see this is basically fight between the CPIM cadres who have been driven out of Nandigram by Jomi Bachao Uched Committe members and JBUC to regain their lost ground and homes...i think Laksham Seth and CPIM cadres were desparate to get back at the JBUC members who have eroded their support base..police was made the scrapegoat in this...while Buddhadev shuld take moral responsibility for the massaccre he shuld not step down..
