PRISM is a good example of the difference between America and India. One, there's vocal and empowered opposition, opposition granted relief by the courts from time to time.

Numerous cases have been filed against the NSA in regards to PRISM, with nothing even remotely close to success. They are invariably thrown out because the NSA acting illegally or unconstitutionally can only be challenged by somebody with standing. You only have standing if you can prove you have been surveilled and affected because of such. Nobody can prove standing, so it's impossible to legally challenge a likely illegal program. Great system we have.
