Sunanda, I think you are getting it wrong or atleast using convenient data to prove a point which maynot be as strong as you make it out to be. For every incident, in year 2008, of atrocities on SC/STs and such, there could be 10 incidents representing exactly the opposite if only you bothered to go out and find out. But you may not 'coz that doesnt serve the purpose of your article. Much has changed beyween 1950 & 2008, though the pace of change may definitely be lesser than desired.
