Well, let's see, what can be done about it?
As far as I know, India is a democracy, so what you can do is raise your voices and demand a law to be put in place to prevent this. Furthermore you can demand enforcement of this law.
Will this make a difference? I don't know, I am not Indian, so have no idea. But it will make SOME people listen and MAYBE educate a few more.
Doing nothing will do exactly that, NOTHING.
