1) The people killed in Godhra were Indians. The people killed after that were Indians as well. So as a chief minister of an Indian state Modi owes responsibility of both.
2) Lalu Yadav is seen as the prime reason for Indian railways success. Does it mean that he is now free of all Scams ? A lot of criminals get elected everywhere in the country does that mean that they are clean ?
3) Sohabuddin was a known criminal with 56 cases against him. These 56 cases were not registered in a day but over a long period. So it is a fact that he was operating from BJP ruled state for so long, so there is no need to say who was supporting him. When the BJP found that he has become a headache they used the supari killer police to kill him. Now this is just a matter of criminalization of the whole political system.
