The three types of criminology in chapter none include radical criminology, critical criminology, and peace making criminology. Radical criminology is a criminology branch that consists of social and economic conditions which in this case causes crime. That is, individuals who are less fortunate regarding their social and economic status are more prone to committing a crime. Critical criminology consists of the capitalist system and challenges the traditional understanding and the false beliefs about criminology and crime. Peace making criminology is based on the idea that there is the need for both citizens and social control agencies to work together to not only solve problems but also to reduce crime. The components of this type of criminology include a peace model, participatory justice, and restorative justice. The peace model provides effective ways that each party could have a shared census on critical issues. Participatory justice, on the other hand, works on using resources from local communities rather than traditional forms of official intervention.
Conflict theories which suggest that social conflict and its manifestation in the community is the causes of crime hold the implication that readdressing injustice that will end the marginalization of individuals who are economically and politically disadvantage could help in reducing the crime rates. The policy implications related to social conflict theory show a clearly that social change regarding redistribution of wealth within the society would help to reduce the crime rates. Other social conflict theories such as peace making criminology suggest the use of conflict resolution as a way of reducing crime while others suggest the need for analyzing and recognizing the consequences of to the victims. One common thing is that the change in the social dynamics is essential to ensure that the crime rates decrease.
