Abstract
The article outlines the development of forensic science over the past 50 years and its growing contribution to crime solving. It also presents some case studies of court cases and deals with the roll of forensic evidence in the courtroom. The author points out that until DNA testing was introduced in the early 1980s the main form of forensic identification was fingerprinting which is not accepted by all as valid evidence.
From the Paper
"Though forensic science has been aiding police work for a long time, it is only in the last two decades that it gained any real prominence. With better technologies being adopted by police departments worldwide, forensic evidence stands a better chance of entering formal investigations. But while these technologies have helped accentuate the significance of forensic science, they have also played a dominant role in discrediting forensic evidence. For example finger printing which is the oldest form of forensic evidence is widely being considered part of junk science that should be kept out of the court. Similarly no case involving DNA matching as primary evidence has ever made it to the Supreme Court in the United States."

Abstract
This discusses forensic science. Forensic science is science applied to law to correctly identify perpetrators and exonerate the innocent. It is accurate and meant to lead to resolution. DNA cloning is an important aspect of science as forensic science involves many different areas of finding evidence in the cause of justice. If misapplied, forensic science can become a curse. Genetic information plays a crucial role and perhaps the most promising role in forensic science.

Abstract
Introduction
Importance of Forensic to Policing
From the Paper
"Forensic science is a science made use of for the intentions of the law, and offers unbiased scientific evidence for use in the in a criminal investigation, courts of law, and a trial. Forensic science is a range of topics, illustrating mainly from chemistry and biology, but also psychology, social science, geology, and physics. Forensic science examples are the use of gas chromatography to categorize detained drugs, odontology practitioners to provide information to help identify a victim's remains that is unrecognizable, and DNA profiling to help classify a murder suspect from a bloodstain or hair obtained at the crime scene (Standfordshire, 2007)."

Abstract
This paper explains that the history of forensic science can be traced as far back as when prehistoric man left behind evidence of fingerprints in early paintings and rock carvings and to the 700s A.D. when the Chinese began using fingerprints to establish the identity of documents and clay sculpture but without any formal classification system. The author points out that a German immunologist Paul Uhlenhuth is believed to have performed the first autopsy in 1901. The paper concludes that forensic science is an important development because it has helped to solve so many crimes which would otherwise have remained a mystery, and has made important strides in solving cases from the past, which have been left open.
From the Paper
"By the nineteenth century, advances in forensic medicine, as it was first called, became much more frequent. Around 1800, Thomas Bewick, an English naturalist, identified the books he published by using engravings of his own fingerprints. In 1810, Eugene Francois Vidoq made a deal with police to establish the first detective force (oddly enough, this deal was made in return for a suspension of arrest and a jail sentence). Also, in 1810, the first recorded use of question document analysis was performed in Germany."

Abstract
This paper focuses on the steps involved in examination of animal hair specimen obtained as part of forensic evidence. Forensic science is being extensively used in crime investigations today and hair can thus provide important clues. But the results obtained after examination may not always be accurate because of the limitations of forensic analysis. The paper discusses these limitations along with the kind of results one can obtain from hair analysis.

Abstract
This paper relates that, although forensic science appears to be a recent development, the modern medical-legal tactic to criminal investigations started in 12th century England when King Richard I enacted the "Office of the Coroner". The author points out that the scientific analysis of evidence left at the scene of a crime such as blood, semen, shreds of clothing, hair, weapons, tire treads and other physical evidence can seem more compelling to a jury than the evidence of eyewitnesses. The paper states that the purpose of crime scene investigation is to help understand what happened and to recognize the responsible person while carefully documenting the conditions at a crime scene and distinguishing all relevant physical evidence for further analysis.

Conclusion
From the Paper
"Few areas of examination at trial can seem as intimidating as the prospect of taking on the prosecution's forensic experts. Crime lab reports seem to have this aura of invincibility about them that lead few trial lawyers to tackle their conclusions head on in front of a jury. Maybe it is because some part of us thinks that the reported results are based upon "science", and science, in turn, can be empirically experienced. Hence, we reason, if the stuff can be checked, no lab technician would put things in their report that could easily be shown to be incorrect. Alternatively, maybe, it is because we simply don't understand how tremendously vulnerable to challenge the crime lab work product really is."

Abstract
This paper examines how although forensic odontology has taken a back seat in the public eye to the notorious DNA, it was at the time, the only forensic technology available during the trial of the notorious rapist and murderer Ted Bundy. It looks at how his heinous fetish of biting, in conjunction with forensic odontology proved to be the most crucial role in "Florida vs. Theodore Robert Bundy".
From the Paper
"Forensic odontology provides physical evidence and gives the judicial system the ability to place, or not place an individual at the scene of a crime. The theory behind forensic odontology is that no two mouths are alike (even identical twins are different), and that teeth, like tools, leave recognizable marks. Thus leading one to believe that, "for a positive identification, only one point of concordance be unique, similar and individual" ( ). "A bite mark, however, in all reality is not an overwhelming accurate representation of the teeth. A lot depends on the mechanics of jaw movement and use of the tongue. Inside the mouth, the lower jaw (mandible) is movable and usually delivers the most biting force, the upper jaw (maxilla) is stationary, holding and stretching the skin" (1)."

Abstract
This paper discusses the three major functions of a forensic scientist. The paper looks at the type of evidence to be retrieved from a deceased victim for examination in the crime laboratory. The paper also describes the proper collection and preservation of paint evidence from an automobile suspected of being involved in a hit-and-run incident.
From the Paper
"Criminalistics is the forensic science of analyzing and interpreting evidence. Forensic scientists examine and identify physical evidence to reconstruct a crime scene. Physical evidence can be a weapon, a piece of clothing, a bloodstain, semen, hair, skin, fibers, dust, pollen, dirt, etc. Criminalists try to use physical evidence to prove a link between a suspect and a crime."

From the Paper
"Forensic Science
The term, "forensic science," encompasses a range of disciplines employed for legal purposes. Depending on the branch of science, forensic professionals may include, among others, physicians, nurses, chemists, and coroners. These individuals' expertise may be applied to both civil and criminal investigations. It can provide a means for determining cause of death in murder investigations, and can also be used to determine suspects' guilt or innocence in cases of sexual assault. Obviously, given the broad scope of the forensic sciences, abundant opportunity exists for those seeking a career in this field. Moreover, of the many different options available, some may be particularly suitable for women.

Fingerprint Classifications in Forensic Science, 2005.
A look at how the classification of fingerprints has been used as a method of identifying individuals for over a century.
2,340 words (approx. 9.4 pages), 5 sources, APA, AU$ 104.95

Abstract
This paper explains that the process of classifying fingerprints is a very sophisticated task that has numerous practical applications in day-to-day activities. The paper further explains that advanced algorithms are used to filter data that contain information about specific anatomic landmarks and these data are matched to fingerprints of individuals saved in databases. The paper also explains that, while the accuracy of this technology is very high, there are up and coming future technologies that may out date fingerprinting as the gold-standard individual identification modality.
From the Paper
"Fingerprint identification has numerous practical applications. Particular fingerprints may be matched to individuals because they are distinct and unchanging. The individuality of fingerprints is based on the ridge structure and minutiae. The recognition of these landmarks, including shape, number, and location is an automated process by which computer algorithms filter data and match a subset of individuals with a particular print. More complex analyses are then performed to identify the individual who matches the print from the subset of prospects. Overall, the accuracy of these technologies is extremely high and is considered the gold-standard for individual recognition. Future technologies such as DNA fingerprinting and iris scan algorithms appear promising and may replace fingerprinting in the future."

Voiceprint Analysis in Forensic Science, 2003.
This paper reviews the beginnings, technologies, courtroom procedures, and results from the analytical technique, "voiceprint analysis."
2,814 words (approx. 11.3 pages), 11 sources, MLA, AU$ 121.95
»
Click here to show/hide summary
Abstract
Voiceprint analysis is the technique, method, and interpretation of listening and visualizing one's voice, usually a known person, comparing that information to a voice sample of a suspect or victim involved with a crime, and coming to a conclusion of whether or not that voice does indeed match the known voice and to what degree of certainty does this analysis conclude. Techniques of the human voice can be cataloged onto a two or three-dimensional surface to be compared among suspects. The court has not always allowed this type of analysis because of testing and proficiency differences among expert witnesses.
From the Paper
"More than one hundred years ago, Alexander Melville Bell, father to the better-known Alexander Graham Bell, believed that someone could be identified by the sound of his or her voice. This theory was put into practice by creating visual representations of spoken words in graph form. When gathering data from different participants, Bell observed and documented that all the participants, although saying the same word and each word followed a distinct pattern, had slight variations. By 1942, different telephone and voice laboratories were able to create a specific device to map ones voice onto a chart or graph. This device, the sound spectrograph, had the ability to construct a physical record of voice patterns derived from frequency, time, and intensity, by evaluating sound waves. This technology (first actively used during World War II in an attempt to identify and monitor enemy transmissions and communications) was not used in conjunction with the judiciary system for suspect identification purposes until 1962-1963, when first put to use in an FBI lab. The FBI needed a new technique to identify specific voice patterns and although Bell had his methods, there was no set method while the methods used had variable accuracy. Therefore, the FBI commissioned Lawrence Kersta to design a specific method in voiceprint analysis. After two years and 50,000 individual voice samples utilized, he designed and created a technique that had an acclaimed 99.65% accuracy."

Outline:
Specific Components of the Behavioral Science Unit and Their Justification
Services the Mental Health Professionals Would Provide to the Department
Structure of the Unit
Conclusion
From the Paper
"Behavioral Science Units have been implemented in police departments across the country to lessen the stress of trauma and reduce the impact of potential trauma an officer may face in the line of duty. It has been determined that a "...systemic view needs to be taken in order to develop effective policy and intervention strategies that will reduce psychological distress and enhance morale among police officers" (Hart, Headey, & Wearing, 1995, p. 156). Implementation of such units is beneficial for the emotional and psychological well-being of officers and should be required of all law enforcement agencies. The mission of the Behavioral Science Unit will be to coordinate employee assistance services for officers and their families, for problem assessment and identification, and if necessary, to arrange referral to other facilities and/or services."

Abstract
This paper examines the breakthroughs made in the field of forensics. The paper begins by providing an explanation of exactly what forensics is and its purpose. The paper then proceeds with a discussion on gathering and analyzing evidence from a crime scene and concludes that forensics make up an immense part of crime solving. Not only can the tools of forensics science help catch terrible criminals, but it can also set the innocent people free.
From the Paper
"First, the scene must be carefully and thoroughly documented in order to preserve the site. Next, a time of death must be established by calculating the drop in body temperature. Once these steps have taken place, the evidence may begin to be collected. While completing all of these steps, the scientist is required to wear protective clothing, so that the scene will not become contaminated . Dr. Edmund Locard, an accomplished forensic scientist, made considerable advancements with his research on two-way transfer. Locard observed that, "Every contact leaves a trace."'
