Prime Minister Narendra Modi chose the ashram of the apostle of nonviolence, Mahatma Gandhi, to issue a stern warning on Thursday against killing in the name of cow protection and the growing culture of violence in society at large. "Nobody can kill in the name of cow. Whether anybody is guilty or not, law will take its own course. No person is allowed to take the law in his hands," Modi said in his address at Gandhi's Sabarmati Ashram in Ahmedabad.
