India, which claims to be a democracy, must bat for free speech, privacy and expression. It is funny that China, often branded as an autocratic country, for whatever reasons, is doing it.
Pretty much every one of those cases is far less defensible than an indictment of Snowden would be (i.e. there is literally no ethical ground to stand on in any democratic society in these cases, whereas one can conceive of a reasonable devil's advocate argument for Snowden's case). India's recent record on free speech is pretty abysmal, unfortunately. It's a nice thought, but I don't see why they would go out of their way and stick their neck out diplomatically to protect it in Snowden's case.
Immediate edit of a typo: "less defensible" --> "more defensible"
And to be 100% fair I would say that India is very a democracy, and that's something they should be very proud of as a nation.
