I disagree. Yes, there are freak deaths in India by its own standards. People die without being able to afford a nominal medical fee etc. I'm not at all denying that.
But, this is whole different thing, where individual's frustration and wrong perceptions results in death of people, which is not at all a case in India (or not as frequent as US gun killings).
Your point of poor people dying has nothing to do with any individual in India. It is a result of our whole political system which is designed in such a way that it is not easy to get solutions for seemingly straight forward things.
The closest thing which is similar to this incident is attacks based on caste which is common in India, but that too are not random, as victims are not taken by surprise when they are attacked/killed. Mostly they are overpowered by small group of narrow minded individuals, resulting in freak deaths.
I'm not sure if you are from India, and if yes from which part, as I really don't get the "nativists in Mumbai/Bengaluru/Hyderabad" part. I'm also not sure what you mean by nativists in India, as it may signify one of 100 things, depending on which part of India you are from.
Again, I'm not saying there are no freak deaths in India. It is common in every corner of the world where there is more than one man. But, death by an individual in a public setting is not common and that too by a gun is almost impossible in India. That was my whole point.
