Preface: What I say below is cold, callous, and it comes across as extremely racist. I work for large company and we hire a lot of "contractors" which is a politically correct way to say hire a lot of Indian programmers. One of my great friends at work is from Madurai. His wife is lovely and his kids are hilarious. That sounds a lot like saying "I'm not racist, I have a friend who is black!" but it's the best I can do.
Americans don't care about the violence in India because we don't respect your country. We don't consider you an equal. To us, you are just like Iran, Iraq, Pakistan, Syria, and their lot: backwards, undeveloped, and behind the times. To us, you are a lower tier of humans.
France is a civilized country. Americans can go there and feel safe and comfortable. They have laws similar to ours, a government we can respect and (for the most part) trust. We don't fear being detained randomly by French police for doing something that no western-born person would consider against the laws.
India is poor. Dirt poor, literally. Your government is known to be corrupt, and your culture is an embarrassment to human rights. It seems that every week or so there is a story in /r/worldnews about women being raped, having acid thrown on them, and/or beaten. Not to mention the fact that the caste system is still strong as ever. Americans don't care about India because India is a ghetto of a country. It's uncivilized barbarians attacking more uncivilized barbarians. It's the exact same reason that we don't care about violence on the south side of Chicago.
Until you "look like us" and start to act "like us" you will never be a culture we particularly care about. We care about our own, and you aren't one of us.
