Geechee, your demand for equal treatment is legitimate. But people have different ways to look at crimes. Rulers of the countries you mentioned took these actions as part of their own security policies which resulted in killing of some innocents which many view as crime. In case of Modi, however, it was not a holy war by any means. He just allowed the brutality against a section of people out of his own prejudice. Modi is generally condemned for his non secular attitude. I would consider winning elections a clean chit for Modi if majority was on recieving side of the carnage.
But, then, the greatest virtue given to man by God is the ability to forget and move forward. Those who suffered in the riots can forget the event but cann't forgive Modi...
