In my city, there are estimated 5000 illegal BDs residing. These BDs are hiding in Muslim localities. I dont say that all of them are terrorists. They are actually working in small industrial units located in Muslim localities where working conditions are horrible and wages are extremely poor. No IM will work there. So to keep these units running, Muslim owners user BD migrants. These migrants toil for the whole day in dark, dingy,hot units just for two square meals, a piece of cloth and Rs.10-20/day as wage. Not to say, they are now also being used for terror. Unless IMs realise that they are harbouring snakes, things will not change.
