hang Salem till death.If Portugal took a sign about not to kill, then put this issue internationally, even u indian government can ask UN for opinion then internationally force Portugal to say the word "Kill him". How come portugal is most intrested on selem even he is not belongs to its contry.First shame on indian CBI as they signed on the papers not kiling Salem.If u have any problem, Encounter Salem and tell them he sucided.Use criminal brain for such people, militants. Hell with the Human rights people, who never care about the Person who died in Terrorist attacts. they will just concerned about only the Militants.
