Remember what happened during desegregation in the 60's? Whatever else you think of Governor Wallace's views on segregation, he was absolutely CORRECT that the federal government had NO Constitutional authority to do what they did. And what are the sheriffs of a local area going to do when they are bullied by more superiorily armed guardsmen?
I watched intently as Wallace was approached by the Marshal Service and demanded that he step aside or be arrested. I said when that happened the Constitution was no longer binding the Federal Government, we now see the result of that day.
