Advantages And Disadvantages Of Dna In Criminal Investigation

Improved Essays
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.
Serious issues, both positive and negative, arise

As DNA profiling technology advances, DNA evidence is being resubmitted from crimes that were committed years ago and a comprehensive test is conducted to find the potential suspect. Although identifying the perpetrator of the crime may be successful, DNA will have to be taken from other family members. This can cause private information about an individual’s ethnic background or parentage to be available to involved personnel’s which could lead to discrimination. Inaccurate results from DNA evidence has the possibility to put an innocent person to jail. Despite this, small samples are sent to multiple independent labs, which helps to reduce the possibility of an error which affect the final results. As DNA evidence is being passed through multiple labs, the individual’s private DNA information has the potential to be used in different crimes. However, it is stated in an article on “Forensic Databases: benefits and ethical and social costs” that, “Public support has been presumed on the grounds that all law-abiding people want criminals to be caught and convicted and the ‘innocent’ have nothing to fear from DNA technology.” (Forensic Databases: benefits and ethical and social costs, British Medical Bulletin, 2015). It is clear that most of society demands for criminals to be found and people who are deemed not guilty should have nothing to worry …show more content…
(DNA forensics, DNA forensics, 2015). To further improve this system the level of privacy of the DNA profiles on the database should be increased and the number of years in which a DNA profile is kept on the database should be limited to 3-5 years, to ensure that this information is used for criminal investigation only. (Is it ethical to have a National DNA database? YourGenome, 2015) and (Pros and Cons of DNA Profiling, Bright Hub, 2012). The technology involved in DNA testing should also be kept up-to-date to avoid contamination and inaccurate results in identifying the criminal. (How DNA Evidence Works, howstuffworks, 2015). Overall DNA testing should be used to solve criminal investigations, with minor changes to the system, our forensic scientists and other personnel involved in the investigation will obtain accurate results and the worst criminals in our societies will be convicted, making this earth a safer

    Based on the existence of biological evidence, DNA tests is vital in ensuring that the criminal justice system is fair and accurate (justice.gov, 2014). 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). In cases of aggravated assaults, the use of DNA in forensics has helped provide evidence for most cases that had no witness available.…

    For instance, some individuals are wrongfully convicted of a crime in which they were accused of. However, DNA fingerprinting helps reveal the truth accurately and gives that wrongfully imprisoned person another chance at life. Other cons consist of people being worried about being negatively profiled. Because our DNA holds some pretty significant information about us, some individuals see it as one of those cases where people judge you before even meeting you. We all can imagine how painful that can feel and even affect our lives one way or another.…

    Discovering little details about the killer will help them identify them, and determine why they committed such a horrific act. Criminal profiling is a very effective way to catch criminals involved in violent crimes. The profiling technique has been used by behavioral scientists and criminologists to examine criminal behavior, and to evaluate as well as possibly predict the future actions of criminals (Twisted Minds). 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…

    Such evidence includes figure prints, hair, and other forms of DNA. They use this evidence in help to create a psychological profile of the criminal. Criminal profilers would also often time interview serial killers in jail to find other unique patterns between different serial killers. The more criminals criminal profilers study, the more easy it will be to find patterns between serial killers, robbers, and serial rapists will be. One of the many different areas criminal profiling covers includes not just the criminal but also the victim in victimology.…

    In conducting the DNA test, the criminalist is able to extract a genetic “fingerprint,” which can then be compared with the genetic fingerprint of a DNA sample taken from the accused (Garland, 2011 p 135). Both DNA evidence and blood grouping evidence are forms of statistical proof –DNA evidence being the most useful in determining identity. For example, blood grouping evidence may narrow the range of other potential suspects with the same blood type to one out of two hundred, whereas DNA evidence may, as a practical matter, eliminate any possibility that there exists another potential perpetrator by identifying the specific genetic “makeup” of the accused (Garland, 2011 p…
