First of all there should'nt have been pre-conditions of any kind. India should have remained firm with the Portuguese Govt. on his extradition, that they were dealing with a terrorist and there would be no concession of any sort on his trial. Abu Salem is directly responsible for the death of innocent civilians. He must be punished for his crime, there are so many people waiting for justice to this heinous crime.
I firmly believe that India should remain firm on capital punishment for Abu Salem. Also, all his associates should face maximum penalty.
India should stand firm on extradition of criminals/terrorists all over the world. If all countries cooperate and maintain such treaties then terrorism could be a thing of the past.
