Too many people in too small an area with too few resources. There are parts of the Indian culture that are interesting and beautiful, but so very thankful I do not live there.
I'm not at all condoning what happened but that many people with so little deodorant makes people antsy.
For the non-Indians, how much would it take to get you to go to India and run with these guys in that river? $50K? $100K? Whatever happens in the Ganges, stays in the Ganges. http://www.bbc.co.uk/news/world-asia-india-21010629
