Criminology of Place Hot spot policing is based on the idea that certain criminal activities occur in particular areas of a city. According to researchers, crime does not spread throughout the city, but is concentrated in small places where half of the criminal activities take place (Braga, chapter 12). Additionally, numerous studies have demonstrated that hot spots show significant positive results, suggesting that when police officers focus their attention on small, high-crime geographic areas, they can reduce criminal activity (Braga, Papachristo & Hureau, I press). According to researchers, 50% of calls received by the 911 center are generally concentrated in less than 5% of locations in a city (Sherman, Gartin and Buerger, 1989; Weisburd, Bushway, Lum and Yang, 2004). That is, crime action often takes place at the street level, not the neighborhood level. Thus, police can target a significant proportion of city-wide crime by focusing on a small number of high-crime locations (see Weisburd and Telep, 2010). In a meta-analysis of experimental studies, the authors found significant benefits of the hotspot approach in treatment compared to control areas. They concluded that fairly strong evidence shows that hot spot policing is an effective crime prevention strategy (Braga (007). Importantly, there was little evidence to suggest that hot spot policing Spatial displacement was a major concern in hot spot interventions. Crime did not simply move from hot spots into neighboring areas (see also Weisburd et al., 2006). Crime hot spots? Concerns remain about the effectiveness of policing in hot spots and what police officers should do to effectively reduce crime. to know what they should do...... middle of paper ......by offenders and geographic areas Even though Operation Ceasefire was carried out as an intervention to city ​​scale. in Boston, the message of deterrence was aimed only at a small audience rather than at the general public. Furthermore, the operation was carried out by establishing explicit cause-and-effect links between the behavior of the target population and the behavior of the authorities (Braga et). al., 2001, p. 201-202). The authors said the implemented program was credible because it was realistic to believe that police officers could target gang members living and delinquent in hot spots. For this reason, despite evaluations that use the entire city as the unit of analysis, in reality programs are more focused on specific offenders and geographic areas within these broader contexts. They also share many commonalities with other effective geographically targeted policing strategies...
