[week 1 individual work] | Forensic scientists do much more than process, analyze and compare evidence. The scientist must be qualified as an expert witness. Your individual work will explore the question, "What is an expert witness?" |

The Supreme Court in the 1960’s wanted police to place a greater need on finding evidence that was scientifically evaluated. This led to a growth in the forensic laboratory department. Drug abuse and DNA profiling are also a reason the growth has happened. While the growth of crime and drug use has rocketed, so has the technology used to identify a person as well as the chance to identify a drug and what it is used for or where it was made. Drug abuse cases still outnumber DNA cases, but the DNA experts have made it possible to identify someone based on a bloodstain, semen stains, hair and saliva residues left behind on stamps, cups, bite marks and so on (Saferstein, 2009). Different communities offer different services based on the employees they have and what their experience is in. This is because of the variation in local laws, different capabilities and functions of the organization to which the laboratory is attached and budget and staffing limitations. This is the reason for independent laboratories. Some scientists that work for these laboratories are required to testify about the methods used and conclusions to the evidence at a trial or hearing. When this happens, they have to be considered an expert witness; they could be the ultimate deciding factor in a person’s guilt or innocence. This person has to be an individual whom the court determines to possess knowledge relevant to the trial that is not expected of the average layperson (Saferstein, 2009). This person would need to establish that they have a particular skill or knowledge in a trade

The Expert Witness

...lack of customer trust to the extent this area is not properly addressed. Describe the Expert Witness Trap, i.e. cause, problems generated, and how to prevent it. In litigation, we typically assume that there are two types of witnesses: the fact witness who has direct knowledge of the issues in the case and the expert witness who will use his/her specialized knowledge, skill and experience to assist the judge and the jury to understand the evidence. Most of the time these two witnesses are changed into an expert in a particular field who has first hand knowledge or involvement in the basic facts. This type of witness is called the expert witness. Calling in an expert witness can have pros and cons for the organization. The expert witness can be held in favor of the security manager but in the end the expert witness works for the courts. I think the key to deterrence of loss from the Expert Witness Trap is to first have the credentials and awareness to decrease or exclude the need for one in the first place. The experts should remained focused in various areas of the job and be able to easily communicate their education, experience and abilities. Then, when an expert witness is required, the Security Manager should be able to carefully review a pool of experts, interview them and eventually select ones that are appropriate for their situations. It is critical that such experts are ordered and there is a method to file complaints and pass along experiences through...

Death of an Expert Witness

...Death of an expert witness by P.D James English C Background Phyllis Dorothy James or more commonly referred to as P.D James was born in Oxford in 1920.

Her first published work titled Cover Her Face which she began writing in the mid 50s introduced the public to her most iconic character; investigator Adam Dagliesh. Dagliesh is a well-known character who is a reoccurring presence in a series of detective novels one of which I have had the pleasure of indulging in/reading, namely The Death of an expert witness. Death of an Expert Witness The novel was published 1977 receiving praise from an array of writers and readers. The story opens with scientists and experts in cases of violent deaths being summoned to the scene where a murder has taken place. The victim is a young woman who by the looks of it has been strangled and abandoned in a field. The storyline however does not revolve around the murder in question but is more of a subtle method to introduce the reader to the staff of the forensics laboratory before the murder which the story centres around has takes place/been committed. One is primarily introduced to the forensic pathologist of the Hoggatts Laboratory (located in East Anglia), Dr Kerrison. Kerrison is one morning rudely awoken by the insistent ringing of the phone, careful not to awaken his two young children Nell and William, he quietly leaves the house.

Litigation in the United States ¶8001 U.S. Tort Costs Climbing The U.S. tort system cost $248.1 billion in 2009, which was about $808 per U.S. citizen ($12 in 1950). U.S. tort costs accounted for 1.74 percent of GDP (2.09 in 2002). Increasingly inefficient, the U.S. tort system returns less than 50 cents on the dollar to people it is designed to help; only about 22 cents to compensate for actual loss. ¶8006 A Dispute Begins There are two different courtroom environments: civil and criminal.

Conviction of Wrong Man

...Expert Witness Helped Convict Wrong Man A panel of six independent forensic scientists stated, in a report filed in a Houston State court, that crime laboratory supervisor James Bolding helped convict an innocent man of rape in 1987. Because Bolding either lacked basic knowledge of blood typing or gave false testimony, George Rodriguez spent 17 years in prison for a rape that he did not commit. Bolding’s testimony in the case was challenged amid a scandal that led to retesting of evidence in 360 cases; And with the report filed, that number could increase by the thousands, involving 25 years of cases. “The panel concluded that crime laboratory officials might have offered ''similarly false and scientifically unsound'' reports and testimony in other cases, and it called for a comprehensive audit spanning decades to re-examine the results of a broad array of rudimentary tests on blood, semen and other bodily fluids” (Liptak and Blumenthal, 2004). There have been many cases where forensic science and law enforcement experts have provided sworn testimony, documents, or reports intended for the court that contain unreliable or misleading information, findings, opinions, or conclusions. Some are found to have been intentionally offered by the expert in order to secure an unfair or unlawful conviction, via ‘fitting the evidence to the crime’. A state audit of the Houston police department (HPD) crime lab, completed in December 2002, found that HPDs DNA technicians there...

Legal and Forensic

...then describes some of the typical dilemmas faced by legal and forensic psychologists in the course of their work. The paper concludes with a discussion on the implications of the dilemmas faced by legal and forensic psychologists in the criminal justice system. Introduction Legal and forensic psychologists are a special type of psychologists who are often charged with the responsibility of standing as expert witnesses in court proceedings. The duties, roles, and responsibilities of legal and forensic psychologists in legal matters are strikingly different from those of an ordinary psychologist. It is paramount for legal and forensic psychologists to recognize the obligations as well as the limitations of their obligations when appearing as witnesses in court proceedings. A critical and often murky issue about legal and forensic psychology is how psychologists can double as both a health care profession and as an official in the criminal justice system. This issue revolves around the question of how a psychologist can be able to fulfill his/her legal duty as a witness and still live by his ethical obligation to both the plaintiff and the defendant.
