Well, if espionage is an 'accepted' part of international politics, then let the international law treat is as a 'non criminal' act ;-)..
All that I am saying is that we should not be supporting someone just because he is an Indian / Hindu / Sikh / Muslim.. if it were true that Sarabjit was behind a bomb attack,which is a crime, then let him be punished as per the applicable laws. If it can be proved that it is a case of 'mistaken identity', then let him be freed. Supporting someone blindly for the reason that he belongs to our nation cannot be termed as patriotism.
