Violence is a social problem. Reviewing all available publications, articles, scientific research, literature, advertisements and media articles, they all use the sentence "Violence is a social problem". This is indeed so because the consequences of violence, of any form, are reflected on a larger group of people. As a society, according to the Convention on the Rights of the Child, we are obliged to do all the activities for the prevention of violence of any form. Prevention of violence must be carried out continuously from the earliest childhood. If prevention is effective, the number of violent incidents in society will also decrease. Children learn from adults, and adults forget that children are watching and imitating them. The hardest part of any institution is to go into someone's home and teach parents how they should raise their children and how they should behave, but the cooperation of institutions such as schools, police, social welfare institutions, health, courts and family-oriented associations, children and young people can influence the direction of children in the right direction, i.e. in the direction of living without violence. The structure of this paper refers to community policy, educational staff of primary schools and ways to prevent violence among children and young people. According to the opinion of the educational staff, the role of the police in preventive programs MAH2 and PIA in order to prevent violence is accepted and they are considered important lectures. Cooperation between the police and educational staff is desirable and achievable, and by introducing the police into the community, cooperation is strengthened by reacting and guiding ways to solve problems. The role of the police in the community after almost 20 years of work has gained its meaning and acceptance by society, as well as the improvement of local community relations in solving problems. Further action and continuous implementation of the MAH2 and PIA programs will try to reduce the number of violent behaviors among children and young people.
