COMPARATIVE CRIMINOLOGY AND C.J. SYSTEMS

Criminology is the scientific study of the causes and prevention of criminal behavior, informed by normative, legal and philosophical perspectives on scientifically established facts. In 1924, Edwin Sutherland defined Criminology as “the body of knowledge regarding crime as a social phenomenon that includes within its scope the process of making laws, of breaking laws, and of reacting toward the breaking of laws.” Criminologists are drawn from a wide range of disciplines including economics, history, law, psychiatry, psychology, political science, and sociology. Criminology is the study of crimes, criminals, crime victims, theories explaining illegal deviant behavior, the social reaction to crime, the effectiveness of anti-crime policies and the broader political terrain of social control. Criminology involves research to discover what really happens in the streets, in police stations and courts, behind prison bars, in board rooms, and on battlefields. Its practitioners are likely to engage in the systematic evaluation of the effectiveness of criminal justice policies and proposals, as well as the discovery of the socio-cultural, economic and global roots of crime, rates of crime and meaning of crime, or the diverse ways of measuring criminal activity and its impact. Criminologists typically collect and analyze data sets that may be quantitative, for example statistical studies on the rise and fall of crime rates, and/or qualitative, for example ethnographic studies on street subcultures and drug use.

The criminal justice main systems are: State: State criminal justice systems handle crimes committed within their state boundaries. Federal: The federal criminal justice system handles crimes committed on federal property or in more than one state. Law Enforcement: Law enforcement officers take reports for crimes that happen in their areas. Prosecution: Prosecutors are lawyers who represent the state or federal government

    Our criminal justice system [The aggregate of all operating and administrative or technical support agencies that perform criminal justice functions. The basic divisions of the operational aspects of criminal justice are law enforcement, courts, and corrections] consists of three component agencies. The police, the courts, and the corrections system all work together to ensure that justice is carried out. None of these three components operates independently of the others. If someone is arrested by the police, their guilt or innocence is determined by the courts, and any potential punishment after conviction is handled by the corrections system.…

    The criminal justice system is nothing more than different sets of agencies tasked to carry out penalties for those who have committed a crime and broken the law. How the criminal justice system actually works depends on where and who is in charge such as, a city, county, federal government and also where the laws are effective such as, military jurisdiction. The main two systems that make up the criminal justice system are State and Federal systems. State criminal justice systems handle only crimes committed within the state that they are in charge of.

    Criminology & Penology is the branch of social science that deals with occurrences of crime, their causes and their consequences. It is the study of crime within society. In society an activity that occurs outside the boundaries of the law, is considered to be a crime. “Crime” in society varies by perspective. For example, German criminologists might look at an abortion as a criminal offence, whereas Chinese criminologists look at abortions as conform behavior. Whether a society looks at an activity as a crime or not, depends on it’s laws, and values. “Since "crime" is a matter of judgment, it is necessary that analysis is concerned with the interpretations and definitions of situations and actions. This analysis is not possible with quantitative methods. The inquiry of "crime" is inseparably tied to the analysis of social control through (mainly) criminal law and its institutionalized practices (police, public prosecution, court, prison etc.) of segmentation, typifying, classification and judgment. "Crime" is constituted through the definitions of situations that are negotiated between different parties (offender, victim, witness, policeman, judge etc.) in processes of social interaction. These definitions determine if an incident is noticed, if it is registered as a case, and if the case is classified as "criminal" on its way through the criminal justice institutions.”(http://www.qualitativeresearch.net/index.php/fqs/article/ view/1119/2484)…
