What I'm not yet seeing in the maelstrom around the warrantless spying debate is the implication that this is a very slippery slope.

If this spying on citizens with no Congressional or judicial oversight is allowed to stand, what's next? What will the next civil liberty to be eroded? If the Fourth Amendment can be so easily circumvented, how long before the same is done to the First Amendment? Or the Fifth? Or pick your favorite piece of Constitutional law...

I know this isn't the first step in the steady erosion of our civil liberties, but it's the most reported on and flagrant flouting of the bedrock of our republic to date. This is the one that is catching on and raising ire. And it's a perfect example of the slippery slope - it's all downhill from here if something isn't done swiftly and definitively.

That's the argument that is more likely to sway average Americans, more than simply stating the truth that the President broke the law.
