Essays on Forensic Science

Chromatography is a laboratory method or technique to separate various compounds such as inorganic or organic substances for further analysis, evaluation or testing (Chavan et al. 283). It is an important tool since it could be used in numerous fields of sciences. It provides a way for analyzing mixtures or solvents which could not be easily separated through physical methods. It is also an important method due to its simplicity. One of the most important applications of chromatography is its use in forensic science or other types of investigation. This method is often used in analyzing substances which are ...

Forensic evidence and probabilistic reasoning has recently become a significant aspect of criminal laws assessment. Consequently, this has expanded the analysis, prosecution, and hearings of the related criminal acts. However, these are accomplished in relation to forensic science evidence, which mostly entails DNA-related features produced by skilled witnesses. Therefore, it is important to ensure that every individual involved in unlawful adjudication is in a position to fully assess and comprehend forensic evidence appropriately. Concerning the provided test and assessment, there is a positive correlation of the basic features of the sampled specimen under study. As observed from the osteological ...

DNA in Forensic Science

Forensic Science deals with investigations of suspects or criminals in crime scenes legally. In most cases, there are usually a lot of people involved in crime scenes. Some of them being innocent while some are the criminals. Also, there may be one criminal involved in an incidence. In Forensic Science, DNA is used to differentiate the individuals so that the criminal among them can be known. Additionally, DNA analysis is performed in the paternity testing. It enables the determination of a parent or parents of a child. DNA analysis is now being regarded as scientific evidence ("Application of forensic ...

Permanence and Uniqueness are two principles used in understanding the embryology and physiological development of friction ridge skin. The uniqueness and permanence of friction ridge skin have been applied as one of the fundamental factor used in fingerprint identification in forensic science. Fingerprint identification, analysis and comparison play a significant role in forensic science for solving criminal cases. It is imperative to note that friction ridge skin possesses unique attributes that persevere from before birth until decay after death (Edelmann & Denton, 2007). These two principles of unique attributes and their persistence from before birth until decomposition after death are ...

A Look at the History of CSI

Dynell Trudell Saint Leo University Abstract “Forensic science” is the applying of science to civil and criminal laws. “Forensic Scientists” assemble, conserve, as well as examine scientific proof throughout the way of an investigation. A few “Forensic Scientists” actually go out to the scene to gather the proof themselves; but rather engage a laboratory position, performing studies on subjects brought to their place by other people. Furthermore, “Forensic Scientists” give proof as unique observers in all cases and may work for either the resistance or the indictment. This paper will show the development of Crime Scene Investigation techniques and ...

When attempting to find trace amounts of an inorganic substance x-ray diffraction would be a valuable tool for discovering just what substances were present. It would not be the first choice according to various researchers, but it would be one of the least invasive as well as one of the least likely to destroy the sample. By using x-ray diffraction it is possible to differentiate between substances, making it easier to identify trace elements that can be found in crime scenes. X-ray diffraction is a valuable but slightly limited technique that is used by forensic science thanks to its ...

There has been a large demand for the continued advancement in forensic science for quite some time. Though much of what went into the practice wasn’t fully understood until the early 20th century. Until then forensic specialists were largely self-taught and not as highly regarded when it came to their role in law enforcement. Forensic science is a boon that has revolutionized law enforcement. According to The History of Forensic Science (2011) the first classes to teach the subject weren’t adopted until 1902. It also wasn’t until the 1930s that the course began to catch on ...

Introduction Thesis Statement: The use of DNA in a criminal prosecution has helped advance justice for both victims and suspects by, among other things, eliminating the possibility of wrongful conviction due to inaccurate identification. This way, it has also tremendously helped the law enforcement agencies in the criminal justice system in fighting and solving crime through effective investigation of offenses. However, there are also legal -particularly human rights- and ethical challenges regarding DNA application in criminal prosecution (Naughton & Gabe 245).

Introduction

Blood behavior conforms to specific scientific principles and therefore, professionals trained to perform bloodstain pattern analysis can analyze the blood evidence in a crime scene and come up with conclusions as to how the blood shedding happened. The stains may appear to have a random distribution in a crime scene, but the analysts can study the spatter patterns, transfers, and other marks. From the physical evidence, the investigators recognize and interpret the patterns to determine how they were created. These marks are then categorized to recreate the sequence of events that occurred following the bloodshed. Blood stain pattern analysis, ...

Abstract

Forensic Science has long found important application in a criminal investigation, and its correct usage will enhance its effectiveness in crime detection. The use of forensic science in intelligence has allowed the possibility of crime scene reconstruction, identification of a suspect and the elements therein. Law enforcement has gone a notch higher in crime investigation in the sense that scouring for limited evidence at crime scenes has been made possible long after the perfect crime has taken place. The sole purpose of finding the obscure evidence is to have the criminals responsible brought to book and as a result, ...

Ultraviolet light (UV light) is a type of electromagnetic radiation that is located between visible light and X-rays in the electromagnetic spectrum. It is invisible to the human eye, and has a frequency greater than that of visible light but lesser than X-rays. It has a wavelength ranging from about 10 nm to 400 nm (ISO, 2007). UV light is a part of the radiation that comes from the sun. It can also be produced artificially by electric arcs, black lights, tanning lamps and mercury vapor lamps. The name Ultraviolet literally translates to “beyond violet”, as it has a ...

Whereas the need for and application of scientific evidence has become a ubiquitous practice in most criminal justice systems, not so much attention has been paid to the potential limitations and problems associated with this type of evidence. Aspects of forensic technology such as DNA analysis have been used in the identification of the guilty and exoneration of the innocent globally for decades now. However, as the Innocence Project (n.d) notes, whereas some of these forensic technology procedures such as bite mark and shoe print comparisons were developed through thorough scientific research, many of these techniques are yet to ...

Introduction

Evidence takes many forms depending on the trials. Many cases use scientific as well as forensic types of evidence in proving innocence or guilt. Scientific evidence relates to trials in that the evidence is hypothesized, tested, and accepted among the members of the scientific community. Most forensic evidence is scientific, including DNA matching, hair/fiber evidence, and fingerprint identification. Evidence is important in the running of cases as well as ensuring that justice is properly served.

Sexual assault is defined as any coerced or forced sexual behavior or contact that occurs without consent from one of the parties. Some of ...

While the use of scientific evidence in solving crimes has helped in the identification of criminals and the exoneration of the innocent, there are certainly a number of problems that are associated with the use of forensic technology such as DNA testing within the criminal justice system. According to Edmond (2014), the use of forensic medical and scientific evidence within the criminal justice system has in a number of occasions led to wrongful convictions and hence a miscarriage of justice due to the fact that most of them are not reliable. The aspect of the reading from the Innocent ...

Abstract

Actions taken at the beginning of a crime scene investigation can have far-reaching implications in the resolution of the crime, apprehension of the suspects and prosecution in the court of law. Meticulous and thorough investigation is key in ensuring that potential evidence is not destroyed or tampered with and witnesses overlooked. While many criminal investigation agencies employ a wide range of programs, techniques and equipment used in crime scene processing, the resources available and level of training vary from country to country. Apparently, the ability to investigate crimes has improved dramatically over the years with advances in information and ...

The CSI (Crime Scene Investigation) effect or the CSI syndrome is the phenomenon that shows that the media has been spreading serious concerns on the integrity of the criminal trials which are being influenced by the effects of popular television show – CSI (Dioso-Villa, 2009). It is basically the perception that the forensic science results are false as they do not match with the observations in the television show. This syndrome is the effect of the increase in the mass media. This effect started appearing in the year 2003 after the show became popular on the television. Another side effect ...

In the search for justice in the society, there has to be a manner to which things are handled to enhance the outcome or improve the situation in these correctional facilities. To be able to uphold the social control, to mitigate crime and to suction, those that violate the laws there has to be an approach that is taken to how these criminals are handled. The crimes behind these correctional facilities are still human and thus are supposed to be treated like people (Smith, 2011). The introduction of various research programs that help to analyse how these criminals are ...

There are different laws and regulations that guide searching a personal property. One of the permission required searching this workplace is a warrant of search. The American constitution through the 4th Amendment protects private citizens from any manner of search if the searching authority does not have the probable cause for a search (Dutelle, 2016). Therefore to search this property, there is a need to find probable cause to search this facility. As an investigation officer, there is a need to obtain a court order and a police abstract detailing the need for the search and the probable cause ...

(Tutor’s Name) (Assignment)

Introduction The development of science and technology over the last several decades has made crime investigation easier. Agencies like FBI today can identify the true assailant more authentically and quickly with the help of forensic science. It appears that explosive advancements in the area of forensic science have totally changed the way crime investigators approach case enquiry. Prior to the broader development of forensic science, investigation officers were forced to rely increasingly on situational evidences and physical torture to prove the involvement of a suspect in crime. Under such circumstances, fundamental human rights were often ...
