I don't have much to say on the topic, other than to point you to a very interesting post on the ACLU blog site. This quote jumped out at me:
As the court held in United States v. Robel, "It would indeed be ironic if, in the name of national defense, we would sanction the subversion of one of those liberties … which makes the defense of the Nation worthwhile."
This is the crux of my concerns about the actions of this administration. If you sacrifice all that is American in the name of "security," then what's the point of having America? If you systematically disassemble the Constitution, then what is the basis for this country? I find it extremely arrogant and short-sighted that a few rightwingnuts should think themselves smarter than the Founding Fathers to the extent of grossly rewriting the foundations of this Republic.
