mr hanif, It is well known that mr karunakaran hadnt got any ample proof that rajan was a naxalite.His killing was a act og vengeance.Rajan and his friends did a skit which criticized the injustice did by the govt in the name of emergency.the real perpetrators of crime are very well alive and kicking.I personally know one of them and currently he is a high ranking officer by one of the largest engineering frims in India.So before you poke finger at anybody please think twice.
