The problems can be resolved using the principle of restorative justice, that is, the sense of justice for each party involved in the problems can be realized. Such overcoming involves victims, perpetrators, victims' families and the community as well as the relevant parties in order to reach a fair agreement and settlement.The research focuses on restorative justice in Polri.
