Through various techniques of visualization, collection and preservation, hair and fur evidence has made its debut in the forensic science world and in court rooms.

On their part, most legal professionals have lost their own skills and resorted to science. Jurors have been given the wrong impression television programs like by CSI, Bones, and the notion that science will always prevail. Many members of the jury, panels of judges and the bar agree that they need to step up their modus operandi and their reliability on forensic techniques. Groups up against the overindulgence in forensic science such as National Organization of Criminal Defense Lawyers have made campaigns that call for the reforms of the sector. They argue that, over a decade, crime lab investigations have shown that forensic evidence brought before the court is often bogus and is based on speculations, poor quality control, and subjective understanding.
Forensic scientists are always summoned after all the evidence has been presented by the defendant’s lawyer or state that brings out the perception that these scientists hold the key that turns the tide of the case. Coupled with the “CSI effect” bias that was mentioned earlier, jurors are manipulated to depend on science to determine the fate of suspects. The problem is that this number of unfair convictions could even be larger (Begley 12). This is because no studies have been done to determine if different human DNA samples may be similar in structure and might unwittingly link to the wrong person. To that extent, invalid forensic results might have helped to convict the wrong people. The best attempt at forensic science that can be depended upon would be fingerprinting which is better than studying handwritings, dental formulas and shoe sizes.
There has been much criticism leveled at the increased influence of the media on the legal systems in most countries. Of particular importance, is the focus on the forensic methods used to determine whether a person’s DNA or fingerprints were found at the scene or on the victim. Since the adoption of forensic methods in courts, over half of the convictions passed on suspects, were based on invalidated or inappropriate forensic science presented by professionals. First, forensic scientists have been elevated to the level of a juror or a judge in that their recommendations will eventually convict or acquit a person.
Over several decades, technology has significantly improved forensic sciences. One new technology is model. The two- dimensional images of bullets are essentially photographs, often black and white, with a distinct limit of detail. The use of technology has change the methods of analyzing the bullets in firearm examined. Analysis of these projection ballistic can help determine where a weapon was fired, based on shells and cartridges left at the crime scene. Comprehensive ballistic identification system require gun manufacture to test-fire the firearms it produce and store images of the ballistic marking left on cartridges. Imaging for forensic comparison of bullets and cartridge case provides specific advantages in reach. Forensic Investigators are developing and improving databases that identify ridge and groove markings left behind from fired rounds.
When legal matters involve issues outside lay (general public) expertise, lawyers and judges regularlyseek consultation from professionals in a wide variety of fields, including medicalspecialties. Such professionals are often called "experts" or "expert witnesses." Although forensic experts usually are truly knowledgeable, the criteria for "expert" designation in such cases are legal ones, and not necessarily scientific. Sometimes the expertise is sought in an effort to provide the best possibleinformation to judges or juries, but there are many other situations in which a prudentattorney, judge, or other party may request consultation.

You will apply the theories and methods learned throughout the course to create an eight- to ten-page-paper, which includes insight into the role of forensic science, the applications of forensic science for use within the evaluation and/or processing of major crime scenes, and its role in the criminal justice system.
You will provide a comprehensive history of forensic science and a review of a crime scene, including management, security, preservation of evidence, as well as identification and analysis of the evidence. At a minimum complete the following:
Outline of a brief history of forensic science. Include important occurrences, events, and findings that contributed to the development of forensic science, especially as it relates to evidence located and evaluated at your crime scene.
Discuss the actions of the initial response to your crime scene and what processing steps this would include, such as surveys, searches, documentation sketches, etc. Include a discussion regarding where you scene is located and what, if any, Fourth Amendment issues exist that should be addressed.
Identify, collect, preserve, and analyze at least three different pieces of evidence detailed in the above crime scene.
Discuss the analysis of the above mentioned three different pieces of evidence and what information can be gleaned from this type of forensic science.
Summarize the significant findings for crime scene reconstruction as if presenting this case to the district attorney for possible prosecution.

Forensic science refers to the usage of a broad range of sciences to give answers to questions of concern in legal systems and scientific studies. The term forensics and forensic science are used interchangeably to mean the scientific investigation that serves to give evidence to a question from the courts. The science involves the application of biology, physics, chemistry and other branches to come up with unique evidence that eliminates other possibilities and explicitly identifies an individual. The use of forensic science knowledge has been exploited by three main bodies: law enforcement agencies, the media and perpetrators of criminal activities.
Most science term papers need to present a current problem (or even a future problem) and discuss how science can help solve it. You might find that the problem is so new that no one has come up with a theory. If you are in a graduate degree program, your term paper could become the basis for a future thesis.
