Nice thought, but the reality is that that might not happen?
When Stationed in Korea, in the 70's, there were race riots going on in the US.
Those of the same ethethinticy, decided to support their brothers by not going to work.
MP's with tear gas convinced them to leave the barrakcs, and get medical care.
Unfortunatly, the Military is not so cut and dry now.
That is true but if things ever did get that bad, I don't picture a lot of our military being willing to fire on family, friends or neighbors. Some will just follow orders, some will fight if they are attacked, some will say screw it and go home, and others would side with the people. No way if it ever gets that bad will there be a real winner, no matter what happens.
