You left out one important consequence. If they let him off the hook, M Ravi will dislodge Subhas as the 'media' counsel for drug related offences, and perhaps, other capital cases as well. M Ravi's status as a 'human rights' lawyer will take a quantum leap, even though I doubt he studied human rights law as a student. Well, you could not have asked for a better form of publicity than this.
Having said that, I'm not suggesting that M Ravi may have been motivated that way. But the outcome is obvious.
Back to Yong. In fact he was already prepared to serve the death sentence. I read somewhere that the monk or pastor came to speak to him, and he was already geared up for such eventuality. Now with the frenzy over the possibility of a second chance, his mental status will have been severely disturbed. The analogy is like a young recruit who is serving his BMT, and his mind keeps thinking of how to 'keng' out of course. He will surely find the BMT tough because his mind is conditioned in the opposite way.
You're absolutely spot on that the media has been romanticizing Yong, and with the frequent mention of Yong's parents, selling 'parental love'. I would like to read a more detailed coverage of their parental love. How did they bring up Yong ? And how did the upbringing end up with Yong becoming a drug mule ? Drugs suppliers don't just go for anyone in the street. Did the parents even express regret for the way they have brought up Yong ? This would have been a good education for parents of aspiring drug mules, on the importance of proper upbringing.
