The Importance Of Fingerprinting

Superior Essays
There are crimes that happen on a day to day basis varying from burglary, murders, and kidnapping. Those that commit these crimes eventually need to be caught and be put behind bars. Catching a criminal is not always the easiest task and many wonder if DNA is the most effect way to catching a criminal (Steen). Without the use of it there would not be the freeing or those accused of a crime and proving of their innocence. In today’s society the use of deoxyribonucleic acid, known as DNA; is the basic building block of life and has aided in identifying criminals and solving major crimes (Houck and Siegel). But on the other hand DNA has also proven many individuals to be innocent of a crime. The information that inside of one’s DNA set in an organism …show more content…
Fingerprinting is used to test ones identify and assess the genetic information of individuals; it is not common for any two people to have the exact same physical fingerprint, which is why fingerprinting is done in forensic science (Houck and Siegel). By having a small drop of blood or the follicle of a hair it can contain plenty DNA that could be tested. There are other examples that contain DNA such as semen, hair, skin scrapings and buts of cigarettes are also often used in criminal investigations. When crimes have to be solved in forensic science; blood semen, skin, and other forms of tissue that can be found on a crime scene can and will be analyzed to prove whether a suspect was there or not and if he or she has committed a crime that they have been accused of. It can also be useful in identifying a body. DNA can be collected and tested in other methods from dried blood, skin, saliva, and urine. Bone and teeth samples can also be used when identifying human remains especially in cases where there is a severely decomposed body. When DNA is left on a crime scene it is sent to a lab for scientists to analyze, the DNA in evidence samples in to determine order if it matches a suspect 's DNA (How DNA …show more content…
In many criminal court cases biological evidence is the main purpose a suspect will or can be convicted of a crime, just by the evidence that is found and the clues that the evidence from DNA proves (Wilson, McClure and Weisburd). One example could be the DNA from semen, found on or in a woman who has been raped; can confirm if a particular man was or was not likely to have been involved. The many samples of DNA that are collected have created oppressive caseloads for DNA that has crimes lined to them that are unsolved (Bond and Hammond). Analyzing DNA from samples such as saliva, skin tissue, blood, hair, and semen is used in a reliable manner; linking criminals to crimes especially crimes like those of rape, murder, and burglary. The technology of DNA is mainly used by police, prosecutors, defense counsels, and courts throughout the United States and it has been accepted more through society in the past decade. With forensic scientist and the improvement of DNA profiling has enhanced the way that law enforcement apprehends criminals. Before this process of DNA profiling, law enforcement had to only fingerprints and circumstantial evidence to convict. With the use of DNA profiling gives detectives and other law enforcement solid proof to use in convicting and allowing the case that is trying to make a strong and solid case. Using

    Forensic DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the 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 testing to successfully identify the perpetrator.…

DNA in Forensics can be used to identify criminals in cases where the suspect is known and also in cases where the suspect is not known. For example, DNA sample from a suspect who has been arrested can be directly compared with DNA sample from the crime scene; on the other hand, DNA samples from the crime scene can be matched with DNA samples archived from other crime sense and already prosecuted cases. Although the DNA collection and analysis system needs great improvement, the system has been used successfully used to prevent the most heinous and violent crimes form taking place and has also helped convict most dangerous criminals involved in a series of different crimes (justice.gov, 2014).

Criminal profiling has proven to be a useful tool in law enforcement in solving violent, apparently motiveless crimes. The process has aided significantly in the solution of many cases over the past decade.…

    Some may say, conventional fingerprinting is part of DNA profiling but they actually have great differences. Even though, fingerprinting may be the easiest way to identify a person, there are many limitations to it over DNA profiling. Today, criminals are aware that fingerprinting relies on the presence of a finger impression and wear gloves. In contrast, DNA shed at a crime-scene can be extracted from many sources and used to generate a DNA profile (Edmonston 2). Edmondston goes on to say, DNA can be extracted from one single cell, including from partial fingerprints that can not be identified and fingerprints also can not be obtained after any type fire or bombing in any type of crime-scene.Any technique that is used to identify someone is very useful in discovering who that person is or if someone was part of the crime committed but overall, DNA profiling is the best technique over conventional fingerprinting when fingerprinting is…

    The leading concern of holding everyone’s DNA fingerprints on the database is the privacy of individuals and their personal rights. Your DNA contains all of your genetic information including being susceptible to certain diseases and if anyone were to gain access to this for example your insurance company, this could lead to discrimination. Although DNA evidence can be exceedingly helpful in a criminal case and can lead many cases to be solved, DNA can also be planted which then can lead to innocent people being convicted. If DNA fingerprinting was to be implemented, then the impact of the DNA will become even stronger than it already is. As it is already swaying judges extremely strongly, if this becomes easier to access it will be almost undeniable.…

    Criminal Profiling: More than Movie Magic Aspects like age, marital status, ethnicity, and identifying characteristics are what define a typical criminal profile and are crucial in catching serial criminals. Criminal Profiling has made a debut in the media with shows like Criminal Minds and novels like Sherlock Holmes, but the science behind profiling is often left to the imagination to create the idea of a profiler as a magical and all-knowing being, when in reality they are highly trained individuals with great attention to detail. Due to the relative newness of the field, many people are skeptical and profilers have been under scrutiny by the general public as well as law enforcement for years, which left them with a fortuneteller-like reputation.…
