Crime Scene Investigation or CSI has become a very popular topic thanks to the many movies or TV show in this subject. This is commonly known as the CSI Effect where people lost touch of the real work of CSI agents. In the TV show cases are usually solved in matter of hours to maybe days when in reality it can take months or years to solve a case. The main objectives of any crime scene investigator are to recognize, preserve, collect, interpret and reconstruct all the relevant physical evidence at a crime scene. This evidence is send to forensic laboratories to be examined and provide the investigator with information that may help solve the case. Later on this information can be used in court, for this reason it is critical that the investigator gather the evidence properly and legally.
Most police investigations begin at the scene of a crime with the first responders to the crime scene usually police officers, fire department personnel or the emergency medical personnel. Their actions of the first responders to the crime scene can help the investigation or can severely damage it. The first responder has to secure the area, assist any victim if any, arrest the suspects if any, detain all witnesses, protect the crime scene and provide information about all the movements or alteration made to the crime scene investigators or their supervisor. The crime scene should be secured by an officer designated to be the security officer. His or her duty is to be responsible for preventing unauthorized individual from entering the crime scene and to keep a record of all the personnel that enters or exits the crime scene. In addition to this there should be some kind of barrier such as rope, or yellow tape to let people know that an investiga...

... not unusual for CSI agent or police officer to work overtime. This show may have a lot of the fantasy of Hollywood about CSI agents, but they show some truth. The work of an investigator should be done correctly and legally. Following all the step necessaries to collect evidence and used their experience and expertise to solve the case. Investigators need to be open mind individual well prepare and objective. Their only task should be the proper gathering of all the relevant information or facts at a crime scene. This line of work is not easy and not everyone can do it. Investigator will see what a man is cable to do to another man, from rapes to murders, suicides, work accident and many more gruesome scenes. This can have a profound in pact in the investigator so they must be ready physically and mentally to face the challenges of being a criminal investigator.
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.
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).
Rape, murder, theft, and other crimes almost always leave a devastating mark on the victim. More often than not, it would be impossible to identify the perpetrator a crime without forensic science and the technology it uses. Forensic science allows investigators to unmask the secrets of the crime scene. Evidence gathered at the crime scene helps to identify the guilty party, murder weapon, and even the identity of the victim (Harkawy, 1991: 276). The new technologies enables the forensic experts to have better and faster access to accumulated information, to be more accurate in the identification of victims or delinquents, and minimizes the possibility of wrongful accusations. New technology has improved the methods and techniques that forensic scientists and law enforcement investigators use, in order to provide a safer environment for other people. Information technology is one of the most important aspects in forensic science. It is very important for the forensic experts to receive the undisturbed evidence, such as fingerprints left at the crime scene, as quickly as possible, for more accurate readings. Thus using space technology, such as satellite communication, enables the forensic experts to "gather and digitize evidence at the crime scene, enter it into an on-site computer, and beam the data to a crime lab for swift analysis" (Paula, 1998: 12). Therefore, due to the use of this technology, forensic experts in laboratories can examine the evidence in short time, and the possibility of damage or unlawful manipulation of the evidence before the trial is minimal (Paula, 1998: 12). More often than not, "criminals" wear gloves at the time of the crime, thus to obtain a fingerprint...
In the CSI field, CSI workers must be very accurate about details and properly collect different forms of data and evidence (Crime 1). CSI workers must be able to write forms
Mass media often times portrays a negative impact on police officer. There are few individuals who gives negative impression towards cops but will call upon these officers once it suitable for their needs. The primary role of a police officer is to protect and serve. Before one should critique about a police officer, especially the way in which society view’s a officer, it is significant to understand the role, responsibilities, and different types of officers as well as Detective. (DA). In a simple definition police officers protect lives and property while a detective gather facts and collect evidence of possible crime. “Police Officer or Detectives”.
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.
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.
The job of Criminal Investigator has varying working conditions. Some days require long shifts that can fall on weekends, during the day, at night, even on holidays (“Become a Criminal Investigator”). In some cases a Criminal Investigator can be on call twenty four hours a day (“Crime Scene Investigator”). There are also days spent strictly in the lab running numerous tests and experiments. The days spent in the lab require patience because most of the testing and e...
Times have changed; crime has evolved into a multifaceted issue with deep seeded roots. Today, law enforcement officers have additional responsibilities with greater expectations. It is no longer just about bravery, but about the ability to make complex, legal decisions in the midst of danger and chaos. Officers are now required to complete many hours of training regarding detention, arrest, search and seizure, emergency vehicle operations and defensive tactics. Officers are trained to investigate incidents involving domestic violence, sex offenses and crimes against children.

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
investigators take from the crime scene. With scientific methods it helps investigators to produce a
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
Forensic science has paved the way to a new world of technological advancements in solving crime, through DNA analysis, new technology such as M-Vac, improving systems such as CODIS and other investigative methods. As forensic science technology advances, the chance of an individual being able to commit a crime and walk away free without leaving any trace of evidence will lessen. While forensic science has its limitations, it can be the only way to provide an accurate account of what actually occurred at some crime scenes.
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice
