Hot spots of crime, and the criminology of place more generally, deviate from the traditional paradigm of criminology, in which the primary assumption and goal is to explain who is likely to commit crime and their motivations, and to explore interventions aimed at reducing individual criminality. Alternatively, crime hot spots account for the “where” of crime, specifically referring to the concentration of crime in small geographic areas. The criminology of place demands a rethinking in regard to how we understand the crime problem and offers alternate ways to predict, explain, and prevent crime. While place, as large geographic units, has been important since the inception of criminology as a discipline, research examining crime concentrations at a micro-geographic level has only recently begun to be developed. This approach has been facilitated by improvements to data availability, technology, and the understanding of crime as a function of the environment. The new crime and place paradigm is rooted in the past three decades of criminological research centered on routine activity theory, crime concentrations, and hot spots policing.
The focus on crime hot spots has led to several core empirical findings. First, crime is meaningfully concentrated, such that a large proportion of crime events occur at relatively few places within larger geographies like cities. This may be termed the law of crime concentration at places (see Weisburd, 2015). Additionally, most hot spots of crime are stable over time, and thus present promising opportunities for crime prevention. Crime hot spots vary within higher geographic units, suggesting both that there is a loss of information at higher levels of aggregation and that there are clear “micro communities” within the larger conceptualization of a neighborhood. Finally, crime at place is predictable, which is important for being able to understand why crime is concentrated in one place and not another, as well as to develop crime prevention strategies. These empirical characteristics of crime hot spots have led to the development of successful police interventions to reduce crime. These interventions are generally termed hot spots policing.

The ability of the police to assert social control and reproduce social order depends, crucially, on the capacity to use force to achieve these ends—whether when restraining someone attempting to self-harm or shooting dead an armed terrorist. But what do we know about police use of force in the United States and England and Wales? Why does unjustified police use of force occur? And why do citizens have different views on the acceptability and unacceptability of various forms of police violence?
Gangs have been subjects of extensive empirical research since the 1920s. Scholarly interest in gangs was largely due to gang members’ increased likelihood of engaging in delinquent behavior. Gang members have been involved in criminal activities ranging from drug dealing to theft, property offenses, gun violence, and homicide. In the 1980s, there was nationwide concern about gangs as violent gang-related crimes increased and drew media attention. As a result, important legislation was implemented that made gang membership illegal. These policies were designed to curb gang involvement and de-escalate gang violence. The legislation included civil gang injunctions, the development of gang databases, and the formation and strengthening of gang task force units. Indeed, the policies resulted in an increase of gang unit officers focused on mitigating gang involvement and gang crime. Officer strategies focused on stopping, detaining, and arresting individuals who often fit certain stereotypes. Specifically, officers routinely based gang-related encounters on suspects’ race, age, clothing, gender, and geographic location, focusing mostly on young men of color in economically depressed neighborhoods. Perhaps unsurprisingly, a number of problems and concerns related to aggressive and biased police behavior surfaced, resulting in questionable outcomes of gang suppression. Research suggests that directed patrols and removing leadership might not be effective. Instead, alternate policies should include policing in conjunction with support from community-based nonprofit organizations and research that accounts for gang members’ experiences of law enforcement strategies.
