South India was shielded from invasions and loot by the North India. Hence south has better law and order. Bihar is ruled by OBC, and not Brahmans. 15 years of Lallu Raj has brought it to that state. UP was ruled by Mulayam Singh Yadav, another OBC and hence it is in that state. So you might want to read through the DMK propaganda again carefully and check for correlations. If the sun rises every time you go to work, it does not mean the sun is rising because of you. Reservations can do that to tbe brain sometimes.
