officers are able to identify human remains or the individual responsible for a crime. DNA testing is a highly advanced scientific process that involves replicating the human DNA sequence to create a genetic map of an individual. Because of its reliability, DNA testing has become a significant factor in criminal cases. However, it has also been identified as having the potential to violate privacy and constitutional rights. The DNA identification process consists of five stages. These five stages

On the evening of November 26th, 2000 a sixteen-year-old girl named Leanne Tiernan went missing. She was walking back from shopping with her friend and took a shortcut back home. Not until 9 months later in August of 2001 was her body found. A man walking his dogs in Lindley Woods found her body. Her body was in a shallow grave. Over her was a duvet cover that had a floral pattern. She was wrapped in ten plastic green bags with twine wrapped around them to keep them together. She had three cable ties around her wrists one yellow on one wrist, one black on the other, and a second black tie to connect the other two ties together very much like a daisy chain. She had a plastic bag around her head with a dog collar to hold

From cases such as OJ Simpson to Chandra Levy, DNA profiling also called DNA fingerprinting or DNA typing has played a major role in the criminal justice system. The law enforcement community uses DNA profiling to rule out or identify suspects. Unlike hair microscopy, bite mark comparisons, shoe print comparisons, and firearm tool mark analysis, DNA typing has been developed through massive scientific research and has undergone meticulous scientific evaluation (Innocence Project). DNA is a foolproof method of identifying a perpetrator of a crime.

Forensic science has become the greatest collective method for intelligence gathering of human identifiers. The forensic sciences are used around the world to resolve civil disputes, to justly the enforcement of criminal laws and government regulations, and to protect public health. Over the years, judges have trusted forensic methods without a second thought. DNA analysis is the most reliable method that forensic has, but how reliable is it? (Jonathan Jones, pbs). According to a group called The Innocence Project, “Misapplication of forensic science is the second most common contributing factor to wrongful convictions, found in nearly half (46%) of DNA exoneration cases” (Innocence project).

There are many different aspects of criminal justice policy. One in particular is the different theories of crime and how they affect the criminal justice system. The Classical School of criminology is a theory about evolving from a capital punishment type of view to more humane ways of punishing people. Positivist criminology is maintaining the control of human behavior and criminal behavior. They did this through three different categories of Biological studies, which are five methodologies of crime that were mainly focused on biological theories, Psychological theories, which contains four separate theories, and the Sociological theories, which also includes four different methods of explaining why crime exists. The last theory is

This could be anything like DNA evidence to forensic evidence. A survey was conducted in order to see the correlation between the type of evidence that should be used, and people who watch CSI types of shows. The results showed that 46% of people expected to see scientific evidence in every criminal case, and 22% of people expected to see DNA evidence in every criminal case as well. The findings also indicated that different cases need different types of evidence according to viewers of crime shows. 46% of people expected to see DNA evidence in more violent or serious cases, along with the scientific evidence. In breaking and entering cases, 71% of the people wanted to fingerprint evidence along with the scientific evidence (Shelton,

During chapter 1 of, Basics of Research Methods for Criminal Justice & Criminology, I learned many things related to research. To be considered a good consumer of research, an individual should be knowledgeable about how the research was conducted and how the studies can relate to a person’s department. A good consumer of research in the CJ field would be when a person is able to take past research and understand how it directly relates to policing. An example of this would be if a police officer studied the book, Ethical Dilemmas and Decisions in Criminal Justice, to further their knowledge on ethics in policing. It is important to do this because then that police officer will be more knowledgeable in their field in an ethical standpoint

DNA Fingerprinting, also known as DNA Profiling, is a method used to identify a person using DNA patterns that are specific to him/her. 99.9% of DNA is identical in every human being, but .01% is enough to distinguish between people. It is most commonly used in criminal cases to link a criminal to his/her crime scene, but is also used for paternity/maternity tests, and immigration records. Usually a skin, hair, or body fluid sample is collected from a crime scene or criminal or test candidate, then DNA is extracted and cut using enzymes that recognize patterns in DNA and run through a gel by an electric current in a process called electrophoresis (Annely).

Law Enforcement keep notes on arrests that have founded people innocent of crimes, and retention of an innocent person's DNA can be charge or otherwise, seen as a invasion of that person’s privacy and civil liberties. Dr. Alec Jeffrey, a former professor at the University of Leicester laboratory, consulted with his lawyers to develop the new type of technique called DNA profiling. His technique would prove that DNA fingerprinting (profiling) can individualize evidence compared to the blood typing. DNA profiling compares 13 standard STRs to form a profile. The analysis used by the scientists, uses PCR and STRs to profile an individual. It is highly unlike that two individuals’ identical numbers of repeats for all 13 STRs, will match, which DNA fails is hardly never due to a successful match of 385 million to 1. This makes DNA profiling the most accurate tool in Forensics.

What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus, urine, semen, and vaginal or rectal cells. The DNA found in a person’s saliva is the same as the DNA found in their blood. Parts of the DNA determine our physical characteristics, such as eye and hair color, height, and bone structure, but the

DNA fingerprinting is a technique that is used to determine how likely it is whether genetic material came from a specific person or family group. Since 99% of human DNA is identical, that means that it is only 1% of our DNA which is different, and it is that 1% that we look at when we are attempting to determine the origin of a DNA sample.

Figuring out why people commit crimes is one of the central concerns of criminology. Do most criminals act rationally after weighing the costs of crime? Is society ever to blame for an individual to commit a crime? Do mental diseases or even genetics factor into whether a person will live a life of crime. Over the years, many people have developed theories to try to answer these questions. In fact, the number of theories of why people commit crimes sometimes seems to equal the number of criminologists. I explore these questions and much more in the paper that follow.

DNA fingerprinting is a scientific technology involving the extraction, replication and arrangement of strands of an organism’s DNA. This results in the formation of a genetically distinctive fingerprint that is unique to the organism which the DNA sample was originally extracted from. Because of the specificity of a DNA fingerprint, the application of this technology can have a substantial influence on many aspects of society. Accessibility to a DNA database allows for higher efficiency in forensic investigations, personal identification, maternal and paternal testing. The availability of a national database to police officers and forensic scientists would equate to increased productivity in investigations and prosecution of suspects in a
