I was sitting in the old rickety chair that looked as if it had been there for five years. The smell of gunpowder hung in the morning air as I leaned over the rifle rest. My finger wrapped around the trigger as my eye focused through the scope of my grandfather’s Springfield ’03. I took a deep breath and let half out. My finger tightened on the trigger as I awaited the recoil and crack of the gunpowder igniting. Finally, when my finger’s pull was enough to move the trigger, the gun went off. Moments like this are why I love shooting guns.
With my experiences from the gun range, I became interested in the show CSI Miami. The character of Calleigh Duquesne, one of the Crime Scene Investigators (CSI) on the show, intrigued me. She is the ballistics expert. Her job is to investigate crime scenes, testify in court, and work with firearms every day. This job would fit well with my interests in guns.
My grandfather introduced me to guns when I was about 10 by letting me shoot his .22 caliber pistol at the local gun range. He was a Florida Highway Patrolman for 30 years. He loves collecti...
Crime is a common public issue for people living in the inner city, but is not limited to only urban or highly populated cities as it can undoubtedly happen in small community and rural areas as well. In The Real CSI, the documentary exemplified many way in which experts used forensic science as evidence in trial cases to argue and to prove whether a person is innocent or guilty. In this paper, I explained the difference in fingerprinting technology depicted between television shows and in reality, how DNA technology change the way forensics evidence is used in the court proceedings, and how forensic evidence can be misused in the United States adversarial legal system.

“I know what you're thinking. Did he fire six shots or only five? Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: Do I feel lucky? Well, do ya punk?” (Clint Eastwood) From the beginning of wars, hunting, and sport, man has striven to find the most powerful and sufficient caliber for the handiest gun around, the hand gun. Some choose to find a bullet that is uncommon and expensive, while others hunt for the cheapest most common caliber on the market. While there are many bullet sizes, there are two calibers that ring out as the most common yet very different. These two, the .44 magnum and the .45 Colt, both serve sufficiently as hunting and sporting bullets, yet they have characteristics that lead buyers to favor one over the other. Through their history, cost, and uses, it is shown that the .44 magnum and the .45 Colt differ greatly but also share some major similarities.
Crime scene investigators, also known as CSIs, have played an essential role in protecting citizens, by proving who is guilty, and who is innocent. CSIs use a large amount of Science and Math skills to solve crimes, resulting in a decent income. They are specialized in forensic science in order to examine crime scenes and recover important evidence (Career Cruising).
In our communities there are often times when families not only have to undergo the pain that comes with the passing of a family member, but not being able to identify their loved one as well is another struggle they have to overcome at times. Over the years there have been several of occasions where crime scene investigators have been tasked with identifying a deceased individual, while some people wonder what the point of it is and others arguing that it is important for a family. Regardless of one’s point of view, it is very clear that our crime scene investigators have a number of ways to determine a deceased person’s identity.
Forensic scientists work in labs where they examine, identify, and interpret evidence collected in crime scenes. Crime scene investigators collect evidence and pass it to a forensic scientist who uses the items in numerous ways to help catch criminals. Forensic scientists must also record the evidence and any tests ran on it in detail to prove the truth in court. A forensic scientist also has to be able to present his or her physical evidence verbally in court, so a strong communication background is important.
Every week more than 60 million Americans turn their television sets to tune to the popular crime investigation drama CSI: Crime Scene Investigation or one of its countless spin offs, which have become increasingly popular among the American public (Shelton, n.d.). The show has been a top rated drama since it was first aired in 2001, it has received several Emmy nominations, and many even claimed it has lead to the considerable increase in college students studying forensic science. Recently however, despite its many achievements several newspapers and magazine articles began warning about the impact the shows influence is having on our criminal justice system; they referred to the phenomenon as the CSI Effect. Max Houck, Director of the Forensic Science Initiative at West Virginia University, explains the CSI effect as “basically the perception of the near-infallibility of forensic science in response to the TV show” ( Podlas, 2010, p. 99). The concern among criminal justice experts and prosecutors is that the so called CSI effect creates unrealistic expectations that every case must be solved with high tech forensic tests, which they believe, has a significant impact on juror decision making. Exposure to the dramatized and fictional depiction of crime solving portrayed by these television shows has had a significant impact on viewer’s conception of reality, which has negatively altered the expectation of jurors and influenced jury verdicts.
Collecting evidence from a crime scene is a crucial aspect of solving crimes. Before evidence can be seized, there must first be a court order approving the search of the crime scene and the seizure of the evidence found at the scene. Standard protocol for officers is for them to always use latex gloves, avoid plastic bags, double wrap small objects, package each object separately, and to collect as much evidence as possible. It is better to have too much evidence than to not have enough. There are countless amounts of evidence that can be found at a crime scene.

Guns have been apart of my life for as long as I can remember. When I was about six years old my dad came home one day and took me into the back yard. He told me he had something for me and that I needed to be vary careful with it. After I agreed to only using it while he was there to make sure I used it safely, he gave me my vary own BB gun. After a quick safety lesson it was time to start shooting, I had even drawn a target onto a cardboard box. After a few years of shooting and a few thousand BB’s later my dad took me out on my grandparents ranch. After a more serious talk about safety he gave me my first real gun. It wasn’t anything special just a little bolt-action .22 caliber rifle but it was a real gun. My collection of guns has grown over the years but I still shoot that .22 rifle to this day. Since I was younger I always wanted a lever action rifle. So when I turned eighteen I started looking to buy one. I though it was going to be simple just find a lever action and buy it, but as soon as I began to search I realized that it was not that simple. I saw that there are multiple different types of guns from all different time periods. I know the basics about guns but I do not know the details of their history.
Crime Scene Investigation For my assignment, I will be looking into the case of James Bulger, aged 2 years old, who was kidnapped and murdered by John Venables and Robert Thompson on February 12th 1993. Through evidence found at the crime scene and testimonial statements, the police saw that the two boys, ages 11, abducted James from Bootle Strand Shopping Center, Liverpool. They took him on a long, aimless walk where they brutally attacked him and left him for dead. In my assignment I will show how work done by the police, forensic scientists and Investigators helped to convict Jon and Robert.
There are several steps that need to be taken in order to process a crime scene. Some of the steps include: securing the scene, a detailed search, documenting the crime scene, collecting and preserving evidence, and finally releasing the scene. All of the following steps are crucial to avoid any possible contamination or otherwise compromise the scene before it can be released. Few, if any additional opportunities exist when processing a crime scene, so the first time is most pertinent.
I love guns. My dad has many guns and when I lived back in Florida I would go to the gun range

Unable to contain my excitement, my endless chatter fills the car on our short drive to our destination. Showing me the proper technique for shooting, my father effortlessly hits every clay disc thrown his way, which only makes my smile widen as I prepare to shoot. I hold my head high in the air and stride over the rocky canyon terrain to take the gun from my father’s hands, certain that I will impress him once again. As soon as my hands touch the cold firearm, though, my confidence disappears and is replaced by shaky breaths and trembling fingers. The gun feels far too heavy in my hands. Fear grabs hold of me as I looked down the barrel of the firearm, too scared to pull the trigger and disappoint my dad. Forcing myself to breathe slowly and deliberately, I take aim and
