He has suffered 12 years of public "Modi-bashing" since the time of the riots but says that he had decided early on to "let the media do its work; there will be no confrontation".
"I never waste my time in confontation", the BJP's prime ministerial candidate is quoted as saying in a just-published biography written by a British author and TV producer Andy Marino.

Marino says in the book "Narendra Modi; A Political Biography", published by Harper Collins, that he was given detailed access by Modi whom he accompanied aboard his helicopter during his campaign rallies and interviewed him over several weeks.
On 2002 riots, Modi says, "I feel sad about what happened but no guilt. And no court has come even close to establishing it."
The 310-page book deals with the riots in some detail with "hitherto unpublished, authenticated documents".
It discloses that after the riots Modi wanted to resign as chief minister but was prevailed upon by the party to continue.
Marino says that the BJP strongman had confided to him "possibly for the first time in an on-the-record interview, that he no longer wanted to be the chief minister after the riots because he had decided it was unfair on the people of the state who had been subjected to extreme abuse because of him".
