In criminology, the broken windows theory states that visible signs of crime, anti-social behavior and civil disorder create an urban environment that encourages further crime and disorder, including serious crimes. The theory suggests that policing methods that target minor crimes such as vandalism, loitering, public drinking, jaywalking, and fare evasion help to create an atmosphere of order and lawfulness.
Juvenile delinquency, also known as juvenile offending, is the act of participating in unlawful behavior as a minor or individual younger than the statutory age of majority. In the United States of America, a juvenile delinquent is a person who commits a crime and is under a specific age. Most states specify a juvenile delinquent as an individual under 18 years of age while a few states have set the maximum age slightly different. In 2021, Michigan, New York, and Vermont raised the maximum age to under 19, and Vermont law was updated again in 2022 to include individuals under the age of 20. Only three states, Georgia, Texas, and Wisconsin still appropriate the age of a juvenile delinquent as someone under the age of 17. While the maximum age in some US states has increased, Japan has lowered the juvenile delinquent age from under 20 to under 18. This change occurred on April 1, 2022 when the Japanese Diet activated a law lowering the age of minor status in the country. Just as there are differences in the maximum age of a juvenile delinquent, the minimum age for a child to be considered capable of delinquency or the age of criminal responsibility varies considerably between the states. Some states that impose a minimum age have made recent amendments to raise the minimum age, but most states remain ambiguous on the minimum age for a child to be determined a juvenile delinquent. In 2021, North Carolina changed the minimum age from 6 years old to 10 years old while Connecticut moved from 7 to 10 and New York made an adjustment from 7 to 12. In some states the minimum age depends on the seriousness of the crime committed. Juvenile delinquents or juvenile offenders commit crimes ranging from status offenses such as, truancy, violating a curfew or underage drinking and smoking to more serious offenses categorized as property crimes, violent crimes, sexual offenses, and cybercrimes.
Geographic profiling is a criminal investigative methodology that analyzes the locations of a connected series of crimes to determine the most probable area of offender residence. By incorporating both qualitative and quantitative methods, it assists in understanding spatial behaviour of an offender and focusing the investigation to a smaller area of the community. Typically used in cases of serial murder or rape, the technique helps police detectives prioritize information in large-scale major crime investigations that often involve hundreds or thousands of suspects and tips.
Problem-oriented policing (POP), coined by University of Wisconsin–Madison professor Herman Goldstein, is a policing strategy that involves the identification and analysis of specific crime and disorder problems, in order to develop effective response strategies. POP requires police to identify and target underlying problems that can lead to crime. Goldstein suggested it as an improvement on the reactive, incident-driven “standard model of policing”.
Crime prevention through environmental design (CPTED) is an agenda for manipulating the built environment to create safer neighborhoods.
Environmental criminology focuses on criminal patterns within particular built environments and analyzes the impacts of these external variables on people's cognitive behavior. It forms a part of criminology's Positivist School in that it applies the scientific method to examine the society that causes crime.
Right realism, in criminology, also known as New Right Realism, Neo-Classicism, Neo-Positivism, or Neo-Conservatism, is the ideological polar opposite of left realism. It considers the phenomenon of crime from the perspective of political conservatism and asserts that it takes a more realistic view of the causes of crime and deviance, and identifies the best mechanisms for its control. Unlike the other schools of criminology, there is less emphasis on developing theories of causality in relation to crime and deviance. The school employs a rationalist, direct and scientific approach to policy-making for the prevention and control of crime. Some politicians who ascribe to the perspective may address aspects of crime policy in ideological terms by referring to freedom, justice, and responsibility. For example, they may be asserting that individual freedom should only be limited by a duty not to use force against others. This, however, does not reflect the genuine quality in the theoretical and academic work and the real contribution made to the nature of criminal behaviour by criminologists of the school.
In criminology, rational choice theory adopts a utilitarian belief that humans are reasoning actors who weigh means and ends, costs and benefits, in order to make a rational choice. This method was designed by Cornish and Clarke to assist in thinking about situational crime prevention.
Crime prevention is the attempt to reduce and deter crime and criminals. It is applied specifically to efforts made by governments to reduce crime, enforce the law, and maintain criminal justice.
David M. Kennedy is a criminologist, professor, action researcher, and author specializing in crime prevention among inner city gangs, especially in the prevention of violent acts among street gangs. Kennedy developed the Operation Ceasefire group violence intervention in Boston in the 1990s and the High Point Model drug market intervention in High Point, North Carolina, in 2003, which have proven to reduce violence and eliminate overt drug markets in jurisdictions around the United States. He founded the National Network for Safe Communities in 2009 to support cities using these and related strategies.
Criminology is the study of crime and deviant behaviour. Criminology is an interdisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, as well as scholars of law.
David L. Weisburd, is an Israeli/American criminologist who is well known for his research on crime and place, policing and white collar crime. Weisburd was the 2010 recipient of the prestigious Stockholm Prize in Criminology, and was recently awarded the Israel Prize in Social Work and Criminological Research, considered the state's highest honor. Weisburd holds joint tenured appointments as Distinguished Professor of Criminology, Law and Society at George Mason University. and Walter E. Meyer Professor of Law and Criminal Justice in the Institute of Criminology of the Hebrew University Faculty of Law, At George Mason University Weisburd was founder of the Center for Evidence-Based Crime Policy and is now its executive director. Weisburd also serves as Chief Science Advisor at the National Police Foundation in Washington, D.C., and chair of its Research Advisory Committee. Weisburd was the founding editor of the Journal of Experimental Criminology, and is now the general editor of the Journal of Quantitative Criminology.
Alcohol-related crime refers to criminal activities that involve alcohol use as well as violations of regulations covering the sale or use of alcohol; in other words, activities violating the alcohol laws. Underage drinking and drunk driving are the most prevalent alcohol‐specific offenses in the United States and a major problem in many, if not most, countries worldwide. Similarly, arrests for alcohol-related crimes constitute a high proportion of all arrests made by police in the U.S. and elsewhere.
Crime hotspots are areas that have high crime intensity. These are usually visualized using a map. They are developed for researchers and analysts to examine geographic areas in relation to crime. Researchers and theorists examine the occurrence of hotspots in certain areas and why they happen, and analysts examine the techniques used to perform the research. Developing maps that contain hotspots are becoming a critical and influential tool for policing; they help develop knowledge and understanding of different areas in a city and possibly why crime occurs there.
Crime displacement is the relocation of crime as a result of police crime-prevention efforts. Crime displacement has been linked to problem-oriented policing, but it may occur at other levels and for other reasons. Community-development efforts may be a reason why criminals move to other areas for their criminal activity. The idea behind displacement is that when motivated criminal offenders are deterred, they will commit crimes elsewhere. Geographic police initiatives include assigning police officers to specific districts so they become familiar with residents and their problems, creating a bond between law-enforcement agencies and the community. These initiatives complement crime displacement, and are a form of crime prevention. Experts in the area of crime displacement include Kate Bowers, Rob T. Guerette, and John E. Eck.
Crime opportunity theory suggests that offenders make rational choices and thus choose targets that offer a high reward with little effort and risk. The occurrence of a crime depends on two things: the presence of at least one motivated offender who is ready and willing to engage in a crime, and the conditions of the environment in which that offender is situated, to wit, opportunities for crime. All crimes require opportunity but not every opportunity is followed by crime. Similarly, a motivated offender is necessary for the commission of a crime but not sufficient. A large part of this theory focuses on how variations in lifestyle or routine activities affect the opportunities for crime.
A Crime concentration is a spatial area to which high levels of crime incidents are attributed. A crime concentration can be the result of homogeneous or heterogeneous crime incidents. Hotspots are the result of various crimes occurring in relative proximity to each other within predefined human geopolitical or social boundaries. Crime concentrations are smaller units or set of crime targets within a hotspot. A single or a conjunction of crime concentrations within a study area can make up a crime hotspot.
Crime pattern theory is a way of explaining why people commit crimes in certain areas.
Incarceration prevention refers to a variety of methods aimed at reducing prison populations and costs while fostering enhanced social structures. Due to the nature of incarceration in the United States today caused by issues leading to increased incarceration rates, there are methods aimed at preventing the incarceration of at-risk populations.
Due to escalating gang activity and high crime rates in Oakland, California Mayor Jean Quan proposed gang injunctions in Oakland, which were passed in May, 2011. These highly controversial injunctions were only proposed for 2 areas of Oakland – the North side of Oakland and the Fruitvale district. Injunctions were placed in these areas even though the highest crime rates were located in the West Oakland and East Oakland district 6 areas. Opponents of the injunctions cite concerns about the high costs of implementing and maintaining them, as well as the possibility of civil rights violations. They also criticize the motives behind them and raise questions about the actual safety achieved and issues of gentrification. A gang injunction is a court-issued restraining order that prohibits named gang members from participating in a variety of specified activities. A "gang member" is defined as an individual who knowingly belongs to a gang, i.e. has specific intent to be a gang member. Under this definition, gang members have sufficient notice of what constitutes a prohibited "gang association." The goal of gang injunctions are to prevent criminal activity before it occurs and to end the problems that already exist.
