The science of forensic investigation has become a highly popular tool in law enforcement in today's time. It has proven to be useful in sometimes locating evidence that proves the innocence of those thought to have committed a crime. Also it works to prosecute those who are irrefutably guilty of committing violent and criminal acts against other human beings. Although offenders might go free for a certain period of time, forensic techniques are gradually minimizing those possibilities of getting away and remaining free once a crime has been committed. For instance, one stray hair or a cigarette butt with a lip imprint left on it can be the clue law enforcement needs to apprehend a possible suspect in relation to a murder, rape, burglary, or possible other heinous act against those in society. In fact, some researchers state that forensic science has made all the difference in how the criminal system now works in the United States.
DNA data banks are worthy tools in legal investigations due to the fact that if a previous offender commits another crime and gets away, the forensic evidence can be analyzed and compared to information stored in the DNA data banks. Often times this hurries the process along and provides the necessary means to apprehend a previous convicted criminal of a serious crime against another (Office of Forensic Services 2006). For instance, in the case where a young financial analyst was on her way to work, she was confirmed to have been abducted and dragged into a freight elevator where she was raped and brutally beaten, possibly left for dead as well. However, the victim bit her offender and the blood that was left behind on her jacket enabled investigators to pinpoint the person responsible for the crime. Often time's forensic evidence such as this is what it takes to apprehend a suspect. Normally it is the inclusion of skin and hair fibers that are found under the victims fingernails that normally lead to the conviction of a known violent suspect (Office of Forensic Services 2006).
The reason that forensic techniques are highly useful is that they do provide the irrefutable proof of who committed a crime. Now this can't always be 100% for a certainty as there have been some cases that have been overturned. However 99.9% of the time this type of DNA evidence provides the validity needed, as well as the burden of proof that the justice system is looking for to seal a conviction against a violent offender (Office of Forensic Services 2006). Another similar case that utilized forensic evidence was one where an offender actually had a soda in the home he was burglarizing. He went so far as to use a straw which left a good lip imprint. This one small mistake by Angelo Powell, who had a long train of burglaries in behind him lead to his arrest and conviction (Office of Forensic Services 2006). His DNA was taken from the soda bottle he left at the scene of the crime and compared to the stored information in the ...Download file to see next pagesRead More

Significance of Forensic Evidence

... on a victim of rape to determine the person who did the rape. This technology simply collects some fluids from the rape victims for example semen and then it is taken for the DNA test. The results from such tests are in most cases accurate. This has therefore, been of positive significance to criminal justice.

DNA Evidence

The research on DNA evidence started showing significant improvement by the 20th century. DNA evidence became widespread and it became a problem-solving tool for immigration disputes, refining the assay, resolving specimen identity, detecting genetic differences and identifying criminals; thus, the need for DNA identity testing became significant. Historically, DNA evidence began in the forensic field when ABO blood group was used as a system in providing evidence of crime issues. Later, the paternity identification that based on serum protein variation became commonly used. However, it was not until when Jeffrey became a pioneer of DNA based identity testing. DNA evidence became common in federal courts, and the first DNA evidenc...

Forensic Science: DNA Evidence

...Payton Quintina Payton Forensic Science: DNA Evidence Like most of other branches of science, forensic science has been rapidly developing during the last century. "DNA analysis promises to be the most important tool for human identification since Francis Galton developed the use of fingerprints for that purpose". (Committee on DNA Forensic Science, 1996). DNA identification is one of the most valuable instruments for the contemporary criminologists. This type of analysis provides a very high probability of tracing the criminal in case at least some genetic material that belongs to him is present on the crime scene. DNA identification may allow sparing the world from personality violent crimes. If the database would be created that would...

Forensic DNA Testing

... the highest degree of polymorphism are very useful for DNA analysis in forensics cases and paternity testing. Forensic DNA testing is based on analyzing the inheritance of a class of DNA polymorphisms known as "Short Tandem Repeats "or STRs. STRs are short sequences of DNA, normally of length 2-5 base pairs, that are repeated numerous times in a head-tail manner, for example the sequence GATA occurs anywhere between 5-16 repeats at the locus D7S820. The number of repeats within an STR is referred to as an allele. Thus there are 12 different alleles possible for the D7S820 STR. Because there 12 different alleles for this STR, there are therefore 78 different possible genotypes, or pairs of alleles. Specifically, there are 12 homozygote's...

DNA Criminal Evidence

.... However in some jurisdictions, the expert testimony plays a big role in determining the admissibility of DNA as evidence. Personally, I do not agree with the use of DNA as evidence in proving the guilt or innocence of an accused. There are relevant scientific studies where it was concluded that DNA testing is not 100% perfect although the ratio of its reliability reaches one is to 5 million. Criminal prosecution is totally different from civil ones. It is the life and liberty of the accused which is at stake. It has been said that it is better to leave a criminal free rather than punish an innocent man. In this case, no matter how small the percentage of the probable mistake may be committed in the DNA testing and studies, the same...

DNA Evidence and Procedures

Though DNA is used by the body to create the physical characteristics of hair color, eye color, and height, it can only be used to match a suspect to a sample and can not determine their physical characteristics. Advances in DNA technology have revolutionized forensic science since its introduction in the mid 1980s. It is used to bring evidence against a suspect as well as exonerate innocent people.
As investigators, law enforcement is generally concerned with a few key issues with respect to DNA evidence These issue involve maintaining the integrity of the evidence and the credibility of its evidentiary value. These are:
The crime scene is the first line of defense in maintaining credible DNA evidence. To minimize the po...

Analysis of Trust Law Case

Once the court is satisfied that the “declarant had the requisite intention it will strive to validate it.”3 Certainty of intention will therefore be the most important element for determining whether or not the letter constitutes an enforcable trust.

Assuming that the trust held by the trustees under the father’s will trust in favor of Sally and the trust agreement in respect of the horse are valid trusts the question of cetainties are not valid except to the extent that a new trust is created in favor of Sally’s children and thereby extinguishing the previous trusts. This is particularly so with respect to the will trust. The trust agreement over the horse only involves the disposition of a ben...

Analysis of the Case of Hickman v Kent or Romney Marsh Sheepbreeders Association Ltd

There were several basic legal provisions that gave direction to the formation of a company in the United Kingdom. It has its original foundation in 1844 when the Joint Stock Companies Act1 1844 was formulated. It has given regulations for facilitating the formation of companies by "deed of settlement". Gradually, the shareholder concept was initiated in 1855 by the general incorporation procedure in the name of Limited Liability Act2 1855. This has offered limited liability to shareholders and provided identification to the company as a separate legal persona. The doctrine of limited liability postulates that a company shall be liable for the debts that it incurs, and even if it undergoes closure for any grounds, creditors cannot...

The Case of R v Turnbull

The defendants planned to rob a bank’s customer deposits in the bank’s safe by posting a notice diverting the dropbox to another location, which they planned to burgle. Several customers did, in fact, drop their wallets loaded with money into the dropbox, however, one customer was suspicious and alerted the police. The strength of the prosecution’s case rested on the visual recognition provided by a police constable who clearly saw one of the defendants removing a sign from the bank premises and recognized him. On this basis, the court of appeal concluded that the appeal of the defendants could not stand. It was held that if visual identification had been the only evidence, the outcome would not have been definit...

The Idea of Liberty in Sam Slime Case

... Sam Slime This could certainly be the case of the rich get richer and the poor go to jail, especially in a country that is trying to serve many masters. The government of the United States is certainly a political and governmental entity, but at it heart it has almost always been a voice of corporate business and expansion of wealth for the few. It operates seemingly under the principle guise of what is good for business is good for the people. One could say that the state of the economy today is the fallout of this mindset. In the “Sam Slime” case study we see the idea of liberty as applied by several masters. The first, when Sam Slime mugs you outright is a matter for governmental law and order.

Analysis of OReilly v Mackman Case

Judicial review is a concept which is constitutionally undecided as it on one side, it shores up the rule of law, democracy, and pre-eminence of parliament by facilitating the courts to check the boundaries of government authority and on another side, the courts are open to the decision on the plants based on the fact of separation of authorities that are intimating with the verdicts of democratically elected institutions. Judicial review is not apprehended with the virtues of government assessment but deals with whether the deciding authority has remained within the legal boundaries and whether broad principles of rationality and fairness adhere. The constitutional basis of judicial review is debated as one view holds that it is...

Forensic Mental Health

In contemporary society, we do have a moral obligation to treat everyone who enters the criminal justice system fairly. However, there are two aspects of this argument that seem to be developing. On the other hand, someone who does not have control of themselves because of mental illness may need to be seen differently than what has been set for "normal" criminals. The literature points in both directions and this can be a difficult call when people are actually entering the system.

In the current literature, the current criminal justice system has specific ideas of what should be done when an individual commits a crime. As an example, Carvan (1999) poses a question in a case study that is pertinent to the shit study. I...

Apparently, there was, when considering their verbal and written mail sent by Richard to Holy Farm on August 1 reading as follows –“Please deliver 20 boxes –Granny Smith ‘Brighton Greens’. Cheque mailed.“

It may be seen that the mail order does not specify the category or grade of apples to be supplied, but one of the implied conditions of sale could be that the goods ordered need to correspond with the goods inspected and tested.
