Gujarat police on Tuesday filed a chargesheet in the Naroda Patiya massacre of Feb 28, in which over 80 Muslims were burnt alive, in part blaming the victims for bringing the attack upon themselves.In the Gulbarg case too, the chargesheet had said the mobs had turned murderous only after former MP Ehsan Jafri had opened fire upon it.The chargesheet filed by the Crime Branch says the armed crowds that had gathered in Naroda had turned violent after two incidents: Discovery of a ‘‘mutilated body of a Hindu’’; and killing of a person by a ‘‘Muslim driver’’ who drove his Tata 407 mini-truck into the crowd.
