Morchjanpi incident happened in 1979, and was against Bengali settlers from across the border. Keshpur happened in 2002, and was against TMC supporters. Guess who was in power both times? CPM. Now you still wonder why nothing happened? But this time people/parties are more aware and vocal and active. Once they are voted out, all these skeletons will come tumbling out. Why else are they so scared of ever losing power, and so will try everything vile and indecent just to stay in power. It's really up to WB to throw them out now.
