摘要:This research was made in the city of Barcelona with a sample of 734 subjects. It analyzes the vision of victims of crime and no victims about the social effects of prison and alternative measures in the criminal reinsertion and the crime reduction. The second part of this article emphasizes the social degree of knowledge about the alternative measures. The results show that the victims have a positive vision of alternative measures in front of the traditional prison and a better information and knowledge. But both groups didn’t show differences in the vision of prison as a means of rehabilitation or crime reduction.
