One obviously feels sad for Sanjay, he is clearly repentant, and is that not the purpose of prison.
On the other hand justice must be done and must be seen to be done, alas a large section of our population routinely evade justice, our new president, other sundry politicians, big businesses like the Ansals and the Uphaar tragedy, the lawyers in the Nanda BMW case, too many to mention.
If Sanjay was convicted to 6 years in the environment of all these above mentioned also facing prison time it would be justice, at the moment its just selective, which makes him more of a victim then a accurate representative of RXC Indian justice whatever your status.
