This study analyzes the impact of different policing tactics carried out in hot spots.
The most common problem-oriented policing strategies utilized included situational prevention measures, such as maintaining railings and gates, increasing street lighting, and using traffic barriers.
Officers worked with shopkeepers, business owners, and landlords to implement crime prevention measures and security protocols at establishments.

This is a police hot spot patrol intervention. The officers carried out daily 15-minute patrols at the designated hot spots while they were not answering emergency calls. One to six hot spots were assigned to the officers, who were responsible for visiting those locations every 2 hours. Interventions were suggested to the officers by computers inside police vehicles.

The main objective of the Compstat management system is to develop specialized solutions to fight crime by improving the management of police resources and the functioning of police departments.
The system focuses on four main components:
1) Timely and accurate information and intelligence;
2) Rapid deployment of resources;
3) Effective tactics; and
4) Permanent monitoring.

This is a social reintegration program to assist incarcerated individuals in the transition process between the closed system and the community.
The service has a less rigid housing structure and allows inmates to work in the community with access to a salary. In addition, the program offers vocational training courses, such as vehicle repair, building maintenance, food services, electronics, printing, carpentry, gardening, hairdressing, plumbing, and cleaning.

This is an experiment to evaluate the effectiveness of alternative methods of instant testing to detect drug abuse and determine how the different methods affect relapse and recidivism rates in cases of parolees with psychoactive substance use problems.
The evaluation considered three models:
1) Random drug testing with immediate results and immediate sanctions;
2) Random drug testing with later results and sanctions; and
3) Routine (non-randomized) procedures with later results and also slow sanctions.

The social worker must conduct motivational interviews, a risk and needs assessment, and joint planning of strategies for access to community services. The supervisors monitor the reintegration of the prisoner into the community, which ensures the continuity of the planning devised during the prison monitoring period.

This is a strategy based on the interview method as the basis for gathering information, rather than the accusatory interrogation method.

To do this, researchers compared the accusatory method, common in the United States, with the information-gathering method, common in England [1].
This difference is observed through four elements:

This is a Cognitive Behavioral Therapy program for the treatment of incarcerated individuals. The objective is to develop interpersonal communication skills and confront thought patterns that can lead to problematic behaviors.

This is an automated ballistics image and analysis system that makes up a computerized database of projectiles and weapons used in crimes. The aim is to reduce the time spent on ballistics analyses and to instrumentalize and facilitate the work of forensic experts during the identification of this evidence for use as information in investigations and trials.
