Was that unconstitutional? Or not? Did anyone challenge the action in federal court? Or not?
Are you saying that it was constitutional? Can any state, without even the fig leaf of an unconstitutional secession declaration, seize US government property? I suppose you'll say that they can, since the Constitution doesn't expressly forbid it.
Did anyone challenge the action in federal court? Or not?
No, we didn't challenge the action in federal court. It took a while, but we just came and took them back.
What difference would that have made, given your disregard for the courts? Instead, why not point out what clause of the constitution gave Virginia the right to take federal property without the approval of Congress and without compensation. Can you do that?
