Against the backdrop of questions raised by BJP over his earlier silence on 2002 Gujarat riots, Bihar Chief Minister Nitish Kumar on Tuesday (April 16) appeared to attack Narendra Modi, saying maintenance of law and order was state government's responsibility. Kumar's response came after RJD Chief Lalu Prasad asked if the Chief Minister was genuinely opposed to Modi why did he not quit as the Railway Minister in the Atal Bihari Vajpayee government after the Gujarat riots in 2002.
