Most of train robberies in other state are agin triggered by none other than Bihari / Bhaiyaas. Last year,in mumbai, the people who were caught for local train robbery, were mostly biharis. They just loot and run away back to bihar/UP. Instead of providing security to railway, why laly/mayawati/nitishkuamr cann't provide jobs to their own people? These jobless people get migrated to other states and creates law and order problems.
