Why Isn't Bush Being Impeached for NSA Wiretapping?

This is a great article explaining the lawlessness of the Bush administration to spy on us without authorization and appropriately wonders why the hell this is not a major story and grounds for impeachment! Here is an excerpt:

Comey then made clear that he and Ashcroft met, determined that the NSA program lacked legal authority, and agreed "on a course of action," one whereby the DOJ would refuse to certify the legality of the NSA program. Yet even once Ashcroft and Comey made clear that the program had no legal basis (i.e., was against the law), the President ordered it to continue anyway. As Comey said: "The program was reauthorized without us and without a signature from the Department of Justice attesting as to its legality."

Amazingly, the President's own political appointees -- the two top Justice Department officials, including one (Ashcroft) who was known for his "aggressive" use the law enforcement powers in the name of fighting terrorism and at the expense of civil liberties -- were so convinced of its illegality that they refused to certify it.
Does this sound in any way like the behavior of a government operating under the rule of law, which believes that it had legal authority to spy on Americans without the warrants required for three decades by law? How can we possibly permit our government to engage in this behavior, to spy on us in deliberate violation of the laws which we enacted democratically precisely in order to limit how they can spy on us, and to literally commit felonies at will, knowing that they are breaking the law?

How is this not a major scandal on the level of the greatest presidential corruption and lawbreaking scandals in our country's history? Why is this only a one-day story that will focus on the hospital drama but not on what it reveals about the bulging and unparalleled corruption of this administration and the complete erosion of the rule of law in our country? And, as I've asked many times before, if we passively allow the President to simply break the law with impunity in how the government spies on our conversations, what don't we allow?
