These profiles fall between psychology and law enforcement, some call it “investigative psychology” while another refers to it as “crime action profiling”. The main connection, the common goal they all share; help investigators examine evidence, narrow down a suspect pool, or give helpful tips on how to interrogate a suspect already in custody. Psychology is used to investigate behavioral patterns, personality traits, and psychopathologies. Demographic variables including age, race, and geographical locations are also used in the profiles. Recently criminologists, law enforcement officials, and psychologists have all teamed together to take criminal profiling, which started out as an art and transform it into a reliable science.
DNA evidence is vital in helping the search for truth in many criminal cases such as a murder case, rape case or up any serious case. The offenders of these cases often committed because they do not want people to see their crime event’s doing. Some case against life, the offenders are a highly skilled and cover their actions by destroying evidence. In rape case, the rape scene or event which not only affects the body and mind of a rape victim, but also affect the confidence of the society toward with law enforcement. However, the evolution of scientific and DNA technological advances play a role in helping the criminal justice system.
DNA can be used as evidence to charge and imprison people. There are many pros to forensic dna like solving crimes and finding criminals. But Forensic dna also has many cons too like how dna can be tampered with and can falsely incriminate innocent people. Dna being used to throw the track off of criminals and nowadays be used to forge another person’s fingerprint on to a weapon of a sort and left behind to falsely accuse an innocent person so now Dna is not reliable all the time. Dna that has been planted onto a crime scene will incriminate innocent people and this will result in the falsely accusing/charging of innocent people for a sentence and charge they did not do and should not have to serve time for.
Racial Profiling is a criteria police departments use when finding suspects. In the article “Not Race Alone”it states, “ They are using crime data to identify possible suspects. Ethnicity is just one of many criteria they consider” (Dutta 1). This quotation explains that Police departments use racial profiling as a consideration. It is essential to use racial profiling when looking for possible suspects especially in the police department.
Abstract Research methods are procedures used for gathering information. The information observed is individual or aggregate data on a phenomenon. Traditionally, there are wide ranges of research methods in criminal justice. The most commonly used are survey methods and data analysis. According to Kleck et al; (2006) “survey research is the dominant method of collecting information followed by use of archived data.’’ Furthermore, the most important sources of crime information in U.S criminal justice system are the FBI’s Uniform Crime Reports (UCR) and the BJS’ National Crime Victimization Survey.
“While body camera evidence has already played a role in the disciplining of a few officers nationally, advocates are warning that the technology will not be a magic bullet for behavior or resolution of legal disputes.” Meanwhile the body-warn cameras are known for having evidentiary value. They are useful for resolution of citizen complaints and also yield evidence for criminal prosecution. Additionally body cameras are admirable for those who are training to be a police officer, so they could watch how police- citizens encounters. Although on the other hand this body worn camera can also have limitations for legal complications. “Officer Privacy is also an issue with cameras.
From there, they can be broken down into even more specific categories, however, each category will usually fall under organized or disorganized. Classifying serial killers can be useful for law enforcement because it helps them to determine common traits shared among different types of killers. When trying to apprehend a killer, once you determine what type they are, you can use
The media tends to focus on the mistakes of the criminal justice system. Many reports have highlighted the cases of wrongfully imprisoned people. While these cases are indeed wrong, many of the people imprisoned have committed a crime. For example, DNA evidence is now a useful determinant of guilt or innocence with regard to rape cases. Gwendolyn Carrol wrote an article for the Journal of Criminal Law & Criminology.
Eyewitness testimonies has contributed tremendously towards law enforcement and crime, helping to place the accused behind bars for the crimes they have committed. Although it has helped to place a huge number of these accused behind bars, eyewitness testimony has been proven to be rather inaccurate and unreliable (Brigham, Maass, Snyder, & Spaulding, 1982). Through the advancement of technology, DNA evidence has proven that some of these individuals have been wrongfully incarcerated. DNA evidence may be an effective measure, but it would only help to solve a minimal number of cases when DNA samples present. At times, DNA evidence might only help to prove that the individual is present at the crime scene.
Eyewitness identifications can ruin the lives of innocent people and cause them to live their life behind bars for a crime they didn’t commit. Eye witness testimonies can be the deciding factor for a criminal trial, but the the reliability of the eye witness testimonies is not always as accurate as we assume. Although eyewitness identifications can be very beneficial in solving a case, there have been countless instances where the eyewitness identification has been incorrect due to multiple psychological factors. Memory is the most important aspect to eyewitness identifications because it is the sole tool for remembering details of a specific event, but memory is very complex and has many different aspects that can cause for unreliable
