Introduction

Intriduction The term criminal policy is equivalent to the French word "Politique crimnelle" and has a much wider meaning than criminal policy, in terms of vocabulary, it means "planning" and thinking of a solution for the criminal phenomenon, which in the realm of criminal policy, includes deviation And it becomes a crime, it has come. In general, the meaning of participatory criminal policy is to examine and study the place that has been given to civil society in the criminal policy of a country by giving a role to the offender, the victim and especially the whole society or people (Delmas-Marty, 2002: 24). In the investigations carried out in this city, despite effective police activities in preventing crime, there is no codified collaborative criminal policy, and it seems that most of the prevention activities are pursued on an ad hoc basis, therefore, considering the necessity and importance of collaborative criminal policy in creating order and security and preventing crime, it is necessary to draw these policies in a clear and specific way in this city. The dispersion and diversity of the rural and urban population in this city, the role of clans in the occurrence of crime, the increase in population, the presence of seasonal and non-native workers and the number of foreign nationals (afagheh) and the effects of such issues on the amount of crimes, the importance of drawing this collaborative criminal policy. It has doubled. On the other hand, no research on the above topic has been conducted in any of the cities of Qazvin province, which shows the current situation, so this also reveals the necessity of research from this point of view.
 

Methodology

The research is developmental-applied type. The data was collected through a mixed method (qualitative/inductive and quantitative/descriptive thematic analysis method). The type of mixed method was exploratory. In the qualitative part, the purposeful sampling method has been used, based on this, 24 law enforcement experts of Qazvin province and Buin-Zahra city have been identified, and semi-structured interview tools have been used to extract data, and Max Kyuda software has been used for data analysis. In the quantitative part, in order to measure the findings and to know the current situation, a researcher-made questionnaire tool was used. The statistical population of this department is a wide range of experts from the city, province, Police headquarters who play a role in the field of police management of the city. According to Cochran's formula, 68 of them were selected. The validity of the report has been confirmed through logical validity, construct validity and reliability through Cronbach's alpha. Data analysis by providing tables and interpretation of findings through spss software, runtest test was used to check the randomness of data distribution and Friedman test was used for prioritization.

Results

The findings of the qualitative part showed that the collaborative criminal policy of action consists of 5 main themes and 39 sub-themes, and the reactive collaborative criminal policy consists of 4 main themes and 40 sub-themes, so in total, the collaborative criminal policy of the police in this city is used to prevent crimes. It consists of 9 main themes and 79 sub-themes. The prioritization of the themes also showed that according to the weight of the themes, the role of the local community is in the first place with a weight of 3.98, restorative justice is in the second place with a weight of 3.82, and community-oriented prevention is in the third place with a weight of 3.62.
 

Discussion

The interview data showed that the criminal policy of the police in this city can be applied in two axes of active and reactive cooperative criminal policy. In the collaborative crime policy, the action that takes place before the crime occurs, 5 axes of education, cultural programs, local community, community-based prevention and inter-organizational cooperation have been considered. The themes of this policy include measures and actions that aim to reduce or eliminate crime-causing factors in the social environment. In the cooperative crime policy of the police in this city to prevent crime in general, 4 axes of restorative justice, disciplinary, situational and criminal prevention have been taken into consideration. Regarding the first axis, i.e. restorative justice, the police plays the role of a facilitator, the offender, the victim and the members of the local community cooperate to solve the problem with the help of the police, issues such as mediation, shaming, avoiding labeling, etc. are taken into consideration.

Conclusion

The findings of the research have identified activities of  the preventing crime in this city that are carried out by the police in the form of collaborative crime policy. These policies are divided into two categories: proactive and reactive criminal policies. The developed policies can be used by the police as a guide. Their prioritization shows which policies are more effective to be used in current programs.
