Considering the crime and the consequences, the bastards can cop the full weight of Indonesian law and serve it in their prisons, not ours.
Having said that, I don't believe that anyone has the right to take another's life. Therefore, I can't support a death sentence for anyone. However, life in prison, that is, you die there ... eventually, seems appropriate for what these low lives were going to inflict on the end users of those drugs.
