So here's the thing with riots. Once it starts, non-locals join. They don't know that "John's Market" gave formula and diapers to a local woman whose income was interrupted, or that that little used car lot on the corner is the result of a neighborhood family's 30 years of sacrifice.
The police stations will be rebuilt with thicker, fire-resistant walls within a few months. But the owners of those local businesses are probably down for the count.
Now do you get why we should not cheer the rioters on? Imagine your neighborhood, only without any businesses, and you have to take the bus to get anywhere.
