"A stupid diversion of scarce resources from the real target"

The ACLU has filed suit against the National Security Agency for what it alleges is unconstitutional surveillance of Americans. That's the dog-bites-man story. The man-bites-dog angle is that one of the co-plaintiffs is none other than War on Terror enthusiast Christopher Hitchens. From his statement:

We have recently learned that the NSA used law enforcement agencies to track members of a pacifist organisation in Baltimore. This is, first of all, an appalling abuse of state power and an unjustified invasion of privacy, uncovered by any definition of "national security" however expansive. It is, no less importantly, a stupid diversion of scarce resources from the real target. It is a certainty that if all the facts were known we would become aware of many more such cases of misconduct and waste.

We are, in essence, being asked to trust the state to know best. What reason do we have for such confidence? The agencies entrusted with our protection have repeatedly been shown, before and after the fall of 2001, to be conspicuous for their incompetence and venality. […]

The better the ostensible justification for an infringement upon domestic liberty, the more suspicious one ought to be of it. We are hardly likely to be told that the government would feel less encumbered if it could dispense with the Bill of Rights. But a power or a right, once relinquished to one administration for one reason, will unfailingly be exploited by successor administrations, for quite other reasons. It is therefore of the first importance that we demarcate, clearly and immediately, the areas in which our government may or may not treat us as potential enemies.
