...Criminal Identification Procedures in the 21st Century Within the criminal justice system many technological advances exist to assist law enforcement officials in identifying a criminal suspect. The technological advances that continue to assist the criminal justice system in these identifications are Deoxyribonucleic Acid (DNA) analysis, biometric identification, Intra-agency databases for DNA, fingerprinting and palm printing, and camera and wiretap surveillance. Each aspect serves a specific purpose in making certain that the right person is properly identified for the crimes that they commit. Each technological aspect makes certain that the criminal justice system can prove without a doubt that the person under arrest is the person responsible for committing the crime. Criminal Identification Procedures Deoxyribonucleic Acid (DNA) analysis is an examination method that allows any organism to be identified, by its genetic sequences. DNA analysis is highly accurate, important, and used all across the world for important reasons. The main purpose for DNA analysis is identifying individuals who are suspects in criminal cases, identifying victims or their remains when other means of identity is not possible. The advantages of DNA analysis are reliable, accurate results, and helps solving old and new cases. The disadvantage of DNA analysis is it reveals information on physical state, this information is sensitive and must be guarded. Biometric Identification is a system based...

...Contemporary Hate Crimes, Law Enforcement, and the Legacy of Racial Violence Ryan D. King University at Albany-SUNY Robert D. Baller University of Iowa This article investigates the association between past lynchings (1882 to 1930) and contemporary law enforcement responses to hate crimes in the United States. While prior research indicates a positive correlation between past levels of lynching and current social control practices against minority groups, we posit an inverse relationship for facets of social control that are protective of minorities. Specifically, we hypothesize that contemporary hate crime policing and prosecution will be less vigorous where lynching was more prevalent prior to 1930. Analyses show that levels of past lynching are associated with three outcome variables germane to hate crime policing and prosecution, but the effect of lynching is partly contingent on the presence of a minority group threat. That is, past lynching combined with a sizeable black population largely suppresses (1) police compliance with federal hate crime law, (2) police reports of hate crimes that target blacks, and in some analyses (3) the likelihood of prosecuting a hate crime case. Our findings have implications for research on law and intergroup conflict, historical continuity in the exercise of state social control, and theories that emphasize minority group threat. Steven F. Messner University at Albany-SUNY onflict theories of crime and criminal law posit that the state...

...Casey Anthony Case Dixit and Gothwal (2015) define criminal law as a rule that control the social conduct and prohibits the acts that are harmful to the people and as such, threatening the safety and the welfare of societal members. Morse (2015) contends that criminal laws define the punishment levelled on the people who break the prescribed societal conduct while Holland (2015) asserts that criminal laws refer to the state laws, which make certain actions illegal and punishable by fines or imprisonment. Accordingly, the case of Casey Anthony falls under the criminal and as such, the forensic evidence gathered from the trunk of her car makes her criminally reliable, as the said evidence is admissible in the court of law. The forensic experts from the Federal Bureau of Investigation (FBI) examined a band of hair recovered from her vehicle, which exposed evidence of apparent decomposition. Forensic analysis of the recovered band of hair showed consistence with the band of hair of the deceased. The FBI experts who conducted forensic analysis on the band of hair told the court that the sample had many consistencies in relation to the post-mortem banding. Moreover, microscopic hair examination specialist told the jurors that the root portion of the air was dark and, therefore, consistent with the evidence presented by the FBI. The analyzed evidence showed that the hair was evicted forcibly from the deceased. Further, an investigator of the crime scene testified that that there...

...The comprehensive roles of crime and intelligence analysis they relate to the future of policing and homeland security. The role of the criminal intelligence analyst is to help predict and prevent crimes and also monitor ongoing criminal activity. Analysts do this by gathering information from surveillance, databases, technology (such as GIS geographic information systems), informants, financial records, telephone and other communication records and public information sources. A criminal intelligence analyst takes all of this information, evaluates it, verifies its accuracy and transforms it into viable intelligence to assist law enforcement officers in preventing crime, making arrests or gathering essential evidence for prosecution down the road. Law enforcement intelligence analysts must be capable of finding relationships among the information they are analyzing; at the same time they must understand the criminal mind to create suspect profiles and also discover connections between several suspects. Thus criminal intelligence analysts must have logical, technical, investigative and criminology skills. Intelligence analysts assist with a variety of cases included those related to terrorism, weapons of mass destruction, auto theft rings, narcotics, gangs, money laundering, child pornography rings and other organized crimes, as well as homicides, sexual assaults, burglaries, and so forth. Criminal intelligence, as a process, offers the law enforcement a coherent, rational,...

...fundamental component of the justice system. Forensic scientists use scientific techniques and knowledge to assist law enforcement in investigations and solving crimes. They collect and analyze numerous types of evidence, including blood, body fluids; DNA; and human tissue. Forensic scientists assist the decision makers by showing the prosecutor if the issue has merit before it reaches the courtroom thereby reducing the number of cases having to be heard. Their decisions are based on scientific investigations and not circumstantial evidence or unreliable witnesses. Forensic scientists can restore faith in the judicial system with the use of science and technology for facts in criminal and civil investigations. The legal system is established on the belief that the legal process results in justice for all. History of forensic science The history of Forensic science or the applying of scientific principles to legal questions has a lengthy and interesting history. The first recorded autopsy was reported in 44 B.C was on Julius Caesar, where the Roman physician, Antistius proclaimed that he had 23 wounds on his body but only one was fatal. In 1248, a Chinese book entitled “His Duan Yu” (meaning The Washing Away of Wrongs) explaining how to tell apart a drowning from a strangulation. This was also the first recorded use of medicine to assist in solving crimes. In 1590, the first microscope was developed. In 1775, Karl Wilhelm Scheele first discovered forensic detection...

The procedures allow the investigators to solve the crime efficiently as well as deterring future crimes. Present day crimes just as human nature are complex. The extent of sophistication of how crimes remains committed and the challenges associated with criminal laws have placed a significant burden, on people choosing a career in criminal investigation and prosecution of criminals, within the system of criminal justice. Most concerns while conducting a criminal investigation has always been on the legality of when and how to conduct the exercise. Physical evidence collection, witness interviewing and assorted surveillance used in the investigation, all fall under a keenly watched category in the investigative process, not all investigations ends correctly; however, the ultimate goal of an investigative process depends on the process undertaken. For this reason, investigative process should follow a predefined pattern. This calls for frequent simulation exercise undertaken by investigators to keep them in check with the predefined patterns of investigation. This paper seeks to give responses to some of the questions posed in a simulation exercise aimed at standardizing a criminal investigation involving multiple explosions traversing two states.

...Introduction The production of physical evidence is essential for the conduct of criminal trials. Chain of custody procedures represent the application of a legal principle intended to ensure the evidence produced at trial is the same evidence seized by law enforcement authorities related to the crime, and has not been confused with evidence related to other crimes. In addition, chain of custody procedures are necessary to ensure the evidence has not been altered or tampered with between the time of seizure and the time the evidence is produced in court. Both documentation about the way the evidence was protected as well as the legal adequacy of the procedures used by law enforcement authorities is necessary to establish chain of custody. The failure to establish a chain of custody may result in the exclusion of the evidence at trial, although in some situations involving a broken chain of custody the evidence may be admissible if it can be precisely identified by a unique characteristic such as a serial number. While the documentary requirements to establish chain of custody are relatively similar for the evidence for most crimes, there is variation in the procedures used to maintain a chain of custody depending on the type of crime and the nature of the evidence. The burden of establishing the authenticity of the evidence with chain of custody generally rests with the party seeking admission of the evidence at trial, although there may be a presumption of the integrity of the evidence...
