Rajeev, your point is well-taken. But there are holes in the 'greater common good' approach. Did the police take money for doing this or did they consider this a 'social work' ? What was the reason for Sohrabuddin to blackmail the marble lobby ? Is there a politician-marble lobby-police nexus that drives these killings ? Why is it that majority of the encounters happen to one religious community ? Are we running short of hindu extortionists ? Too many angle to investigate. If it is indeed that Vanzara was acting for 'greater common good' and not for money, you may have a point. What does it mean for the society as a whole ? How many encounters can be justified as 'greater common good' ? Who decides what is good for the common man ?
