The tornado deaths in Indiana only reinforce my hypothesis: Natural disasters don't kill people...poverty in the path of natural disasters is what kills. A mobile-home park was the worst-hit neighborhood in the path of the tornado.
Poverty is also the root cause of the riots in France. Yes, it started as a cultural thing, but the widespread violence is really about economics.
