Topic: The forensic use of DNA technology. Introduction: This paper discusses the effect of forensic use of DNA technology and importance of using this technology. Due to the increasing rate of violent, The forensic use of DNA technology is essential in this search, hence, this technology enhances the search for truth by helping the police and prosecutors in the fight against crime. Through the use of DNA evidence, prosecutors are usually able to prove the defendant guilt. Some DNA evidence, such as fingerprint evidence offers prosecutors essential new tools for identifying and apprehending some of the most violent perpetrators, mostly in sexual assault cases.
The individualistic characteristic is a key feature of DNA that assists in solving... ... middle of paper ... ...ght crime, but funding sources can slow the process. If funding is not available for states to reduce their current offender backlogs, databases will remain unavailable to aid law enforcement with criminal investigations. . It is up to the criminal justice system is to realize the “full potential of DNA evidence as a crime fighting tool” (Wilson, Forman, & Asplen 1999), efforts must be made both to solve the database backlog of today and to promote DNA evidence use throughout all levels of law enforcement. As criminals become cleverer, evidence like DNA becomes even more important.
There should be no further analysis of the DNA to suggest psychological characteristics that would make the suspect more likely to have cdfommitted the crime. This rule should apply also to samples taken from convicted dfdoffenders for a data vor dagta bank. The pros for having suspects forced to provide samples for DNA testing are few. One is that if DNA is left at the scene of a crime, then if they can get a sample from a suspect and compare, it is a much faster process.
The pattern of the fingerprint may still be similar however it may be harder to automatically search the fingerprint when comparing to an adult size. Also any form of injury to the fingerprinted finger would make an individuals entry into the database in vogue. There are clearly many obvious benefits to DNA fingerprinting babies at birth as this procedure is used in forensic science. It has helped solve many crimes by dismissing suspects and helping to identify and convict the guilty person.
This may be due to a jury’s reliance on scientific evidence, causing them to be willing to convict when DNA evidence is presented, but unwilling to convict in the absence of DNA evidence. This is known as the ‘CSI Effect.’ Juries in US courts also tend to expect DNA evidence in certain crimes, even when it is not relevant, and when it is presented it is often inaccurately used and interpreted when trying to convict a suspect (Shelton 1). Not only can DNA evidence be presented and interpreted wrongly, it can also be inaccurate due to the delicate nature of DNA and the tedious processes conducted to identify it. These inaccuracies lead to wrong convictions, sending innocent suspects to jail or even a death sentence. Often, cases like these are reopened later, and only then do courts realize they convicted the wrong suspect.
FBI profiling People wonder what type of motive a person could have to commit crime. FBI profiling is the act of discovering what is happening in a person’s mind when a crime is committed. FBI profilers try to think like the criminals to help law enforcement catch the criminal and stop from further damages. FBI profiling has always been a passion for people, it eliminates the amounts of stress that can be apparent in the lives of people today. Some of the most interesting and unusual killers will be identified by profiling.
It is also true that DNA profiling can only be used if there is enough DNA in the samples. Crime samples can be compared to a sample from a known suspect or compared to a database of DNA profiling results from other scenes or from convicted offenders. If there is a "match", the two samples may have originated from the same person. While making comparison, the profiles generated... ... middle of paper ... ...make the scientist mad then he could threaten to release this information. One of the main problems with the process of DNA fingerprinting is that the sample can be easily ruined.
Next they would have to search for different forms of evidence, most important would be trace evidence because it can provide DNA evidence which can also link a suspect to the crime. There are many more ways evidence and other clues can be harvested from a crime scene but it is up to the investigator to use their knowledge and help find the person responsible for the crime
Also because of exactly that it can cause problems within a case. The lab could test DNA in a case and find trace amounts of a suspect's DNA for several reasons and it could cause them to take a plea when they learn about it out of fear of harsher conviction, even if they really didn't commit the crime (Kirchner). That person's DNA could be there because they were at the scene of the crime at one point of time, or mis handling of the evidence. There are several reasons why but because of the high sensitivity of DNA testing they were able to pick up such low quantities of DNA na test it. But one false positive or any finding of flaws with the DNA analysis could prompt an avalanche of litigation (Kirchner).
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.
