If a riot breaks out, it will be in the same 3 cities its always in. No loss for the rest of the country. No one else will notice either if it wasn't for the 24/7 media frenzy that would cover it.
I can easily see there being about 10 major metro areas where rioting MIGHT occur....
Chicago
L.A.
Miami
Detroit
Cleveland
Oakland
Philly
Washington D.C.
Atlanta.... to name a few. Maybe even Indy....
