The costs of these looters won’t end with a store or two in Ferguson.
I used to be in the insurance business. Property and Casualty Insurance companies are very attuned to risk management. If they believe that exclusions for riots aren’t sufficient then they will be very leery of insuring properties all over the country that might be exposed to this type of risk.
The resulting risk management could result in higher premiums or simply refusing to insure properties which are in high risk areas. It could lead to calls for a federally funded insurance pool for these risks.
That's also called a bail-out, via OUR tax $$, no?
