You seem to have short memory. Lalu was arrested for the fodder scam and stayed in jail for a long time when your Narsimha Rao was prime minister. After that he was released. The case is still going on. If we go by that logic each Amma politician of the south should be in jail, but instead they enjoy wonderful life. Kumarasamy, Devegowda, Jayalalitha, all recent chief ministers of ghaateeland are all very corrupt people. But except for Laloo, none of these gentlemen ever went to jail.
