Yes I can absolutely see it here and in fact I predict it soon enough. These idiots riot over football games, etc. So you just wait until inflation kicks in big time as the economy continues it's fall and/or eventual collapse of the Dollar.
A catalyst that i can see as a possible point of ignition is the inflation that we have right around the corner in our future - predicted to be major to severe. When their welfare or unemployment checks will shrink in value to the point where they just aren't enough to pay for what inflated prices will bring (a $1000/month welfare check today in conditions of extreme inflation will bring it's actual value down to $100-$200 in todays dollars - they'll be starving, etc and riots will follow in rapid order).
I live 35 miles from the nearest town of any size in the mountains of the high desert. The cities will be a nightmare when these riots begin, with mobs torching everything in sight. The military will be required to put it down.
