Even after 7 days of the murder of the respected scholar Professor MM Kalburgi, we are nowhere closer to knowing why he was killed, or by whom. This week on Truth vs Hype we examine some of the commonly held theories : Was he killed because of his questioning of orthodoxies in his own community of Lingayats? Or because he rubbed Hindutva -waadis the wrong way? Or was it a property dispute within his family? Or like the recent murders of other intellectual dissenters, is there a fear that his murder too, will remain inconclusive?
