Introduction to Forensic Science Essay

An investigation involving a firearm is a specialty of forensic science which focuses on the examination of firearms linked to ballistics. Ballistics is related to finding out the exact flight path of projectiles. Ballistics is the area of study that examines the exact path of the bullet from the moment it leaves the muzzle of the firearm up until it hits the target. During examination many items are collected for evidence including the firearm, bullets, live ammunition, cartridge casings, trace materials such as powder residue, and anything damaged by the projectile. Firearms are often divided into three processes: Internal, External, and Terminal Ballistics. Internal refers to the inside of the firearm; the space of time in which the shooter pulls the trigger, and the when the bullet is exiting. External ballistics is the flight between leaving the muzzle of the firearm, and it striking its target. Terminal ballistics is the impact of ballistics that refers to the examination in which the projectile strikes a target. All firearms leave markings on the cartridge casings once expelled when firing. Ballistic identification and microstamping laws make it possible to link a cartridge recovered to the

Forensic ballistics and firearm investigation begin when the bullets, cartridges, a weapon, or any combination of the above found at a crime scene. With the evidence, a crime laboratory will explore for clues on some things that might cause a suspect or possible to prove that the things were used in the crime. By contrast, the markings on the bullets or cartridges found at the scene with those discharged from the suspect’s weapon, a ballistics expert will typically confirm if the rounds came from a similar weapon. Just the act of cycling a cartridge through the weapon without firing it will leave permanent scratches on the case that is distinctive to the weapon.

How must it be to live in a criminal mind? How must it be to completely loose the sense of normality? I heartily believe that Forensic Psychology holds the key which opens an entire world of psychopathologies, mental deformities, twisted thoughts and repressed needs of bestiality. Besides letting you sink into the most dangerous minds, it gives you the armament to combat everything hiding in there- knowledge.

To record a crime scene, forensic scientist can use photography, drawings, and videography. Photographs are an important record of the unaltered crime scene, Drawings or sketches provides valuable information when a photograph cannot accurately depict the scale of a room or the relationship of items to each

Forensic science and law are often seen as two opposing disciplines; forensic science is often presumed to be factual and law can be interpreted in multiple ways. Science and law reach conclusions in different ways which is an issue. Due to these differences, miscommunication is often the cause for miscarriages of justice. In order to address this problem, people working in the criminal justice system should have more knowledge of forensic science. There are many factors that contribute to the lack of understanding between forensic science and the people involved in the court process. Firstly, the adversarial model will be discussed in relation to how these procedures prevent effective communication between forensic evidence and lawyers. Secondly, the role that expert witnesses play in the presentation of scientific evidence and how jurors play a role in interpreting their evidence, will be considered. Thirdly it will be argued that lawyers and judges lack adequate knowledge of forensic science that is needed to conduct accurate trials. Lastly, possible solutions to improve the communication between forensic science and the actors involved in the criminal justice system. Juries, lawyers and judges should be more educated in understanding forensic science.

Nearly anyone you ask would be familiar with the television show CSI. The crime lab is colorful and high-tech with all of the fun toys and machines that analysts use to test the ever abundant amount of forensic evidence from every crime scene. It makes for an exciting drama that you cannot help but get immersed in—it also gives us a false illusion, however, creating what has been dubbed as the “CSI effect” (Baskin, 2011). This effect describes the idea that crime shows such as CSI generate unreal expectations, making viewers believe that forensic evidence should be existent in all criminal trials, therefore affecting their overall perspective on a case (Baskin, 2011). But in reality, forensic labs are not that glamorous. In fact, the

Forensic Science has contributed to our world a great deal. People often misunderstand Forensic Science and believe it is much more capable than it really is. As a matter of fact what you see on T.V. is around 80% false or over exaggerated in some way. To Start of, Criminal Investigation is the largest and most known form of Forensic Science. Some of the more known areas include; Fingerprinting, Ballistics, DNA Identification, Fiber Samples, Computer Animation, Documentation analysis, etc. To get this out of the way in the beginning, what you saw on last night’s law and order is far from the truth. Things they do in a matter of hours take months at a time, and most of the time aren’t even plausible concepts.

Forensic anthropology is a subfield of physical anthropology that aims to assist in the identification of human remains and to help determine what happened to the remains (Ubelaker, 2006). A forensic anthropologist is able to aid law enforcement by narrowing down the list of possible victims. This subfield of anthropology consists of several processes and a vast list of duties that are important in providing positive identification.Even though forensic anthropology dates back many years, major advancements in this field are still being made today.

The Insanity defense is mentioned as confusing to the psychiatric and legal concept. Furthermore, it is explained that the word “insane” is more of a legal word, then a medical term, and therefor to prove a person or a criminal insane, one must find the mental condition, of a criminal, severely impaired to the point of losing one’s free will. A psychiatrist may be or may not able to determine such illness, and a jury’s decision solely based on a psychiatrists’ opinion may be grounded on unreliable evidence.

I think the interesting thing about working with firearm evidence is learning about different types of weapons, identifying different markings on bullets and learning about the bullet trajectory and distance. The challenging part would be examining bullets that are broken or mutilated.

1). Forensic Psychology is the application of the theories of psychology to law and the legal system. Issues of violence and its impact on individuals and/or groups delineate the main and central concerns in Forensics within the adult, juvenile, civil, and family domains. Forensic psychologists provide advice to legislators, judges, correctional officers, lawyers, and the police. They are called upon, for example, to serve as an expert witness, diagnose and treat incarcerated and probationed offenders, and screen and evaluate personnel in the law enforcement and judicial systems. Forensics encompasses a wide range of academic orientation. Synonyms for Forensic psychologists include criminal psychologist,

After doing their job in he crime scene, the evidence they took will be taken to the forensic scientist. Crime scene investigators will look at the photographs and connect their theories based on the crime that occurred. The forensic scientists will also examine the victim’s clothes, while the medical examiner will analyze the victim’s body for more clues and evidence that they may find and they will all be doing this in the crime lab. The things they may find could be hair, fiber, semen, blood, another person’s DNA, bruises and many more. After the forensic scientists
