On what basis have you arrived at the conclusion that the law and order problem in Mahrashtra is due to the outsiders? It could very well be the case that there are crime figures are equally distributed among all communities.
I will agree that it could have been the case that crime was less about 30 years ago but that is not because of less outsiders but because the disparity between the rich and poor was not as much as it is today. It has been shown with substantial evidence in the western world that crime is directly proportional to the disparity between rich and poor.
