Criminals especially those who are going through court proceedings may not feel comfortable disclosing certain information to someone they know to be a researcher. Typically most researchers are similar to police in characteristics, white and middle class, so acting covertly will most likely increase comfortability between the researcher and criminals, allowing more valid research to be acquired. Similarly judges and police may alter their behaviours if they know the researchers true identity in a bid to disguise any flaws in their practices and unjustified law enforcing. However, Positivists would argue that data collected by covert observations aren’t at all valid, they are biased as they are based off of the observer’s interpretations. This could be especially true in the case of researching court proceedings as it is unlikely many researchers have gone through one themselves.
In line with this, the investigative department requests warrants to search for evidence, but they must be approved by the judicial branch. (Lynch, 1998) Most defenses that invoke the exclusionary rule are based on the lack of or improper application of search warrants. Those that support the continued use of the exclusionary rule argue that there must be this line between the police officers that are often emotionally involved in a case, and an impartial third party that can objectively review the evidence. Without this safeguard, citizens would have little protection from overzealous police officers who could search their homes and persons with almost anything serving as probable cause in their opinion. The fact that officers know that illegally obtained (but true) evidence will quite possibly be thrown out, and therefore dangerous criminals will be freed, will encourage them to follow the proper procedures.
We must be sure that finding those answers are done ethically from the crime scene to trial. The Investigator Ethical Considerations From the moment the investigator gets a case professionalism, knowledge of laws and procedure is what has to be followed. If at any time the investigator became biased and used emotion instead of just facts of the case could be compromised. Remaining unbiased in either homicide or rape can be extremely difficult for even the most ethical investigators. Handling evidence properly is one of the most crucial points of any investigation.
When taking notes officers must learn to keep it short and abbreviated, and at the same time understandable for not only you to read, but if you become ill, injured or deceased, others must be able to read and understand your notes. Taking notes is an acquired skill, while taking notes you do not include words such as a, and or the. In addition, a good note taker never carries a spiral notebook to put your notes in, because this notebook most likely has the amount of pages written on the front cover and any missing pages could be evidence that something has been removed. In addition to note taking, I also would like to discuss digital versus film photography in an investigation. From my own experience I prefer digital over film photography, mainly because once you get the film developed in a
Questioned document examiners also determine if the documents are forgeries, and they analyze paper, ink, and writing instruments for possible evidence. Education, experience, and licensing requirements for forensic technicians and forensic scientists vary greatly depending on the exact position. Entry-level technicians should
Next in computer forensics investigation is the importance of preservation of evidence is also an important task. Any tampering and manhandling of the evidence need be prevented. Collection of the evidence and even duplicating the digital evidence is also an important part of ethical conduct. As a computer forensics investigator there are some ethical values such as integrity, accuracy and authenticity should be exercised in an ethical environment. The evidence that is produced before any court should be fairly examined and analyzed.
Forensic Technician Duties In many policies departments throughout the United States and the rest of the world, the forensic technician is a sworn peace officer or case investigator who responds to and processes crime scenes. A forensic technician has many different job duties. Their job duties include responding to crime scenes, to document the scene as well as identify, collect, preserve, and transport evidence to a crime lab. A forensic technician may have to perform tests on weapons or substances, such as fiber, hair, and tissue to determine significance to investigation and they may have to testify as expert witnesses on evidence or crime laboratory techniques. The technician collects physical evidence such as bullet casings, footprints, hairs, guns, fibers, fingerprints, DNA and clothing fibers.
The purpose also is if law enforcement was to take the evidence it would not be used in the court of law unless issue or that person can be set free of all charges. Basically one wrong moved can make us lose a suspect of a horrible crime if we are not careful. Law enforcement just need to be cautious so they are doing their jobs correct, and setting a person free will get them into trouble (cjlf.org, 2011). When we are identifying the exclusionary rule it is a great rule to have so police have to stop and think. Police have to think before they search because it could cost them a lot if they just do what they want.
Research Process and Terminology Paper Rachael Gammill CJA 433/Research Methods in Criminal Justice October 3, 2011 Michael Walker Research Process and Terminology Paper Terminology and the Criminal Justice System hold a key to the basic understanding of concepts and prosecution of words. What this means is simply put to be able to transcribe knowledge with his or her words to the case at hand can make the difference whether the case is won or lost. Without being able to translate in the proper terminology the point taken can be lost in a simple mathematical formula given the Hypothesis based on the Criminal Justice System. The Hypothesis will be analyzed throughout the text and will be visited from a statistical point of view in how it determines how a case is handled. Including new terminology learned from the readings begins with the basics from the chapter discussions.
Faced with powerful incriminating evidence, defendants are often persuaded to change their plea or else mount a legal challenge to the admissibility of DNA profiling. This paper will firstly outline the procedures used in DNA profiling, without dwelling too much on the technical details. The basis of the technology can be described simply, and is not in dispute (see, for example, the decisions in People v. Castro, 545 N.Y.S. 2d, Supreme Court of New York, Bronx, 1989; R v. Lucas (1992) 2 V.R. 109).
