Current concerns in forensic science include the need for increased reliability and … becomes one of the most important issues in criminal justice.
Scientific Methods in Forensic Science
Forensic scientific methods are varied and complex,“ranging from dna analysis to chemical composition to pattern recognition,” (Bell, Sah, Albright, et al., 2018, p. 4541). Big data has also contributed tremendously to the … but lack the competencies required to effectively evaluate criteria for establishing instrument and method reliability and validity. The use of junk science in forensics can, and most likely has, led to miscarriages of justice. Even the peer-reviewed process has proven flawed given the lack of substantial definitions ……

Scientific Method Applied To Forensic Science Paper
...Forensics dna The Role of Forensic Science in Crime Scene Investigation
The scientific method begins with the identification of a problem. Questions are asked, data is collected, a hypothesis is formed and then tested. The scientific method is essentially no different from the kind of investigative work that investigators of a crime scene do on a daily basis. They a faced with a problem: a crime has occurred. The questions they must ask are: what happened, why, when, who was involved, where did it occur, and how did it happen? They collect data and using forensic science to analyze the data, they come up with a narrative that answers those questions (Shaler, 2011). Lab work helps to verify the story by providing more evidence that can give more details. This paper will show how the scientific method is applied to forensic science.
The forensic scientific method consists of five steps:

Crime Scene Management
...Forensics dna The Importance of Effective Crime Scene Management
The purpose of this paper is to provide a review of the relevant literature to explain the importance of securing crime scenes in order to protect evidence from contamination and preserve it for use by the courts. In addition, a discussion concerning different methods that might be necessary to document evidence at a crime scene and different collection methods that might be used at a crime scene is followed by an explanation concerning the chain of custody and why it is important. Finally, the repercussions of failing to protect evidence or establish chain of custody is followed by an explanation concerning how an investigator or forensic expert differentiates between what is or is not evidence. A summary of the research and key findings concerning the foregoing issues are presented in the paper’s conclusion.

Criminal Profiling Of Serial Killers
...Forensics dna Does Criminal Profiling Work or is it Unjustified The Case of Tim Masters
Introduction
Criminal profiling allows law enforcement to develop their understanding of particular types of crime, criminals, criminal behaviors, and crime-ridden areas. The FBI’s Uniform Crime Reporting (UCR) Program is one data set tool used in criminal profiling (FBI, 2019). However, criminal profiling is not an exact science but rather more of an art and there is a high degree of subjectivity that goes into creating a criminal profile. Thus, when it comes to the criminal profiling of serial killers, there are many factors that must be considered—biological, sociological, environmental, criminological, and psychological inputs. This paper will describe what is involved in the criminal profiling of serial killers, how the process works, who conducts it, what traits of serial killers profiles tend to focus on, and how effective the process is at helping law enforcement agents catch killers.……

Stephen Kings The Outsider Persuasive Argument
...Forensics dna Stephen King’s The Outsider: A Persuasive Argument
Introduction
The Outsider is a well-written book with exiting and unexpected turns and twists. The book has several well-developed themes. In my opinion, however, the central theme of the story is the rational man’s inability to believe that which does not conform to reality – the inability to believe in the supernatural. It is important to note that one of the most celebrated traits of the modern man is rationality. In basic terms, rationality could be conceptualized as the ability to rely on logic or reason in decision making. This effectively means that from a rational perspective, anything that does not conform to reason and logic cannot be accepted. We all start off in life having outrageous beliefs and fantasies. For instance, as kids we believe in the tooth-fairy and regard Father Christmas as a real benevolent person. These are beliefs we outgrow……
