Mamata Banerjee should not have poked her nose with half-baked knowledge and make polarising statements like she did yesterday and that is what is highly condemnable. For anyone who is in the know of political developments in Assam, such wild statements are at the least laughable. Updating the NRC is an attempt at bringing a closure to the vexed foreigners' issue in Assam, an issue over which thousands have lost their lives in Assam. Even though there are many daunting challenges after the final NRC is published and there are many loose ends to tie.
