Former IPS officer KPS Gill, who was security adviser to Narendra Modi in 2002, reckoned that the "Gujarat riots took place as the Gujarat Police was divided on communal lines", says a new book. "From my first-hand experience of Gujarat situation, I can say with conviction that Gujarat riots were not the failure of Mr Narendra Modi; instead it was the failure of Gujarat cops as well as the intentions of the neighbouring states which had then denied forces to Gujarat when the riots started," the book quotes Gill as saying.
