Very interesting article at Wired. Top Secret: We're Wiretapping You:
It could be a scene from Kafka or Brazil. Imagine a government agency, in a bureaucratic foul-up, accidentally gives you a copy of a document marked "top secret." And it contains a log of some of your private phone calls.

You read it and ponder it and wonder what it all means. Then, two months later, the FBI shows up at your door, demands the document back and orders you to forget you ever saw it.

By all accounts, that's what happened to Washington D.C. attorney Wendell Belew in August 2004. And it happened at a time when no one outside a small group of high-ranking officials and workaday spooks knew the National Security Agency was listening in on Americans' phone calls without warrants. Belew didn't know what to make of the episode. But now, thanks to that government gaffe, he and a colleague have the distinction of being the only Americans who can prove they were specifically eavesdropped upon by the NSA's surveillance program.
No one else has been able to challenge the legality of unwarranted wiretaps because the only evidence that it happened is in the hands of the organization committing the crime:  the NSA.

And all they say is, "Neener neener neener!"

So what?  They're busting terrorists, so they should be able to skirt the law, right?

It depends on how you define "terrorist," now doesn't it?
