The skills that investigators require can be categorized as follows: 6.1. Technology skills: The techniques used to solve a crime range from the very complex to very simple. Knowledge about computers and related technologies is an absolute must in today’s electronic era. For e.g. an examination of digital media can reveal internet activity, journals, videos or audio recordings. Sometimes there are hidden or deleted files. There are sophisticated technologies available to improve the quality of audio and video recordings if they are not clear and access the hidden/deleted files. These electronic communications (such as e-mails and picture messaging) may be accessible from Internet service providers, cellular service providers and from computers used by …show more content…
DNA analysis is also now regularly conducted and may lead to a single source profile or a mixture. The latter may not be as desirable as the former as the probative value of the profile is very less. Similarly there are sophisticated technologies for analyzing other biological evidence such as blood, semen, bone/tissue, saliva urine, hair and fingernails. Automated ballistics technology too has become mainstream and cases that were earlier thought to be unsolvable can now to be solved. The above are only very few technologies that are commonly used in crime scene investigation. Similarly there are technologies for photographing the scene, collecting evidence and recording evidence. Knowledge about all these technologies would help in crime scene investigation though only experts would have specialized knowledge in a particular field. 6.2. People skills: People are the focus in any criminal investigation. Having good communication skills, patience, empathy, active listening skills, good judgment and problem solving skills, persuasive skills, negotiation skills, leadership skills, presentation skills and motivational
Comparing simple techniques simply to retrieve a piece of evidence is completely different as we learn more about the science and learn from the mistakes made in the past. Looking back at the 1800’s and comparing the technology of the 21st century, the difference is certainly huge. The increase in technology makes information more vast and more ideas can be shared easily. Many sciences are based off many “what ifs” while forensic science is more factual and attempt to solve puzzling occurrences and events and get down to what truly
So how did crime get solved without the modern use of technology? According to Fisher (2000), investigations were much more difficult and time consuming, and technology that was available at time did little to help. For example, investigators used Polaroid pictures to get crime scene shots. A few years later, as technology advanced, investigators started collecting evidence with camcorders, which were much lighter and recorded in color, but still very large.
Being a CSI agent offers tons of exciting action with interesting daily tasks, mental challenges, and modest educational requirements compared to most occupations. CSI agents experience many interesting daily tasks, they first walk through the crime scene to determine what evidence is available and collect it. According to Chron, DNA experts use bodily fluids and substances to identify criminal subjects even in cases that are very old. Using small details such as fibers, hair, paint, glass, pollen and food residue, that discovers case specifics. This shows that CSI can uncover things with the smallest pieces of evidence to catch suspects.
Despite the television show's portrayal of trace evidence and other physical evidence being left behind at every crime scene, this is not the case in every criminal investigation. In fact, many criminal investigations yield no evidence that can be forensically tested. This means the investigator must gather information from the crime scene such as witness statements, victim statements, possible suspects including those who are seen fleeing, as well as any physical evidence. The investigator must also follow any leads gathered from victim and witness statements. While in CSI the investigator always catches the criminal within an hour, a criminal investigation may take days, weeks, months and even years before being solved.
This includes finding evidence of criminal activity and regaining data from computer hard drives, even those that have been damaged or deleted. They analyze this data for clues and evidence, and may trace hacks or gauge the effects of malware on an information system. For many employers, applicants must have a bachelor’s degree in computer information systems or computer science. Some also require skills gained from an advanced degree program. Examples of some skills include a firm working knowledge of various operating and network systems, data retrieval procedures, and the ability to provide IT
The detective might take a course or two, attend a seminar hosted by law enforcement or gain more knowledge through a mentor. (-- removed HTML --) Employment (-- removed HTML
In King, Justice Kennedy referred to the invention of DNA technology as “one of the most significant scientific advancements of our era.” This statement has been criticized, but the impact of DNA technology has been significant. Currently, forensic analysts can use “junk” DNA to identify a person with near certainty. Law enforcement can collect a person’s DNA through saliva. The sample is then uploaded to CODIS, a national network of DNA databases.
Technology and Communication systems are critical tools in policing. The rate of technological change in recent years is so fast that I personally believe that is safe to predict that in a mere few years from now, current technology will be substantially improved if not obsolete. Technology is constantly changing the way police departments operate in many ways. When I first started in EMS 20 years ago, I had intended to use dispatching as a gateway into policing (instead of Emergency Medicine.) Back then, Computer Aided Dispatching was ground breaking technology, GPS did not exist, tracking of units was done with paper, graphs, whiteboards and bulletin boards.
For example the new version of TVs can sign in the web store images etc. for this we can understand that a TV nowadays it can be used for digital evidence. The most
Forensic science has been an aid to the law enforcement community for years now. It has solved cases that were unsolved years before DNA and science started to play a role with cases and law enforcement. The case of Samuel Reeves and James Layne was unsolved in the year 1989, this was considered a cold case because it had been years since they found who the murderer was. This case was considered a crime of passion, where it first started off by kissing and having the same attraction towards each other, but when James Layne started to get aggressive and not respecting Reeves decision to not have sex, that was when things got hectic. Forensic science helped this case by the use of fingerprints, they found the fingerprints in a bottle, and when
A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
Problem-oriented policing, also known as operational strategies, have five core elements: preventive patrol, routine incident response, emergency response, criminal investigation, and problem solving. In addition to the five core strategies, there is also a lone ancillary operation strategy, support services. Law enforcement officers use this to help prevent crime by being pro-active and responding to calls. The first of the core operational strategies is the prevention patrol. Prevention patrol is an active response and most dominate operation of police strategy.

The goal of the computer forensics is to provide information about how the crime happened, why and who is involved in the crime in any legal proceeding by using the computer forensic tools.
I feel that DNA is the only reliable forensic tool because its principles are example of real science. Mentioned in the video, forensic science was developed by law enforcement, but DNA analysis was developed by medical science. A much more reliable source. There may be certain situations where DNA isn’t the best tool to go off of. Like for example if there isn’t an enough quantity of it at the scene of a crime or if it has been mixed with someone else’s (Kaye and Sensabaugh, 2000).
Crime scene photography, sometimes referred to as forensic photography or forensic imaging, is the art of producing an accurate representation of an accident or crime scene. Crime scene photography is an important asset in the collection of evidence at the crime scene, documents the appearance and location of victims, shell casings, footprints, bloodstain patterns, and other physical evidence. In order for photographs to be admissible in a court of law, the standard for photographs of crime scenes and evidence must be of sufficient quality. Photography has a vital role in the decision made in court because the pictures are to represent the scene as it was exactly. Digital SLR single reflex camera is the most often used camera in crime scene investigations.
