Dna Technology In Law Enforcement
DNA TECHNOLOGY

How is DNA technology used in law enforcement? There are many different ways it is used, but it is mostly used to solve crimes. Much

like deaths, rapes, or even big robberies. DNA is a way to identify a person by: blood, hair, skin, saliva etc... That is why when people are trying to

discover a murderer they are very careful when they are collecting evidence.That is why when something occurs, everything is blocked off, and

only investigators could pass into the area.While they are invetigating they are looking for any items that might have DNA on it from the killer.

Then they use DNA technologies to " discover" or trace the killer and to find who the victom is or was.

    The evidence collection process is very extensive and must be accurately recorded and preserved. First there should be a plan of action. This includes making sure everyone at the scene knows how the evidence will be documented. If not all are on the same course of action important evidence could be damaged or removed. For example if an investigator walks on a footprint that was left by the suspect it probably won’t be able to get an accurate picture of the evidence and it is lost.…

    Criminal investigators would determine what crime had been committed and if it was located in their jurisdiction prior to proceeding with the case. When this has been determined it would lead to an investigation and as part of the scientific process the issue must be clearly communicated by “stating the problem” (Osterburg 2012). If an investigator is called to a house with a dead body, the problem would be: who killed this person, how was this person killed and why?…

    DNA evidence is a widely used tool in the NSW criminal justice system that aims to help achieve justice. DNA, short for deoxyribonucleic acid, is a long molecule found within the cells of the human body. Each cell contains genetic material in which, apart from identical twins, is exclusive to every individual. DNA though considered a reliable piece of evidence can present many issues in the criminal justice system such as its influence on juries, the issue of maintaining the balance of an individual’s rights with the state’s responsibilities and the issues of DNA contamination, storage and interpretation. These issues will be discussed later.…

    DNA typing was first used in Great Britain for law enforcement purposes in the mid- 1980s. It wasn't employed in the United States until 1987. DNA profiling has changed forensic science. DNA technology has given police and the courts a means of identifying the suspects of rapes and murders. Today, the Federal Bureau of Investigation performs the bulk of the forensic DNA typing for local and state law enforcement agencies. In criminal investigations, DNA from samples of hair, bodily fluids or skin at a crime scene is compared with those obtained from suspected suspects. DNA typing and PCR by court systems around the united states has led many places to pass laws requiring people convicted of sex offenses and other crimes to be DNA typed and…

    Now in order for them to do this they have to first do a walkthrough of the scene to determine what strategy they will need to use in order to apprehend evidence from the scene (work.chro.com. n.d.).

Furthermore, they document the crime scene and all of the evidence that has been collected at the crime scene in order to later be able to testify in court that the evidence in question is from that scene and has been properly documented and collected.…

This is because of higher availability of DNA sources and uniqueness of DNA. Between two people, 99.9…
