Now, if you think this was some kind of routine police enforcement action that got out of hand and that the company boss had nothing to do with it, then I don't think you know how things work, especially in places like India. The police chief and top brass would most likely be part of the same social circles and would look out for each other's interests. In corrupt places, the power of the state is always readily available to the rich and powerful, whether it's quelling a labour dispute in India or a low-interest Fed borrowing window.
Now, when I first read the title I was struck that a company president would be killed by workers, but after reading the article, it suddenly makes a lot more sense, doesn't it?
Now that I think about it, it's also pretty sad that the killing of a labour activist doesn't surprise or shock me, but the killing of an executive does.
